Inclusion of land cover and traffic data in NO2 mapping methodology ETC/ACM Technical Paper 2016/12

Next to this, mapping of traffic related air quality using measurement data from traffic stations and available supplementary data has been explored. Different options on how to include best such a traffic map layer in the background map and in the exposure estimates has been examined. All analyses have been based on 2013 data.

As a result one concludes that inclusion of land cover and road data brings clear improvement of NO2 mapping methodology. Recommended is to implement these supplementary data sources in the routine methodology, and simultaneously move the application of the 1x1 km resolution from the combined final merging process-step to the early process-step of creation of the separate rural and urban background map layers. It is recommended to include the traffic map layer into the routine NO2 maps and exposure estimates.
