Firesin Southeast Asia Wildfires and agricultural fires are widespread in the southeast Asian countriesof Thailand, Laos, and Cambodia from February to April each year, and have beenresponsible for severe deforestation in the region. The impact of these intenselocal pollution sources on regional air quality can be monitored from spaceusing satellite remote sensing. This false-color image shows carbon monoxideplumes at an altitude of roughly 3 km (700 millibars) in the atmosphere oversoutheast Asia. This image represents a composite of data collected from 20-25 February 2003, by the Measurements Of Pollution In The Troposphere (MOPITT)instrument aboard NASAs Terra satellite. The gray areas show where no datawere collected, either due to persistent cloud cover or gaps between viewingswaths. Carbon monoxide is a good tracer of pollution since it is produced as aby-product of the combustion associated with biomass burning. The regions ofhigh carbon monoxide correlate well with earlier observations of the sourcefires made by the Moderate Resolution Imaging Spectroradiometer (MODIS).
Heat signatures (red), and smoke (light blue haze) are visible from fires burning throughout South East Asia in this Moderate Resolution Imaging Spectroradiometer (MODIS) image from 24 February 2003, captured by the Aqua satellite.

The Integrated Forest Fire Management Project (IFFM) in Samarinda provides regulary updatedmaps generated by NOAA-AVHRR showing active land-use fires and wildfires inBrunei and the Indonesian and Malaysian provinces on BorneoIsland.

The Forest Fire Prevention and Control Project (FFPCP) The Forest Fire Prevention and Control Project (FFPCP) in Palembang (Sumatra) closed on 30 November 2001. The South Sumatra Forest Fire Management Project (SSFFMP) is expected to start within the second half of the year 2002 and will continue the work of FFPCP. Meanwhile the daily fire map (hot-spot) and monthly drought index for Sumatra will continue to be updated from time to time.

South East AsiaFire Monitoring by ANDES The Asia Pacific Network for Disaster Mitigation using Earth ObservationSatellite (ANDES) provides daily fire maps of mainland and insular South EastAsia. The latest maps can be accessed through the ANDESwebsite. The map below shows the latest fire map of mainland SE Asia(Thailand, Myanmar, Lao, Cambodia, Viet Nam).

The GFMC displays selected and daily updated global andAsia-Pacific ExperimentalClimate Prediction Center (ECPC) Fire Weather Forecasts.These examples allow a quicklook and provide daily and weekly total forecastsand forecasted monthly totals. For background information refer to the ECPCproducts description page.
Fire Weather Index (FWI) forecast for thisweek (left) and the predictedFWI total for next month (right) for the Western Pacific (1-3) and the PacificOcean (4-6) regions. The weekly total forecast and the monthly forecasted total refer to 00:00 hrsUTC,which is local noon at dateline (180° longitude). Forecast time is 12:00 hrsnoon UTC (Greenwich)corresponding to local evening time in mainland and insular SE Asia. (Source: ECPCFire Weather Index Forecast)
The ASEANFire Weather Information System (ASFWIS) is a co-operation betweenASEAN and the Canadian Forest Service. It provides maps describing the currentfire weather situation in South East Asia. This system is based upon theCanadian Forest Fire Danger Rating System (CFFDRS) (for further infomation tothe CFFDRS refer to ASFWIS). Studies have shown that the CFFDRS is applicableoutside of Canada. Currently it is also used in a modified form in New Zealand(see References). In NewZealand the Fire Weather Indices Fine Fuel Moisture Code (FFMC) and the InitialSpread Index (ISI) represent the fire danger in the scrublands. The DuffMoisture Code (DMC) is also applicable in South East Asia, because itpotentially describes the moisture state of the upper peat layers in peat andpeat swamp forests. All three parameters may serve as a suitable indicator offorest fire danger in South East Asia.
Haze Prevention Group The industrial initiative to combat haze in SE Asia provides a website which includes information about the objectives of this industrial initiative and projects implemented to reduce wildfires and haze in Indonesia.
