Abstract:  The Equatorial Spread-F (ESF) is a complex phenomenon encompassing a wide range of scale sizes (covering more than six orders of magnitude) of irregularities in electron and ion densities as well as in electric fields. The generation mechanisms involve not only the plasma processes but also neutral processes. Thus, to understand the different facets of ESF manifestations, investigations have been carried out using multiple techniques. The research in this topic has practical implications as these irregularities affect the propagation of radio wave even in Ultra High Frequency band. Considerable amount of works have been done in India to understand this phenomenon. Some of the important results in the last three decades, as perceived by the authors, are reviewed in this paper. This involves results obtained from ground-based, rocket and satellite borne experiments conducted from India along with theoretical and laboratory simulations.
