Abstract
One type of Sanborn rod thermistor is studied with respect to the accuracy of measurement of air temperature. Compensation techniques are reviewed and inaccuracies, uncertainties, and lag coefficients are evaluated. Shielding of thermistors from solar and long-wave radiation is examined. With yearly calibration and proper shielding, temperatures may be measured with an accuracy of at least 0.4C°.
