A Study of M Profiles for Some Stations Near Western Coast of India

A study of modified refractive index profiles derived from radiosonde data relating to four stations located near the Western Coast of India has been made. Structure of some of the profiles and statistics of occurrence of M-inversions over these stations are given. Average monthly variation of Radio refractive index and its diurnal change near the ground surface and at certain fixed isobaric levels have also been described
