MICROBASE Ensemble Data Products (MICROBASEEN) for Cloud Retrievals provides ensemble means, ensemble standard deviations and probabilistic density distributions of the cloud microphysical properties retrieved by atmospheric radiation measurement (ARM) baseline cloud microphysical algorithm (MICROBASE) at the ARM Southern Great Plains (SGP) Central Facility (CF) site. This data set is processed with a variance-based method [Chen et al., 2014] that enables a probabilitization of MICROBASE by adding normally distributed perturbations to the modes of sample-means of the input profiles at typical model temporal resolution (0.5 hour) and uniformly distributed perturbations to the empirical retrieval algorithm parameters. This data set facilitates objective validation of climate models against cloud retrievals under a probabilistic framework for rigorous statistical inferences. The data is currently available for the March 2000 intensive observational period at the ARM SGP CF site and will be extended to longer periods.
