The Cloud-Aerosol Lidar with Orthogonal Polarization (CALIOP) aboard Cloud-Aerosol Lidar and Infrared Pathfinder Satellite Observations (CALIPSO) satellite provides a new view of cloud properties data with higher spatial resolution than former satellites devices around the world, especially optically-thin clouds. Assessment of this useful data comparing with data from groundbased measurements is an opportunity for estimating uncertainties in clouds properties obtained from satellites. That is very important for increasing the knowledge about clouds and their representation in climate models. In this paper Cloud Optical Depth (COD) lower than 5 from level 2 version 3.01 cloud profile data of CALIPSO and AErosols RObotic NETwork (AERONET) groundbased sun photometer (SP) measurements were compared during the period since 2010 to 2014. Cloud frequency is computed as a ratio between cloud measurements and all possible measurements for each instrument. A collocated measurements comparison and general statistics comparison was conducted. © Sociedad Española de Óptica.
