This technical guidance provides an in-depth methodology to undertake model verification for detailed dispersion modelling of road traffic emissions. Model verification is undertaken to validate dispersion modelling results (modelled concentrations) against monitored concentrations.
This guidance supports detailed assessments undertaken under the NZTA Guide to assessing air quality impacts from state highway projects.
