Radiometric, Derived Quantities and Models

The first Quality Measurement Experiment (QME) implemented in the ARM Experiment Center, this VAP compares the ARM microwave radiometers against the output from an Instrument Performance Model (Schroeder and Westwater), which is based upon the Leibe 1987 microwave absorption model. The thermodynamic profile from the radiosonde is used to drive the model, which outputs brightness temperatures at the same frequencies as the radiometer. The results from this QME are used to evaluate the MWR and radiosondes, update the tuning functions used in the MWR, and check the MWR's calibration.
