Remote sensing of bush fire dynamics in Central Africa from 1984 to 1988: analysis in relation to regional vegetation and pluviometric patterns
Global area coverage (GAC) data, from the advanced very high resolution radiometer (AVHRR), provide a good description of fire a calendar and, on a continental scale, a good indicator of locations of intense fire activity. Available on a daily basis back to July 1981, this is the only source of information available to determine burning patterns both on a continental scale and over long periods of time. The spatio-temporal distribution of vegetation fire in Central Africa, derived from GAC imagery, the four 1984/85 to 1987/88 dry seasons of the Nothern Hemisphere. The analysis shows a north to south gradient of fire activity in the savannah domain: this gradient of fire activity (previously related to the annual pluviometric calendar and the amount of rainfall) could not be explained by the monthly pluviometric patterns. Additional meteorological or anthropic parameters are implied. The methodology demonstrates the potential of GAC data for fire monitoring at a subcontinental scale. Current work involves the entire African continent using the 10-y period of GAC imagery.
