基于卫星高度计与Argo浮标的海洋涡旋识别数据集
收藏资源简介:
该数据集为2002-2019年全球范围通过高度计获取的海平面高度异常数据识别的涡旋与Argo浮标匹配的涡旋剖面数据集及通过Argo获取的位势密度异常识别的涡旋剖面数据集。其中海面高度数据来自Copernicus Marine Service All-sat merged产品,Argo剖面数据来自法国科里奥利全球数据中心。数据集采用Pickle文件格式,按逐年方式存储,提供全球海域的Argo浮标经纬度、0-1000m位势密度异常以及涡旋信息(涡旋半径、边界、振幅、动能等)等参数。
This dataset contains two types of eddy profile datasets: 1) the eddy profile dataset matched with Argo floats, where eddies are identified using sea level anomaly data collected by satellite altimeters across the global ocean from 2002 to 2019; and 2) the eddy profile dataset identified via potential density anomaly data acquired by Argo floats. The sea level anomaly data is sourced from the Copernicus Marine Service All-sat merged product, while the Argo profile data is obtained from the Coriolis Global Data Assembly Centre in France. Stored in Pickle file format on a yearly basis, this dataset provides parameters including the longitude and latitude of Argo floats in global oceans, potential density anomaly at depths of 0–1000 m, and eddy-related metrics such as eddy radius, boundary, amplitude, kinetic energy, and other relevant indicators.
