Poland, March 2024
For 2 days, from 20 to 21 March 2024, 40 cities in Poland had PM2.5 at least twice their usual for the time of year. The worst reading was Łask, Łódź Voivodeship, Poland: 65.9 µg/m³ on 20 March, about 2.1× its usual 30.7.
No cause named We have no fire or smoke records for these days, so we only say what the measurements show.

An episode is a run of days when many cities close to each other (four or more within 350 km on a day, 8 or more in all) each had a daily PM2.5 mean of at least 25 µg/m³ and at least 2 times their usual for that time of year. Found in our own measurements, not picked by hand. How we find episodes . Values are each city's daily mean of its own monitors; causes are the usual kinds for a pattern like this, not a confirmed source.
