The use of satellite technology in monitoring air pollution has become increasingly important for understanding and managing environmental health. This article explores the advancements in satellite-based monitoring of air pollutants, specifically focusing on the measurements of carbon monoxide (CO), particulate matter (PM10 and PM2.5), and weather indices. Satellite remote sensing provides extensive spatial and temporal data, addressing the limitations of ground-based monitoring networks [1]. Recent studies show that geostationary satellites have great potential for continuous and wide-ranging monitoring of air quality. These satellites enable accurate estimation of surface concentrations of pollutants, allowing for real-time assessment and trend analysis [2]. The integration of satellite data with ground measurements improves the reliability of air quality monitoring systems [3]. The analysis also highlights the usefulness of satellite data in understanding the dynamics of air pollution, including the dispersion patterns and the impact of weather conditions on pollutant levels. The use of advanced satellite instruments, such as those on the Sentinel-5P satellite, has shown significant improvements in detecting and quantifying CO and particulate matter concentrations [4]. Overall, the application of satellite technology in air pollution monitoring not only provides valuable insights into pollutant levels but also supports the development of effective mitigation strategies and policies to protect public health [5].

The quality of ambient air is a noticeable demonstration because the ambient air plays a cardinal preface on the human activities and most of environmental processes. The monitoring of the quality of air is an important part of the pollution control because the ambient air was confirmed as an affected branch on the earth from both anthropogenic activities and natural phenomena. In the existing investigation, there were expected to test the selected important air quality parameters of the ambient air at around the Peradeniya region in Sri Lanka which is known as relatively populous region with the traffic. The ambient air samples were collected through a glass fiber filter paper which was attached to the high volume air sampler and both PM10 concentration and concentration total suspended particles (TSP) of the ambient air were determined using weight differences of air collection bottle and filter paper. Beside of that the lead (Pb) concentrations and NOX concentrations of the ambient air were investigated using hot acid extraction method while having the contribution of atomic absorption spectrometer (AAS) and of absorbing method in to a liquid with the aid of UV- visible spectrometer. As the results, there were obtained 0.0141 ppm of PM10 concentration, 0.0214 ppm of total suspended particles (TSP) concentration, 0.151 μg/m3 of NOX concentration and 0.015μg Pb/ m3 of lead (Pb) concentration of the ambient air at around the Peradeniya region at that moment. When comparing of those results with the air quality standards and norms, it was identified the non hazardous atmosphere at the selected region at that occasion.

The object of this investigation was the synergy effect achieved by combining lidar monitoring of particulate matter (PM) pollution in atmospheric aerosol over urban areas (city of Sofia) with in-situ sampling. The lidar systems of the Laser Radar Laboratory (LRL) of the IE-BAS were used to scan at two laser wavelengths the horizontal and vertical aerosol distributions and long-distance transport. The results demonstrated the possibility of detailed fast remote monitoring and analysis of the air pollution over entire urban regions, providing fast estimates of the air pollution transport over the city, as well as detection of sources of extreme emissions. Once the place of high PM concentration was localized by the lidar, samples were taken using a Hygitest 106 (Maimex) – a high-efficiency portable device for sampling and concentration determination of PM in atmospheric aerosol. The data presented pertains to the winter period 2018 year. PM pollutions than 10 and 2.5 μm were under studied. The lidar maps created can be further used for tracing the full air mass transport carrying contaminations from various pollution sources (chemical, biological, dust, etc), distributed over the scanned region. Further, the sampling schedule was conformed with the seasons of the year, in order to reveal any characteristic seasonal hazardous microbial contamination.
