Abstract: The aim of this paper is to describe the use of a general methodology tailored to the evaluation of micro-scale meteorological models applied to flow and dispersion simulations in urban areas. This methodology, developed within COST 732, has been tested through a large modelling exercise involving many groups across Europe. The major test case used is the Mock Urban Setting Test (MUST) experiment representing an idealised urban area. It is emphasised that a full model evaluation is problem-dependent and requires several activities including a statistical validation that requires a careful choice of the metrics for the comparison with measurements.

Keywords: COST Action 732; CFD models; non-CFD models; model evaluation; MUST; idealised urban areas; computational fluid dynamics; micro-scale models; meteorological modelling; flow patterns; dispersion modelling; mock urban setting test.
