Floods in India and Banglade
| Title |
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.

Haze and Sediment in Banglad
| Title |
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.

Monsoon Flooding in India
| Title |
Monsoon Flooding in India |
| Description |
The Ganga (Ganges) River and its tributaries were swollen with late monsoon rains 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 on October 1, 2005. Torrential rains pounded northern India and Nepal through much of the second half of September 2005. The subsequent floods and landslides killed dozens in the two countries combined. These two images show the progression of the floods through northern India. Though severe flooding occurred in Nepal, it is not visible in these images. The lower image shows the rivers on September 20, four days after the floods began. In the false-color images, water is dark blue, clouds are pale blue, and vegetation is bright green. On September 20, the upper reaches of the Ganga and Ramganga Rivers are flooded compared to their state on October 1. By October 1, the flood water had moved downstream, gathering at the convergence of the two rivers. The Sarda and Ghagra Rivers are also larger than they were ten days earlier.

Monsoon Floods in Northern I
| Title |
Monsoon Floods in Northern India |
| Description |
Within a single week, several major rivers in India's northern Bihar state burst their banks under the onslaught of additional heavy rain. Rivers flowing out of the Himalaya Mountains in Nepal along the top of the image had expanded to such a degree by September 27, 2006, that it's difficult to distinguish one from another in the top Moderate Resolution Imaging Spectroradiometer (MODIS [ http://modis.gsfc.nasa.gov ]) image. Already running high on September 20, when the lower image was taken, the Bagmati, Lakhandai, Sapt Kosi, and their tributaries are particularly flooded. The rivers flow south through Bihar and empty into the Ganges, the lower branches of which appeared flooded in an adjacent image. [ http://earthobservatory.nasa.gov/NaturalHazards/natural_hazards_v2.php3?img_id=13897 ] The southern tributaries of the Ganges shared a similar fate: The rivers form a large pool where they run parallel to the Ganges' southern bank along the bottom of the image. A Reuters report [ http://in.today.reuters.com/news/newsArticle.aspx?type=topNews&storyID=2006-09-27T175650Z_01_NOOTR_RTRJONC_0_India-269576-1.xml ] issued on September 27 said that floods had killed 23 people in Bihar since September 20, and tens of thousands of additional people were homeless or stranded. Both images shown here were created from both visible and infrared light. This combination makes water, which might otherwise blend in with the landscape, appear dark blue or black, while the surrounding plant-covered land is bright green. Because they increase the contrast between water and land, the infrared and visible images are useful for tracking floods. Clouds are light blue and white, while non-vegetated land is tan. The top image was made with data collected by the MODIS sensor on NASA's Terra [ http://terra.nasa.gov/ ] satellite on the morning of September 27, while the lower image was made with data collected by the MODIS sensor on NASA's Aqua [ http://aqua.nasa.gov/ ] satellite on the afternoon of September 20, 2006.

Southern Asia Heat Wave
| Title |
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.

Flooding in India and Bangla
| Title |
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.

Floods In Bangladesh and Ind
| Title |
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. |

| Title |
Roof of the World and the Abode of Snow |
| Original Caption Released with Image |
The Tibetan Plateau and a portion of the Himalayan Mountain chain are captured in this MISR stereo image from May 14, 2000 (Terra orbit 2153). The image is a composite of data from the instrument's vertical and 46-degree forward cameras, and has been oriented with north at the left. Viewing the image in 3-D requires the use of red/blue glasses with the red filter placed over your left eye. On the left side of this image is the Tibetan Plateau, the highest plateau on Earth and often called the "Roof of the World." Near the lower left is lake Paiku Co, at an altitude of 4591 meters. The border between Tibet and Nepal marks the eastern extent of the magnificent Himalayan Mountains, home to many of the world's highest peaks. Himalaya is a Sanskrit word meaning "the Abode of Snow." Mt. Everest (8848 meters) and Mt. Makalu (8481 meters) are visible near the top center of the image. Further to the south is the Mahabharat Range, separated from the Himalayas by the "River of Gold", the Sun Kosi. Rounding out our tour from north to south, on the righthand side of the image, is the densely populated Indo-Gangetic Plain of northern India. MISR was built and is managed by NASA's Jet Propulsion Laboratory, Pasadena, CA, for NASA's Office of Earth Science, Washington, DC. The Terra satellite is managed by NASA's Goddard Space Flight Center, Greenbelt, MD. JPL is a division of the California Institute of Technology. |

Aerosols over India

Multi-angle Imaging SpectroR
| Title |
Aerosols over India |
| Original Caption Released with Image |
Large abundances of aerosols, or airborne particulates, over the low-lying plains of northeastern India appear in dramatic contrast with the relatively pristine air of the high-altitude Tibetan Plateau. This contrast is illustrated in these Multi-angle Imaging SpectroRadiometer images from October 15, 2001. The aerosols that contribute to poor air quality over much of the Indian subcontinent are believed to originate from industrial smoke, vehicle emissions, and biomass burning. The two images at left show the scene from MISR's 26-degree and 70-degree forward viewing angles, respectively. The high levels of aerosols are accentuated in the 70-degree forward image, due to the longer atmospheric path length associated with the more oblique viewing angle. The abundance of aerosols is derived from the variation of scene brightness and contrast as a function of observation angle, and is displayed in the third panel from the left as optical depth. This quantity is logarithmically related to the atmosphere's ability to transmit light, and is one of several variables used to characterize the climatic and environmental influence of aerosols. Areas where retrievals were not obtained, such as the topographically complex Himalayas in Nepal, and cloudy or very turbid areas, are shown in dark gray. Surface calculations for the 26-degree view direction are shown in the rightmost panel. These calculations use the optical depth field to estimate surface reflectances as if the intervening atmosphere were not present. Making corrections for atmospheric scattering is important when using reflectances measured from space in surface classification and physical process studies. Note that the algorithms used to produce these results are still being refined, and future product versions may show some differences from the preliminary values displayed here. These data were obtained during Terra orbit 9711, and represent an area of about 400 kilometers x 1600 kilometers. MISR was built and is managed by NASA's Jet Propulsion Laboratory, Pasadena, CA, for NASA's Office of Earth Science, Washington, DC. The Terra satellite is managed by NASA's Goddard Space Flight Center, Greenbelt, MD. JPL is a division of the California Institute of Technology.
