Evaluation of tropical cloud and precipitation statistics of Community Atmosphere Model version 3 using CloudSat and CALIPSO data
[1] The combined CloudSat and CALIPSO satellite observations provide the first simultaneous measurements of cloud and precipitation vertical structure and are used to examine the representation of tropical clouds and precipitation in the Community Atmosphere Model version 3 (CAM3). A simulator package utilizing a model‐to‐satellite approach facilitates comparison of model simulations to observa...
متن کاملTemporal and Spatial Variations of Global Deep Cloud Systems Based on CloudSat and CALIPSO Satellite Observations
The spatial and temporal global distribution of deep clouds was analyzed using a four-year dataset (2007–10) based on observations from CloudSat and CALIPSO. Results showed that in the Northern Hemisphere, the number of deep cloud systems (DCS) reached a maximum in summer and a minimum in winter. Seasonal variations in the number of DCS varied zonally in the Southern Hemisphere. DCS occurred mo...
متن کاملRadiative fluxes in the ECHAM5 general circulation model
Radiative fluxes in the ECHAM5 general circulation model (GCM) are evaluated using both surface and satellite based observations. The fluxes at the top of the atmosphere (TOA) are generally in good agreement with the satellite data. Larger deviations in simulated cloud forcing are found especially at lower latitudes where the shortwave component within the intertropical convergence zone is over...
متن کاملArctic cloud macrophysical characteristics from CloudSat and CALIPSO
a r t i c l e i n f o The lidar and radar profiling capabilities of the CloudSat and Cloud-Aerosol Lidar and Infrared Pathfinder (CALIPSO) satellites provide opportunities to improve the characterization of cloud properties. An Arctic cloud climatology based on their observations may be fundamentally different from earlier Arctic cloud climatologies based on passive satellite observations, whic...
متن کاملAutoconversion rate bias in stratiform boundary layer cloud parameterizations
Because of their large grid-box size, global climate models do not explicitly represent small-scale processes occurring in cloud systems in the marine boundary layer. One such process, which is thought to have an important climatological effect, is the production of warm rain. Parameterizations of this process typically partition the liquid water into a cloud and a rain component. The rate of c...
