ADVANCED ATSR WORLD FIRE ATLAS BASED ON 1.6 μm CHANNEL: 20 YEARS OF FIRE MONITORING

摘要

A new fire detection algorithm ALGO3, has been testedrnand validated for ATSR-1/-2 and AATSR. This extendsrnthe ATSR World Fire Atlas to 20 years of global nighttimernfire series [1]. Based on detection of the ATSRsrn1.6 μm SWIR band radiances during night-timernobservations, ALGO3 fully extends the WFA timernseries back to 1991 using the ATSR-1 measurements.rnThe detection capability of ALGO3 has been estimatedrnin certain case to be an order of magnitude morernefficient than the 3.7 μm algorithms (ALGO1/2). Thernvalidation has been performed comparing ALGO3rnproducts to MODIS-Terra and historical ATSR WorldrnFire Atlas ALGO1/2. Global night-time fire trends havernbeen evaluated by inspecting the time series of hot spotsrnaggregated at Continental scale, excluding the zone ofrninfluence of the South Atlantic Anomaly [3].
