In this investigation, we examined the spatial and temporal characteristics of the visible and infrared albedo of sea ice In a seasonal zone using Advanced Very High Resolution Radiometer (AVHRR) visible and near-infrared data. Sea ice surface albedo data were inverted from satellite top-of-atmosphere radiances by correcting for sensor calibration drift and estimating atmospheric and view angle effects. Pairwise comparison methods and principal component analysis was used to identify the major and minor scale variance structures in the multitemporal satellite albedo dataset. Results indicate that during the onset of melt conditions, there is large scale variability in the regional patterns of surface albedo in a marginal ice zone. Analysis of satellite and surface data indicate that these surface albedo patterns conform closely to sea ice snow distribution. Also, time and conditions of consolidation appear to determine the macro-morphological characteristics of the ice surface, which in turn control the time series and spatial variability of sea ice surface albedo.
