2C-RAIN-PROFILE
Product Availability: Full mission availability except for anomalies and maneuver data gaps
The objective of the algorithm is to infer profiles of precipitation liquid and ice water content along with an associated surface rain rate from the CloudSat Profiling Radar (CPR) reflectivity profiles and a constraint on the Path Integrated Attenuation (PIA) of the radar beam. Key inputs to the algorithm flow from the 2C-PRECIP-COLUMN product, which flags profiles for precipitation, determines the freezing level, determines the precipitation type (convective/stratiform/shallow), and provides an estimate of the magnitude and uncertainty of the PIA. The algorithm further makes use of ancillary temperature and humidity estimates from the ECMWF analysis provided in the ECMWF-AUX product.
