A dataset of carbon and water fluxes of the temperate desert steppe in Damao Banner, Inner Mongolia (2015–2018)

Eddy correlation technology is an important observation method for the precise and long-term continuous measurement of carbon-water flux in ecosystems. The observations can provide important data support for studying carbon and water cycle processes and mechanisms in terrestrial ecosystems and evaluating ecosystem carbon income and expenditure. Damao Desert Steppe Station (Damao Station) is one of the member stations of the Chinese FLUX Observation and Research Network, located in Baotou City, central Inner Mongolia Autonomous Region. The vegetation in the station area is a typical example of warm desert grassland in China, primarily composed of needlegrass communities. Based on the eddy covariance method, Damao station has been carrying out integrated observations of ecosystem carbon and water fluxes for a long term. This dataset compiles the observation data from Damao Station from 2015 to 2018 pursuant to the strict data processing system of ChinaFLUX. It is a standardized dataset of ecosystem CO2 flux, water and heat flux, and corresponding meteorological elements, including the data products at half-hourly, daily, monthly, and yearly scales.

涡度相关技术（Eddy correlation）是用于精准、长期连续监测生态系统碳-水通量的重要观测手段。该观测数据可为研究陆地生态系统碳水循环过程与机制、评估生态系统碳收支提供重要的数据支撑。达茂荒漠草原站（Damao Desert Steppe Station，简称达茂站）是中国通量观测研究网络（ChinaFLUX）的成员站之一，坐落于内蒙古自治区中部包头市。站点区域植被为我国典型的暖温带荒漠草原，以针茅群落为主要构成。基于涡度协方差方法，达茂站长期开展生态系统碳-水通量的综合观测。本数据集依据ChinaFLUX严格的数据处理体系，整合了达茂站2015年至2018年的观测数据，是一套标准化的生态系统CO₂通量、水热通量及对应气象要素数据集，包含半小时、日、月、年尺度的数据产品。
