黑河综合遥感联合试验：大野口关滩森林站自动气象站数据集

该数据集包含了大野口关滩森林站的自动气象站观测数据，站点位于甘肃省张掖市南部的大野口关滩。观测点的经纬度为100°15′E，38°32′N，海拔高度为2835m。观测场处在黑河上游大野口子流域关滩阴坡的森林内，林内主要是高约15-20m的云杉，地面覆盖有厚约10cm的苔藓，植被生长情况良好。
观测项目有：大气风温湿梯度观测（2m和10m）、气压、雨雪量计、雪深、光合作用有效辐射、两层辐射四分量（1.68m和19.75m）、树干液流、地表温度、多层土壤温度（5cm、10cm、20cm、40cm、80cm和120cm）、土壤水分（5cm、10cm、20cm、40cm、80cm和120cm）及土壤热通量（5cm和15cm）。
数据观测时段为2007年10月1日至2011年11月30日。详细信息请参见下面“其他在线资源”中的“气象水文通量数据使用指南”。

This dataset contains automatic meteorological station observation data collected at the Dayekou Guantan Forest Station, which is located in Dayekou Guantan, south of Zhangye City, Gansu Province, China. The observation site is situated at 100°15′E, 38°32′N, with an elevation of 2835 m. The observation plot is located within a forest on the shady slope of Guantan in the Dayekouzi watershed, upper reaches of the Heihe River. The forest is dominated by spruce trees with a height of approximately 15–20 m, and the ground is covered by approximately 10 cm thick moss, with well-established vegetation.
Observation items include: gradient measurements of atmospheric wind speed, temperature and humidity at 2 m and 10 m; atmospheric pressure; rain-snow gauge; snow depth; photosynthetically active radiation (PAR); four-component radiation measurements at two heights (1.68 m and 19.75 m); stem sap flow; surface soil temperature; multi-layer soil temperatures at depths of 5 cm, 10 cm, 20 cm, 40 cm, 80 cm and 120 cm; soil moisture at the same six depths as the soil temperature sensors; and soil heat flux at 5 cm and 15 cm.
The data collection period spans from October 1, 2007 to November 30, 2011. For detailed information, please refer to the "Meteorological and Hydrological Flux Data Usage Guide" under the "Other Online Resources" section below.
