抄録

Thermal IR images obtained with an IR radiation thermometer installed on the roof of a high building and topographic factors evaluated from the data set of altitude (Digital National Land Information, Japan) are used together in the present method of analyzing local climates, especially during a calm night. The radiative temperature of a particular evergreen canopy, which is read from the thermal IR image and will be called the “canopy temperature”, is shown to be in good agreement with the air temperature around tree crowns making up the canopy if the effect of water vapor in the atmosphere is removed. The canopy temperature is deeply influenced by the surrounding terrain features as well, and its regression equation on the topographic factors is constructed with high significance. Consequently, using the regression equation, air temperature distribution in complex terrain, especially at hight, can be estimated, which is served for a study of thermal belts on hillsides.
