Particle Size Analysis of African Dust Haze over the Last 20 Years: A Focus on the Extreme Event of June 2020

Over the last decades, impact of mineral dust from African deserts on human health and climate has been great interest to scientific community. In this paper, climatological analysis dusty events past 20 years in Caribbean area performed using a particulate approach. The focus is made June 2020 extreme event dubbed “Godzilla”. To carry out study, different types data were used (ground-based, satellites, model, soundings) several sites islands. First, magnitude was clearly highlighted satellite imagery. During peak event, value matter with an aerodynamic diameter less than 10 ??m (PM10) reached 9 times greater threshold recommended by World Health Organization one day. Thereafter, PM10, aerosol optical depth, volume particle size distribution analyses exhibited their maximum values for 2020. We also exceptional characteristics Saharan air layer terms thickness wind speed period. Finally, our results showed that more proportion 2.5 (PM2.5) PM10 increases, influence sea salt aerosols significant.
