Abstract
This paper reports on the evaluation of Simple Urban Energy Balance for Mesoscale Simulation (SUMM) to two cities (i. e. Kugahara, Japan; Basel, Switzerland) in winter, spring and summer. This new version of SUMM is incorporated with vegetation scheme to meet the existence of vegetation fraction in real city. SUMM simulated the urban energy balance and radiative temperature (Tr) generally well in Kugahara and Basel. However, SUMM slightly underestimated Tr in the nighttime and overestimated Tr in the daytime in Basel.
