AWS2-Meteorology

The automatic weather station AWS2 was installed in August 2012 in Østerlien just 100 meter east of Arctic Station. The station is located approximately 25 meter above sea level in a gentle south sloping area covered by low vegetation/dwarf shrubs. The time stamp refer to UTC-3. The station consist of a 3 meter high mast with an east west pointing cross beam where sensors are mounted, and a 2 meter high mast where gasfluxes (CO2) are measured using eddy covariance technique. Soil parameters are measured in profiles and boreholes adjacent to the two masts. The AWS2-Meteorology file holds the following parameters (Shortwave radiation in and out, Longwave radiation in and out, Air temperature, Relative humidity, Wind speed, Wind direction, PAR, Air pressure and Albedo). Find gasflux data under FluxMonitoring (EC1-GasFlux). Find soil data from AWS2 under Soil (AWS2-GroundTemperatureP1 and P2, AWS2-SoilMoisture, AWS2-SoilTemperature, AWS2-SurfaceTemperature, AWS2-SoilHeatFlux). Find snow data from AWS2 under Snow (AWS2-SnowDepth, AWS2-SnowTemperature). All data are logged by 30-minute intervals. There is a gap in data from 10 September 2022 to 15 September 2022 due to service and maintenance of the station. There is also a gap from 23 April 2023 to 13 May 2023 due to a failure in the data communication.

自动气象站AWS2于2012年8月在厄斯特利恩（Østerlien）部署，地处北极站（Arctic Station）东侧仅100米处。该站点海拔约25米，坐落于坡度平缓的南向区域，地表覆盖低矮植被与矮灌丛。时间戳采用协调世界时减3小时（UTC-3）时区。该站点由两座桅杆组成：一座高3米，搭载东西向指向的横梁及各类传感器；另一座高2米，采用涡度协方差技术测量气体通量（二氧化碳，CO₂）。土壤参数通过两座桅杆附近的剖面钻孔进行监测。AWS2-气象数据文件包含以下参数：入射短波辐射、出射短波辐射、入射长波辐射、出射长波辐射、气温、相对湿度、风速、风向、光合有效辐射（Photosynthetically Active Radiation，PAR）、气压及反照率。气体通量数据可于FluxMonitoring（EC1-GasFlux）目录下调取。AWS2的土壤数据可在Soil目录下获取，具体包含：AWS2-地下温度P1与P2、AWS2-土壤含水量、AWS2-土壤温度、AWS2-地表温度及AWS2-土壤热通量。AWS2的积雪数据可在Snow目录下获取，具体包含：AWS2-积雪深度与AWS2-积雪温度。所有数据的采样间隔为30分钟。2022年9月10日至2022年9月15日期间，因站点运维工作出现数据断档。2023年4月23日至2023年5月13日期间，因数据通信故障出现数据断档。
