Abstract
Components of water balance are derived in the Korean Peninsula. Because enough data are not available in the northern part of the peninsula, an alternative is adapted in this paper. At first, a set of monthly NDVI maps of the peninsula is derived and utilized for landcover classification and for evaluation of evapotranspiration distribution. Relationship between NDVI and evapotranspiration is confirmed from the groundtruth data in the southern part of the peninsula. The results are applied to estimate the evapotranspiration distribution over the peninsula. Combining the evapotranspiration, precipitation distribution and runoff calculated with a tank model, water balance is examined in both of the north and south parts of the peninsula. Some index maps are also derived and the climatic characteristics of the peninsula are shown.
