2005～2014年CERN野外台站气象观测场土壤含水量数据集
A soil moisture dataset observed in weather sites of CERN(2005-2014)
【摘要】 土壤水分是影响陆地–大气边界层能量和物质传输的重要因子。土壤水分含量是中国生态系统研究网络（CERN）陆地生态系统水环境长期定位观测的重要指标。截至2014年，CERN全国范围内包括农田、森林、草地、荒漠与湿地等生态类型的34个陆地生态系统台站，依据陆地水环境观测规范、质量保证与质量控制规范，设立观测样地，并开展土壤含水量的长期定位观测与数据汇交及质控工作。CERN水分分中心选取了这34个台站2005～2014年气象观测场的土壤含水量长期监测数据，通过进一步统一规范数据格式，形成了全国范围内较长时间序列的公开共享数据集，为土壤含水量时空动态的遥感反演、模型估算验证提供地面实测数据支撑。
【Abstract】 Soil moisture is an important variable that influences land-atmosphere interactions by modifying energy and water fluxes in the boundary layer. It is one of the most important variables long-term monitored by Chinese Ecosystem Research Network(CERN). The soil moisture in-situ monitoring instruments have been set up in CERN’s 34 stations of various terrestrial ecosystems according to the CERN’s protocols of observation and quality control. The dataset contains soil moisture documented in weather sites from the 34 stations across China, during 2005 and 2014. The raw data have been processed through basic quality control approaches and general format translation. This time-series dataset can provide a general profile of, and spatial and temporal dynamics of soil moisture over China since 2005. It can also be used for calibrating and validating of remote sensing retrieval or model simulation.
