祁连山-阿尔金山区站点大到暴雨数据（1961-2020）

本数据集收集了国家气象局提供1961-2020年间祁连山-阿尔金山区13个气象站点的天值数据。在数据集制作过程中，对数据集中的要素数据进行了质量控制，对发现的可疑和错误数据普遍给与了人工核查与更正，并最终对所有要素数据标注质量控制码。处理过程中，基于matlab用算术平均、阈值索引、for循环等方法将各站点的降水数据时间数据提取出来，根据大到暴雨数据定义处理出大到暴雨事件，进而提取出大到暴雨次数、强度、降雨量等信息。本数据时间跨度长，处理结果相对可靠，可应用于青藏高原地区长时间序列的大到暴雨变化特征分析、大到暴雨灾害影响分析等研究之中。

This dataset comprises daily meteorological data from 13 meteorological stations located in the Qilian Mountains-Altun Mountains region, spanning the period from 1961 to 2020, and was provided by the China Meteorological Administration (CMA).
During the dataset development, quality control was performed on all meteorological element data. Detected suspicious and erroneous data were generally manually inspected and corrected, and quality control flags were ultimately assigned to all element data.
In the subsequent processing, temporal precipitation data from each station were extracted using methods such as arithmetic mean, threshold indexing, and for loops implemented in MATLAB. Heavy rain to rainstorm events were identified based on the standardized definition of such precipitation events, and relevant metrics including the frequency, intensity, and total rainfall of these events were subsequently extracted.
This dataset has a long time span and relatively reliable processing results, and can be applied to researches including the analysis of variation characteristics of heavy rain to rainstorm events based on long-time series data and the impact assessment of heavy rain to rainstorm disasters in the Qinghai-Tibet Plateau region.
