The CloudSat Snow Profile product (2C-SNOW-PROFILE) provides estimates of vertical profiles of snowfall rate along with snow size distribution parameters and snow water content for radar reflectivity profiles observed by the CloudSat Cloud Profiling Radar (CPR) which, based on an evaluation of the profile and ancillary data, appear to coincide with snow at the surface. For these profiles, the product also estimates snowfall rate at the surface. Because of ground clutter, the CPR cannot reliably measure reflectivities near the surface.
