Measurements of the Radio Refractive Index Structure Parameter C2n with a Microwave Refractometer in Tropical Latitudes

Abstract

The spatial and temporal variations of the radio refractive index lead to scattering of electromagnetic energy. Modern communication systems are subject to vagaries of the turbulence due to the radio refractive index fluctuations. Vertical esolution of radiosondes is insufficient to resolve the structures of clear air turbulence in the atmosphere. In a tropical ountry like India, aircraft measurements of radio refractive index fluctuations have been non-existent. refractivity, has a lower value in local winter than in summer.
