Abstract Satellite remote sensing, with its relatively short history, is going to play a major role in the fields that encompass topics related to place and space. Through this innovation in technology, real-time monitoring and mapping of changing phenomena on the surface of the earth has been possible. The purpose of this study was to investigate and evaluate the Kaunas city air pollutants between 14 and 25 October 2019 using environmental station data and satellite data (Terra, Aqua, OMI, and Sentinel-5P). The data obtained from satellite and the pollutant data gathered from air quality monitoring stations located in different parts of Kaunas were used. The data was downloaded for days mentioned above for the geographical bound of Kaunas city. Each data file covered an area of the size of Lithuania; hence, we should have extracted data for the area of interest, which was Kaunas city. The overall results of this study confirmed the capability of Sentinel-5P data to be used in monitoring the air quality and air pollution over the Kaunas local area. The existence of strong and acceptable correlations between satellite data and in situ measurements was indicative of the ability of satellite images to monitor air pollution, particularly over Kaunas urban areas during the fire incident in the city of Alytus.

Introduction Several studies conducted around the world have confirmed the adverse effects of air pollution on human health (Brunekreef and Holgate 2002; Hoek et al. 2013; Liu et al. 2013; Clark et al. 2014; Evans et al. 2014; Brook et al. 2017; Usmani et al. 2020). Monitoring environmental pollutants over urban areas using remote sensing methods is recommended to achieve sustainable development (Putrenko and Pashynska 2017). During the past 20 years, information about SO2 and NO2 vertical column density (VCD) and aerosol optical depth (AOD) has been collected by several satellites globally; such data are used to restrict estimation of emissions at different spatial resolutions (Wang et al. 2020). * Arezoo Soleimany [email protected]; [email protected] 1

Controlling the air quality of cities through regulations would be an effective way provided that main areas are thoroughly monitored; thus, it is possible to quantify emissive pollutants and understand their chemical processes in the atmosphere.
