TY - Data T1 - Heihe River Integrated Remote Sensing joint experiment: data set of automatic weather station of Dayekou guantan forest station (2007-2011) A1 - Huang huanghui A1 - Ma mingguo A1 - Wang weizhen A1 - Tan Junlei DO - 10.12072/ncdc.NIEER.db1827.2022 PY - 2022 DA - 2022-03-14 PB - National Cryosphere Desert Data Center AB - The data set contains the observation data of automatic weather station of Dayekou guantan forest station, which is located in Dayekou guantan in the south of Zhangye City, Gansu Province. The longitude and latitude of the observation point are 100 ° 15 ′ e, 38 ° 32 ′ n, and the altitude is 2835m. The observation site is located in the forest on the shady slope of guantan in dayekouzi watershed in the upper reaches of Heihe River. The forest is mainly spruce with a height of about 15-20m, the ground is covered with moss with a thickness of about 10cm, and the vegetation growth is good. Observation items include: atmospheric wind temperature and humidity gradient observation (2m and 10m), air pressure, rain and snow gauge, snow depth, photosynthetic effective radiation, four components of two-layer radiation (1.68m and 19.75m), trunk sap flow, surface temperature, multi-layer soil temperature (5cm, 10cm, 20cm, 40cm, 80cm and 120cm), soil moisture (5cm, 10cm, 20cm, 40cm 80cm and 120cm) and soil heat flux (5cm and 15cm). The data observation period is from October 1, 2007 to November 30, 2011.
