The straight-line relationship between temperatures at a given depth and the surface temperatures combined with 5-day average air temperatures appears to be as valid for upper New York State and Arizona as it was for Maryland. The main differences were in the ranges and mean temperatures. Values given herein are for straight-line equations for all 24 hours and for the depths of 2, 4, 6, 8, 10, and 12 inches (5.1, 10.2, 15.2, 20.3, 25.4, and 30.5 cm). The original concept appears to be valid and may be used with confidence for estimating pavement temperatures at other latitudes and longitudes.
