Air pollution is a severe threat to public health and has been proven as the main cause of many fatal diseases. Across Europe, air quality in Poland is one of the worst. Thus, there is a strong demand for air quality monitoring in Poland in order to raise public awareness and to develop policies that will mitigate this huge problem. The Chief Inspectorate for Environmental Protection (GIOS) performs in-situ measurement of pollutants in a few selected, densely populated locations in Poland. In smaller cities, there is no information on the level of air pollution. This study have contributed to support the air quality monitoring in Poland by means of satellite data.

The main objective of the research was to verify potential of the Sentinel-5 Precursor (Sentinel-5P, S-5P) satellite Tropospheric NO2 Column Number Density product (NO2 TVCD) generated by the European Space Agency (ESA), to support air pollution monitoring in Poland. In this respect, the product was compared to in-situ measurements provided by the GIOS. The secondary objective of the project was to establish a relationship between air pollution (based on Sentinel-5P products) and meteorological data provided by European Centre for Medium-Range Weather Forecasts (ECMWF) by ERA5 reanalysis model.
