Description

We will present preliminary comparisons of single-layer liquid cloud microphysical retrieval products for several cases during the deployment of the ARM Mobile Facility (AMF-1) at the Black Forest Germany in 2007. The retrievals that are compared include a new version of the MICROBASE algorithm which accounts for attenuation at W-band radar frequencies, the mixed-phase cloud property retrieval algorithm (MIXCRA; Turner 2005) which retrieves cloud optical depth and cloud particle effective radius from Atmospheric Emitted Radiance Interferometer (AERI) high-resolution infrared radiance measurements and lidar cloud boundaries, and the Integrated Profiling Techniqur (Loehnert et al. 2004) an optimal estimation technique which uses a combination of a prior, cloud radar and microwave radiometer observations (Ebell 2010). These retrievals which represent a wide-range of complexity are compared to define and quantify their variability. Future plans involve the evaluation of these (and other) retrievals though a radiative closure study.
