Regional Assessment of Ozone across Nigeria, from 2005 to 2018 using NASAGIOVANNI Air Quality

Abstract

Nigeria is a developing country situated in West Africa. As a developing, country, it is experiencing critical problem such as insecurity, political,social and religious crisis to mention but a few. Nigeria is equally urbanizing very fast and as such is overwhelmed with problems emanating from urbanisation, industrialization and agricultural development. These anthropogenic encumberances grossly inhibitthe country from effectively paying attention toperennial problem like air pollution. Ground level ozone was studied from NASA Giovanni air quality platform from 2005 to 2018. Visualizations from this study, shows an indication of seasonal fluctuations of ozone. The highest annual concentration of ozone across Nigeria for the sampled years was observed in the year 2013, it recorded 269.7DU. Others years include 2015, 2014, 2008 and 2004 they recorded 268.69DU, 267.31DU, 267.19DU and 265.85DU respectively. The least annual concentations of 260.18DU and 260.22DU were recorded in the years 2007 and 2005 respectively. A short annual range of 9.52DU was observed for the sampled years. From this study ozone decreases in the dry season and peaks in the rainy season.
