", "ds_quality": "首先获取各气象站的自动观测及人工观测原始数据，之后进行质量控制。
\n数据质量控制阶段分为两步：首先数据提供者对数据进行了完整性、准确性检查。数据完整性检查主要检查各站点数据的时间范围和观测字段是否达到项目要求。数据准确性检查一方面通过数值图示，通过人工经验判断异常值并进行剔除，另一方面对数据的存储方式、格式进行统一与规范。第二阶段是不同数据提供者对其它数据进行交叉检查，再次审核数据的完整性和准确性，并对不同区域的数据进行整合。其中，数据质量控制过程中生成的数据自检表及数据分析图一并存于数据文件夹中。
\n最后整合各气象站的数据，得到完整、准确、格式一致的普通站雪深数据集。

\r\nThe data quality control stage is divided into two steps: First, the data provider checks the integrity and accuracy of the data. The data integrity check mainly checks whether the time range and observation fields of the data at each station meet the project requirements. On the one hand, the data accuracy check determines and eliminates abnormal values through numerical illustration and manual experience. On the other hand, the data storage method and format are unified and standardized. The second stage is for different data providers to cross-check other data, review the integrity and accuracy of the data again, and integrate data from different regions. Among them, the data self-test table and data analysis chart generated during the data quality control process are stored in the data folder.
\r\nFinally, the data from various meteorological stations are integrated to obtain a complete, accurate and consistent format snow depth data set at ordinary stations.
