基于Argo浮标和EOF建立区域海水三维声速场的方法

Modeling three-dimensional acoustic field in the ocean by using Argo and EOF

本文提出了一种利用Argo浮标数据和经验正交函数(EOF)建立区域海水三维声速场的方法。利用局部区域内的Argo观测数据对该方法进行了验证,利用少量Argo浮标数据即可建立精度较高的三维海水声速场模型,预测区域内任意剖面的中误差在1 m/s左右。

The method for modeling three-dimensional acoustic field in the ocean by using ARGO observations and EOF was proposed in this paper. The ARGO observations were used to fit profiles of acoustic speed in a local area by using EOF and spherical harmonic functions, the fitting results were compared to the observations from the ARGO not used in the modeling. Using only a few Argo buoys data an accuracy of 1 m/s could be achieved.
