摘要: Highly time-resolved particle number size distributions (PNSDs) were evaluated during 5 years (2013–2017) at four background stations in the Czech Republic located different types of environments—urban (Usti nad Labem), industrial (Lom), agricultural (National Atmospheric Observatory Kosetice), and suburban (Prague-Suchdol). The PNSD data was used for new formation event determination as well growth rate (GR) condensation sink (CS) calculations. differences or similarities these parameters from perspectives pollution load, meteorological condition, regional long-range transport. median (4 nm h−1) is very similar all stations, most frequent length lasted between 2 4 h. Condensation reflects load individual station their connection to environment type. highest median, CS = 1.34 × 10−2 s−1, recorded urban lowest (CS 0.85 s−1) Kosetice). Conditional probability function polar plots illustrate influence source location GR. These primary potential emission sources involve traffic, operation a power plant, domestic heating.
