Existence of an additional layer in equatorial ionosphere: Other observations
In this paper we present an observation of an additional layer over the Malaysian ionosphere using bottomside sounding. This F3 layer has been observed over Brazil by Balan et al. (1995). Other work done by Uemoto et al. (2004) from the observation of topside sounding obtained by the Ohzora satellit...
