Urban Air Quality and Tropospheric Ozone Under Changing Emission Patterns in Southern Brazil: Insights From the Covid-19 Restriction Period
In this study, we evaluated the influence of COVID-19 social restrictions on tropospheric ozone (O₃) concentrations in Pelotas, a mid-sized city in southern Brazil, aiming to understand how anthropogenic emission reductions and seasonal climate patterns modulate urban air quality in the South American context. Using a...
