AB: CloudSat was launched on April 28 2006 as a NASA Earth System Science Pathfinder satellite mission to fly the first satellite-based millimeter-wavelength cloud radar (94 GHz) to advance our understanding of cloud abundance, distribution, structure and radiative properties. One of the key CloudSat objectives is to spur improvements in climate prediction by providing critical observation against which model representations of clouds can be effective evaluated and constrained. This talk presents results of research that utilizes the new data from CloudSat in combination with other sensors of the A-Train to expose systematic errors in weather prediction and climate models of various types. Comparisons between cloud and precipitation statistics derived from A-Train observations and global clouds resolving models ranging from global cloud resolving models, the so called multi-scale modeling framework (MMF) to current forecast and climate models will be highlighted.
