Preliminary results of the on-going measurements of some atmospheric weather parameters in Akure (715’N, 512’E), South Western Nigeria are presented. The measurements were made using a Wireless Weather Station (Integrated Sensor Suite, ISS) positioned at the ground surface (0 m) at Iju in Akure North Local Government area of Ondo State. The study utilized the data for the first three years of measurement (2007-2009). From these measured parameters, atmospheric pressure, temperature and relative humidity were extracted and used to compute radio refractivity. The monthly mean of the temperature, relative humidity and the computed surface refractivity for the three-year period were also obtained. The variation of the surface refractivity with relative humidity (water vapour term) and with temperature were analyzed. The results obtained show that during the rainy season, refractivity has higher values. In the dry season on the other hand, refractivity has lower values.
