Description
Summary:	Previous experimental studies have dealt with the earth's surface and subsurface temperature profiles. The results from these studies have been summarized and analysed jointly, making it possible to derive some generalizations. It appears that the temperature range decrement factors for the different studies fit within a narrow range, and that they suggest a classification by climatic type. The values for the time lag in the annual temperature wave were also found to fall within a narrow range. Simplified equations are presented for determining soil temperatures and time lags as a function of depth. Different approaches for estimating the surface temperature are presented and discussed.
