Retrieval of subpixel fire temperature and fire area in moderate resolution imaging spectrometer

Abstract

The ability to retrieve information at subpixel spatial resolution from satellite with more than one channel in the thermal infrared spectral range had benefited the monitoring of forest fires. With better sensors, the severity of fire and the degree of damage can be estimated by retrieving fire fraction and fire temperature using Dozier procedure. A sensitivity analysis was also performed to estimate the uncertainty in the retrieval of fire fraction and fire temperature as a result of inaccurate determination of emissivity and background temperature.
