Detailed albedo measurements were carried out during summer and winter period in different snow and ice media in 1997-98 at different chosen sites in Antarctica. Average albedo values were found to be high in snow medium (max. 99%) moderate in shelf ice (max.90%) and very low values (max.58%) in the continental ice medium. The albedo was found to be a function of cloud amount, increasing with the amount and thickness. In white-out conditions during blizzards high albedo (Av. 83%) was found as compared to clear sky day (Av.76%) and after blizzard (Av. 78%). It showed dependency on the type of snow also. New snowfall over old snow displayed higher values (90%) than older snow (70%) and decreases with the age of snow. The interaction of electromagnetic radiation with a natural snow cover is of considerable practical interest and scientific importance. The remote sensing community requires an improved understanding of the optical properties of snow in order to correctly interpret the imagery of snow covered regions and to distinguish between snow pack and cloud covers. Radiant energy transfer is important in the thermodynamics and metamorphosis of the snow pack and is therefore of interest to those who study the mechanical and hydrological properties of the snowpack. Therefore, the establishment of relationships between the optical properties of snow and frequently measured snowpack quantities, such as liquid erties of snow and frequently measured snowpack quantities, such as liquid water content, density, surface temperature etc. would be of considerable utility.
