The ARM Surface Meteorology Systems (MET) use mainly conventional in situ sensors to obtain 1-minute statistics of surface wind speed, wind direction, air temperature, relative humidity, barometric pressure, and rain-rate.

Sensors may be added to or removed from the base set depending upon the deployment location, climate regime, or programmatic needs. Sensor types may also change depending upon the climate regime of the deployment.
