Cover Story: The CloudSat 94 GHz radar provides the most complete snowfall climatology over polar regions, but accurate quantitative snowfall estimates derived from radar reflectivity (front cover) remain challenging. This work explores the value of the CloudSat 94 GHz Brightness Temperature, a novel product developed from the processing of the radar noise floor level, combined with path-integrated attenuation, a standard product derived from the reduction in the radar surface return. Results demonstrate that over ice-free ocean, where surface emissivity and backscattering are well predictable, the synergistic use of these two observables provides crucial information on the presence/amount of supercooled layers and on snow density, with potential for better constraining snowfall retrieval.
