In this work, two air quality simulations are run to analyze the impacts of the reduction of anthropogenic emissions during COVID-19 lockdown over Madrid (Spain) area: one simulation considers the emission reductions during the lockdown (COVID simulation) and a second simulation, "business as usual" (BAU simulation) with an emissions' scenario without restrictions. Source apportionment techniques are used to identify and quantify the contributions from main pollution sources with the purpose to provide understanding on what measures should be taken to address them, and this work shows the potential of this technique. This study helps to elucidate the complex and nonlinear response of O3 and PM concentrations after a reduction of emissions, mainly from the transport sector, during the COVID-19 lockdown period.
