Abstract

In order to obtain a reliable microwave link system, models that are location-dependent are to be developed with meteorological data from the location under consideration. Models and analytical data obtained based on data from another location with different climatological pattern often prove inadequate when adapted in another location. Therefore, in order to make prediction of attenuation attributed to water vapor and oxygen in the south-western part of Nigeria, development of mathematical model for water vapor and oxygen attenuation using Meteorological data (pressure, temperature and water vapor) for Lagos ( ,  for the range of five (5) years was developed in this research. Consequently, the newly developed models (gaussian, exponential and linear models) were applied to derive new analytical parameters in a wide frequency range frequency from K band, Ka band, X band, Ku band, S band and C band respectively for both the oxygen and water vapor in Lagos (south-west, Nigeria). The proposed model therefore, show significant improvement over the ITU-R model in terms of root mean square error (RMS) values.
