New Diagnostics of CAM from DART

The Data Assimilation Research Testbed (DART) is a community software facility that can be used for all the above purposes. DART provides a variety of ensemble filtering (EF) algorithms. The distributed code (http://www.image.ucar.edu/DAReS/DART) includes a variety of low-order models for educational purposes and geophysical model interfaces (CAM, AM2, WRF, ... ) which can be used for model intercomparison in the context of identical observations and assimilation algorithm. EF uses an ensemble of (CAM) model states, influenced by observations, to estimate the probability distribution of the atmospheric state.
