IMPACT OF COVID-19 LOCKDOWN ON NO2, NOX, O3 AND PM2,5 CONCENTRATIONS IN SANTIAGO DE CHILE

ABSTRACT Based on the spread of the COVID-2019, a lockdown was declared in the Santiago Metropolitan area in Chile. The application of containment measures allowed to reduce the impact of the COVID-2019 pandemic on the National Health System (MINSAL) but at the same time these restriction measures g...
