To investigate the thermal environment over the summertime asphalt pavements, an automatic weather observation system
was installed at a parking lot paved with asphalt to observe various meteorological parameters and surface temperature from
July 1 to September 30, 2014. Since the number of rainy days in summer of 2014 particularly after the mid July is more than
that of average data, a ratio of daily peak surface temperature above 45 ℃ was 28% which was lower than the average. The
observational data about hourly average surface temperature and various heat balance factors at days where daily peak surface
temperature is above 45 ℃ are as follows: An hour that had the daily maximum temperature was around 15 pm and the value
was 49℃ approximately. Net shortwave radiation was the highest at 12pm as 800 W/m2 and much radiation of 500 W/m2 was
absorbed at the ground between 11am and 17pm. Sensible heat that was delivered from the ground to the atmosphere was
evaluated as 200 W/m2 between 10am and 19pm. underground transfer heat up to 100 W/m2 was measured as negative from
19pm to the next day 8am, which indicated the lower atmosphere was heated at night.
