explicit cloud boundary information not available through conventional means ( Stephens et al. 2018 ). It is the goal of this paper to revisit the role of distinct cloud types in Earth’s energy budget within the context of the new vertical dimension provided by CloudSat and CALIPSO . Since 2006, the active sensors aboard CloudSat and Cloud–Aerosol Lidar and Infrared Pathfinder Satellite Observations ( CALIPSO ) have provided detailed near-global observations of cloud vertical structures

– CALIPSO – CloudSat –MODIS (CCCM) product ( Kato et al. 2010 , 2011 ), which collocates irradiance derived from the Clouds and the Earth’s Radiant Energy System (CERES) with cloud, aerosol, and surface properties retrieved from the Cloud–Aerosol Lidar and Infrared Pathfinder Satellite Observations ( CALIPSO ) Cloud–Aerosol Lidar with Orthogonal Polarization (CALIOP), the CloudSat Cloud Profiling Radar (CPR), and the Moderate Resolution Imaging Spectroradiometer (MODIS). The product was designed to

time scales. However, at high latitudes the number of ground sites is limited. Since the EBAF SFC SW fluxes depend strongly upon cloud information from MODIS, it is useful to compare MODIS-based cloud information over the Arctic with active instruments such as Cloud–Aerosol Lidar and Infrared Pathfinder Satellite Observations ( CALIPSO ) data ( Winker et al. 2010 ). Figures 3a–c compare MODIS and CALIPSO cloud fractions for daytime ocean north of 70°N during boreal summer months between 2006

climate ( Kjellsson 2015 ; Laliberté et al. 2015 ). In this study, we revise entropy budget estimated by earlier studies using satellite observations that have been taken since March 2000. We use cloud and aerosol properties derived from satellites to estimate entropy production by the absorption of shortwave irradiance and by the emission of longwave irradiance to space. Radiation also carries entropy, but we primarily focus on entropy produced by heating and cooling within the atmosphere and at
