Floods in Myanmar
| Title |
Floods in Myanmar |
| Description |
With the onset of monsoon rains, the Ayeyarwady River of Myanmar (Burma) more than doubled in size during June. 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 June 21, 2006, nearly one month after the lower image was taken on May 22. By June 21, the winding shape of the river is concealed by the monsoon floods. In the large image, similar flooding is visible farther north. To the left of the river, flood water drenches the ground. The region around this stretch of the river is wetland, and the image may be showing normal rainy-season conditions for the wetland. These images are shown in MODIS' shortwave and near-infrared bands to highlight the presence of water. Clear water is dark blue or black, while sediment-laden water is lighter blue. Clouds are pale blue and white, plant-covered land is green, and bare earth is tan. The large images provided above have a resolution (level of detail) of 250 meters per pixel. Daily images [ http://rapidfire.sci.gsfc.nasa.gov/subsets/?FAS_Bangladesh/2006172 ] of the region are available from the MODIS Rapid Response Team in a variety of resolutions.

Monsoon Floods in India
| Title |
Monsoon Floods in India |
| Description |
June normally marks the beginning of the monsoon season in India, but early rains triggered floods in northeastern India earlier than normal. According to news reports, 25,000 people were displaced in India's Assam state when the Brahmaputra River burst its banks in early June. 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 June 3, 2006, the river was already swollen with a week's worth of monsoon rains. To the south of the river, water puddles in low-lying regions and runs in streaks down the Khasi Hills near the border with Bangladesh. Additional flooding may be occurring in Bangladesh, but the Sun's reflection masks the surface in a silvery mirror called sunglint. Clouds, light blue and white in these images, also hide some of the floods from view. The lower image shows Assam, India, and eastern Bangladesh a little over a week earlier, before the monsoon rains set in. The river is dry-season thin as it snakes through its bed, which is tan from being scoured of most or all plants during the seasonal floods. Red dots along the river show where MODIS detected several fires. The large images provided above have a resolution of 500 meters per pixel. Daily images [ http://rapidfire.sci.gsfc.nasa.gov/subsets/?FAS_Bangladesh/2006154 ] of eastern India and Bangladesh are available from the MODIS Rapid Response Team in a variety of resolutions, including MODIS' maximum resolution of 250 meters per pixel.

Monsoon Floods in Northern I
| Title |
Monsoon Floods in Northern India |
| Description |
The combined impact of a tropical cyclone and monsoon rains drove the many branches of the Ganges River in the Sundarbans delta of eastern India over their banks in late September 2006. The most notably flooded river in the top Moderate Resolution Imaging Spectroradiometer (MODIS [ http://modis.gsfc.nasa.gov ]) image, collected by NASA's Aqua [ http://aqua.nasa.gov/ ] satellite on September 26, is the Hugli River, which has spread several kilometers over its flood plain compared to conditions nine days earlier (lower image). The Hugli River [ http://earthobservatory.nasa.gov/Newsroom/NewImages/images.php3?img_id=17410 ] (also Hooghly) branches off the Ganges about 200 kilometers north of Kolkata (Calcutta) and flows south past the city through the state of West Bengal to drain into the Bay of Bengal. Though the city of Kolkata is obscured by clouds in the flood scene (it's the tan region near the bottom of the lower image), the Australian Broadcasting Corporation reported that floods in the city forced more than 2,000 people from their homes. The cloud-free region around the city reveals extensive flooding, with water forming black or dark blue streaks and pools on the bright green, vegetated land. Additional flooding is visible along the Hugli and other branches of the Ganges in the large image. These images were created using both visible and infrared light to allow water to stand out from the land. In these images, clouds are pale blue and white, water is dark blue or black, plant-covered land is green, and bare or sparsely vegetated land (like the city) is tan. Additional infrared images [ http://rapidfire.sci.gsfc.nasa.gov/subsets/?FAS_Bangladesh/2006269 ] and photo-like images of India are available from the |

Fires in South Asia
| Title |
Fires in South Asia |
| Description |
The skies were hazy over Bangladesh, northeastern India, and Myanmar on March 8, 2006, as the smoke from hundreds of fires rose into the air. The Moderate Resolution Imaging Spectroradiometer (MODIS) [ http://modis.gsfc.nasa.gov ] on NASA's Aqua [ http://aqua.nasa.gov ] detected fires (marked in red) in high concentrations in northeast India to the south of the Brahmaputra River (tan ribbon cutting across the upper left corner) as well as in the hilly terrain at the border of India and Myanmar.

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 Northern India
| Title |
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 ].

Floods in Bangladesh
| Title |
Floods in Bangladesh |
| Description |
Northeastern Bangladesh disappeared under monsoon floods as rains drenched the region in June 2006. By June 21, 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, the floods stretched across hundreds of kilometers of what had been dry land a month earlier. According to Reuters, [ http://www.alertnet.org/thenews/newsdesk/DHA197717.htm ] the floods claimed nine lives, made 10,000 homeless, and marooned more than a million by June 18. The monsoon rains typically last from June to September. These satellite images of the floods combine MODIS' observations of shortwave and near-infrared wavelengths of light with visible light to allow water to stand out against the land. Water is black and dark blue. Plant-covered land is green, and clouds are pale blue and white. The MODIS Rapid Response Team provides daily images [ http://rapidfire.sci.gsfc.nasa.gov/subsets/?FAS_Bangladesh/2006172 ] of Bangladesh in both infrared and photo-like natural color.
