Abstract

In this study, temporal variations of the Advanced Microwave Scanning Radiometer E (AMSR-E) soil moisture products were evaluated using ground based measurements from the Haenam flux monitoring network site for two years (2004 and 2006). Even if there were major comparison issues including spatial resolutions, AMSR-E soil moisture production showed a great potential to replicate temporal variability patterns with ground based measurements. Additional intensive validation efforts should be conducted at a variety of field conditions including vegetation type for better utilization of remotely sensed soil moisture and understanding of the land surface-atmosphere interactions in the view of hydrometeorology.

본 연구에서는 원격탐사자료인 Advanced Microwave Scanning Radiometer E (AMSR-E) 토양수분자료의 시간적 변통성 검증을 위해 해남 플럭스 지점에서 관측된 2년간의 (2004년과 2006년) 토양수분자료를 이용하였다. 지상관측 토양수분자료에 비해 상대적으로 큰 공간해상도를 가진 원격탐사자료(AMSR-E)는 2년간의 비교/검증에서 지상관측토양수분자료와 시간적 상관성이 있는 것으로 파악되었으며, 차후에 보다 다양한 식생조건과 현장조건에서 심도 있는 검증연구가 이루어져야 할 것으로 판단된다. 이를 위해서는 보다 다양한 지역에서 현장측정이 이루어져야할 것으로 사료된다. 이를 통하여 보다 정확한 비교/검증 연구가 수행된다면, 원격탐사 토양수분자료의 활용성을 기대할 수 있으며 또한 수문기상학적 관점에서 지표면 대기의 상호작용에 대한 올바른 이해를 향상시킬 수 있을 것으로 판단된다.
