A subgrid model was developed in order to improve the surface energy budget evaluation over large urban areas. The model is capable to evaluate the energy budget of each building belonging to a built up area by employing an accurate canyon geometrical description. It was coupled with the limited area model RAMS and was applied to simulate the urban heat island over the metropolitan area of Rome.

Abstract
A subgrid model was developed in order to improve the surface energy budget evaluation over large urban areas. The model is capable to evaluate the energy budget of each building belonging to a built up area by employing an accurate canyon geometrical description. It was coupled with the limited area model RAMS and was applied to simulate the urban heat island over the metropolitan area of Rome. The model was initialized with an urban digital elevation model, accounting for nearly 360,000 buildings. The results shows that the subgrid model is able to reproduce the behaviour of the main meteorological quantities.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
