Preliminary results on snow surface reflectance and its dependence on grain size studies at Ny-Ålesund

Snow spectral reflectance measures can supply valuable information on snow cover characteristics especially analyzing near IR wavelength interval in which snow reflectance is inversely proportional to grain size. During 2011 CICCI campaign, measurements of the snow reflectance were carried out with a portable spectroradiometer (FieldSpec, Analytical Spectral Devices, Boulder, CO, USA), that allows reflectance data in the 350-2500 nm spectral range to be acquired by three separate spectrometers, that operate in the ranges 350-1050 nm, 900-1850 nm and 1700-2500 nm, with 10 nm resolution....
