摘要:
漂流式海气界面浮标是创新研制的"小型化、轻质化、免维护"的漂流观测系统, 能够测量海面以上3 m气象、水下20 cm海表面温度和波浪参数等11个不同的物理参数, 并且已经经过多次观测应用, 结果均较好。为实现漂流式海气界面浮标观测数据全球范围的应用, 利用2018年黑潮延伸体海域Argo观测的海表面温度(sea surface temperature, SST)、SVP (surface velocity program)浮标观测的海表温度和OISST (optimum interpolation sea surface temperature)数据, 通过将其与漂流式海气界面浮标观测数据进行时空匹配以及对比验证, 对漂流式海气界面浮标观测的海表面温度进行了系统评估, 检验其在黑潮延伸体复杂水文环境下的观测准确性。结果表明, 漂流式海气界面浮标观测SST数据与Argo观测SST数据相关系数达到0.973 7, 均方根误差和平均误差分别为0.579 0℃和0.453 9℃; 与SVP浮标SST数据的相关系数弱于与Argo的相关系数, 为0.928 5, 均方根误差为1.323 0℃, 平均误差约为0.979 4℃; 与OISST数据的相关系数为0.982 3, 均方根误差为0.798 8℃, 平均误差为0.743 4℃。漂流式海气界面浮标观测SST数据与Argo、SVP和OISST海表面温度数据都具有很好的一致性, 观测数据质量处于同一水平。综上, 漂流式海气界面浮标作为一种新的观测手段, 具备了准确观测SST的能力。

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.
