Paper Abstract
Based on the comparison of TMI measurements and the AWS rain rates, characteristics of rain systems over the Korean
Peninsula during summer were examined. It was found that the TMI brightness temperatures (TBs) at high frequency (85
GHz) are generally higher than those in GPROF database for the same rain rate. With these characteristics kept in mind,
cloud resolving model simulations were performed by modifying intercept values in the Marshall-Palmer size
distribution relationship. The intercept values of graupel and snow were assumed to twice the default value (snow: 1.0 ×
108 m-4, Graupel: 4.0 × 106 m-4).
Microwave brightness temperatures at passive microwave radiometer frequencies and vertical reflectivity at precipitation
radar frequency are calculated by repeated application of the one-dimensional version of Eddington's approximation1.
The hydrometeor profiles were selected by comparing with TRMM PR reflectivities. By adding those selected profiles to
the convective profiles of GPROF database, we modified database for the rain retrieval over the Korean Peninsula.
Rainfall retrievals by using the new database show that quality is significantly improved, indicating the need of
algorithm locally more suitable.
