北极3h海冰高频速度场分析数据(1979-2019年)
收藏资源简介:
本数据基于国际北极漂移浮标计划(IABP)的海冰GPS信息(1979-2019),完成了海冰高频速度场的计算及标准化处理,形成有效数据文件2194套,超过270万个数据点。IABP浮标被固定在海冰上随冰一起运动,浮标位置的变化即可表示海冰的运动轨迹,相应的水平位置信息通过Argos或GPS卫星系统传输和收集,两种定位方式的地理精度分别为300 m、100 m。
This dataset is constructed using sea ice GPS observations (1979–2019) sourced from the International Arctic Buoy Program (IABP). High-frequency sea ice velocity fields were computed and standardized, yielding 2194 valid data files comprising over 2.7 million data points. IABP buoys are affixed to sea ice and drift along with the ice pack; changes in the buoys' positional coordinates directly reflect the movement trajectories of the sea ice. The associated horizontal position data are transmitted and collected via either the Argos or GPS satellite systems, with respective geographic positioning accuracies of 300 m and 100 m for the two positioning methods.
