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.

应用卫星数据和 GIS 服务研究立陶宛的空气污染物（案例研究：考纳斯市）

卫星遥感的历史相对较短，将在涉及地点和空间主题的领域中发挥重要作用。通过这项技术创新，对地球表面不断变化的现象进行实时监测和测绘成为可能。本研究的目的是使用环境站数据和卫星数据（Terra、Aqua、OMI 和 Sentinel-5P）调查和评估 2019 年 10 月 14 日至 25 日期间考纳斯市的空气污染物。使用从卫星获得的数据和从位于考纳斯不同地区的空气质量监测站收集的污染物数据。下载了上述天数的数据，用于考纳斯市的地理范围。每个数据文件覆盖了立陶宛大小的区域；因此，我们应该提取感兴趣区域的数据，即考纳斯市。这项研究的总体结果证实了 Sentinel-5P 数据可用于监测考纳斯当地的空气质量和空气污染。卫星数据与原位测量之间存在强且可接受的相关性表明卫星图像有能力监测空气污染，特别是在 Alytus 市火灾事件期间考纳斯市区的空气污染。
