Floods in India and Bangladesh |
| Description |
Though flood waters have begun to recede in Bangladesh, much of the country remains water-logged. This Moderate Resolution Imaging Spectroradiometer [ http://modis.gsfc.nasa.gov ] (MODIS) image, taken on August 2, 2004, by the MODIS sensor on NASA's Aqua [ http://aqua.nasa.gov/ ] satellite, shows dark blue and black flood water over much of the eastern half of the country. Light blue clouds partially obscure the false-color scene where vegetation is bright green. According to the Associated Press, 586 had died in Bangladesh as a result of the floods as of August 1, bringing the toll of this year's floods to 1,551 in India, Bangladesh, Nepal, and Pakistan. Up to 30 million are homeless. The above image shows the floods at 250 meters per pixel. The image is available in additional resolutions [ http://rapidfire.sci.gsfc.nasa.gov/subsets/?FAS_Bangladesh/2004215/FAS_Bangladesh.2004215.aqua.721 ].

Fires in Eastern India
| Title |
Fires in Eastern India |
| Description |
On March 5, 2003, the Moderate Resolution Imaging Spectroradiometer (MODIS) on the Aqua satellite detected fires (marked in red) in eastern India (bottom left), northeast India (top right), and western Myanmar (bottom right). A few scattered fires were detected in Bangladesh (center). In this false-color image of this scene, dark reddish burn scars stand out against bright green vegetation. A true-color image is also available. In Bangladesh, the Ganges River flows in from the west and meets up with the Brahmaputra River flowing in from the east. The two rivers join and flow out to the Bay of Bengal through the Mouths of the Ganges. At top are the Himalaya Mountains in Nepal. The high-resolution image provided above is 500 meters per pixel. The MODIS Rapid Response System provides this image at MODIS? maximum spatial resolution of 250 meters. Image courtesy Jacques Descloitres, MODIS Rapid Response Team at NASA GSFC |

Smog over Northern India

Smog over Northern India |
| Description |
A pale band of haze hangs along the front of the Himalaya Mountains in Nepal, India, and Bangladesh in this photo-like image, taken on February 5, 2006, by the Moderate Resolution Imaging Spectroradiometer (MODIS [ http://modis.gsfc.nasa.gov ]) on NASA's Aqua [ http://aqua.nasa.gov/ ] satellite. In this image, haze covers northern India, just south of the Himalaya. Haze also intrudes into the skies of southern Nepal and Bangladesh. The skies over the more mountainous northern Nepal and Bhutan appear clear. One source of the haze is the fires that burn throughout the region. These fires were probably deliberately set for agricultural purposes. Another source of the haze is India's cities. A megacity is an urban center with 10 million or more inhabitants. As of 2003, India held three of the world's megacities: Mumbai, Delhi, and Calcutta. Moreover, smaller cities dot the landscape, appearing in this image as beige splotches. One city, shown in the upper left, produces its own discernible plume of haze. It is common to see dense haze in northern India, Nepal, and Bangladesh during the winter. The haze lingers near the base of the mountains because of a temperature inversion. In normal conditions, the air near the ground is warmer than the air above it. Warm air rises and carries with it pollution from fires or cities. The pollution disperses when it is mixed with cooler air high above the ground. During the Himalayan winter, cold air rushes down the mountains onto the plain. This makes the air near the ground cooler than the air above it, essentially trapping a pocket of cold air over the plain. Smoke from fires and regular pollution from cities are also trapped in the pocket of cold air and don't disperse as they would under normal conditions. As a result, haze builds until the inversion lifts. The haze shown in this image had been accumulating for several days, and is visible in several other MODIS images, including one acquired on February 1, 2006 [ http://earthobservatory.nasa.gov/NaturalHazards/natural_hazards_v2.php3?img_id=13341 ].

Flooding in Eastern India
| Title |
Flooding in Eastern India |
| Description |
Abutting the southern front of the snow-clad Himalaya Mountains, the broad, flat Ganges Plain is laced with rivers that transport glacial melt to the Bay of Bengal or the Arabian Sea. Not surprisingly, these rivers lead something of a Dr. Jekyll–Mr. Hyde existence: during the dry winter, the rivers are small and sedate, their headwaters largely locked in ice. In the summer, temperatures in the mountains climb, melting mountain-top snow and fueling the Asian monsoon, and the rivers swell into roaring giants. Not every year is the same however—the monsoon may be wetter in a particular year or winter snows might be greater, leading to more snowmelt—and 2007 numbered among the more extreme flood years. Heavy rain throughout July pushed the Ganges and its many tributaries over their banks, submerging large tracts of land in northeastern India. As of August 3, nearly 20 million people had been displaced in India, Bangladesh, and Nepal, and 125 had died in India, reported BBC News. [ http://news.bbc.co.uk/2/hi/south_asia/6927389.stm ] Among the most severely hit states was India's northeastern Bihar state. The Moderate Resolution Imaging Spectroradiometer (MODIS [ http://modis.gsfc.nasa.gov ]) flying on NASA's Aqua [ http://aqua.nasa.gov/ ] satellite captured the top image of flooding on the Ganges and its tributaries on August 3, 2007. The lower image, captured by Aqua MODIS on June 4, 2007, shows the plain before the summer monsoon and snowmelt swelled the rivers. In these images (made with a combination of infrared and visible light), water is black or dark blue. Water takes on a brighter shade of blue when tinged with sediment. Clouds, pale blue and white, are scattered over the flooded region, which is bright green with vegetation. Sparsely vegetated areas or bare earth in the lower image are rose-tinted tan. On August 3, the Ganges, Gandak, and Kosi Rivers were so swollen that it was hard to see exactly where the rivers normally flow. The tributaries that feed the Kosi River, not even visible on June 4, have combined in a vast web of water-covered land. The light blue area under the clouds in the lower left corner of the image is probably water-soaked earth, not standing water. Though destructive, seasonal flooding in the Ganges River system blankets the plain with fertile alluvial soil, making it productive farmland. Because the plain is so fertile, it is one of the most densely populated regions on Earth.Daily images [ http://rapidfire.sci.gsfc.nasa.gov/subsets/?FAS_India3/2007215 ] of northeastern India are available from the MODIS Rapid Response System in both false color, as shown here, and photo-like true color.

Floods in Bangladesh
| Title |
Floods in Bangladesh |
| Description |
A large portion of Bangladesh was awash with floods when the Moderate Resolution Imaging Spectroradiometer (MODIS [ http://modis.gsfc.nasa.gov ]) on NASA's Aqua [ http://aqua.nasa.gov/ ] satellite captured the top image on August 3, 2007. The low-lying nation is an alluvial delta, and therefore, is extremely prone to flooding. In July 2007, heavy monsoon rains filled the Brahmaputra, Padma, and Meghna Rivers, leading to the floods shown here. The Jamuna, a branch of the Brahmaputra River, arcs through the center of the scene, its braided waterways woven into a single thread where the river is overflowing. A branch of the Jamuna flows east into the Meghna River. The wetlands that surround these rivers are full of water, and the rivers themselves are swollen. The Padma River, formed by the convergence of the Ganges and Jamuna Rivers, is also flooded. The severity of the floods can be seen in the contrast between the top image and the lower image, which was taken on May 1, 2007, before the monsoon rains began. In the dry season, the course of each river is clearly defined, not blurred by excess water. The images were made with infrared and visible light to increase the contrast between water and earth. In this type of image, water is black or blue, where colored with sediment. Plant-covered land is bright green, and bare earth or lightly vegetated areas are tan. Light blue and white clouds dot the scene. In the lower image, red dots mark the location of fires. The floods shown here stranded hundreds of thousands of people in Bangladesh, one of the world's most densely populated nations, reported BBC News. [ http://news.bbc.co.uk/2/hi/south_asia/6927389.stm ] As of August 3, nearly 20 million people had been displaced by monsoon flooding in Bangladesh, India, and Nepal, added BBC. Some of the floods in northeastern India [ http://earthobservatory.nasa.gov/NaturalHazards/natural_hazards_v2.php3?img_id=14429 ] were visible when Aqua MODIS flew over on August 3. The intense rains of the summer monsoon typically fall between June and October, so additional flooding is likely.Daily images [ http://rapidfire.sci.gsfc.nasa.gov/subsets/?FAS_Bangladesh/2007215 ] of Bangladesh are available from the MODIS Rapid Response System in both false color, as shown here, and photo-like true color.
