Observations of Arctic cloud height, depth, and depolarization ratio have been obtained with the Environmental Technology Laboratory's DABUL (Depolarization And Backscatter Unattended Lidar) system which has been deployed as part of the year-long SHEBA (Surface Heat Budget of the Arctic Ocean) experiment (1997-1998). Monthly and seasonal climatologies of these parameters will be presented. Preliminary analysis has already shown a surprising amount of water-phase clouds throughout the polar winter which has important implications for modeling and modeling parameterizations. Combining lidar measurements with radar, radiosonde, and radiometer will be discussed and examples presented to highlight integrated measurements and the potential information available.
