You do realize that it can be extra disgusting?

No, it's a visual bias.

how is it a visual bias?

normally when i walk my dog and wipe their feet, black stuff comes off. after it rains and i wipe my dog's feet, it's pretty clean.

similarly with snow, my shoes and pants get splattered in spots from the dirty snow's dried mud.

Because there is no sudden variable that makes the city coincidentally dirtier on a (random) snow day than any other day of the year. You're only seeing the dirt accumulate suddenly and visually in the snow. A visual bias.

You would need to show data that there is an external variable at play on that specific day. E.G. Rise of traffic. Factories pumping out more soot. Then you would have to show why it coincidentally only happened on snow days and why. Also, what happens if it doesn't snow on these days that you showed the variables to be planned to release more dirt and pollution. A near impossible task.

doesn't dirt accumulating in the snow make it extra dirty? just like when it rains, the dirt is washed away so it's cleaner
