Review
Apart from brief periods of dry weather, the Southwest monsoon season in the region has been mostly wet up to third week of June 2001. However, weather conditions have become drier towards the end of June 2001 and into the first 3 days of July 2001. Consequently, hotspots counts over Sumatra and Kalimantan in May and June 2001 have been low with a large number of days with few or no hotspots detected. However, since the 1st July 2001, the number of hotspots has increased significantly from 81 to 154 on 2 July 2001 over Sumatra and from 14 to 77 over Borneo.

Fires burning in Malaysia and Indonesia, MODIS satellite image, 9 July 2001

Official NASA comment to this MODIS image: “A number of island nations in the eastern Indian Ocean were shrouded in thick haze produced by a large number of fires burning in Malaysia and Indonesia last week (July 8-14, 2001). Hundreds more fires were being set even as the thick cloud of smoke already severely reduced visibility across the region. Officials warned that the level of pollution was getting dangerously high and unhealthy. The fires are being set primarily by plantation owners, taking advantage of the current dry season, to clear forested lands and to burn away the surface peat in swamp areas.
The pall of haze reaches as far north as Thailand on Asia’s mainland, stretches southward over the cities of Kuala Lumpur and Singapore, and spans across the Indonesian islands of Sumatra and Borneo from west to east. Visibility was reduced to about 500 m (1,640 feet) in some of the hardest hit areas, as school children were sent home and told not to play outside, and many who work outside must wear masks to protect them from the smoke.
This true-color image shows the portion of Malaysia located on the mainland Asian peninsula (upper right), and part of the Indonesian island of Sumatra to the west and south. Kuala Lumpur, the capital of Malaysia, is visible as the greyish-brown region on the western shore of the peninsula, while Singapore sits on the peninsula’s southern tip (mostly hidden by clouds in this scene). Red pixels show the locations of many fires and dark grey pixels show the smoke and haze resulting from the flames. The bright white wisps toward the upper lefthand corner of the image are clouds.
This image was acquired by the Moderate-resolution Imaging Spectroradiometer (MODIS), flying aboard NASA’s Terra satellite, on July 9, 2001.” Source and copyright: NASA Earth Observatory.
