FIRE DETECTION FREQUENCY PERFORMANCE BASED ON GEOSTATIONARY AND POLAR-ORBITING SATELLITES BLENDING FOR FIREFIGHTING DISPATCH

Active fire time series from the VIIRS and MODIS sensors bring 8 possibilities of fire detection when integrated in a 24 hours timeframe. GOES-16 satellite has a geostationary orbit and produces one image every 10 minutes. In order to reduce the window without fire detection between polar orbit satellites passes, Censipam has integrated an automatic status into the active fire event product that considers the integration of GOES-16 satellite. The goal of this paper is to present the integration methodology and, as a result, show the performance of blended temporal resolution from geostationary and polar-orbiting satellites and its impact in fire detection. The result showed that 14% of fire events from June to September 2022 intersected with GOES data. For medium, large and very large events, it reached about 100%. The average increase in detection was about 100% higher for each event area class, when compared to the smaller one.
