Soil Temperature, under sod (30 cm)
The average temperature during a 15-minute interval at a depth of 30 centimeters below the ground; the surface under which the measurement is taken is vegetated.
-
Thermistor probes sheathed in stainless steel are buried horizontally in undisturbed ground. Because the cables connecting the thermistors to the tower might conduct surface heat and divert draining rainwater, they were buried deeper than the thermistors, then angled upward.

This measurement was discontinued in December 2013.
