摘要
The outdoor thermal comfort of an urban area gets affected by different aspects, such as the urban materials and urban morphology (building-canopy & trees-canopy). This paper aims to investigate the effect of such different aspects on urban surface thermal performance using in-situ measurements and to predict the same by coupling a simple single-layer urban canopy model (SLUCM) with a surface energy balance model (SEBM). The asphalt road is the hottest (45 & DEG;C), with a heating rate of 5.26 & DEG;C/hour during the day. The building canopy shading creates a 2.8 & DEG;C between the air temperatures. The results indicate the importance of green areas for cooling urban spaces due to their lower warming and surface shading from tree canopy as 7.3 & DEG;C of the temperature difference between surface and air temperature reduced to 3.2 & DEG;C. Averaging all the analysis, the model evaluates the surface temperature with R-2 = 0.8824, mean bias = 1.86 & DEG;C, MAE = 2.59 & DEG;C, and RMSE = 5.13 & DEG;C.
