Air pollution is one of the most significant environmental challenges affecting ecosystems, plants and human health, making it a key area for finding solutions to conserve the natural elements involved. Understanding the temporal dynamics of atmospheric pollutants and their relationship with anthropogenic activities is essential for developing effective conservation strategies. COVID-19 pandemic offered a unique opportunity to study how changes in anthropogenic activities influence air pollutant concentration at regional and urban scales. This study analyzes the temporal variation of nitrogen dioxide (NO₂), carbon monoxide (CO) and sulfur dioxide (SO₂) in Hungary, using data from the Sentinel-5P TROPOMI. The analysis covers pre-pandemic, pandemic and post-pandemic periods, for identifying changes in pollutant behavior and seasonal dynamics. The results indicate that all three pollutants exhibit clear seasonal patterns, characterized by higher concentrations during colder months and lower levels during warmer periods. NO₂ showed the most pronounced decrease during 2020 and a rebound effect in 2021, with concentrations increasing and, in some cases, surpassing pre-pandemic levels. CO exhibited a more complex response. Although an apparent decrease during the pandemic period was observed at a country scale; relatively higher concentrations were observed on the city scale. SO₂ showed the highest variability and the weakest response to lockdown measures. Despite a slight reduction was observed, its behavior was characterized by fluctuations and peaks, specifically in early 2021. Overall, the results demonstrate that air quality responses to COVID-19 restrictions are pollutant specific and largely determined by emission sources. While NO₂ is strongly linked to traffic and mobility, CO and SO₂ reflect more complex dynamics associated with stationary sources
