| Zusammenfassung |
| On this poster we present NO2 measurements using a Cavity-Enhanced DOAS on a
measurement bus which we used to chase other vehicles to measure their NO2
emissions. Emissions of nitrogen oxides from on-road vehicles have received highly
attention recently due to the increasing trend of ambient NOx level. It is particularly
important to identify and quantify the direct emission and secondary formation of
NO2 contributed by traffic emissions, in order to study the impact to the local air
quality.
We sampled on-road emissions in different environments and different driving
conditions (e.g. urban, highway, different speeds). We analyse the data set in terms of
spatial and temporal variability to search for temporal and spatial patterns. We
present mean values sorted for different vehicle types, distance to the target car and
travelling speeds to provide an emission data base from this measurement study. |
