The terrestrial evapotranspiration (ET) is the sum of evaporation from soil surface and transpiration from vegetation. It is a fundamental component to understand the land surface water cycle and the energy interaction between land surface and atmosphere. Thus, the quantification of ET is important to improve our understandings such as the terrestrial water budget as well as water management. Accurate estimation of ET is very difficult due to complex interactions between atmosphere-vegetation-soil. There are lots of flux tower measurements sites to monitor ET variations for various biome types in Northeast Asia. Numerous studies to monitor ET have been conducted, though the regional scale studies on ET are still few in Northeast Asia. Satellite remote sensing technique provides an opportunity to estimate ET at the large scale area. In this study, therefore, we present the methodology for estimating ET based on the satellite remotely sensed data under clear and cloudy sky conditions in Northeast Asia. Various atmosphere and land products produced from the Moderate Resolution Imaging Spectroradiometer (MODIS) were used to estimate ET. However, frequent cloud cover results in a substantial loss of remote sensing information, limiting the capability of continuous ET monitoring for the monsoon region such as the Northeast Asia. For this reason, the gap-filling processes were conducted for meteorological and land surface variables. The missing data for the temperature variables derived from MODIS products was filled by integrating the brightness temperature produced from the Advanced Microwave Scanning Radiometer-Earth Observing Syst ... 전체 초록 보기
