Abstract

A method of investigating air temperature profiles by means of a small unscreened thermistor bead is described. Profiles measured both with this equipment and with ordinary minimum thermometers under very stable atmospheric conditions exhibited unusual features inconsistent with the generally accepted theory of nocturnal cooling of the near‐ground air layers. The minimum air temperature was found to occur at heights varying between 1.5 and 6.0 in. above the surface, and the results support the view that direct radiation loss from the air is important in determining the temperature distribution under these conditions.
