Ice Cloud Bulk Scattering Models - Version 3 Models Now Available!

Please note: New Version 3 spectral models and imager models are based on severely roughened particles and a general habit mixture based on a set of 9 idealized ice particle habits. The single-scattering properties in each model consist of the single-scattering albedo, asymmetry parameter, extinction coefficient, extinction efficiency, total projected particle area, and scattering phase functions, all as a function of the effective diameter. The spectral models contain properties at individual solar wavelengths between 0.4 – 2.5 µm at 0.01 µm resolution. Additionally, models are now available for 35 polar-orbiting and geostationary imagers (just added 4 more on April 30, 2012). This is just the beginning - more models will become available (e.g., models with the full phase matrix, extended wavelength ranges, etc.) over time, but the documentation needs to catch up with what is currently available first.

Notice of International Cloud Retrieval Evaluation Effort

Cloud Retrieval Evaluation Workshops (CREW); The third workshop was held 14-18 November, 2011 at UW-Madison, and was sponsored by EUMETSAT. I am co-chairing this with Rob Roebeling (EUMETSAT). We are currently discussing the 4th workshop anticipated to be held in 2013.
