Well the Oklahoma Mesonet is setup where the air temp gauge is 1.5 meters above the ground or about 5 ft. I would think it would be the same for NOAA and NWS.

Meteorological instruments for measuring temperature, pressure, humidity etc are housed in a white, slatted box called a Stevenson Screen (devised by the father of Robert Louis Stevenson, I think his first name was Thomas).
Different organisations use different criteria so the height above ground varies. The lowest that I'm aware of requires the base of the screen to be 1.0m (3ft 3in) above ground level, the highest is 1.5m (4ft 11in). The requirement for the official weather service is 1.25m (4ft 1in). I can't remember which organisation but in the past 3ft 6in was one of the required heights.

I like Trevor's answer a lot. Well organized facts.
When we set one up in the yard outside the Physics building in 1968, the instructions from the manufacturer said 4 feet 8 inches, which is well within the range Trevor mentions.
