In this paper we discuss the use of rotating shadowband radiometers and microwave radiometers to find shortwave cloud optical depth and cloud effective radius at two Arctic sites. These sites are the SHEBA ice camp site (a field study undertaken in 1997 and 1998) and the ARM Barrow (AK) site. Special measures are necessary to process the data from the SHEBA site to account for the harsh environment in which the instruments reside. The analysis shows that, over the summer of 1998, the median cloud optical depth athe SHEBA site is greater than the median cloud optical depth at the Barrow site. The cloud droplet effective radius is less at the SHEBA site than the Barrow site.
