During July 2003 a new airborne system named FASA was tested on Italian volcanoes. FASA that stands for Fire Airborne Spectral Analyzer, is a system devoted to high temperature events study. The payload on the airborne consisted of an imager (ABAS) and an high resolution Michelson interferometer with rotating retroreflector MIROR operating in the nominal infrared 2.5-18 μm range. MIROR was developed by DLR and adapted for airborne measurement by INGV that provided an opto-mechanical interface and a calibration unit software control. By using three black body sources at different temperature is possible to compute instrumental transfer function and reduce instrumental noise. In this study we describe pre-flight test and the in flight calibration results. Preliminary results of radiance spectra on the Mount Etna surface and emissivity are shown.

Abstract
During July 2003 a new airborne system named FASA was tested on Italian volcanoes. FASA that stands for Fire Airborne Spectral Analyzer, is a system devoted to high temperature events study. The payload on the airborne consisted of an imager (ABAS) and an high resolution Michelson interferometer with rotating retroreflector MIROR operating in the nominal infrared 2.5-18 μm range. MIROR was developed by DLR and adapted for airborne measurement by INGV that provided an opto-mechanical interface and a calibration unit software control. By using three black body sources at different temperature is possible to compute instrumental transfer function and reduce instrumental noise. In this study we describe pre-flight test and the in flight calibration results. Preliminary results of radiance spectra on the Mount Etna surface and emissivity are shown.
