| Abstract: |
| The drift sea-air interface buoy is an innovative "small, light, and maintenance-free" drifting observation. It can measure 11 different physical parameters, including 3-m weather above the sea surface, sea surface temperature 20 cm below water surface), and wave parameters, and has been used for many times with good result. To promote the global application of the observation data by floating air-sea interface buoy, based on the sea surface temperature observed by Argo, SVP buoy, and OISST data of the Kuroshio extension sea area in 2018, the sea surface temperature observed by the drifting air-sea interface buoy developed independently in China was evaluated systematically and its observation accuracy in the complex hydrological environment of the Kuroshio extension areas was tested. Result show that that correlation coefficient between SST data observed by drift sea-air interface buoy and that observed by Argo was 0.973 7, and the root mean square error and average error were 0.579 0℃ and 0.453 9℃, respectively. The correlation coefficient with SVP buoy SST data was smaller than that with Argo, which is 0.928 5, the root mean square error was 1.323 0℃, and the average error was about 0.979 4℃. The correlation coefficient with OISST data was 0.982 3, the root mean square error was 0.798 8℃, and the average error was 0.743 4℃. The SST data observed by drifting sea-air interface buoy are in good agreement with those observed by Argo, SVP, and OISST, and the quality of the observed data is at the same level. Therefore, as a new observation method, drifting sea-air interface buoy has the ability to accurately observe SST. |
