Short summary
A process to characterize a ground-based microwave radiometer by comparing measured radiance with a reference data, prepared by the radiative transfer simulation with the input of temperature and humidity profiles from NWP model is introduced. When the data affected by clouds and erroneous absolute calibration is compared, the data show a better than 0.97 and 0.5 K of regression coefficient and bias, respectively. However, there is unresolved discrepancy of about 2 K at the lower frequencies.
