| Title |
Himalayas Exaggerated (Draft) |
| Abstract |
Satellite photographs (from Terra-MODIS) and computer-generated models help visualize Bangladesh's place in the world. Located in South Asia, it is virtually surrounded by India and the Bay of Bengal to the south. But in many ways, the country's fate is dominated by the world's highest mountain range looming to the north-the Himalayas. |

Floods in India and Bangladesh |
| Description |
Large parts of Bangladesh (center) and India (left and upper right) are underwater in this image from the Moderate Resolution Imaging Spectroradiometer (MODIS) on the Terra satellite captured August 6, 2003 (top image). The images have been enhanced to show the presence of water, which appears dark blue, while vegetation remains green, and clouds are white (liquid water) or light blue (ice crystals). Snow on the Himalaya Mountains, which run across the top of the image, is bright blue. Compared to an image captured on March 5 (bottom) before the onset of the seasonal monsoon, rivers appear to be out of their banks and the terrain surrounding the Ganges River (flowing in from left edge) and the Brahmaputra River (flowing in from upper right) is waterlogged, with standing water giving the landscape a bruised appearance. Although flooding during the monsoon is normal, many parts of India, Bangladesh and Nepal are experiencing more severe flooding than usual.

Floods in India and Bangladesh |
| Description |
Intense monsoon rains beginning in mid-June combined with melting snow running out of the Himalaya Mountains to trigger extensive flooding across Bangladesh and northeastern India at the end of June and beginning of July 2004. This Moderate Resolution Imaging Spectroradiometer [ http://modis.gsfc.nasa.gov ] (MODIS) image, acquired on June 28 by the Terra [ http://terra.nasa.gov/ ] satellite, shows just how widespread the floods are. The image includes an area that is about 2000 kilometers wide, and dark blue water, not present in an image taken on May 8 during the dry season, covers much of the scene. In this false-color image pair, water is dark blue, vegetation is bright green, and clouds are light blue. Bare earth is tan. In the flood image, the sun is reflecting off the surface of the water, creating a bright white patch near the center of the image. As of July 10, 55 people had died in the floods in northeastern India, and hundreds of thousands more have been affected. In Bangladesh, high waters stranded nearly half a million people, according to news reports.

A web of dark blue and black flood water covers the region surrounding the Bangladeshi capital, Dhaka, in this image, acquired by the Moderate Resolution Imaging Spectroradiometer [ http://modis.gsfc.nasa.gov ] (MODIS) on NASA?s Terra [ http://terra.nasa.gov/ ] satellite on August 3, 2004. The Ganges River runs into the image from the upper left corner, and the Meghna River flows down from the upper right corner. The flood waters are slowing draining away, though the capital city remains partially submerged. New reports say that the floods have claimed 740 lives in Bangladesh, and the number is expected to rise as water-borne disease spreads. The floods were triggered by heavy monsoon rains in June and July. The above image is in false color to highlight the flood waters. Vegetation is bright green, water is dark blue and black, and clouds are light blue. The high-resolution image is at MODIS? maximum resolution of 250 meters per pixel, though the image is available in additional resolutions [ http://rapidfire.sci.gsfc.nasa.gov/subsets/?FAS_Bangladesh/2004216/FAS_Bangladesh.2004216.terra.721 ].

Haze and Sediment in Bangladesh and India |
| Description |
More haze hugged the Himalaya Mountains on January 21, 2007, clouding the skies over northern India, Nepal, and Bangladesh. In the south, thick sediment clogged the mouth of the Ganges. During the Northern Hemisphere winter, haze often collects at the base of the mountains, trapped there in part by weather systems. Sediment flowing from the mouth of the Ganges is a natural occurrence, but it can be exacerbated by land-use changes as an area industrializes. The Moderate Resolution Imaging Spectroradiometer (MODIS) [ http://modis.gsfc.nasa.gov ] on NASA's Terra [ http://terra.nasa.gov ] satellite took this picture on January 21, 2007. In this image, the haze appears as a dingy, gray-beige fog over the region, pushing south into Bangladesh. Skies are clearer to the south, and this image offers a clear view of the Sundarbans [ http://en.wikipedia.org/wiki/Sundarbans ] that straddle the border between India and Bangladesh. In the east, the land surface vaguely resembles marbled paper [ http://www.gilesorr.com/Venice/marbled/ ]—the result of the same continental collision that formed the Himalayas.

| Title |
Deadly Floods Sweep Across Northeastern India |
| Description |
On October 13, 2004, the rivers of northeastern India and Bangladesh remained swollen after a tropical depression dumped heavy rain over the region for several days the previous week. The storm is being called the worst non-monsoon storm in a decade, and the floods it triggered were deadly. To date, over 150 people have been confirmed dead as a direct result of the floods, according to media reports. This pair of false-color images, both acquired by the Moderate Resolution Imaging Spectroradiometer (MODIS [ http://modis.gsfc.nasa.gov ]) on NASA's Terra [ http://terra.nasa.gov/ ] satellite, shows the extent of the floods. The most deadly flooding occurred in the Goalpara district of India's Assam state, shown in the top right corner of these images. The largest loss of life occurred in floods along the Jamuna River [ http://earthobservatory.nasa.gov/NaturalHazards/natural_hazards_v2.php3?img_id=12522 ] and in the nearly Himalayan foothills. However, as the image taken on October 13 shows, other rivers were also flooded. The normally wide Brahmaputra has expanded further, and to its southeast, Bangladesh's Chalan Bil River is also swollen. In West Bengal, India, on the left side of the image, the Hugli River looks flooded. The large images provided above have a resolution of 250 meters per pixel. Both the October 13 [ http://rapidfire.sci.gsfc.nasa.gov/subsets/?FAS_Bangladesh/2004287 ] and the October 2 [ http://rapidfire.sci.gsfc.nasa.gov/subsets/?FAS_Bangladesh/2004276 ] images are available in additional resolutions and formats, including a true-color view of the scene. In the above false-color images, water is dark blue and black, clouds are light blue, and vegetation is green.

Haze South of the Himalaya
| Title |
Haze South of the Himalaya |
| Description |
A gray pall of haze and pollution filled the skies over much of northern India and Bangladesh on December 1, 2003. Air pollution tends to ?pool,? or collect, along the southern edge of the Himalayas, where the mountains are so tall they effectively block the southern air mass from spreading northward over southeastern Asia. This true-color image was acquired by the Moderate Resolution Imaging Spectroradiometer [ http://modis.gsfc.nasa.gov ] (MODIS) aboard NASA?s Terra [ http://terra.nasa.gov ] satellite.

Pollution over Bangladesh and India |
| Description |
In early December 2002, a thick haze sat over the lowlands of northern India and Bangladesh. The above true-color image of the smog was acquired by the Moderate Resolution Imaging Spectroradiometer (MODIS) instrument, flying aboard NASA?s Terra spacecraft. Notice the sharp contrast between the polluted air in Bangladesh and the clean air north of the Himalayan Mountains. The mountains keep the low-lying smog from heading north. The smog in the image is largely man made and is likely due to people cooking over open fires, driving cars with poor emissions control systems, and burning fallow fields and garbage.

The skies over northern India and Bangladesh have been filled with a thick, gray layer of smoke and haze for most of December 2002. In this particular scene, acquired on Dec. 30, there appears to be a low-lying cloud (or perhaps ground-level fog, brighter white pixels) blanketing much of the region south of the Himalayas. The particulate pollution over the region may have served as ?seeds? (or cloud condensation nucleii) to help form this cloud. The smaller white patches to the north are the snow-covered peaks of the Himalayan Mountains. Image courtesy Jacques Descloitres, MODIS Rapid Response Team, NASA GSFC |

The skies over northern India and Bangladesh have been filled with a thick, gray layer of smoke and haze (gray pixels) since late November 2002. In this particular scene, acquired on Jan. 10, 2003, there appears to be a low-lying cloud (or perhaps ground-level fog, brighter white pixels) blanketing much of the region south of the Himalayas. The particulate pollution over the region may have served as ?seeds? (or cloud condensation nucleii) to help form this cloud. These layers of haze and cloud may be contributing to the unusually cold conditions currently being experienced in Bangladesh. The smaller white patches to the north are the snow-covered peaks of the Himalayan Mountains. This true-color image was acquired by the Moderate Resolution Imaging Spectroradiometer (MODIS) aboard NASA?s Terra satellite. The high-resolution image available here is 500 meters per pixel.

| Title |
Severe Storms Trigger Floods in Bangladesh |
| Description |
A series of intense storms have given rise to severe floods in northeastern Bangladesh. By April 20, more than half a million people had been evacuated, and 12 had died in the floods. Bangladesh frequently experiences severe storms during the hot season, and April 2004 has delivered a series of disasters. On April 9 and 10, a strong wind storm took 14 lives and injured nearly 200 when it swept across the country. A few days later, on April 14, two powerful tornadoes flattened over 20 villages in northern Bangladesh, killing at least 76 and injuring over 3,000. Then, on April 19, a severe storm boasting winds of 150 kilometers per hour (93 mph) moved across northeastern Bangladesh, triggering the floods shown in this false-color Moderate Resolution Imaging Spectroradiometer [ http://modis.gsfc.nasa.gov ] (MODIS) image taken on April 22, by the Terra [ http://terra.nasa.gov/ ] satellite. Several rivers across the region had swollen past flood stage. Shown here are the Meghna, right, and its flooded tributaries, and the Jamuna, left. Water also flowed down from the Khasi Hills along the border with India. The hills line the top of the flood region in this image. In these images, vegetation is bright green, water is dark blue, and clouds are light blue. The high resolution images provided above are at MODIS? maximum resolution of 250 meters per pixel. Part of the reason the storms caused so much destruction is the sheer number of people in the country. With well over 900 people per square kilometer, Bangladesh is one of the most densely populated countries in the world.

Fires in South Asia
| Title |
Fires in South Asia |
| Description |
Widespread agricultural (slash-and-burn) fires across northeastern India and Myanmar on the afternoon of March 20, 2006, left a shroud of smoke hanging over the landscape the following morning. These images of the area were captured by the Moderate Resolution Imaging Spectroradiometer (MODIS) [ http://modis.gsfc.nasa.gov ] on NASA's Terra [ http://terra.nasa.gov ] (March 21) and Aqua [ http://aqua.nasa.gov ] (March 20) satellites. Fires have been burning throughout the region since February, as people prepare for spring planting. While these fires are not necessarily immediately hazardous, such widespread burning can have a strong impact on air quality and human health, natural resources, and climate. The high-resolution image provided above has a spatial resolution of 500 meters per pixel. The MODIS Rapid Response System provides daily images [ http://rapidfire.sci.gsfc.nasa.gov/subsets/?FAS_Bangladesh ] of this area in a variety of resolutions and formats.

Smog over the Bay of Bengal |
| Description |
Against the arcing backdrop of the Himalaya Mountains (top of image), rivers of grayish haze follow the courses of the Ganges River and its tributaries (left) and the Brahmaputra River (right) on February 1, 2006. The plumes appear to combine like their watery counterparts and flow out together over the Bay of Bengal past the Mouths of the Ganges, the multi-pronged delta of the river along the Bangladesh coast. This image was captured by the Moderate Resolution Imaging Spectroradiometer (MODIS) [ http://modis.gsfc.nasa.gov ] on NASA's Terra [ http://terra.nasa.gov ] satellite. Scientists studying the cloud of haze that frequently lingers over parts of Asia from Pakistan to China and even the Indian and Pacific Oceans have called the pollution the "Asian Brown Cloud." The mix of aerosols (tiny particles suspended in the air) includes smoke from agricultural and home heating and cooking fires, vehicle exhaust, and industrial emissions. In addition to the respiratory problems the persistent haze can cause, it also appears to hinder crops by blocking sunlight and could be altering regional weather.

Southern Asia Heat Wave |
| Description |
A pre-monsoon heat wave left India, Pakistan, Nepal, and Bangladesh baking for much of June 2005. The heat wave, which started at the end of May, has claimed more than 200 lives in India alone, according to news reports, and has also caused deaths in Pakistan, Bangladesh, and Nepal. The top surface temperature image, created from data gathered by the Moderate Resolution Imaging Spectroradiometer (MODIS [ http://modis.gsfc.nasa.gov ]) on NASA?s Terra [ http://terra.nasa.gov/ ] satellite between May 25 and June 1, 2005, shows the start of the heat wave. Compared to images collected during the same time in 2004, there is less gradation between the hot plateaus of south Asia and the frigid peaks of the Himalaya. In 2005, searing heat, shown in yellow, spread across India?s northern plains and along the southern base of the Himalaya in Pakistan and Nepal. In agreement with this image, temperatures stayed between 40 and 50 degrees Celsius (104 ? 122 degrees F) for much of June. Monsoon rains starting on June 21 brought relief to some of the region.

Thick Haze Over Northern Ind

| Title |
Thick Haze Over Northern India |
| Description |
The skies over Northern India are filled with a thick soup of aerosol particles all along the southern edge of the Himalayan Mountains, and streaming southward over Bangladesh and the Bay of Bengal. Notice that the air over the Tibetan Plateau to the north of the Himalayas is very clear, whereas the view of the land surface south of the mountains is obstructed by the brownish haze. Most of this air pollution comes from human activities. The aerosol over this region is notoriously rich in sulfates, nitrates, organic and black carbon, and fly ash. These particles not only represent a health hazard to those people living in the region, but scientists have also recently found that they can have a significant impact on the region's hydrological cycle and climate (click to read the relevant NASA press release [ http://earthobservatory.nasa.gov/Newsroom/NasaNews/2001/200108135050.html ]). This true-color image was acquired on December 4, 2001, by the Moderate-resolution Imaging Spectroradiometer (MODIS), flying aboard NASA?s Terra [ http://earthobservatory.nasa.gov/cgi-bin/redirect?http://terra.nasa.gov/ ] satellite. It is interesting to compare the image above with this earlier MODIS image over the region, acquired on October 23, 2001 [ http://earthobservatory.nasa.gov/Newsroom/NewImages/images.php3?img_id=5258 ]. Notice the difference in the clarity of the air over the region in the earlier image. Under the thick plume of aerosol, the Brahmaputra (upper right) and Ganges Rivers are still visible. The many mouths of the Ganges have turned the northern waters of the Bay of Bengal a murky brown as they empty their sediment-laden waters into the bay. Toward the upper lefthand corner of the image, there appears to be a fresh swath of snow on the ground just south of the Himalayas.

Thick Haze Over Northern India |
| Description |
The skies over Northern India are filled with a thick soup of aerosol particles all along the southern edge of the Himalayan Mountains, and streaming southward over Bangladesh and the Bay of Bengal. Notice that the air over the Tibetan Plateau to the north of the Himalayas is very clear, whereas the view of the land surface south of the mountains is obstructed by the brownish haze. Most of this air pollution comes from human activities. The aerosol over this region is notoriously rich in sulfates, nitrates, organic and black carbon, and fly ash. These particles not only represent a health hazard to those people living in the region, but scientists have also recently found that they can have a significant impact on the region's hydrological cycle and climate (click to read the relevant NASA press release [ http://earthobservatory.nasa.gov/Newsroom/NasaNews/2001/200108135050.html ]). This true-color image was acquired on January 14, 2002, by the Moderate-resolution Imaging Spectroradiometer (MODIS), flying aboard NASA?s Terra [ http://earthobservatory.nasa.gov/cgi-bin/redirect?http://terra.nasa.gov/ ] satellite.

Tropical Cyclone Sidr
| Title |
Tropical Cyclone Sidr |
| Description |
Tropical Cyclone Sidr was continuing its northward progress over the Bay of Bengal on November 14, 2007. It was moving north toward the Mouths of the Ganges at a speed of 13 kilometers per hour (8 miles per hour), and winds in the storm system were raging at 220 km/hr (140 mph) near the storm's center, making it a Category 4 strength [ http://www.nhc.noaa.gov/aboutsshs.shtml ] tropical cyclone. The Moderate Resolution Imaging Spectroradiometer (MODIS [ http://modis.gsfc.nasa.gov ]) on NASA's Terra [ http://terra.nasa.gov/ ] satellite acquired this photo-like image at 10:15 a.m. local time (4:45 UTC) on November 14, 2007. Tropical Cyclone Sidr appears here as a well-developed and distinct ball of circling clouds, the storm has a distinct but cloudy eye at its center. An extended arm of clouds reaches northward from the storm across Bangladesh, bringing the influence of the storm onshore already even though it was hundreds of kilometers to the south. Western Bangladesh, where the storm appeared to be headed as of November 15, is the most heavily populated low-lying area in the world, with a history of severe causalities from previous storms due to both direct flooding and storm surge. The Joint Typhoon Warning Center [ https://metocph.nmci.navy.mil/jtwc.php ] was predicting that the storm would weaken, but still make landfall with hurricane-force winds. In 1970, a Category 3 storm that made landfall in the same vicinity caused 300,000 deaths and was one of the most deadly natural disasters in modern history. Another 138,000 people perished in 1991 from another such cyclone.

Tropical Cyclone Sidr |
| Description |
Tropical Cyclone Sidr had been moving slowly north and gathering power as it drew closer to the coastline around the Mouth of the Ganges. However, in the hours before landfall, according to the Joint Typhoon Warning Center, [ https://metocph.nmci.navy.mil/jtwc.php ] the powerful Category 4 [ http://www.nhc.noaa.gov/aboutsshs.shtml ] cyclone lost strength and picked up its speed. As of November 16, peak winds had fallen to 110 kilometers per hour (70 miles per hour) and the storm was moving inland at 50 km/hr (30 mph). The Moderate Resolution Imaging Spectroradiometer (MODIS [ http://modis.gsfc.nasa.gov ]) on NASA's Terra [ http://terra.nasa.gov/ ] satellite acquired this photo-like image at 11:35 a.m. local time (6:05 UTC) on November 16, 2007. The storm appears to have no particular organization, dramatically different from just one day earlier, when it was an unmistakably powerful cyclone. As of November 16, sources such as the International Herald Tribune were reporting casualties from Sidr of perhaps 200 people in Bangladesh. India was largely spared from the storm. Evacuations had removed hundreds of thousands of people in both countries ahead of the storm. The storm surge and rain did flood many areas, overwhelming some protective dikes, burying fields under water, and washing away many mud homes in the coastal area. Power lines were toppled in many areas, and all of Bangladesh was without power for several hours during the height of the storm. Western Bangladesh, where the storm made landfall, is the most heavily populated low-lying area in the world, with a history of severe causalities from previous storms due to both direct flooding and storm surge. In 1970, a Category 3 storm that made landfall in the same vicinity caused 300,000 deaths and was one of the most deadly natural disasters in modern history. Another 138,000 people perished in 1991 from a similar cyclone. NASA image created by Jesse Allen, using data provided by the MODIS Rapid Response [ http://rapidfire.sci.gsfc.nasa.gov/ ] team. |

Flooding in Eastern India |
| Description |
India's annual monsoon triggered widespread flooding throughout the country in early July 2007. In West Bengal, ABC News [ http://www.abc.net.au/news/stories/2007/07/08/1972766.htm ] reported, nearly a million people were stranded by flooding. Every major river in the East Indian state was swollen from torrential rain and releases from too-full reservoirs, ABC added. As of July 10, at least 187 people had died and 7 million had been affected by flooding across India, said Reuters. [ http://www.reuters.com/article/homepageCrisis/idUSDEL267798._CH_.2400 ] This image shows extensive flooding in West Bengal (top) and northern Orissa (lower left) as seen by the Moderate Resolution Imaging Spectroradiometer (MODIS [ http://modis.gsfc.nasa.gov ]) flying on NASA's Terra [ http://terra.nasa.gov/ ] satellite on July 9, 2007. The lower image was taken on May 31, before the monsoon rains started. In this type of image, water is typically black, as seen in the Bay of Bengal. However, the water is heavily laden with mud in the flooded landscape, so its coloring is light blue. The extensive floods cut between the channels of the Ganges River, which flow into the Bay of Bengal in the center of the image, and extend southwest along the coast. Additional flooding is visible in the large image, which shows a broader area. Clouds, which appear light blue and white in this image made from infrared and visible light, cover the floods in Bangladesh to the east. In addition to causing floods, the monsoon rains have brought new life to eastern India. The landscape has gone from the tan-pink of bare earth to the bright green that indicates plant cover. You can download a 250-meter-resolution KMZ file of the flooding [ http://earthobservatory.nasa.gov/NaturalHazards/Archive/Jul2007/eindia_tmo_2007190.kmz ] and comparison imagery from May 31, suitable for use with Google Earth.

Flooding in India and Bangladesh |
| Description |
Just as the summer floods were starting to subside, September brought more rain to South Asia. The heavy monsoon rain pushed rivers in Northeast India, Nepal, and Bangladesh over their banks and forced more than a million people from their homes. These images show floods on the Sapt Kosi River in northern India. The river curves from Nepal across the Ganges Plain, where it eventually joins the Ganges River. Flowing from the Himalaya Mountains, the river is prone to flooding in the summer when snow melt combines with monsoon rains to increase the river's flow. It is one the the major tributaries of the Ganges River. The contrast between winter and spring's dry-season water levels and late-summer, rainy-season water levels is illustrated by this pair of images. The left image was taken on September 11, 2007, after several days of heavy rain. The right image is from May 22, 2007, just before the summer monsoon started. In September, the river was several kilometers wider than it had been in late May. The water is light blue, an indication that it is muddy. Though the river was widest in India, it was also swollen in Nepal. In the days that preceded September 11, heavy rains triggered floods and landslides along rivers throughout Nepal, leaving at least 15 dead, reported the Agence France-Presse [ http://www.reliefweb.int/rw/rwb.nsf/db900sid/SODA-76W4RF?OpenDocument&rc=3&emid=FL-2007-000129-PAK ] on September 9. Along the bottom of the image, the Ganges River was also fuller than it had been earlier in the year. Additional flooding on the Ganges and its tributaries can be seen in the large images, which show a wider view of the Ganges Plain. The images were both captured by the Moderate Resolution Imaging Spectroradiometer (MODIS [ http://modis.gsfc.nasa.gov ]) on NASA's Terra [ http://terra.nasa.gov/ ] satellite and were made with a combination of infrared and visible light to increase the contrast between water and land. In this type of image, water is black, though sediment can color the water blue. Plant-covered land is bright green, and bare earth or sparsely vegetated land is tan. Clouds are light blue and white. A photo-like [ http://rapidfire.sci.gsfc.nasa.gov/subsets/?FAS_India3/2007254 ] version of the images is available from the MODIS Rapid Response System, which provides daily images of northern India.

The summer flood season was coming to an end, and rivers were subsiding when late-season monsoon rain triggered a fresh round of flooding in early September 2007. Water levels on the Brahmaputra and the Ganges Rivers simultaneously rose to dangerous levels displacing more than a million people in India and Bangladesh, reported Agence France-Presse and the BBC. This pair of images, collected by the Moderate Resolution Imaging Spectroradiometer (MODIS [ http://modis.gsfc.nasa.gov ]) on NASA's Aqua [ http://aqua.nasa.gov/ ] and Terra [ http://terra.nasa.gov/ ] satellites, compares September's flood with the earlier summer flood. To compare these flood scenes to conditions during the dry season, see Floods in Bangladesh. [ http://earthobservatory.nasa.gov/NaturalHazards/natural_hazards_v2.php3?img_id=14430 ] Water in these images is blue or black, vegetation is green, and clouds are turquoise and white. The Ganges River and its tributaries, particularly the Sapt Kosi and the Mahananda, were larger on September 10, top, than they had been at the height of the previous summer floods just one month earlier. The most significant flooding, however, was on the Brahmaputra River. In August, the braided channels of the river were still visible despite the floods. By September, the river was so swollen that none of its usual structure was visible. The water was also lighter in color, an indication that it carried more sediment than it did previously.

Floods in Bangladesh |
| Description |
Flash floods poured over the Khasi Hills after heavy unseasonal rains fell in Bangladesh starting on May 24, 2005. Located along Bangladesh?s northeast border with India, the hill region is particularly prone to flooding during the summer monsoon, but these rains and floods came early. On May 27, 2005, when the Moderate Resolution Imaging Spectroradiometer (MODIS [ http://modis.gsfc.nasa.gov ]) on NASA?s Terra [ http://terra.nasa.gov/ ] satellite captured the top image, most of the northeast corner of Bangladesh was covered with dark blue flood water. To the east, rivers in India are also swollen. According to news reports, 100,000 people have been affected by the floods, and 10 have died. The lower MODIS image, taken on May 12, 2005, by the Terra satellite, shows the region under normal dry season conditions. Both images are shown in false color so that water is dark blue or black, clouds are light blue and white, and vegetation is bright green. The large images provided above have a resolution of 250 meters per pixel. The MODIS Rapid Response Team provides daily images [ http://rapidfire.sci.gsfc.nasa.gov/subsets/?FAS_Bangladesh/ ] of this region in a variety of resolutions.

Floods in Bangladesh |
| Description |
Dozens of villages were inundated when rain pushed the rivers of northwestern Bangladesh over their banks in early October 2005. The Moderate Resolution Imaging Spectroradiometer (MODIS [ http://modis.gsfc.nasa.gov ]) on NASA's Terra [ http://terra.nasa.gov/ ] satellite captured the top image of the flooded Ghaghat and Atrai Rivers on October 12, 2005. The deep blue of the rivers is spread across the countryside in the flood image, and a few clouds—light blue and white in this false-color treatment—cover the region. Low-lying Bangladesh floods often. The country is built over the flood plains of three major rivers, the Brahmaputra, Meghna, and Ganges Rivers. The three rivers converge in Bangladesh and empty into the Bay of Bengal through the largest river delta in the world. The flat land within each flood plain is fertile, and the country is densely populated. As a result, floods on any of the three rivers can affect a vast number of people. When all of the rivers run high with monsoon rains and melting snow from the Himalaya Mountains (the source of the rivers), much of Bangladesh can be under water.

By June 20, 2007, the summer's first floods had engulfed northeastern Bangladesh. Monsoon rains routinely flood the low-lying country in the summer, though some years are worse than others. This image, captured by the Moderate Resolution Imaging Spectroradiometer (MODIS [ http://modis.gsfc.nasa.gov ]) on NASA's Aqua [ http://aqua.nasa.gov/ ] satellite, is centered on the northeast administrative region, Sylhet. Water, dark blue and black in the false-color image, covers most of the region. The floods destroyed several villages, trapped thousands of families, and forced thousands of evacuations, reported the Gulf Times on June 20. Officials were expecting the floods to worsen as monsoon rains continue to fall. The lower image, captured by Terra MODIS, shows Bangladesh on May 1, before the monsoon started. Even during the dry season, the region is spotted with dark pools of water, an indication that the land may be marshy year-round. Both images were made with a combination of infrared and visible light to increase the contrast between water and earth. Plant-covered land is bright green, bare earth is tan, and clouds are light blue and white. The Bangladeshi capital, Dhaka, is a concentrated area of gray in the lower left corner of the image.Daily images [ http://rapidfire.sci.gsfc.nasa.gov/subsets/?FAS_Bangladesh ] of Bangladesh are available from the MODIS Rapid Response System in both false color, as shown here, and photo-like true color.

*Floods In Bangladesh and India* For the past two weeks floods have ravaged eastern India and northern Bangladesh, killing over 50 people and displacing hundreds of thousands from their homes. This false-color image acquired on July 16, 2002, by the Moderate Resolution Imaging Spectroradiometer (MODIS) aboard NASA?s Terra spacecraft shows some of the worst flooding. The dark brown swollen river at the top of the image is the Brahmaputra River, which flows through the middle of the Indian state of Assam. Normally, the river and its tributaries would resemble a tangle of thin lines. Cloud cover obstructs additonal flooding in northern Bangladesh. In this false-color image, land is tan, and clouds are pink and white. Water comes across as black or dark brown. Image courtesy Jacques Descloitres, MODIS Land Rapid Response Team at NASA GSFC. |

Floods In Bangladesh and India |
| Description |
*Floods In Bangladesh and India* For the past month heavy monsoon rains have led to massive flooding in eastern India, Nepal, and Bangladesh, which have killed over 500 people and left millions homeless. This false-color image acquired on August 5, 2002, by the Moderate Resolution Imaging Spectroradiometer (MODIS) aboard NASA?s Terra spacecraft shows the extent of this flooding. In the upper right-hand corner of the image, the swollen Brahmaputra River runs east to west through the Indian state of Assam. Normally, the river and its tributaries would resemble a tangle of thin lines. Moving to the upper left-hand corner, flooding can be seen along the Ganges River in the state of Bihar, India. Both of these rivers flow into Bangladesh along with many others from India and Nepal. Heavy monsoon rains from all across the region have inundated the small country with water this year. Floodwaters have all but covered northeastern Bangladesh, which is usually dry. The Jamuna River, which runs down the center of the country off of the Brahmaputra River, now resembles a narrow lake. Millions of dollars in crops have been destroyed and thousands have been left stranded in their villages or on rafts. Forecasters are warning that flooding could get worse. In this false-color image, land is green, and water is black and dark brown. Clouds appear pink, red and white. Image courtesy Jacques Descloitres, MODIS Land Rapid Response Team at NASA GSFC. |
