Modelling particulate matter (PM2.5) source contributions for air pollution management in Addis Ababa, Ethiopia
Ground measurements and satellite observations over Addis Ababa airshed show a deteriorating trend of air pollution, especially for PM2.5 (all particulate matter under 2.5 μm). In this paper, we present a review of available monitoring data; a model-ready multi-pollutant (PM10, PM2.5, SO2, NOx, CO,...

| description | Ground measurements and satellite observations over Addis Ababa airshed show a deteriorating trend of air pollution, especially for PM2.5 (all particulate matter under 2.5 μm). In this paper, we present a review of available monitoring data; a model-ready multi-pollutant (PM10, PM2.5, SO2, NOx, CO, non-methane VOCs, and CO2) emissions inventory at 0.01° resolution for the designated airshed; a heatmap of PM2.5 concentrations and an estimate of source contributions constructed using WRF-CAMx chemical transport modelling system; and a discussion on proposed actions towards establishing an air quality management plan for the city. Emissions from road transport; residential and commercial cooking; resuspended dust on roads and from construction activities; residential and industrial heating; open waste burning; and other industrial activities contributed to annual average ambient PM2.5 pollution levels ranging 20–60 μg/m3. Particularly, vehicle exhaust is estimated to contribute up to 29 % of total PM2.5, followed by biomass combustion in the residential and industrial sectors. |
