Observational Study for the Thermal Environment Evaluation of Summertime over the Asphalt Pavement - Case Study in Daegu 2014 - Kim, Hae-Dong; Kim, Sung-Rak; Kim, Baek-Jo;
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 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 are as follows: An hour that had the daily maximum temperature was around 15 pm and the value was approximately. Net shortwave radiation was the highest at 12pm as and much radiation of was absorbed at the ground between 11am and 17pm. Sensible heat that was delivered from the ground to the atmosphere was evaluated as between 10am and 19pm. underground transfer heat up to was measured as negative from 19pm to the next day 8am, which indicated the lower atmosphere was heated at night.
