EFAR dataset

Based on sea surface temperature (SST) and sea level anomaly (SLA) data, the eddy-front associations are reasonably classified into three categories according to their topological structure, which are weak association, medium association and strong association. The eddy-front association recognition network (EFARN) is used to obtain the recognized fronts, the mask of eddy-front categories and three types of eddy-front associations.本数据集以海表温度（SST）与海平面异常（SLA）数据为基础，依据拓扑结构将涡旋-锋面关联（eddy-front associations）合理划分为弱关联、中等关联与强关联三类。借助涡旋-锋面关联识别网络（eddy-front association recognition network, EFARN），可获取已识别锋面、涡旋-锋面类别掩码以及三类涡旋-锋面关联数据。
