Two shadow models are compared focusing on the energy fluxes. The first one uses a simplified geometry of the building, this approach is included in the Urban Canopy Model (UCM). The second one is a new three-dimensional urban solar radiation model (SHAMO) which has been developed by the authors of the present contribution. It has been developed to calculate short wave radiation over urban high resolution grids.
The data produced by the urban solar radiation model has been used in large scale numerical experiments to simulate turbulent fluxes for urban areas; in this contribution over Madrid (Spain) city. We have applied a modified version of the EULAG (UCAR) micro scale model (CFD) which includes an energy balance equation to obtain the urban atmosphere/biosphere energy exchange. Results of the micro scale simulations and sensitivity analysis related to the solar radiation approach will be presented in this paper.
