Impacts of RO data on rainfall forecasts of heavy rainfalls and typhoon developments

[ABSTRACT]Radio waves (RWs) that are transmitted from satellites of the Global Navigation Satellite System (GNSS) are delayed and bent by atmosphere in which the paths of the RWs pass before reaching low earth orbit (LEO) satellites. In radio occultation (RO) observations of GNSS satellites, information of water vapor and temperature is obtained from the bending angle or delay of the RWs. In this presentation, the results of data assimilation (DA) experiments of GNSS RO data in the Meteorological Research Institute (MRI) and the recent usage progress of GNSS RO data in the operational global DA system of the Japan Meteorological Agency (JMA) are explained.
