Kalisz's air quality reflects the flat Kalisz-Ostrów Basin in central western Poland, with vehicle traffic on the A2 motorway and the surrounding textile and manufacturing industry in one of Poland's oldest cities contributing local sources. Winter residential coal and wood burning generates seasonal PM2.5 elevation, while the flat Great Polish lowland provides reasonable dispersal on most wind days and consistent westerly airflows provide background ventilation.
