Deriving Coastal Sea Surface Current by Integrating a Tide Model and Hourly Ocean Color Satellite Data

Remote Sensing
Sea surface currents (SSCs) play a pivotal role in material transport, energy exchange, and ecosystem dynamics in coastal marine environments. While traditional methods to obtain wide-range SSCs, such as satellite altimetry, often struggle with limited ...

Evaluation of chlorophyll-a algorithms for GOCI and GOCI-II

, 2016
해수로부터 관측되는 파장대별 수출광량(water-leaving radiance)을 이용하여 해수 표층내의 엽록소 농도를 추정하는 알고리즘을 엽록소 알고리즘이라 한다. 대부분의 경험적 엽록소 알고리즘은 엽록소 외의 해수 구성성분에 따라 그 정확도가 크게 변하는데, 우리나라 주변 해역은 용존유기물 및 부유사 농도의 변화가 커서 알고리즘의 정확한 성능 검증 및 고도화가 필요하다.
