Abstract
The purpose of this study is to estimate evapotranspiration in a wide area using a correlation relationship between NDVI and evapotranspiration. Factors which control evapotranspiration can be considered that these are reflected by the vegetation condition.In order to grasps the vegetation condition at some point, NDVI calculated from NOAA-AVHRR data is utilized. A land cover classification is performed in Korean peninsula using a seasonal variation of the NDVI, and the relationship between NDVI and evapotranspiration is estimated for every land cover category. Then, the dis.tribution of evapotranspiration can be estimated in Korean peninsula including North Korea where meteorological data are unavailable.
