Abstract :
A retrieval algorithm of atmospheric water vapor and cloud liquid water for Advanced Microwave Scanning Radiometer for Earth Observing System (AMSR-E) was developed. The algorithm uses a simple radiative transfer model which is composed of single atmospheric layer and ocean surface. The atmospheric transmittance was derived from an iteration calculation using vertical mean temperature estimated from ancillary 850 hPa temperature data and observed AMSR-E brightness temperature. The algorithm is applicable for other microwave instruments. The retrieved atmospheric water vapor is expected to be used in Japan Meteorological Agency (JMA) operational Meso-scale analysis and forecast. In a case study on heavy ram event in Japan, assimilation of the retrieved atmospheric water vapor from Special Sensor Microwave Imager Sounder (SSMIS) showed intensified moisture flows in the Meso-scale analysis and forecast and produced a strong rainfall band in the forecast.
