Properties of the Snow-Firn Cover of Greenlandic Glaciers from the Satellite Measurements of Its Scattering Index

V. V. Asmus, M. V. Bukharov, N. S. Mironova, and E. A. Sizenova

A new approach to the daily monitoring of properties of the snow-firn cover of Greenlandic glaciers based on the maps of the scattering index computed from the AMSU satellite radiometer measurements is considered. The boundaries of areas with different dispersing properties of snow and their seasonal variations in 2010–2011 are determined. A high daily variability of the scattering index of snow-firn cover in summer and in transitional seasons is revealed. The analysis of probable reasons for the variability of the scattering index of snow-firn cover of glaciers is carried out.
