Fires on Borneo and Sumatra
In Sumatra and Indonesia, seasonal fires and the thick smoke they produce plagued the islands for nearly two months in late 2006. Beginning in mid-September 2006, the Moderate Resolution Imaging Spectroradiometer (MODIS) on NASAs Aqua satellite detected numerous fires in daily images of the area. This image was captured by Aqua MODIS on 9 November 2006. Active fire locations are marked with red dots. Thick smoke spreads between the two islands, the grayish haze mingling with brighter clouds.

Many factors contribute to the fires, which usually start from agricultural burning, but often spread into adjacent tropical forest. When the forests have been degraded by logging, they become much more prone to fire. In addition, climate fluctuations, such as droughts that occur in concert with El Niño events, can make the fires worse. During droughts, the typically soggy forest floor of these lowland forests dries out. The thick layer of dead vegetation on the forest floor, peat, becomes flammable and produces enormous quantities of smoke when it burns.

II. Fire Weather and Fire Danger Monitoring and Early Warning
Regional Fire Weather
The Regional South East Asia Fire Danger Rating System (SEA FDRS) is a joint effort between the Canadian Forest Service (CFS) and the Malaysian Meteorological Service (MMS), supported by the Canadian International Development Agency (CIDA). Daily updated SEA Fire Danger Rating can be downloaded on the following website of MMS, and background information on the project can be found at the SEA FDRS Project website.
Latest example of a SEA FDRS product:
The Fire Weather Index (FWI) values shown on the map are numerical ratings of fire intensity.
Information from the Initial Spread Index (ISI) and Build Up Index (BUI) is combined to provide a numerical rating of fire intensity.
This index is used to indicate the difficulty of fire control based on the head fire intensity and fire fighting capability.
Information on the Indonesian Fire Danger Rating System (Indonesian FDRS) is provided by the Indonesian Bureau of Meteorology and Geophysics (BMG) in Jakarta. The site provides information for fire managers working to prevent and control vegetation fires and smoke in Indonesia. This link points to the English version; a Bahasa Indonesian version can be found there as well: http://www.bmg.go.id:8080/fdrs/index_e.html.
The GFMC displays selected and daily updated global and Asia-Pacific Experimental Climate Prediction Center (ECPC) Fire Weather Forecasts. These examples allow a quicklook and provide daily and weekly total forecasts and forecasted monthly totals. For background information refer to the ECPC products description page.
