OBSERVATION OF SOLAR AND LONG-WAVE RADIATION FIELDS IN URBAN CANYON BY USING A CUBIC RADIOMETER

Observation of solar and long-wave radiation fields was carried out using a cubic radiometer at the eight points in the urban area including canyon in a clear day on March. The measurement was practiced three times of morning, afternoon and evening with 10 minutes recording at each point. The radiation fields from the viewpoint of energy transfer are analyzed for radiation fluxes incident on the horizontal plane. From the viewpoint of bioclimate, the radiation fields are evaluated with the equivalent air temperature, the operative temperature and the SET*. Key words: net radiation flux, equivalent air temperature, cubic radiomete
