Radiative power of wildfires in Siberia on the basis of TERRA/Modis imagery processing

摘要

Variety of radiation power of wildfire was investigated by processing TERRA/Modis imagery in 4 μm spectral band. Fire radiative power (FRP) was used for calibrating high-temperature event database obtained by the satellite technique. An analysis was performed on the database of Siberian wildfires for 2010- 2012. Dynamics of FRP was investigated for a number of wildfires including some cases of crown fire. FRP variation was evaluated for various forest zones of Siberia. Classification of wildfires was elaborated in terms of FRP value as a GIS-layer over the territory of Siberia.
