Summary: This report is a discussion of various thermal errors associated with the measurement of ground and air temperatures. Errors associated with the digging of a pit and plunging temperature measuring devices into the ground through the side walls are considered. The effect of electric currents in resistance thermometers and in thermistors and the effect of radiation penetration in the ground are discussed. The types of errors associated with a long vertically installed temperature sensing unit are mentioned. Steady-state and transient errors associated with air temperature measurement under various conditions are presented.
