CARBON MONOXIDE LEVELS IN THE CITY OF KANO AND BENIN CITY USING SENTINEL 5P SATELLITE DATA 2020-2022

ABSTRACT

Carbon monoxide is a harmful pollutant emitted from various sources, including industrial processes, transportation and biomass burning. In this study sentinel 5p satellite data was used to assess the levels of CO in the atmosphere in the city of Kano and Benin City. The raster data was obtained from the sentinel 5P satellite data and analyzed in the ArcGIS version 10.4 environment. This study was carried for three years (2020-2022) taking the data quarterly for the study areas. In the study, Kano city had a mean CO concentration value of 0.04315109 mol/m2 from January to April, 2020; 0.036909405 mol/m2 from May to August 2020 and 0.035296314 mol/m2 from September to December, 2020. The mean CO concentration value of Kano city was 0.04074702 mol/m2 from January to April, 2021; 0.036503226 mol/m2 from May to August 2021 and 0.034416388 mol/m2 respectively from September to December, 2021. The mean CO concentration value of Kano city was 0.041459019 mol/m2 from January to April, 2022; 0.036622254 mol/m2 from May to August 2022 and 0.032341093 mol/m2 respectively from September to December, 2022. Benin City had a mean CO concentration value of 0.066431988 mol/m2 from January to April, 2020; 0.044720803 mol/m2 from May to August 2020 and 0.046107234 mol/m2 from September to December, 2020. The mean CO concentration value of Benin City was 0.06053185 mol/m2 from January to April, 2021; 0.044725682 mol/m2 from May to August 2021 and 0.44593833 mol/m2 respectively from September to December, 2021. The mean CO concentration value of Benin City was 0.061789661 mol/m2 from January to April, 2022; 0.04292625 mol/m2 from May to August 2022 and 0.043659049 mol/m2 respectively from September to December, 2022. Monitoring of air quality emission and controlling the air quality is a good way to reduce CO concentration levels.
