This product is calculated using data from the CloudSat Profiling Radar and other sources, including radiance measurements from the MODIS instrument on the Aqua platform, with which CloudSat will orbit in close ... formation. In practice, 2B-CWC simply obtains visible optical depth from the 2B-TAU product. A radar-only version of the retrieval has been implemented for use during the nighttime half of CloudSat's orbit when visible optical depth information will not be available. For continuity, the radar-only retrieval will also be run during the daytime half of the orbit.
