Etna 2003 Field Campaign: Calibration and Validation of spaceborne and airborne Instruments for volcanic Applications

Abstract

The field measurements campaign made in July 2003 on Etna, Vulcano Island and Campi Flegrei was dedicated to the calibration and validation of airborne and spaceborne data. The campaign activities were relevant part of two ASI funded projects: 1) FASA, dedicated to airborne system and data validation/calibration 2) HypSEO, dedicated to multispectral an hyperspectral spaceborne data validation/calibration on specific test areas. The airborne campaign was organized in the frame of a three-year project funded by ASI and DLR as it represented the flight test of the FASA system, which combines a Fourier interferometer in the MIR-TIR region and an imager (ABAS). The main objectives of this proposal are: 1. Design and implementation of an airborne system for the Fourier Spectrometer MIROR and ABAS (Bird Airborne Simulator); 2. Airborne Operational tests of the FASA system over the main Italian volcanic areas (i.e. Etna, Stromboli and Vulcano) and possibly on controlled forest fires (Germany); 3. Organization of the necessary ground campaign for calibration and validation of the acquired data; 4. Development of the algorithms for the selection of the “spectral windows” and for the determination of the presence of some gasses: in particular SO2, CO2, H2S and other gasses of volcanic origin.
