WRF-Chem output- concentrations for the two simulations: Business as Usual and COVID for the two periods, March-April and May

The WRF-Chem model was utilized to calculate the changes in O3 chemistry during the COVID lockdown period. We ran two simulations: (1) Business As Usual (BAU) and (2)  COVID for the lockdown (30 March to 12 April 2020) and relaxation (18- 25 to 30 May 2020) periods. 

Here, we provide modelled concentrations for several chemical and physical species for 30 March to 12 April (only weekdays) and 18 to 30 May (only weekdays) for both simulations, BAU and COVID, over the AMB area during the morning (6-8 UTC), afternoon (13-15 UTC) and evening (19-21 UTC) hours. 

We also provide the WRF-Chem output used to create the air parcel trajectories and the ozone concentrations from the Metropolitan Area of Barcelona to the Pyrenees.
