Abstract

A little more than sixty years ago, the late L. A. Ramdas discovered a curious atmospheric phenomenon which had not been satisfactorily explained till recently. The phenomenon is the observation of a temperature minimum some 20-50 cm above bare soil on calm, clear nights. The first reports of these observations were treated with much scepticism, as the prevailing view was that the nocturnal temperature minimum always occurs at ground. In the present address the history of work on the lifted temperature minimum is traced and a new explanation is offered. It is emphasized that in this as well as many other phenomena, it is important to account for surfaces that are not perfectly black radiatively, i.e. those whose emissivity is not unity.
