Estimation of Spatial Evapotranspiration of Korean Peninsula using NOAA/AVHRR Satellite Images

NOAA/AVHRR 위성영상을 이용한 한반도 증발산량 산정

The purpose of this study is to estimate monthly evapotranspiration (ET) using normalized difference vegetation index (NDVI) from NOAA/AVHRR Korea peninsula images. Morton actual ET for land surface conditions was evaluated by using 73 daily meteorological data, and the monthly averaged Morton ETs for each land cover were compared with the monthly maximum NDVIs of a year, 2001. There was a high correlation between monthly maximum NDVI and monthly averaged Morton ET. It was concluded that the monthly ET can be estimated from the NDVI information of NOAA/AVHRR.
