Abstract :
The estimation performance of radio communication and radar propagation with high degree of accuracy is possible provided the results of radio environment are also available with good degree of accuracy. There are advancements on such results both for ionized and non ionized media due to the availability of sophisticated and computer controlled with data archive facility systems. Measurements of various both ionospheric and tropospheric parameters have been carried out as well as deduced by using various such measuring systems. In this presentation the research efforts carried out in recent years in India both in relation to studies on ionospheric dynamics for ionospheric communication and radio climatology both for clear air and precipitation, propagation characteristics involving fixed (terrestrial line of sight and over the horizon) and mobile and marine communication as well as attenuation of radio wave due to water vapour, rain and cloud in the area tropospheric communication have been highlighted.
