Modelling performance As described above, the first step in our modelling proce- dure involved the assessment of annual average PM 10 and NO 2 concentrations, using a combination ... Our dispersion modelling approach, resulting in hourly average concentrations, is a refinement of this former modelling procedure. An addi- tional validation study of this refined modelling pro...
