DescriptionSummer temperatures under trees planted in holes cut through an asphalt cover in a parking lot and in soil beneath the surrounding asphalt were higher than soil temperatures under trees at a control site. Winter minimums were not different, but maximum summer temperature exceeded the control by 3ºC beneath the parking lot trees and up to 10ºC beneath the asphalt cover at a depth of 15 cm below the surface. Horizontal and vertical soil temperatures varied little at a given time within each type of site. Asphalt covering the soil not only increased maximum temperatures through a 60-cm profile, but apparently increased the rate of heat exchange since temperatures in the covered soil rose and fell more rapidly than control soil temperatures. The soil, even when covered, could be a sink or source of excess heat exchange in the urban energy balance.
