Biomass Burning in Southeast Asia |
| Description |
Dozens of fires (red pixels) were burning in Vietnam, Laos, and Cambodia on April 2, 2002. There was a particularly large fire just southwest of Ho Chi Minh City near the southernmost tip of Vietnam. Note the large, grey smoke plume blowing westward in this scene. This image was acquired by the Moderate-resolution Imaging Spectroradiometer [ http://modarch.gsfc.nasa.gov/ ] (MODIS), flying aboard NASA?s Terra [ http://terra.nasa.gov/ ] satellite. Please note that the high-resolution scene provided here is 500 meters per pixel.

Drought in Southeast Asia
| Title |
Drought in Southeast Asia |
| Description |
Southeast Asia?s rainy season came to an early end in October 2004, and since that time, little rain has fallen on the Indochina Peninsula and parts of southern China. The dry spell has launched the region into the worst drought it has seen in years, with wells and reservoirs drying, crops withering, and, for some, food shortages. The effects of the drought are clearly visible in this image, generated from data 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 between February 18 and March 5, 2005. The image shows vegetation anomaly, a measure of plant density and health over a wide area. To determine the state of vegetation this year, the data are compared to the average of vegetation measurements collected during the same period in 2000 to 2004. Regions that are drier, where plants are less dense and healthy than normal, are brown, while areas with denser-than-average vegetation are green. In the latter half of February 2005, Southeast Asia was very dry, with plants showing clear signs of drought stress. Clouds, masked out in grey, covered much of southern China, central Vietnam, Laos, and parts of Thailand and Cambodia during this two-week period. NASA image created by Jesse Allen, Earth Observatory, using data provided by the joint Global Agricultural Monitoring Project between NASA, USDA?s Foreign Agricultural Service (FAS), and the University of Maryland. More data and information about this joint project is available at Satellite Information for Agricultural Monitoring [ http://tripwire.geog.umd.edu/usda/ ]. |

Fires in Southeast Asia
| Title |
Fires in Southeast Asia |
| Description |
The widespread and intense biomass burning ocurring throughout southeast Asia is producing high concentrations of carbon monoxide (CO), as shown in this image of observations by the Measurements of Pollution in The Troposphere (MOPITT) instrument on NASA's Terra satellite. This false-color image shows the mixing ratios of CO at an altitude of about 3 km (700 hPa) averaged from April 3-13, 2003. Gray areas indicate where no data are available, either due to cloud cover or the surface elevation being higher than 3 km (such as over the Himalayas). The highest mixing ratios are seen over Myanmar, southern China, Vietnam, Laos, and Thailand. Carbon monoxide levels as high as 330 parts per billion by volume of air (red pixels) were measured. The pollution is seen being carried out over the Gulf of Tonking and the Island of Hainan. Images from the MODIS instruments on Terra and Aqua show the locations of the numerous fires across the region and the thick, widespread pall of smoke they have been produced on April 3 [ http://earthobservatory.nasa.gov/NaturalHazards/natural_hazards_v2.php3?img_id=10133 ] and April 11 [ http://earthobservatory.nasa.gov/NaturalHazards/natural_hazards_v2.php3?img_id=10157 ].

| Description |
On April 8, 2003, the Moderate Resolution Imaging Spectroradiometer (MODIS) on the Aqua satellite captured this image of intense biomass burning across Southeast Asia. At left, Bangladesh is free of fires, while to the east, eastern India is covered by red dots indicating active fires. Fires are widespread across Myanmar (center), and (top right to bottom) China, Vietnam, Laos, and Thailand. A grayish pall of smoke hangs over most of the area. In the center of the visible portion of Laos, smoke is especially thick. Compare this to a Terra image acquired earlier in the day. 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 Jeff Schmaltz, MODIS Rapid Response Team, NASA GSFC |

Fires in Southeast Asia |
| Description |
The Moderate Resolution Imaging Spectroradiometers (MODIS) on NASA?s Terra and Aqua satellites have been monitoring biomass burning activity in Southeast Asia as the season got underway more than a month ago. Up until now, fire activity has been concentrated in Myanmar and countries to the east, including Thailand and Laos. In this image from Aqua MODIS on March 16, 2004, fire activity is concentrated in southern India (center) and western Myanmar (right). Scores of fires were detected by MODIS and are marked in red. The densest cluster of fires is producing thick smoke. At this time of year, many fires are being set intentionally for agricultural purposes. Though not necessarily immediately hazardous, such large-scale burning can have a strong impact on weather, climate, human health, and natural resources. The high-resolution image provided above is 500 meters per pixel. The MODIS Rapid Response System provides this image at additional resolutions.

Fires in Southeast Asia |
| Description |
Across Southeast Asia, the biomass burning season is in high gear in mid-March 2004. This is the time of year for agricultural burning?clearing farmland and renewing farmland and rangeland to prepare for the coming spring growing season. In this Moderate Resolution Imaging Spectroradiometer (MODIS) image from March 15, 2004, scores of fires were detected by the sensor during aTerra satellite overpass, and they are marked with red dots. A thick blanket of blue-gray smoke hangs over the right half of the image, shrouding Cambodia (bottom right), Thailand, (to the northwest), Laos (northeast of Thailand), and parts of southern China (top right) and Myanmar (to the west). The widespread nature of the fires suggests that these fires are being set intentionally for agricultural purposes. Though not necessarily immediately hazardous, such large-scale burning can have a strong impact on weather, climate, human health, and natural resources. The high-resolution image provided above is 1 kilometer per pixel. The MODIS Rapid Response System provides this image at additional resolutions.

Fires in Southeast Asia |
| Description |
Seasonal agricultural burning continued to intensify across Southeast Asia on December 26, 2004. In this image from the Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA?s Terra satellite, the locations of actively burning fires across Thailand, Cambodia, and Laos are marked with red dots. Two particularly concentrated areas of burning are visible. One is in the northern part of the broad river valley in western Thailand, at image left. The other is to the west of the Tônlé Sap (a large lake that quintuples in size during the wet phase of the monsoon) in Cambodia. The widespread nature of the fires, their location (generally located away from remaining natural vegetation, which appears deeper green), and the time of year suggest that these fires are being set intentionally for agricultural purposes. Though not necessarily immediately hazardous, such large-scale burning can have a strong impact on weather, climate, human health, and natural resources.

Fires in Southeast Asia |
| Description |
Dense smoke lingers over Southeast Asia in this Moderate Resolution Imaging Spectroradiometer (MODIS [ http://modis.gsfc.nasa.gov ]) image, collected on March 30, 2005, by NASA's Terra [ http://terra.nasa.gov/ ] satellite. It is currently the dry season, a time when fire is common in Southeast Asia. Though several fires, marked with red dots, were detected when Terra flew over in the morning, the majority of the smoke was probably generated the previous day. During the day, hundreds of fires are set, so that by the time the MODIS sensor on NASA's Aqua satellite flew over in the early afternoon [ http://earthobservatory.nasa.gov/NaturalHazards/natural_hazards_v2.php3?img_id=12798 ] on March 30, the landscape was covered with fire. In 2005, severe drought dried the vegetation throughout Southeast Asia, making the region more prone to fire. The effect of the widespread fires on air quality is clearly visible in this image. The heavy grey smoke settles in the valleys of northern Laos and Thailand, and blankets sections of Myanmar and Vietnam. NASA image created by Jesse Allen, Earth Observatory, using data obtained from the Goddard Earth Sciences DAAC. |

Fires in Southeast Asia |
| Description |
Biomass burning in Southeast Asia peaks in late winter or early spring as farmers begin to prepare land for seasonal planting. The widespread nature of the burning creates a seasonal pattern of emissions that play a significant role in regional air pollution, including tropospheric ozone. (Ozone can be both beneficial and harmful in the atmosphere, depending on its altitude. High up in the stratosphere, ozone protects the planet from harmful UV radiation. Closer to earth, tropospheric ozone is a harmful air pollutant.) Like most parts of the world, the burning in Southeast Asia exhibits a diurnal (daily) cycle, in which burning is less widespread in the morning and increases throughout the day. Compare this morning image of Southeast Asia, including (left to right) Thailand, Cambodia, Laos, and Vietnam, captured by the Moderate Resolution Imaging Spectroradiometer (MODIS) on the Terra satellite to the same area captured by Aqua MODIS in the afternoon. Note the dramatic increase in fires (red dots) in the afternoon image. This image was acquired Jan. 31, 2003. 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 Jeff Schmaltz, MODIS Rapid Response Team, NASA GSFC |

Fires in Southeast Asia
| Title |
Fires in Southeast Asia |
| Description |
Wildfires and agricultural fires are widespread in the southeast Asian countries of Thailand, Laos, and Cambodia from February to April each year, and have been responsible for severe deforestation in the region. The impact of these intense local pollution sources on regional air quality can be monitored from space using satellite remote sensing. This false-color image shows carbon monoxide plumes at an altitude of roughly 3 km (700 millibars) in the atmosphere over southeast Asia. This image represents a composite of data collected from February 20-25, 2003, by the Measurements Of Pollution In The Troposphere (MOPITT) instrument aboard NASA?s Terra satellite. The gray areas show where no data were collected, either due to persistent cloud cover or gaps between viewing swaths. Carbon monoxide is a good tracer of pollution since it is produced as a by-product of the combustion associated with biomass burning. The regions of high carbon monoxide correlate well with earlier observations of the source fires made by the Moderate Resolution Imaging Spectroradiometer (MODIS).
