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.

采用卫星遥感技术和数值模拟相结合的方法，研究了大陆尺度上的水和热流。首先，采用本研究新提出的算法对各种通量进行估计。特别是对气溶胶、云性质和土壤湿度等物理量进行了新的估计。二是基础设施先进。建立了GMS数据采集系统。编制NOAA-GAC数据集。这些资产以后将在这里使用。第三，研究了如何利用卫星数据进行数值模拟。研究表明，高度计资料在海洋资料同化中起着关键作用，而水汽资料对天气预报的影响较大。
