Abstract
- This paper examines the effect of the COVID-19 induced lockdown upon six pollutants, CO, NO, NO<subscript>2</subscript>, PM<subscript>10</subscript>, PM<subscript>2.5</subscript>, and O<subscript>3</subscript>, in the Spanish community of Madrid. The paper relies on clustering methods and multiple regression techniques to control for a battery of potential confounding factors. The results show that the nationwide lockdown, decreed on 13 March by the Spanish government, exerted a statistically significant effect upon most pollution indicators. The estimates range from approximately −82% (NO and NO<subscript>2</subscript>) to −3% (CO). Reversely, the COVID-19 induced lockdown raised O<subscript>3</subscript> levels by an average of 20%. By using data from 43 stations spread out among the region, the paper provides a local level analysis. This analysis reveals substantial differences across areas and across pollutants. This observation indicates that any successful approach to improve air quality in the region must be multidimensional. [ABSTRACT FROM AUTHOR]
