    14-Years Aerosol Fingerprint Impact and Implications Over Daloa in Western Ivory Coast
    (2019) Emetere ME; Okoro EE; Sanni SE
    This study reports the trend and impact of aerosol loading over Duola from 2000 – 2013 using aerosol optical depth (AOD) data obtained for particulate matter in the region. The dataset was obtained from the Multi-angle Imaging Spectro-Radiometer (MISR). The secondary datasets that were generated from the primary data were aerosol loading, particles sizes, Angstrom parameter and the statistics of the primary dataset. We observed from the primary dataset that the aerosol loading values for the years under consideration varied but higher values were recorded in the years 2000 and 2007-2013. These high aerosol depths informed high aerosol concentrations over Duola from October through May. Years of high aerosol concentrations in the atmosphere were potential threats to human health; with high concentration of aerosol particles, the government should adopt and implement stricter environmental policies to reduce the industrial and human contributions to these air pollution. The Angstrom values calculations over the years were less than 1, thus, the aerosol particle size indicates size distributions dominated by coarse mode aerosols.

    Air pollution assessment: a preliminary study towards citing industry
    (2019) Emetere ME; Okoro EE; Adeyemi GA; Sanni SE
    The spate of increased air pollution in the study area is a source of concern. In this research, we examine the spatial distribution of atmospheric aerosol and its danger to the life form that resides therein. Fifteen years primary (aerosol optical depth) dataset was obtained from the Multi-angle Imaging Spectro-Radiometer (MISR). The secondary datasets that was generated from the primary data were aerosol loading, particles sizes, Angstrom parameter and the statistics of the primary dataset. It was observed that if not controlled, the life form in the research area may be under unimaginable danger in the near future. Hence, industrialization projects would require the dataset for environmental assessment before citing industry in the geographical area.

    Effect of atmospheric aerosol on corrosion of metallic surfaces
    (2019) Emetere ME; Okoro EE; Akinlabi ET; Sanni SE
    This research investigates the impact of atmospheric aerosols to initiate atmospheric corrosion of metallic surfaces. Fifteen years’ primary (aerosol optical depth) dataset was obtained from the Multi-Angle Imaging Spectro-Radiometer (MISR). Aerosol loading were generated from the primary dataset. The component of the atmospheric aerosols was obtained from existing literature. A mathematical projection on the corrosion of metallic surfaces was done using spatial maps and secondary dataset. The yearly corrosion rate has doubled since 2004. Higher accuracy of the modified Faraday model can be achieved using ground dataset.
