2003–2010年内蒙古锡林浩特典型草原碳水通量观测数据集

涡度相关技术使精确测定生态系统尺度上的水热通量和CO2通量成为可能，其观测的数据是有关碳水循环模型的开发和验证、精确估算生态系统碳源/汇和水分平衡所需数据的重要来源。本数据集为中国通量观测联盟（ChinaFLUX）首批观测点内蒙古站（位于中国科学院内蒙古草原生态系统定位研究站1979年围封样地）的生态系统通量观测数据。本数据集严格遵循ChinaFLUX标准化的生态系统碳水通量和关键气象数据质量控制和规范体系而形成，包括半小时、日尺度、月尺度和年尺度4个碳/水通量和气象数据产品表格，其中碳/水通量数据半小时数据集包含缺失数据插补前和插补后两类。数据集的指标包含生态系统CO2通量、潜热通量、显热通量、空气温度、土壤温度、土壤湿度、降水、总辐射和光合有效辐射。本数据集的详细说明信息可访问 http://www.csdata.org/p/443/ 了解。

The Eddy Covariance technique enables the accurate measurement of water, heat and CO₂ fluxes at the ecosystem scale. The observational data obtained via this technique serve as a critical source for developing and validating carbon-water cycle models, as well as for precisely estimating ecosystem carbon source/sink and water balance. This dataset comprises ecosystem flux observational data from the Inner Mongolia Site, one of the first observation stations of the ChinaFLUX (China Flux Observation Network). The Inner Mongolia Site is located within the 1979 fenced plot of the Inner Mongolia Grassland Ecosystem Research Station of the Chinese Academy of Sciences. This dataset was developed strictly in accordance with the standardized quality control and specification system for ecosystem carbon-water fluxes and key meteorological data established by ChinaFLUX. It includes four types of data product tables for carbon/water fluxes and meteorological data at half-hourly, daily, monthly and annual scales. Notably, the half-hourly carbon/water flux dataset contains two subsets: data before missing data imputation and data after missing data imputation. The dataset covers the following variables: ecosystem CO₂ flux, latent heat flux, sensible heat flux, air temperature, soil temperature, soil moisture, precipitation, total solar radiation, and photosynthetically active radiation (PAR).
