As part of the Cloud-Associated Parameterizations Testbed, weather hindcasts with the new Community Atmosphere Model Version 4 are performed for every day in the period between May 2008 and April 2010. Analysis will focus on comparison of model simulations to ARM observations of radiation, clouds, rainfall, and precipitable water and satellite observations of the International Satellite Cloud Climatology Project. The drift of the model from the initial to climate states will be investigated as well as the ability of the hindcasts to reveal information relevant to understanding the model’s biases in simulating the climate at the locations of the ARM sites. To the extent possible, attention will focus on all seasons and all sites to provide a broad view of the strengths and limitations of the model in simulating moist processes.
