Description of the Different Model Simulations Used in the Present Study

Case	Name	Reduction in emissions	Meteorology	Notes
1	Control (2020)	None	MERRA‐2 for 2020	Control with business‐as‐usual 2020 emissions (no COVID effect)
2	Climato (2015–2019)	None	MERRA‐2 evolving from 2001 to 2019	Repeated emissions
3	COVID‐All (2020)	All emitted species	MERRA‐2 for 2020	Combined emission adjustment for COVID effects
4	COVID‐NOx (2020)	NOx only	MERRA‐2 for 2020	Impact of NOx only adjustment
5	COVID‐VOC (2020)	VOCs and CO only	MERRA‐2 for 2020	Impact of VOC and CO reduction only adjustment
