Snow spectral albedo, specific surface area and optical grain diameter timeseries from 5-year summer observations at two windy coastal locations of Antarctica

This dataset contains a in-situ measurements of the spectral albedo acquired during 5 summer seasons at two coastal locations close to the French research station of Dumont d'Urville, in East Antarctica. The measurements were acquired with the Multiband albedometer and corrected for stray light, cosine response of the collector and surface slope under the albedometer's footprint. The snow specific surface area and optical grain diameter were then retrieved from the spectral albedo. All details about the Multiband instrument, the measurement processing and uncertainties are provded in the accompanying paper. The dataset also contains the codes and the auxiliary data used to produce the figures of the article.
