    No idea where they live but here in Brussels there is public data available so it’s relatively easy to keep track of different kind of particles in the air. I imagine there is a proxy for how busy a city is on a specific day that would help make a correlation with some assumptions. https://ec.europa.eu/eurostat/ must have something on both.

        I’d be curious to know which places are not like that. Aren’t most cities emptying up for holidays?
