Uncertainty Analysis for CloudSat Snowfall Retrievals

Experimental Light Rainfall and Snowfall Products for Cloudsat

When it launches next spring CloudSat, a component of the A-Train formation of satellites, will carry the first millimeter wavelength cloud radar in space. In addition to its stated objective of making a global survey of cloud microphysical properties, the CloudSat 94 GHz Cloud Profiling Radar (CPR) is also well-suited to the problem of determining the distribution of light rain and snow that c...

CloudSat-Based Assessment of GPM Microwave Imager Snowfall Observation Capabilities

The sensitivity of Global Precipitation Measurement (GPM) Microwave Imager (GMI) high-frequency channels to snowfall at higher latitudes (around 60◦N/S) is investigated using coincident CloudSat observations. The 166 GHz channel is highlighted throughout the study due to its ice scattering sensitivity and polarization information. The analysis of three case studies evidences the important combi...

Snowfall Detectability of NASA’s CloudSat: The First Cross-Investigation of Its 2C-Snow-Profile Product and National Multi-Sensor Mosaic QPE (NMQ) Snowfall Data

This study investigates snowfall detectability and snowfall rate estimation with NASA’s CloudSat through the first evaluation of its newly released 2C-SNOW-PROFILE products using the National Mosaic and Multisensor QPE System (NMQ) snowfall products. The primary focus is on the detection and estimation of surface snowfall. The results show that the CloudSat product has good detectability of lig...
