위성기반 Climate Hazards Group InfraRed Precipitation with Station (CHIRPS)를 활용한한반도 지역의 기상학적 가뭄지수 적용 = Application of Meteorological Drought Index using Climate Hazards Group InfraRed Precipitation with Station (CHIRPS) Based on Global Satellite-Assisted Precipitation Products in Korea

다국어 초록 (Multilingual Abstract)

Remote sensing products have long been used to monitor and forecast natural disasters. Satellite-derived rainfall products are becoming more accurateas space and time resolution improve, and are widely used in areas where measurement is difficult because of the periodic accumulation of imagesin large areas. In the case of North Korea, there is a limit to the estimation of precipitation for unmeasured areas due to the limited accessibility andquality of statistical data. CHIRPS (Climate Hazards Group InfraRed Precipitation with Stations) is global satellite-derived rainfall data of 0.05 degreegrid resolution. It has been available since 1981 from USAID (U.S. Agency for International Development), NASA (National Aeronautics and SpaceAdministration), NOAA (National Oceanic and Atmospheric Administration). This study evaluates the applicability of CHIRPS rainfall products forSouth Korea and North Korea by comparing CHIRPS data with ground observation data, and analyzing temporal and spatial drought trends using theStandardized Precipitation Index (SPI), a meteorological drought index available through CHIRPS. The results indicate that the data set performed wellin assessing drought years (1994, 2000, 2015 and 2017). Overall, this study concludes that CHIRPS is a valuable tool for using data to estimateprecipitation and drought monitoring in Korea.
