The Korea Meteorological Administration (KMA) forecasts the weather using a Numerical Weather Prediction (NWP) system. National Meteorological Satellite Center (NMSC) of KMA has been supporting satellite data to Numerical Modeling Center of KMA for data assimilation since 2011. NMSC provide not only meteorological products of satellite but also ground and space based Global Navigation Satellite System (GNSS) data for NWP model. In addition, we have been studying on techniques of GNSS Radio Occultation (RO) to improve the accuracy in retrieving atmospheric vertical profiles. Also, we have developed monitoring system for GNSS RO data to monitor acquisition and to analyze data before transmission to NWP system. We are also studying about GNSS RO data preprocessing progress in order to understand principles more well for meteorological application. In this presentation, we will show some results on the KMA's NWP model of the GNSS RO data.
