Abstract

Abstract

The surface albedo was observed at the Ice Camp during the Chinese National Arctic Research Expedition (CHINARE) at the end of melting season in 2008. The in situ data were investigated in this paper. Several albedo parameterizations were incorporated into a one-dimensional high-resolution thermodynamic snow/ice model (HIGHTSI) to simulate local surface albedo. The observed albedo varies between 0.75 0.85 during the observation period with a slightly decreasing trend, the local change of albedo was strongly linked with snowfall/sleet and snow drift events. The trend of observed surface albedo can be captured by an albedo scheme taken snow and ice thicknesses into account. Albedo schemes with the current complexity, however, are difficult to reconstruct the short-term variability.
