Joint Seminar: A Comparison of Cloud and Radiation Properties in CMIP5 Models Using ISCCP and MISR Instrument Simulators

A necessary test of the representation of clouds in climate models is an evaluation of cloud properties against cloud observations. This apparently straightforward task is often complicated by fundamental differences between quantities observable from space and those simulated by large-scale models, as well as by uncertainties in satellite retrievals of cloud properties. Satellite instrument simulators like those included in the CFMIP Observation Simulator Package (COSP) attempt to overcome these challenges by creating synthetic satellite observations from model properties. Here, we use diagnostics from these simulators to evaluate cloud properties in AMIP-type simulations from the GFDL AM3, NCAR CAM4 and CAM5, CCCma CanAM4, and UKMO HadGEM2 against ISCCP and MISR observations. Cloud radiative effects are evaluated against CERES-EBAF.
