The atmosphere of southern West Africa (SWA) is one of the world’s most aerosol-laden regions. This study investigated the seasonal variability of aerosol optical thickness using photometric and CALIPSO/CALIOP observations. The mean daily aerosol o

Stack emissions from the industrial sector are a subject of concern for air quality. However, the characterization of the stack emission plume properties from in situ observations remains a challenging task. This paper focuses on the characterization

The physico-chemical characteristics of particulate matter (PM) in African cities remain poorly known due to scarcity of observation networks. Magnetic parameters of PM are robust proxies for the emissions of Fe-bearing particles. This study reports

Due to a limited number of monitoring stations in Western Africa, the impact of mineral dust on PM10 surface concentrations is still poorly known. We propose a new method to retrieve PM10 dust surface concentrations from sun photometer aerosol optica

According to the European Environmental Agency, industrial fine particles emissions have represented respectively 15% and 6.5% of PM10 and PM2.5 emissions in Europe between 2013 and 2018. Stack emissions are a significant contributor to the atmospher

Particulate emissions from industrial sector are a concern for human health and air quality. In this paper we investigate the use of a hyperspectral image to retrieve plume mass concentration and its flow rate from the plume optical properties. The m
