Absolute Geostrophic Velocity Inverted from the Environmental Working Group (EWG) Joint U.S.-Russian Atlas of the Arctic Ocean with the P-Vector Method (NCEI Accession 0156424)

The dataset (called EWG-V) comprises 3D gridded climatological fields of absolute geostrophic velocity inverted from the Environmental Working Group (EWG) Joint U.S.-Russian Atlas of the Arctic Ocean using the P-vector method. It provides a climatological velocity field that is dynamically compatible to the EWG (T, S) fields. The EWG-V velocity fields have the annual, and seasonal (winter and summer) means with the same horizontal resolution of 25 km and 90 vertical levels as the EWG temperature and salinity fields.

本数据集命名为EWG-V，包含通过P矢量法（P-vector method）从环境工作组（Environmental Working Group，EWG）美俄联合北冰洋图集反演得到的绝对地转流速三维网格化气候场。该数据集提供与EWG温盐（T, S）场动力适配的气候流速场。EWG-V流速场涵盖年平均与季节（冬季、夏季）平均数据，其水平分辨率为25千米，垂直层数为90层，与EWG温度和盐度场保持一致。
