Abstract : The invention relates to real-time radio meteorological refractive index measuring systems and more particularly to a system and/or method for real-time determination of the initial radio refractive vertical gradient in the immediate atmospheric environment of the affected station site. The invention also relates to real-time application of the initial gradient to radio refraction error correction and to prediction of extended range radio propagation beyond normal line-of-sight.
