| Research Abstract |
This study revealed that the temperature of the whole boundary layer falls first, after that, cooling stops and the boundary layer upper part makes stratification gradually after recording the maximum temperature in the afternoon to the sunset at kyoto city. This shows that the atmosphere itself is cooled by radiation. It seems that it is because the wavelength range which is strongly effective to the balance of all the air layers as this cause differs from the wavelength range of the infrared rays which are effective against the balance of a boundary layer.
