Description:
The reflectance spectra were measured with a FieldSpecPro from 350 nm to 2500 nm during a
fieldwork in June 2007. The reflectance has been compared with reflectance obtained by multispectral
Advanced Space borne Thermal Emission and Reflection Radiometer (ASTER) and by hyper
spectral EO1-Hyperion satellites. Prior the comparison, reflectance spectra have been convolved
with ASTER and EO1-Hyperion spectral functions. The results show percentage errors in
accordance to those present in literature in the ASTER SWIR range. However, some differences
have been confirmed for the ASTER reflectance product (ASTER_07) in visible channels. Regarding
EO1-Hyperion, a good agreement of reflectance against field measurement has been found resulting
in 5% percentage maximum error in the VIS and up 30% in SWIR spectral range. The capacity
of reproducing spectral feature by EO1-Hyperion has been checked on bright pixels (ice-snow) in
the acquired image.

The authors thank D. Pieri, ASTER science Team Member, for the data acquisition planning support and the Jet
Propulsion Laboratory, California Institute of Technology for providing ASTER imagery. We further thank the
EO1 team for their free data policy, C. Carli for his support in the field measurements. We thank B. Behncke, A.
La Spina and F. Murè (INGV Catania) for logistic support and assistance with their knowledge of the Mt. Etna
area. A special thanks to Prof. Andrew Hardy for his English check.
