The Active Fire FRP Estimation: Study on Sentinel-3/SLSTR

The estimation of thermal parameters belonging to active fires, such as fire radiative power (FRP), is a recommended method to determine fire severity. A review of the state of the art provides several semiempirical methods to estimate the FRP. On the other hand, the Sentinel-3/SLSTR instrument has two spectral channels dedicated to active-fire observation, which allows fire monitoring in a wide variety of conditions not affected by sensor saturation. This contribution analyzes these technical approaches, which are to be applied on the future Sentinel-3/Sea and Land Surface Temperature Radiometer (SLSTR) sensor in order to clarify its requirements and restrictions.
