Radiation environment over the watered pavement and the highly reflective pavement, which have been developed for mitigation of the heat island phenomenon, were compared with that over a paved asphalt and natural turf under the same meteorological condition. Possible absorptions of long- and shortwave radiation by a supposed globe placed at 50cm above these surfaces were calculated. It is found that the highly reflective pavement had a potential to degrade the thermal environment over it due to the increase of reflected solar radiation, while the watered pavement did not have such a side effect. Human thermal environment can be improved more effectively by shading and/or selection of the color of clothes than by changing the types of pavements. The estimated SET^* on the watered pavement showed its superiority over that on the highly reflective pavement from the standpoint of the thermal comfortability at lower leg level.

The field observation shows that the leaf surface of the vegetation top iscooled to the lowest temperature in the vegetation by the sky radiation, while the air temperature inside the vegetation stays warmer during the clear night. The leaf surface of the vegetation top is refrigerated by the sky radiation, then the air next to the vegetation top is got cooled by the sensible heat exchange from the air to the leaf surfaces. Because of the observation errors on the leaf surface temperature, the calculated results have not completely agreed with the field experiments. The calculation results shows that the atmospheric air is easily got cooled if the leaf area index is large in the tall tree crowns.
