Abstract

Remote sensing data acquired by satellite or airborne sensor need on ground validation measurements. As concern volcanoes monitoring, important information may be retrieved by observing these targets in the InfraRed spectral range. A portable μFTIR (Fourier Transform Infrared Interferometer) capable of making sensitive and accurate measurements of radiance and emissivity of surface in the (600-5000 cm^-1) spectral range with a spectral resolution of 2 cm^-1 is available at the remote sensing laboratory of INGV (Rome). These kinds of measurements are very important firstly for the validation of remote sensed data and secondly for the improvement of many gas models used in volcanology for the diagnosis of volcano inner state. On 2003 μFTIR in situ spectral emissivity measurements were made during field surveys on selected test sites on Mount Etna. This area was observed also by a Fourier interferometer (MIROR) on board on a Dornier 228 and by ASTER a satellite borne sensor. The MIROR and ASTER data have been calibrated and compared with ground measurements. The agreement suggested to organize periodic measurements on selected test sites of Italian volcanic regions e.g. Solfatara and Stromboli volcano.
