Abstract
Ocean surface wind speed was estimated using TRMM (Tropical Rainfall Measurement Mission) TMI (TRMM Microwave/Imager) data. It is used the TRMM TMI brightness temperature and National Data Buoy Center's buoy winds speed dataset near North-America to estimate by the algorithm of the ocean surface wind speed retrieval over North America. Comparing with the buoy data by D-matrix equation, the result that RMSE, BIAS, and correlation coefficient are 2.19
본 연구에서는 열대강우관측 위성(TRMM) 자료를 이용하여 해상풍을 예측하였고, TRMM TMI 휘도 온도와 북미 주변의 NDBC (National Data Buoy Centers) 부이 자료를 이용하여 해상풍을 추정하였다. 이 결과는 행렬방정식에 의한 부이와 비교하였는데 RMSE, BIAS 그리고 상관계수는 각각 2.19
