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 West Greenland Standard Time (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）建成，其位置紧邻北极站东侧仅100米处。该站海拔约25米，地处坡度平缓的南向坡地，地表覆盖低矮植被与矮灌丛。所有时间戳均采用西格陵兰标准时间（UTC-3）。该站由两座桅杆组成：一座高3米，带有东西向指向的横梁，用于安装各类传感器；另一座高2米，采用涡度协方差（eddy covariance）技术测量二氧化碳（CO₂）气体通量。两座桅杆周边的土壤剖面与钻孔内布设了土壤参数监测装置。AWS2-气象数据集文件包含以下监测参数：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（PAR）、气压及反照率。气体通量数据可于通量监测（FluxMonitoring，EC1-GasFlux）项下查询。AWS2的土壤数据可于土壤（Soil）模块下查询，具体包含AWS2-地面温度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的积雪数据可于积雪（Snow）模块下查询，具体包含AWS2-积雪深度与AWS2-积雪温度。所有数据均以30分钟为采样间隔进行记录。该数据集存在两段数据缺失时段：2022年9月10日至2022年9月15日，因站点运维检修所致；2023年4月23日至2023年5月13日，因数据通信故障所致。
