The Antarctic Automatic Weather Station (AAWS) network, first commenced in 1978, is the most extensive ground meteorological network in the Antarctic, approaching its 30th year at several of its installations. Its prime focus as a long term observational record is to measure the near surface weather and climatology of the Antarctic atmosphere. AWS sites measure air-temperature, pressure, wind speed and direction at a nominal surface height of 3m. Other parameters such as relative humidity and snow accumulation may also be measured. Observational data from the AWS are collected via the DCS Argos system aboard either NOAA or MetOp polar orbiting satellites and thus made available in near real time to operational and synoptic weather forecasters. The surface observations from the AAWS network are important records for recent climate change and meteorological processes. The surface observations from the AAWS network are also used operationally, and in the planning of field work. The surface observations from the AAWS network have been used to check on satellite and remote sensing observations.

南极自动气象站（AAWS）网络于1978年首次启动，是南极最广泛的地面气象网络，其几个设施已接近30年。作为长期观测记录，它的主要重点是测量南极大气的近地表天气和气候学。AWS站点测量地面标称高度为3米的气温、气压、风速和风向。其他参数，如相对湿度和积雪量也可以测量。来自AWS的观测数据是通过NOAA或MetOp极轨卫星上的DCS Argos系统收集的，因此可以接近实时地提供给业务和天气预报员。AAWS网络的地面观测资料是近年来气候变化和气象过程的重要记录。来自AAWS网络的地面观测也用于实际操作和野外工作规划。来自AAWS网络的地面观测已被用于核对卫星和遥感观测。
