North American proxy records of near-surface wind direction from the LGM and deglaciation

This dataset is the accompanying file for Table 1 in Conroy et al. (2025). It includes North American proxy records of near-surface wind direction from the LGM and deglaciation. Sites and samples therein are organized in grids of 0.5 degree latitude × 0.5 degree longitude. Archive type abbreviations are as follows: LP = loess particle size trends, LT = loess thickness patterns, LC = loess chemistry, Dr =wind-aligned drainages, D = dune orientation, S = lacustrine spits, SaSt = sand stringers. Zonal wind direction indicates whether interpreted wind direction is westerly or easterly. Meridional wind direction indicates whether interpreted wind direction is northerly or southerly. A confidence level of 1 indicates more precise chronology and/or wind-direction information, whereas level 2 indicates more uncertainty in chronology and/or inferred wind direction. ‘Secondary’ references are previously published syntheses that included these wind-direction data.本数据集为Conroy等（2025）研究中表1的配套文件。数据集收录了末次冰盛期（Last Glacial Maximum，LGM）与冰消期的北美近地表风向代用记录。所有采样点与样本均按0.5°纬度×0.5°经度的网格进行组织。存档类型缩写说明如下：LP为黄土粒径趋势（loess particle size trends），LT为黄土厚度展布模式（loess thickness patterns），LC为黄土地球化学特征（loess chemistry），Dr为风成顺向排水道（wind-aligned drainages），D为沙丘走向（dune orientation），S为湖岸沙嘴（lacustrine spits），SaSt为砂质条带（sand stringers）。纬向风向指解译所得风向为西风或东风；经向风向指解译所得风向为北风或南风。置信等级1代表年代学及/或风向信息精度更高，而等级2则代表年代学及/或推断风向的不确定性更强。‘二级参考文献’指此前已发表的、包含此类风向数据的综合研究成果。
