TAIR
Air Temperature (1.5 m)
The 5-minute average air temperature at a height of 1.5 meters above the ground.

This sensor is quite rugged and accurate. Prior to 2009, the sensor was housed in a naturally-ventilated radiation shield. Such shields can create temperature errors of several degrees Celsius when the wind is calm (less than 1 m/sec) and solar radiation is high.
-
Since 2009, the sensor is housed in an aspirated radiation shield, which continuously draws ambient air over the sensor, while protecting it from solar radiation.
