Modelling Of Pressure-Altitude Equation Covering Up To 2km Above The Sea Level In Lagos, Southwestern Nigeria

Abstract

It is generally known that the atmospheric pressure varies inversely as altitude globally. In the absence of real time data, prediction of atmospheric pressure in the troposphere is based by the famous barometric equation which depicts exponential inverse relationship between these two variables. This work employed two years meteorological data of Lagos to study the relationship and model a localized equation. The research results show that the atmosphere is purely linear with a gradient of -10.1 m/hPa from the sea level to about 2 km. The modeled equation is useful for better prediction of atmospheric pressure for industrial, scientific and other purposes.
