Diurnal and Seasonal variations in troposphere ozone level at sub-tropical station, Jabalpur, India, and relationship with meteorological Condition (Published)
Troposphere ozone measurements at Central India sub tropical site Jabalpur (located at 23°10′N 79°57′E / 23.17°N 79.95°E) India has been studied for the period from January 2015 to December 2015.Tropospheric ozone is both a greenhouse gas and harmful air pollutant, it is important to understand how anthropogenic activities may influence its abundance and distribution through the 21st century. Ambient Air Quality Monitoring System (AAQMS) is sensor based ozone monitor which in used for measurement. Temperature shows a good positive correlation whereas relative humidity shows a negative correlation with ozone. Results of this study have revealed that the annual mean of daily average surface ozone concentration varies from 11 ppb to 38 ppb. The highest average seasonal concentration was observed in summer and lowest in winter season.
Variation of Metrological Parameters As They Affect the Tropospheric Radio Refractivity for Akure South-West Nigeria (Review Completed - Accepted)
This research work examines the effect of variations of meteorological parameters on the tropospheric radio refractivity during dry and raining seasons for Akure in 2013. The daily averages of radio refractivity during dry (January) and raining (August) seasons were calculated from the data obtained from the Nigeria Meteorological Agency (NIMET). The data that was used for the computation of radio refractivity is a daily interval of the variations of meteorological parameters for each day in the troposphere for Akure. Consequently, the daily averages of radio refractivity during raining season (August) were greater than the results in dry season (January) as a result of the variations in meteorological parameters such as temperature, humidity and atmospheric pressure in the lower troposphere
