自动气象站（AWS，Automatic Weather Station）是一种自动化的气象站，可节省人力并可测量偏远地区的气象数据。该系统通过Argos系统和全球电信系统以进行实时回报，或保存数据作日后发送。

云的种类、云量以及雾等接触不到传感器、需肉眼观察的天气现象，仍然要人工监测。此外，降水测量是对雪显得有点问题，因为量器必需在每次测量时清空，对于目前的技术所限，只能在几乎不会降雪的地方使用。

自动气象站往往被放置在供电网络和通信网络内。现在，太阳能电池板、风力涡轮机和流动电话技术使自动气象站能在供电网络和通信网络外的地方，透过无线型式发送数据。

An automatic weather station (AWS) is an automated version of the traditional weather station, either to save human labour or to enable measurements from remote areas. An AWS will typically consist of a weather-proof enclosure containing the data logger, rechargeable battery, telemetry (optional) and the meteorological sensors with an attached solar panel or wind turbine and mounted upon a mast. The specific configuration may vary due to the purpose of the system. The system may report in near real time via the Argos System and the Global Telecommunications System, or save the data for later recovery. In the past, automatic weather stations were often placed where electricity and communication lines were available. Nowadays, the solar panel, wind turbine and mobile phone technology have made it possible to have wireless stations that are not connected to the electrical grid or hardline telecommunications network.
