Abstract: The purpose of this study was to assess the climatic and hydrological drought of Korean peninsular using NOAA/AVHRR satellite images and national hydrological monitoring data. Climatic drought was evaluated by climatic water balance analysis. According to the climatic water balance analysis, water deficit and surplus distributed maps were created from spatial rainfall, soil moisture, and actual and potential ETs map. The results clearly showed that the temporal and spatial characteristics of dryness and wetness were detected and mapped based on the wetness index. Hydrological drought was evaluated by MSWSI (Modified Surface Water Supply Index) based on SWSI. The results were compared to PDSI and SPI, and checked the applicability of the suggested index in practical drought situation.
