Time-series of snow spectral albedo and superficial snow specific surface area and impurity content at Col de Porte, French Alps, 2014
Spectral albedo has been measured at Col de Porte from January until end of April 2014 in the visible and near infrared (400 - 1050 nm) at sub-hourly resolution using a home-made spectral radiometer. Calibration follows the procedure described in Picard et al. 2016 (doi:10.5194/tc-10-1297-2016). The...
