Fire detection from space: correction for the distorting effect of the atmosphere

摘要

An analysis of the results of spacebome fire detection in the Tomsk Region of Western Siberia allows us to conclude the following. Complex situations often arise in satellite observations in the presence of the atmospheric aerosol or the semitransparent cloudiness when standard algorithms cannot detect automatically small-sized fires from space. In such situations, the problem can be solved successfully by using the atmospheric correction of satellite measurements for the distorting effect of the atmosphere based on atmospheric radiance/scattering models. In this case, a priori information on the optical and meteorological parameters of the atmosphere and on the geometry of observations is used. In the present study, some results of numerical simulation and atmospheric correction for the distorting effect of the atmosphere in the problem of fire detection are given.
