WebThe ABI fire algorithm is a dynamic, multi-spectral, thresholding contextual algorithm that uses the short-wave 0.64 μm (ABI Channel 2, when available during the daytime) and the 3.9 μm and 11.2 μm bands (ABI Channels 7 and 14) to locate fires and retrieve sub-pixel fire characteristics. WebDec 10, 2024 · It is expressed as the daily average of the fire radiative power (FRP) observations made in 125 km grid cells and expressed in the units of [mW/m2]. The rate of release of thermal radiation by fire is believed to be related to the rate at which fuel is being consumed and smoke produced.
WebJun 3, 2024 · This study analysed the characteristics of the recent (2024–2024) wildfires that occurred in the USA, Brazil, and Australia using Moderate Resolution Imaging Spectroradiometer (MODIS) active fires (AF), fire radiative power (FRP, MW) and burned area (BA) products.
