The fire/hot spot characterization product makes use of both visible and infrared ABI spectral bands to locate fires and retrieve sub-pixel fire characteristics. The product greatly improves upon the previous fire detection product by taking advantage of the higher spatial and temporal resolution available with the GOES-R Series ABI. Forecasters use this product to monitor wildfires, and more importantly, rapid changes in individual fires. Forecasters use this product as part of an arsenal of forecasting tools aimed at helping firefighting efforts.
