Global Penetrability Statistics of CALIPSO Over Ocean Laser Samples

Abstract

Abstract:

Global penetrability statistics of CALIPSO over ocean laser samples are derived from the CALIPSO level 2 5-km lidar cloud layer products between June, 2006 and May, 2010. The effects of the changes of year, season, day/night and geographic location are discussed so as the effect of the different product versions. The results show that cloud layers are detected in about 72.2% of the total over ocean lidar profiles, and 61.4% of the cloudy samples have opaque cloud layer. That means 38.6% of the cloudy samples can get the sea surface information, and together with the cloudless laser samples, about 55.6% of the total lidar samples can be used to detect the information of the sea surface. The different product versions can cause about 9% change in the results.

Key words: spaceborne lidar, CALIPSO, opacity cloud frequency, cloud layer product
