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