Geospatial applicability optics of the TROPOspheric monitoring instrument (TROPOMI) on a global scale: An overview

• Applications resulting from the use of Sentinel-5P satellite images on a global scale. • TROPOMI sensor detections consolidate new public policies to mitigate air pollution. • Studies show high concentrations of air pollutants on a global scale. Studies arising from literature reviews are important as they facilitate specific understanding about the use of the Sentinel-5P satellite developed by the European Space Agency (ESA) to detect the concentration levels of atmospheric pollutants on a global scale. The objective of this literature review is to analyze the application of the geospatial optics of the Sentinel-5P satellite; coupled with the Tropospheric Monitoring Instrument (TROPOMI) in the detection of NO 2 and CO over the period beginning in May 2018 and lasting through May 2024. This was accomplished using manuscripts published in the ScienceDirect databases. The study employed the rigorous Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) method, using the specific search term ‘sentinel TROPOMI satellite’, which yielded 555 results published between 2018 and 2024. Subsequently, 274 manuscripts were selected, and 85 were classified for analysis after a concise review. The Content Analysis Method (CAM) was used to understand the absolute frequency, with the use of the MAXQDA software (version 24.2.0) in this analysis. The purpose of using TROPOMI in the 85 manuscripts analyzed is significant. The manuscripts studied focused on air quality monitoring (30.1%), COVID-19 impact detection (24.3%), assessment of pollution sources (23.3%), support for decision makers (13.6%) and the development of methods and tools (8.7%). In this context, 38.5% of the examined studies focused on Asia, followed Europe (29.2%), North and South America (25.1%) and Africa (7.3%). TROPOMI data makes it possible to contribute to creating future government public policies on both the local and global scale.
