全球均一化地表风速数据集（1973-2022）

本数据集包括1973 - 2022年全球3600多个站点的地表风速以及他们对应的均一化数据。地转风反映了仅在大气环流影响下的风速，因此本数据集以地转风为参考序列，结合RHtests中惩罚极大t检验，对原始观测风速进行了均一化检验及订正。结果表明，全球有35.0%的台站地表风速存在不均一性问题。地表风速的均一化对全球地表风速趋势的影响较小，但对评估区域趋势，特别是欧洲、亚洲和大洋洲的区域趋势影响较大。

This dataset contains surface wind speed data and their corresponding homogenized records from over 3,600 global stations spanning 1973 to 2022. Geostrophic wind represents wind speed driven solely by atmospheric circulation. Therefore, this dataset adopted geostrophic wind as the reference series, combined with the penalized maximum t-test from RHtests, to perform homogenization tests and corrections on the original observed surface wind speed data. The results indicate that 35.0% of the global stations have inhomogeneity issues in their surface wind speed records. Homogenization of surface wind speed exerts relatively minor impacts on global surface wind speed trends, but exerts a more substantial influence on the assessment of regional trends, especially those in Europe, Asia, and Oceania.
