Abstract

In order to limit the propagation of COVID-19 among the Moroccan population, all industrial activities were suspended since March 20th 2020. The present study investigates the possible change in atmospheric pollutants (ozone O3, particulate matter PM10) rate during the imposed lockdown. We explore air quality change in Morocco's North-Western cities using the Copernicus Atmosphere Monitoring Service (CAMS) regional model that provides estimated emissions of pollutants into the atmosphere. The results show an apparent decrease in PM10 levels during the lockdown, which points out the impact of human activities on air quality. The ozone shows an increasing tendency, which is probably linked to improved photochemical reactions due to the rise of sunlight passing by the atmosphere, resulting in decreased PM concentrations. This period that the world is experiencing has drastically impacted socio-economic sectors, but it has proved that human activities are the main factor influencing the environment.
