本文介绍了2005年6月28日在欧洲气象中心实施的降雨影响卫星观测的一维+四维变分同化系统的实施情况。第一部分描述了利用特殊传感器微波/成像仪(SSM/I)微波辐射观测估算总柱水汽(TCWV)的云和降水中一维Var反演方案的方法和性能分析。这一部分描述了4D-Var中TCWV观测的技术实现以及影响分析。
This paper presents the operational implementation of a 1D+4D‐Var assimilation system of rain‐affected satellite observations at ECMWF performed on 28 June 2005. The first part describes the methodology and performance analysis of the 1D‐Var retrieval scheme in clouds and precipitation that uses Special Sensor Microwave/Imager (SSM/I) microwave radiance observations for the estimation of total‐column water vapour (TCWV). This part describes the technical implementation of the TCWV observations in 4D‐Var as well as the impact analysis.
