The study on the outdoor thermal environment around the building has been increasing in number. In such a kind of study, it is necessary to measure the factors exactly which form the outdoor thermal environment. One of the most important problem is the influence of solar radiation on the measurement of such factors in a sunny place. In this paper, it is mentioned that the influence of solar radiation on the air temperature which is measured by thermo-couple and on the globe temperature is examined by the outdoor experiments. The main contents of the outdoor experiments are as follows ; (1) The air temperature is measured by the thermo-couple, changing the diameter of thermo-couple element, the covering of its surface and shading the sunshine, to examine the relation between the measuring errors and the solar radiation and the wind speed. (2) The distributions of the temperature on the globe surface are measured, under various sun's altitude conditions, and the agreements between the average temperature of the globe surface and the globe temperature are examined. (3) The agreement between the calculated globe temperature and the measured one is examined, in connection with the duration time of the varing amount of solar radiation and the fluctuating wind speed.
