Global distribution and characterization of vegetation fires using NOAA AVHRR data

A temporal series of global coverage satellite data for the 12 month period April 1992 to March 1993 has been processed using a fire detection algorithm to record the positions of all vegetation fires observed. Fires are found to occur in almost all regions of the world, however 70% of all events detected are within the tropical belt. The spatial and temporal variations in the fire patterns are discussed and the main vegetation types that burn are identified. A methodology for parameterizing these distributions as a small number of classes is proposed and the geographical distribution of these classes is discussed.
