The main objective of the COST Action 732 is the improvement and quality assurance of micro-scale obstacle-accommodating meteorological models and their application to the prediction of flow and transport processes in urban or industrial environments. This report contains the full best practice guidelines for undertaking simulations that are used to evaluate microscale obstacle-accommodating meteorological models Summaries of this report have been published as the following documents : Franke, J., Hellsten, A., Schlunzen, H.
