Abstract
Attenuation by water vapor and oxygen is one of the major reasons electromagnetic waves in some frequency bands get degraded. It is of key importance to study, understand and mitigate these effects as much as possible. In this work, hourly attenuation due to water vapor also known as wet attenuation as well as attenuation due to oxygen, known as dry attenuation in decibel per kilometer was calculated for the Ka, Ku and V frequency bands. The International Telecommunications Union‐676 model was used to calculate these values using 60 seconds integration time measured values of Pressure, Temperature and Relative humidity. These parameters were obtained from the Covenant University Davis‐Pro Automatic weather station installed in Ota, Nigeria. The computed results between April and December 2012 are hereby presented.
