The Arctic is a key element in determining the radiation budget of the earth. Within the polar regions, the net radiation (incoming solar radiation minus outgoing infrared radiation) is negative. To understand the role this energy deficit plays in the overall radiation budget, one must examine the prevalent atmospheric features of the Arctic. One such feature is a persistent layer of low-altitude, stratiform clouds found over the central Arctic predominantly from April to September (Tsay et al. 1984). These Arctic stratus clouds (ASC) modulate the earth’s radiation budget by contributing to the vertical transport of heat (Curry 1986). It is, therefore, crucial to understand the radiative properties of Arctic stratus clouds. We believe that the radiative properties of ASC are strongly coupled with their cloud microphysics. Our aim is to
