SEASONAL AND SUB-SEASONAL DISTRIBUTION OF AEROSOL TYPES OVER NIGERIA
Abstract
This study investigates the seasonal and sub-seasonal distribution of aerosol types over Nigeria. Nigeria experiences significant atmospheric pollution characterized by PM2.5, PM10, carbon monoxide (CO), black carbon (BC), and sea salt aerosols due to both natural and anthropogenic sources.
The research adopts a multi-platform observational approach integrating satellite data (MODIS, MISR), atmospheric models (CAM6-chem, MERRA-2), and ground-based monitoring systems. Data from 2000–2020 were analyzed across selected cities including Ikeja, Lokoja, Port Harcourt, and Warri.
Findings reveal strong seasonal patterns, with higher aerosol concentrations during the dry Harmattan period and lower concentrations during the wet season due to precipitation scavenging. The study highlights the impact of urbanization, industrial emissions, and trans-boundary dust transport on air quality in Nigeria.
