Automatic Weather Station Data obtained at traverse site 69 along the Lambert Glacier Basin, Antarctica, 2002-2008

Automatic Weather Station data obtained at traverse site 69 along the Lambert Glacier Basin, Antarctica.Data from this AWS are available intermittently, with (i) the first installation LGB69 from 22 January 2002 to 02 February 2007 and (ii) the 2nd installation LGB69-A 02 February 2007 to 20 August 2008. Together 2002 to 2009 encapsulates the full operational lifetime of AWS instrumentation at this location.

Together 2002 to 2009 encapsulates the full operational lifetime of AWS instrumentation at this location. LGB69 had been deployed at 70.835277^oS and 77.074722^oE, moving slowly downslope. The surface elevation of the AWS site LGB69 was 1850 m, while that of LGB6-A was 1854m. The LGB69 AWSes measured:- wind speed (knots)- air temperature - with sensors mounted on mast arms at 1 m, 2 m and 4 m above the snow surface (degrees Celsius) - snow temperature at 0.1 m, 1 m, 3 m and 10 m depth- atmospheric pressure (hPa)- wind direction (degrees)- incoming solar radiation (MJ per square metre)- relative humidity (percent)- snow-fall rate.(We note that sensor heights decrease as precipitation settles at the site.)Time is given in UTC.

本数据集为南极洲兰伯特冰川盆地69号考察站点的自动气象站（Automatic Weather Station, AWS）观测数据。该AWS的观测数据为间断式发布，其中（i）第一代部署设备LGB69的观测时段为2002年1月22日至2007年2月2日；（ii）第二代部署设备LGB69-A的观测时段为2007年2月2日至2008年8月20日。该站点AWS设备的完整运行周期为2002年至2009年。LGB69的部署坐标为南纬70.835277°、东经77.074722°，设备随冰盖缓慢向下坡移动。LGB69对应站点的地表海拔为1850米，LGB69-A对应站点的地表海拔为1854米。本批次LGB69系列AWS的观测要素包括：
- 风速（单位：节）
- 气温：传感器分别安装于雪面上方1米、2米及4米的桅杆臂上，单位为摄氏度（℃）
- 积雪温度：分别测量0.1米、1米、3米及10米深度处的积雪温度
- 大气压强（单位：百帕，hPa）
- 风向（单位：度）
- 入射太阳辐射（单位：兆焦每平方米，MJ/m²）
- 相对湿度（单位：百分比，%）
- 降雪速率
注：由于该站点积雪沉降，传感器的实际安装高度会随时间降低。时间采用协调世界时（UTC）标注。
