“…It can help to identify hot spots and to quantify BC levels on roads and 100 highways as well as in various other mobile environments (Apte et al, 2011, Dons et al, 2012, Madueño et al, 2019 including bicycles (Wójcik et al, 2014, Samad andVogt, 2020), trains (Andersen et al, 2019), and airplanes (Kim et al, 2019). The device can also be applied in long-term stationary monitoring, vertical profiling, and atmospheric measurement with unmanned aerial vehicles (Cao et al, 2020, Chiliński et al, 2018, Pikridas et al, 2019, balloons (Ferrero et al, 2016, 105 Markowicz et al, 2017, Samad and Vogt, 2020, community monitoring, indoor air quality monitoring, and the assessment of personal exposure and related health effects (Isley et al, 2017). In order to reduce the noise of data obtained with high time resolution, the data measured by the instrument can be smoothed.…”
