Characterization of the spatio-temporal patterns of global fire activity using satellite imagery for the period April 1992 to March 1993

Funded under: FP5-EESD

Abstract

Twenty one months of global, daily, daytime acquired satellite data at 1 km resolution, from April 1992 to December 1993 have been processed to give the positions of active vegetation fires. Two methods of characterizing the spatio-temporal pattern of vegetation fire are discussed. The first applies principal component analysis to the monthly series of fire count products. The second approach defines and extracts a number of spatial and temporal parameters from the gridded product. Three of these parameters are used in a clustering procedure. The two characterizations, while emphasizing different aspects, synthesize the main spatio-temporal characteristics of global fire distributions.
