Improvements in air quality in the Netherlands during the corona lockdown based on observations and model simulations.

ABSTRACT: The lockdown measures in response to the SARS-CoV-2 virus outbreak in 2020 have resulted in reductions in emissions of air pollutants and corresponding ambient concentrations. In the Netherlands, the most stringent lockdown measures were in effect from March to May 2020. These measures coincided with a period of unusual meteorological conditions with wind from the north-east and clear-sky conditions, which complicates the quantification of the effect of the lockdown measures on the air quality. Here we quantify the lockdown effects on the concentrations of nitrogen oxides (NO_x and NO₂), particulate matter (PM₁₀ and PM_2.5) and ozone (O₃) in the Netherlands, by analyzing observations and simulations with the atmospheric chemistry-transpo
