亚洲中部干旱区全新世水文气候突变特征集成数据集（距今11700年至今）

收集整理了亚洲中部干旱区全新世降水/湿度记录资料，从中筛选出分辨率高于50年、测年点多于每千年1个、明确指示降水/湿度变化等优点的高质量记录共9条。通过数学方法将原始序列按照平均分辨率插值后，利用带通滤波方式，去除低频（1/2000a）和高频（1/400a）信号，将获得的结果进行Z值标准化。以1倍标准差作为界定气候突变的依据，集成得到研究区全新世干-湿气候事件的时空特征。

We compiled and curated a dataset of Holocene precipitation and humidity proxy records from the arid central Asia. A total of 9 high-quality records were selected, which meet the following screening criteria: temporal resolution higher than 50 years, dating control density of more than one point per millennium, and explicit indication of precipitation/humidity variations.
First, the original proxy sequences were interpolated to the uniform average resolution using mathematical methods. Thereafter, a band-pass filter was employed to remove low-frequency signals (period > 2000 a, equivalent to 1/2000 a⁻¹) and high-frequency signals (period < 40 a, equivalent to 1/40 a⁻¹). The resulting filtered data were then standardized via Z-score normalization.
Using one standard deviation as the threshold for defining abrupt climate events, we integrated the processed datasets to reconstruct the spatiotemporal characteristics of Holocene dry-wet climate events in the study area.
