基于Argo浮标剖面数据获取全球海面温度异常

A New Method to Obtain Global Sea Surface Temperature Anomaly Using Argo Profiling Data

Argo浮标的大范围投放,为海洋科学研究提供了丰富的资料,使得海洋表层温度的获取不再局限于传统的考察船、漂流浮标和卫星数据反演。本文提出了获取海洋表层温度的一种新方法。利用Argo浮标实测剖面数据与标准温度模型,获取每个格网点的温度异常;然后再利用标准温度模型和温度异常,获取海洋表面上任一点的温度。利用实测数据对此方法进行验证,得到内符合精度为1.8,外符合精度为1.97,结果证明了此方法的可行性和有效性。

Wide delivery of Argo floats provides rich materials for marine scientific research,and makes sea surface temperature acquisition modes no longer confined to the traditional ways,such as survey ships,drifting buoys and satellite data inversion.A new method to obtain the ocean surface temperature is proposed in this paper.By using Argo profiling data and the standard temperature model,the temperature anomaly of every grid can be firstly obtained.Then,the sea surface temperature at any point is obtained by using the temperature anomaly and standard temperature model.The validation is made by using the profiling data,achieving the standard deviation of inner error 1.8 and external error 1.97 and turning out the feasibility and efficiency of this method.
