Comparison Between Remotely-Sensed and Numerically-Simulated High-Resolution Surface Temperatures at an Urban Commercial Site

This study compares high-resolution urban surface temperatures (Ts) obtained through airborne-remote sensing and from a heat balance simulation model to clarify the characteristics of detailed Ts distributions within an district confirmed capabilities limitations for assessment. The remote observations were conducted in daytime summer winter. For simulation, three-dimensional (3D) geometry component material data collected by using previously developed modeling method, materials database, field surveys. 3D simulated winter days. Both numerical showed effects solar reflectance, also time-integrating capacity materials. point-to-point comparison results between numerically remotely sensed Tr revealed that was close at many points both seasons. values slightly smaller than those these owing emissivity. It is can effectively simulate distribution with airborne data. factors causing difference assessed as mixels image, reproductivity model, actual microclimate anthropogenic emission, limitation used one-dimensional (1D) conduction equation.
