Mt. Teide and Mt. Etna Volcanic Rocks Characterization (VIS-IR) at Different Scales and its Organization in a Spectral Library

In order to calibrate and validate remote sensing data, information derived from laboratory and in situ measurements are needed. Periodically campaigns are organized to perform measurements and samplings to retrieve spectral and geochemical information. Information are very important to improve the theoretical model and to realize a classification. During 16-22 September 2007 a field campaign was performed on Mt. Teide planned in the frame of the European Community project (Preview). Surface characteristics of rocks in the caldera area were measured to validate satellite images acquired during the same campaign time window by ASTER sensor. Besides a Micro-FTIR (Fourier Thermal Infrared spectrometer) was used to measure the surface emissivity of the surface material during the early hours of the day and of the night. Also a Field Spec Pro instrument was used to acquire reflectance spectra in the VIS-SWIR spectral range. Subsequently, laboratory spectral measurements were performed on many representative samples. In the present work, we present the spectral library implemented to show and access the results.
