Automatic Weather Station Data obtained at Dome A (Argus), Antarctica

Automatic Weather Station data obtained at Dome A (Argus), Antarctica.Data from this AWS are currently available from 2005-2017. At this stage the AWS remains operational, and the data record will be updated as data become available. The surface elevation of Dome Argus (Dome A) is 4093 m, i.e., at one of the highest place in Antarctica. Our Automatic Weather Station has been deployed near one end of an elongated ridge (about 60 km long and 10 km wide). At this location the thickness of the glacial ice sheet is in excess of 3000 m, overlaying the subglacial Gamburtsev Mountains. We consider this location as a potential site to collect an ice core to provide a record of past climate and atmospheric gas composition going back more than one million years.The Dome A AWS measures:- 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.
