A dataset of carbon and water fluxes of the grassland ecosystem at Arou Station from 2013 to 2024

This dataset includes the flux observation data of the Arou grassland ecosystem from 2013 to 2024. The raw observation data were collected in the A'rou freeze/thaw observation station, a alpine grassland ecosystem flux observe site. The site is located in Arou Township, Qilian County, Qinghai Province. We processed the raw observation data based on the ChinaFLUX data processing specifications to produce this standardized dataset of ecosystem carbon and water fluxes and key meteorological elements. In this dataset, the annual data consists of eight Excel data files, divided into two categories: LITE, which includes the main fluxes and meteorological variables, and ALL, which adds data quality and interpolation indicators on top of LITE. Each category has four data files, including data files at four scales: half-hour (HH), day (DD), month (MM), and year (YY).

本数据集涵盖2013年至2024年的阿柔草原生态系统通量观测数据。原始观测数据采集于阿柔冻融观测站，该站点为高寒草原生态系统通量观测场，坐落于青海省祁连县阿柔乡。本数据集依据中国陆地生态系统通量观测研究网络（ChinaFLUX）的数据处理规范对原始观测数据进行加工处理，生成了包含生态系统碳、水通量及关键气象要素的标准化数据集。本数据集的年度数据包含8个Excel数据文件，分为两类：LITE类涵盖主要通量与气象变量，ALL类则在LITE类的基础上新增了数据质量与插值指标；每类各包含4个数据文件，分别对应4种时间尺度：半小时（HH）、日（DD）、月（MM）以及年（YY）。
