That plot is from a commercial air quality monitor calibrated against Defra AURN monitors, so a couple of order magnitude (and some) more in price - thats omitting that it needs annual sensor renewal and calibration. It does full NO, NO2, O3, PM1, PM2.5 and PM10 readings every 10 seconds - which tbh is not frequent enough especially with NO2 sampling where the chemistry is more complex and time limiting so would benefit from oversampling and VOC monitoring if outside urban environment. Everything is then sent to severs via UTMS where it is validated and calibration coefficients applied then I apply my processing. The plot that I posted was NO2 and imaging from Google Earth. The problem with mobile monitoring is that everything is heavily correlated with what you are following and how the monitoring equipment is configured. That particular plot is largely unprocessed and would not stand up in court in its current state!
