This tool is part of a suite of tools developed for Local Air Quality assessments. It estimates the annual mean nitrogen dioxide concentrations at one distance from a road, using measurements made at a different distance from the road. It is particularly useful where compliance with the annual mean objective cannot be directly ascertained from the monitoring data.
This tool can be used to justify the process i.e. help assess air quality concentrations.
