한반도 연안에서의 12.5 km 해상도 QuikSCAT 해상풍 검증 = Validation of QuikSCAT Wind with Resolution of 12.5 km in the Vicinity of Korean Peninsula

다국어 초록 (Multilingual Abstract)

Several validation studies have been made for QuikSCAT(QSCAT) wind data around the world, mainly in the offshore. However, until now, there were no validation studies for QSCAT wind with resolution of 12.5 km (‘QSCAT 12.5 km wind’) in the vicinity of Korean Peninsula. To validate ‘QSCAT 12.5 km wind’ and to investigate its characteristics around Korean Peninsula, the wind data from Ieodo
Ocean Research Station, KMA buoys, and KORDI Realtime Observation Stations have been compared.
Validation results showed that ‘QSCAT 12.5 km wind’ RMSE of wind direction and speed were 25.85o and
1.83 m/s, respectively, at Ieodo Station. The mean wind speed correlation coefficient of KMA buoys and KORDI Realtime Observation Station were 0.78 and 0.61, and the mean wind speed RMSE were 2.2 m/s and 3.2 m/s, respectively. This seems to be mainly because of the distance between QSCAT and in-situ
observation stations. The RMSE of wind direction were bigger than 40o at all in-situ observation stations
located near the shore, within 20 km from coastlines. Geophysical features where in-situ observation
stations are located seem to affect wind validation scores.
