By combining satellite romote sensing technique and numerical modelling, we would like to investigate the water and heat flow in the continental scale. First, various fluxes were estimated by applying algorithms, which was newly developed in this research. Especially, physical quantities such as aerosols, cloud properties and soil wetness were newly estimated in this study. Second, the infrastructures were advanced. GMS Date Acquisition System was established. NOAA-GAC data set were prepared. These assets will be used here aften. Third, it is investigated how to use satellite data for numerical modelling. It is shown that has moisture data has a large impact on weaher prediction and altimeter data plays a key role in ocean data assimilation.

通过将卫星romote感应技术和数值建模相结合，我们想研究大陆尺度的水和热流。首先，通过应用算法来估计各种通量，这是在这项研究中新开发的。特别是在本研究中新估计了诸如气溶胶，云特性和土壤湿度之类的物理量。其次，基础架构是先进的。 GMS日期采集系统已建立。准备了NOAA-GAC数据集。这些资产将在这里使用。第三，研究了如何使用卫星数据进行数值建模。结果表明，其水分数据对织布的预测有很大影响，而高度计数据在海洋数据同化中起着关键作用。
