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（Automatic Weather Station, AWS）AWS2于2012年8月在厄斯特利恩部署，位置紧邻北极站东侧仅100米处。该站海拔约25米，坐落于坡度平缓的南向坡地，地表覆盖低矮植被/矮灌丛。数据时间戳采用UTC-3时区。该站由两根桅杆组成：一根高3米，搭载东西向伸展的横梁，其上安装各类传感器；另一根高2米，采用涡度协方差技术（Eddy Covariance Technique）测量气体通量（二氧化碳，CO₂）。土壤参数通过两根桅杆附近的剖面钻孔进行测量。AWS2-Meteorology文件包含以下参数：入射与出射短波辐射、入射与出射长波辐射、气温、相对湿度、风速、风向、光合有效辐射（Photosynthetically Active Radiation, PAR）、气压以及反照率（Albedo）。气体通量数据可在通量监测（FluxMonitoring，EC1-GasFlux）文件夹下获取。AWS2相关土壤数据可在土壤（Soil）文件夹下获取，具体包括AWS2-地下温度P1与P2、AWS2-土壤湿度、AWS2-土壤温度、AWS2-地表温度以及AWS2-土壤热通量。AWS2相关积雪数据可在积雪（Snow）文件夹下获取，具体包括AWS2-积雪深度与AWS2-积雪温度。所有数据均以30分钟为间隔进行记录。因该站开展运维作业，2022年9月10日至2022年9月15日期间存在数据缺失；此外，因数据通信故障，2023年4月23日至2023年5月13日期间同样存在数据缺失。
