Abstract

The investigation of day to day and seasonal tropospheric radio refractivity variation was carried out in Lagos using a three year period (January 2014 to December 2016) surface data. The data were collected using Campbell scientific automatic weather instrument. The CR1000 data logger type is used for measurement, and data storage is for five minute update cycle. The results of the analysis show that the high value of refractivity observed in the dry season can be attributed to the presence of water vapor in the air that causes evaporation from the Atlantic Ocean that covers the entire area. It was also revealed that the variation of refractivity in Lagos is mostly influenced by the variation of temperature and pressure with little contribution of relative humidity.
