The 1998 "burning" season in Mexico was outstanding. Hurricanes, low temperatures and unexpected snowfall contributed to the disposal of large quantities of fuelgrass, shrub and wood. Based on the processing of channel 3. 120 AVHRR images from January to June 1998, an evaluation of burned areas is presented. Up to 8 147 pixels assuming the presence of fire were recorded. In order to check accuracy of band 3 derived data, 3 312 sites corresponding to fires were crossed to fires estimated from imagery. About 94% of accuracy was assessed for the map presented here.
