How to interpret these metrics
Fire radiative power (FRP) estimates thermal radiation at the time of the satellite overpass. FRP alone cannot determine burned area or damage.
MODIS and VIIRS have different resolutions and sensitivities. One fire can produce several nearby detections or repeat observations.
