Forest Fires Remote Sensing With Spinning Enhanced Visible And Infrared Imager Data
Authors : Hassini Abdelatif .
Abstract
The SEVIRI (Spinning Enhanced Visible and Infrared Imager) sensor on the MSG satellite provides an image every 15 minutes, so the development of an algorithm that can exploit the temporal behavior of the observations of terrestrial half-disc centered on Africa, in spite of their large pixel size, is crucial for these near-real-time applications. This paper gives an overview of the MSG SEVIRI instrument, the general approach for the active fire monitoring, and the description of the algorithm together with the practical application of the tests and the algorithm. The F2RSA algorithm (Active Fire Monitoring Algorithm) developed in this work is able to detect most of the existing active fires with a minimum of false alarms. The F2RSA algorithm distinguishes between Diurnal and Nocturnal periods of day. The algorithm itself is based on a simple threshold algorithm. A few results are described and discussed.
