Few years ago Kraków has forbidden the use of solid fuels which improved the situation significantly. Days like today are happening much less often since then. Moreover, Kraków has probably one of the densest network of pollution sensors in the world, which is why we talk about it at all. There are places in Poland that are much worse off, but there's not that much data to back it up.

My understanding is that the problem is exacerbated by the shape of surrounding terrain and atmospheric conditions. I.e. the city is in a cavity and on cold days there is a mass of high pressure that pushes all the smog down.

But you are correct I believe (hailing from Wro here) - there have been many countermeasures implemented and cities are packed with sensors. Only so much can be done.

also the neighbouring municipalities are still burning solid fuels, and the city can't do anything about that.

I might be wrong, but I thought the situation in Kraków improved significantly several years ago due to the efforts of local administration, so much that we were jealous here in Warsaw. Has it worsened again since then?

> improved the situation significantly

That's just yet another coping mechanism, I believe.

I lived in Krakow in ~2015, and live there now. It's the same. It smells the same, it looks the same, the polution levels are the same, and the number of days like today in a year is the same.

That's not what the data [1] says.
