PM_2.5 and PM₁₀ during COVID-19 lockdown in Kuwait: Mixed effect of dust and meteorological covariates.

ABSTRACT: This study investigated the impact of COVID-19 lockdown on particulate matter concentrations, specifically PM_2.5 and PM₁₀, in Kuwait. We studied the variations in PM_2.5 and PM₁₀ between the lockdown in 2020 with the corresponding periods of the years 2017-2019, and also investigated the differences in PM variations between the 'curfew' and 'non curfew' hours. We applied mixed-effect regression to investigate the factors that dictate PM variability (i.e., dust and meteorological covariates), and also processed satellite-based aerosol optical depths (AOD) to determine the spatial variability in aerosol loads. The results showed low PM_2.5 concentration during the lockdown (33 μg/m³) compared to the corresponding previous three
