Streszczenie
\n<\/strong>Celem pracy jest okre\u015blenie w\u0142asno\u015bci optycznych i radiacyjnych aerozolu obserwowanego podczas transportu dalekiego zasi\u0119gu zanieczyszcze\u0144 wyemitowanych w Ameryce P\u00f3\u0142nocnej we wrze\u015bniu 2020 r. Badania zosta\u0142y zrealizowane w oparciu o dane pomiarowe pozyskane z fotometru s\u0142onecznego, lidaru oraz radiometru s\u0142onecznego (pyranometru) w stacji badawczej SolarAOT w Strzy\u017cowie na Podkarpaciu, a tak\u017ce w oparciu o wyniki symulacji modelem trajektorii wstecznych, modelem transferu radiacji i transportu zanieczyszcze\u0144. Wyniki bada\u0144 wskazuj\u0105 na obecno\u015b\u0107 silnie rozpraszaj\u0105cych warstw aerozolu w ca\u0142ej troposferze oraz w dolnej stratosferze (pod koniec okresu pomiarowego). Obecno\u015b\u0107 aerozolu w dolnej stratosferze jest w ostatnich latach bardzo rzadko obserwowana. Mimo tego warto\u015bci aerozolowej grubo\u015bci optycznej by\u0142y poni\u017cej \u015bredniej wieloletniej. Obecno\u015b\u0107 aerozolu w atmosferze spowodowa\u0142a redukcj\u0119 promieniowania dochodz\u0105cego do powierzchni ziemi w godzinach po\u0142udniowych o oko\u0142o 32 W\/m2. Wymuszanie radiacyjne aerozolu podczas bezchmurnych warunk\u00f3w wynosi\u0142o ok -9 W\/m2 na powierzchni ziemi i -5,2 W\/m2 na g\u00f3rnej granicy atmosfery. Oszacowane warto\u015bci efektywno\u015bci wymuszania radiacyjnego w po\u0142\u0105czeniu z pomiarami albedo pojedynczego rozpraszania wskazuj\u0105 na nap\u0142yw umiarkowanie absorbuj\u0105cego aerozolu.

Abstract
\n<\/strong>The aim of the study is to determine the optical and radiation properties of the aerosol observed during long-range transport of biomass burning pollution emitted in North America in September 2020. The research was carried out at SolarAOT research station in Strzyzow (south-eastern Poland) on the basis of measurement data obtained from a sun photometer, aerosol lidar and solar radiometer (pyranometer), as well as on the basis of simulation results with backtrajetories model, radiation transfer and aerosol transport model. The results indicate the presence of highly scattering aerosol layers throughout the troposphere and in the lower stratosphere (during the end of the measuring period). The presence of an aerosol in the lower stratosphere has been very rarely observed in recent years due low stratovolcanic activity. Despite this, the aerosol optical thickness was below the long-term average. The presence of the aerosol in the atmosphere reduced the radiation reaching the Earth’s surface at noon by about 32 W\/m2. The aerosol direct radiative forcing of the during clear conditions was about -9 W\/m2 at the Earth’s surface and -5.2 W\/m2 at the top of the atmosphere. The estimated radiative forcing efficiency in combination with the single scattering albedo measurements indicate moderately absorbing particles.
