The satellite data is very useful for observation of the regional environment. However, it has been rather difficult to obtain quantitative data from satellite image data. Recently the number of ground observing stations has been increasing. The interpretation of the image data became easier and clearer. This report shows some examples how to utilize the NOAA data for observation of environment. i.e., the observation of snow covered area, estimation of evapotranspiration and evaluation of NPP are shown as examples. Snow covered area can be obtained correctly by comparing multi-spectal senser. Snow map made from some images makes possible to evaluate snow storage. Evapotranspiration can be estimated by considering the correlation with NDVI which is calculated from the satellite data. The distribution of NDVI also makes possible to evaluate Net Primary Production.
