Outline of Final Research Achievements

This study is aimed at developing novel process-oriented methods based on satellite data, as represented by satellite data simulators, in order to evaluate numerical weather models. The meteorological parameters such as the precipitation efficiency and cumulus mass flux, known traditionally to be difficult to estimate from satellite observations, are successfully retrieved from a combined use of cutting-edge Earth-observing satellites including CloudSat, Aqua, and TRMM. The findings would open a new pathway for the observational assessment of, for example, cumulus parameterizations implemented in climate models.
