AB  - In the design and frequency planning of microwave networks, propagation related parameters are used. During the ‘’clear sky’’ conditions, atmospheric refractive index is the important parameter that influences the propagation of radio waves. This study presents the results of the measurement of the basic physical parameters for the determination of radio refractivity. Meteorological sensors (Integrated Sensor Suite, ISS) are positioned at the ground surface and 150m above ground level for the measurements. From the result therefore, propagation conditions in this region are then classified as sub-refractive, normal, super-refractive and ducting.
