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 inter- ferometer 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...
