Research Abstract

In this research, the cloud microphysics data assimilation system, which improves water vapor and cloud water amount in numerical weather prediction model, is improved by using multiple satellite observation products. Sea surface temperature estimated from satellite observation has small effect but sea surface wind shows significant change. Sensitivity analysis for cloud top height (CTH) suggested that appropriate information of CTH distribution can largely improve assimilation result.
