If I may use your expertise a bit: I need air quality data for two cities, one of which doesn't have any air quality monitoring stations. Is there anything I can use as a proxy for air pollution, like satellite data? Also, do you know any sources for that data?

Thanks!

P.S.: I'm passionate about air quality, given I have alergies and was an active member of the bicycle activism movement for about 10 years.
