Abstract

Usefulness of satellite systems in monitoring fires has been being recognized for years, but satellitebased methods have been originally applied only to polar-orbiting sensor data like NOAA-AVHRR (National Oceanic and Atmospheric Administration - Advanced Very High Resolution Radiometer), ERS-(A)ATSR(-2) (European Remote Sensing Satellite - (Advanced) Along Track Scanning Radiometer), and more recently EOS-MODIS (Earth Observing System - Moderate Resolution Imaging Spectroradiometer). In this context, geostationary sensors, despite their coarser spatial resolution (3-4 km), have been recently taken into account thanks to their very high time repetition rate which may actually give more chance to detect short-lived fires, starting fires or fires with activity which has a strong diurnal cycle. This seems particularly important for European Countries (mainly in the southern part) which often suffer from short-lasting but noxious fires and/or events frequently occurring between 12:00 and 14:00 local time. European Countries may benefit of MSG-SEVIRI (Meteosat Second Generation – Spinning Enhanced Visible and Infrared Imager) geostationary sensor offering a temporal resolution from 15 to 5 (in case of MSG Rapid Scanning System) minutes. SEVIRI-based fire products may give support to ground surveillance systems and help Civil Protection Services in timely detecting events for rapidly intervening before fire spreading as well as in monitoring ongoing events for optimizing ground and aerial resources. In the last years, many algorithms of fire detection have been adapted to MSG-SEVIRI starting from other geostationary sensors (e.g. GOES - Geostationary Operational Environmental Satellites) or have been specifically designed for it. They are generally based on fixed thresholds (single/multiple channels or contextual methods) so that they are often a source of false alarms or show a low sensitivity in detecting small fires. Any case, their performances seem to be not adequate to civil protection requirements, mainly in Southern Europe. In this work, results of RST-FIRES (Robust Satellite Techniques for Fire detection) implemented to MSG-SEVIRI data are shown. Validation of RST-FIRES performances have been evaluated by means of a Total Validation Approach (TVA), based on a systematic check of detected hot spots through a direct ground observation of dedicated light aircrafts or ground voluntary brigades.
