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.
This sounds very interesting. Do you have more info? If you’re comfortable sharing since I guess you’d be doxxing your hometown lol

I just meant that holiday they referred to, where everyone leaves the main city or whatever
I’d be curious to know which places are not like that. Aren’t most cities emptying up for holidays?
