Fine particulate air pollution estimation in Ouagadougou using satellite aerosol optical depth and meteorological parameters

Abstract

The main sources of fine particles in our cities are the exhausts of cars, trucks, buses, and offroad vehicles as well as other processes that involve the burning of fuels like wood, heating oil, or coal, and natural sources like dust storms from the Sahara Desert and forest fires. Fine particles tend to worsen conditions such as asthma, and other forms of respiratory diseases. Since the sources of these particles are a result of our daily activities it is urgent to measure their levels so we can plan outdoor activities safely and reduce their impact on our health. This work used satellite and weather information to develop four (4) models to help estimate Ouagadougou’s fine particles as a way of contributing to solving air pollution problems in African cities. The photo proves the sources of fine particles in the city of Ouagadougou and how residents breathe them without wearing air filters/nose marks.
