Data from the Microwave Radiometer Retrievals version 2 value-added product (MWRRETv2 VAP) are now available for the TRacking Aerosol Convection interactions ExpeRiment (TRACER), which ran from October 2021 through September 2022 near Houston, Texas.
MWRRETv2 applies the Turner et al. (2007) optimal estimation retrieval of liquid water path and precipitable water vapor to measurements from 3-channel microwave radiometers. These radiometers provide time-series measurements of brightness temperatures at 23.8, 30, and 89 GHz. The 89 GHz channel provides additional sensitivity to liquid water, especially at low liquid water paths.
MWRRETv2 applies bias corrections to the brightness temperature data on a daily basis, using an automated bias correction process calculated across a 90-day rolling window.
More information about MWRRETv2 can be found on the VAP web page.
Scientists can use the new TRACER data set now. Access the MWRRETv2 data in the ARM Data Center. (To download the data, create an account.)
