The Global Fire Product: daily fire occurrence from April 1992 to December1993 derived from NOAA AVHRR data

Global active fire maps have been produced over a 21-month period from Apri l 1992 to December 1993. A contextual active fire detection algorithm has b een applied to the NOAA AVHRR (National Oceanic and Atmospheric Administrat ion Advanced Very High Resolution Radiometer) 1.1 km images provided by the IGBP-DIS (International Geosphere-Biosphere Programme Data and Information System) 1 km AVHRR Global Land Project data set. The Global Fire Product ( GFP) is composed of daily fire position tables, 10-day synthesis raster for mat maps containing fire density and cloud/no-data information; it is now a vailable as the first global scale description of the spatial and temporal distribution of active vegetation fire. In answer to science community requ irements the GFP supplies information which can be used to estimate fire im pacts on atmospheric chemistry, climate, land use and land cover changes.
