Gdy jedna strona m\u00f3wi: Mamy popraw\u0119 jako\u015bci powietrza, a druga odpowiada: Tak, ale to tylko dlatego, \u017ce zima by\u0142a \u0142agodna i ludzie nie palili tak w piecach<\/em><\/strong>, pojawia si\u0119 pytanie: kto ma racj\u0119? <\/em><\/p>\n\n\n\n

Aby odpowiedzie\u0107 na to pytanie autorzy niniejszego opracowania postanowili przyjrze\u0107 si\u0119 wp\u0142ywowi czynnik\u00f3w meteorologicznych na zmiany w jako\u015bci powietrza obserwowane w ostatnich latach. Przy u\u017cyciu zaawansowanego modelu statystycznego (random forest model<\/a>) okre\u015blono jaki jest udzia\u0142 warunk\u00f3w pogodowych, a jaki dzia\u0142a\u0144 cz\u0142owieka w poprawie jako\u015bci powietrza. Do analiz wykorzystano godzinowe st\u0119\u017cenia py\u0142u PM10 z bazy GIO\u015a oraz dane meteorologiczne z bazy IMGW. Wybrano lokalizacje, kt\u00f3re posiada\u0142y najd\u0142u\u017csz\u0105, kompletn\u0105 seri\u0119 pomiarow\u0105 od roku 2008 do 2019 zar\u00f3wno w zakresie st\u0119\u017ce\u0144 PM10, jak i parametr\u00f3w pogodowych. Wyniki prezentuj\u0105ce redukcj\u0119 st\u0119\u017ce\u0144 py\u0142u PM10 pomi\u0119dzy latami 2010 a 2019 przedstawiono w Tabeli (poni\u017cej), w podziale na: uwzgl\u0119dniaj\u0105ce jedynie dzia\u0142ania ludzi, po wyeliminowaniu wp\u0142ywu czynnik\u00f3w meteorologicznych (kolumna c); rzeczywiste pomiary, uwzgl\u0119dniaj\u0105ce zar\u00f3wno czynniki pogodowe, jak i dzia\u0142ania ludzi (kolumna d). <\/p>\n\n\n\n

Najwi\u0119ksz\u0105 redukcj\u0119 dzi\u0119ki dzia\u0142aniom ograniczaj\u0105cym wielko\u015b\u0107 emisji (po wyeliminowaniu wp\u0142ywu czynnik\u00f3w meteorologicznych) uzyskano dla dw\u00f3ch stacji w Krakowie<\/strong>: 22,9 \u00b5g\/m3 i 22,6 \u00b5g\/m3. Z kolei najgorsze wyniki uzyskano dla dw\u00f3ch stacji w Gda\u0144sku i jednej w Warszawie, gdzie aktywno\u015b\u0107 ludzi przyczyni\u0142a si\u0119 do zwi\u0119kszenia st\u0119\u017ce\u0144.<\/p>\n\n\n\n
