CWFMSBeing developedMeasurements are: Fire Radiative Power (FRP), hotspot locations, rate of spread, burned area mapping. Data products generated: 1) Fire maps, showing location, extent, and timing of forest fire events; 2) Fire characteristics, such as fire line intensity, rate of spread and fuel consumption; 3) Plume dynamics through smoke transport maps and plume heights; 4) Mass of carbon released into atmosphere.n/a
