I’ve set up the plume plotter and it seems to be running OK. Please check, especially:
I’ve also done some annual mean plots of NO2 fallout, using Newcastle airport weather for 2015 and 2016. These should be compared with their Figure 5.8 (for an unknown year’s weather). My plots (attached) show slightly lower pollution than theirs (1.39 and 1.11 instead of 2.13), but this might be because they chose a bad year (earlier than 2015). Or it might be that they included emissions from the diesel generator and increased traffic? It’s hard to be sure because the air quality assessment is very badly written. E.g. there is no description of Figure 5.8.
