Comments of the GFMC to the Smoke-Haze Problems in Southeast Asia
GFMC Freiburg, Germany, 22 August 2005. On Sunday 21 August 2005 the weather situation remained more or less unchanged. Satellite images reveal cloud coverage and rains over most of the Indonesia archipelago. The National Meteorology and Geophysics Agency of Malaysia is predicting continuing precipitation in the region. On Saturday 20 August only nine of the 51 monitoring stations reported moderate levels, while no unhealthy air quality reading was reported in the peninsula, Sabah or Sarawak. However, as GFMC Operations underscore, the rains may not change the situation rapidly. Fires burning in deep peat layers will not be extinguished by short precipitation events.
Following the response by the UNOCHA/UNEP Joint Environment Unit and the GFMC a meeting of both units with UNEP Executive Director Klaus Toepfer is scheduled tomorrow at the UN Geneva, 23 August 2005.
The following information is taken from the following websites of the Indonesian Ministry for Forestry and reflects the situation back in the 1990s when land-use fires burned in the same regions of Sumatra, especially in Riau Province in a similar way as they continue in 2005:
I. Monitoring of Smoke-Haze and Active Fires (land-use fires and wildfires)
Regional Smoke-Haze Monitoring
The Meteorological Division of the Singapore National Environment Agency provides a daily updated map showing active fires (land-use fires, wildfires), smoke haze and surface wind directions within the South East Asian region.

Fire Activity Monitoring in South Sumatra
The South Sumatra Forest Fire Management Project provides regular fire activity maps based on the products of the MODIS Rapid Response System: http://www.ssffmp.or.id/ssffmp/fwi-2.asp?id=2
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.
Fire Weather Index (FWI) forecast for this week (left) and the predicted FWI total for next month (right) for the Western Pacific (1-3) and the Pacific Ocean (4-6) regions. The weekly total forecast and the monthly forecasted total refer to 00:00 hrs UTC, which is local noon at dateline (180° longitude). Forecast time is 12:00 hrs noon UTC (Greenwich) corresponding to local evening time in mainland and insular SE Asia. (Source: ECPC Fire Weather Index Forecast)
