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 afternoon image of Southeast Asia, including (left to right) Thailand, Cambodia, Laos, and Vietnam, captured by the Moderate Resolution Imaging Spectroradiometer (MODIS) on the Aqua satellite to the same area captured by Terra MODIS in the morning. Note the dramatic increase in fires (red dots) in the afternoon image. This image was acquired Jan. 31, 2003.

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 map is generated on the basis of two satellite sensors (NOOA-AVHRR, DMSP/OLS).
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.

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.

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.
