Driving or walking around to measure an area or even a whole city works beautifully as we discovered previously. While that gives us the right amount of control over what and how much we measure an area, it can also be costly. For that reason we explored measuring air quality of a whole city using a food delivery service.
One of our “Care for Air” ambassadors works for a food delivery service, and he was kind enough to have our equipment mounted on the rooftop of his car for a week. As can be seen below measuring this way works out quite well. To create more coverage, it will be needed to deploy on several food delivery units.
This test was more about testing the coverage using this deployment model than about interpreting the actual data. So when trying to understand these views, note that the colour coding should officially be based on an hourly average, which is not necessarily the case here. This means that estimation of harm by these coloured categories might be over-estimated.
As for the actual pollution measured, the higher values in these views are due to ozone (O3), which is produced by air chemistry in combination with other pollutants when the sun is shining. Other pollutants were mostly nitrogen dioxide (NO2), which is produced by motorised vehicles. Dust-levels on that day were very low.
