| Title |
Air Quality Emergency in Malaysia |
| Description |
In mid-August, several locations in mainland Malaysia declared air quality emergencies, as smoke from burning in Indonesia wafted across the Strait of Malacca and blanketed the country with haze. Many regions closed their schools and businesses, and news reports have indicated this may be the worst air quality event the country has experienced since the terrible fire season on Sumatra during the 1997-98 El Niño. This pair of images shows the region in Sumatra where many of the fires are burning (left), and the resulting smoke blanketing Malaysia (right). Although it is sometimes difficult to distinguish smoke from clouds, the infrared-enhanced view can penetrate the smoke in places. In this type of image, vegetation is bright green, clouds are white or light blue, and smoke becomes almost transparent in many places. Water is dark blue (nearly black). Actively burning fires are marked with red dots. These images were captured by the Moderate Resolution Imaging Spectroradiometer (MODIS) [ http://modis.gsfc.nasa.gov ] on NASA's Terra [ http://terra.nasa.gov ] satellite on August 12, 2005.

| Title |
Fires and Heavy Smoke in Sumatra |
| Description |
*Fires and Heavy Smoke in Sumatra* At least once a year for a period lasting from a week to several months, northern Sumatra is obscured by smoke and haze produced by agricultural burning and forest fires. These data products from the Multi-angle Imaging SpectroRadiometer (MISR) document the presence of airborne particulates on March 13, 2002. On the left is an image acquired by MISR?s 70-degree backward-viewing camera. On the right is a map of aerosol optical depth, a measure of the abundance of atmospheric particulates. This product utilized a test version of the MISR retrieval that incorporates an experimental set of aerosol mixtures. The haze has completely obscured northeastern Sumatra and part of the Strait of Malacca, which separates Sumatra and the Malaysian Peninsula. A northward gradient is apparent as the haze dissipates in the direction of the Malaysian landmass. Each panel covers an area of about 760 kilometers x 400 kilometers. Haze conditions had posed a health concern during late February (when schools in some parts of North Sumatra were closed), and worsened considerably in the first two weeks of March. By mid-March, local meteorology officials asked residents of North Sumatra?s provincial capital, Medan, to minimize their outdoor activities and wear protective masks. Poor visibility at Medan airport forced a passenger plane to divert to Malaysia on March 14, and visibility reportedly ranged between 100 and 600 meters in some coastal towns southeast of Medan. The number and severity of this year?s fires was exacerbated by dry weather conditions associated with the onset of a weak to moderate El Niño. The governments of Indonesia, Malaysia, and Brunei have agreed to ban open burning in plantation and forest areas. The enforcement of such fire bans, however, has proven to be an extremely challenging task.

Fires in Indonesia |
| Description |
Scores of fires were smoking across Sumatra (center) on June 8, 2003, trailing smoke across the Strait of Malacca, which separates Sumatra from Malaysia to the north, and also over the the Indian Ocean (bottom left). This image of active fire locations (red dots) was captured by the Moderate Resolution Imaging Spectroradiometer (MODIS) on the Terra satellite.

Fires on Borneo and Sumatra

Fires on Borneo and Sumatra |
| Description |
Through cloudy skies, the Moderate Resolution Imaging Spectroradiometers (MODIS) on NASA's Terra and Aqua satellites detected fires (marked in yellow) burning on the island of Borneo on August 17, 2004. The top image was captured in the afternoon (local time) and shows more fire activity than the morning image (bottom). The bulk of the island (south and central parts) is occupied by the Kalimantan region of Indonesia, while a strip across the northern part is occupied by the Sarawak region of Malaysia. Most of the fires are along the swampy western and southern coastlines of Kalimantan. Image by Jesse Allen, based on data from the MODIS Rapid Response Team, NASA-GSFC |

Fires on Sumatra
| Title |
Fires on Sumatra |
| Description |
A thick cloud of smoke pours from forest fires on the Indonesian island of Sumatra. Forest fires are common in Indonesia during the hot, dry months of the dry season, which runs from June to September. Hot, dry weather and winds blowing from the southwest help fires explode in Indonesia?s forests, and such conditions probably fed the fires seen outlined in red in this image. The winds are also responsible for blanketing parts of Malaysia with smoke. In this image, a white plume of smoke snakes north and east from the fires, moving inland over northern Malaysia. Not only does the dense haze decrease visibility, posing a traffic hazard for both air and ground travel, but the smoke could cause serious health problems. The Moderate Resolution Imaging Spectroradiometer (MODIS [ http://modis.gsfc.nasa.gov ]) onboard NASA?s Terra [ http://terra.nasa.gov/ ] satellite acquired this image in the morning of June 25, 2005. By afternoon, the fires had grown to the point that the narrow Strait of Malacca that separates Malaysia from Sumatra was barely visible. Unfortunately, clouds also partially obscured the view of the region. NASA image courtesy Jeff Schmaltz, MODIS Land Rapid Response Team [ http://rapidfire.sci.gsfc.nasa.gov ] at NASA GSFC |
