A Tool for Multi-Platform Remote Sensing Processing

Thermal remote sensing of volcanic activity can be efficiently dealt with by observations carried out at high repetition rates by high spectral resolution radiometers, much more than by observations carried out at high geometrical resolutions. This held true for radiometers AVHRR (in spite of the small dynamic range of channels, mainly MIR, unsuited to volcano observation) and MODIS, and was recently demonstrated to hold true also for SEVIRI, onboard the geosynchronous platforms MSG1 and MSG2. A digital image processing tool in near-real-time of thermal infrared satellite data acquired by MODIS and AVHRR sensors (low temporal resolution) has been successfully experimented on Etna volcano. This multi-approach method was integrated with the information coming from SEVIRI sensor that allows to obtain a high temporal resolution. We conducted a preliminary study to verify the applicability of the SEVIRI as an instrument suitable to be employed in an operational system of early hot spot detection. This multi-platform system has been validated and tested on the Mt Etna 2008 eruption. [ DOI : 10.1685/CSC09281] About DOI
