Surface meteorological data from a network of automatic weather stations at a number of Antarctic sites and sub-Antarctic sites 1982-2022 data

Surface meteorological data are provided from a network of Automatic Weather Stations (AWS) at 20 sites in remote regions of East Antarctica, and one at sub-Antarctic Heard Island. These stations are deployed and operated by the Australian Antarctic Division Glaciology Program. The first station was deployed in 1982 and the network has continued to expand since then.All stations use the ARGOS data relay system, carried by the NOAA series of near-polar orbiting satellites to relay data. Three-hourly synoptic data from most AWS are distributed in near real time directly by Service Argos via the World Meteorological Organisation, Global Telecommunication System. The data set described here contains the climatic record of all observations from the stations. It is not a real-time data set.All stations measure air temperature, atmospheric pressure, wind speed and direction. Most measure air temperature and wind speed at more than one height, providing data on near-surface vertical gradients, a check on the data accuracy, and some instrumental redundancy. Some stations have additional sensors measuring snow temperature at different depths, atmospheric humidity, solar radiation and height of the sensors above the snow surface (which changes due to snow accumulation and ablation) as well as several 'house-keeping' parameters (voltage, internal temperature, etc.).While the data are hosted on a site separate to the Australian Antarctic Data Centre, a copy of the 1982-2022 data has been made and is attached to this metadata record, and is citable via the provided DOI.To access the previous copy of the data (1982-2011), which also included some summary graphs, and earlier versions of the associated pdf files of information, please contact the AADC.2022 Data UpdateA028, located at 68°24'28''S 112°13'03''E, elevation 1622m above sea level.
