A meridional scanning OI 630.0-nm dayglow photometer was operated from Ahmedabad (17.2°N dip lat.) scanning a region towards the south in the upper atmosphere extending over ~5° in latitude from 10.2°N to 15.2°N dip latitude. From the spatial

We review the observational evidence for describing the characteristics of the equatorial temperature and zonal wind anomaly (ETWA) in the low-latitude thermosphere in solar maximum and minimum periods. In spite of some new results on ETWA in the las

The recent observations on the small-scale irregularities in the equatorial E region from locations other than those from the close vicinity of the electrojet (EJ) centre are reviewed. In particular, the diurnal characteristics of irregularities at l

In order to understand the recent radar observations of rising structures in the plasma densities in the upper E-region during nighttime at equatorial and low latitude stations, an investigation is made to explore the possible relation between the E-

We show evidence for the occurrence of the equatorial temperature anomaly (ETA) during solar minimum by analyzing the temperature and total ion density data from the Neutral Atmosphere Temperature Experiment (NATE) and the Cylindrical Electrostatic P

Results from coordinated measurements of OI 630.0 nm dayglow intensities (centered on ∼220 km altitude), along with VHF (50 MHz) coherent backscatter returns from Thiruvananthapuram, a dip equatorial station in India, revealed that the temporal var

The Equatorial Spread-F (ESF) phenomenon is recorded in ionograms as a hierarchy of plasma instabilities in the F-layer of the equatorial ionosphere. The ESF is characterized by irregularities in the plasma (electron and ion) density and electric fie

The theory of equatorial electrojet predicts the presence of vertical ion currents (Pedersen currents) as a part of the electrojet current system. The vertical ion current density profile over the dip equator, that forms a part of the meridional curr

We describe the average and apparent local (solar) time (LST) variations in the zonal winds (Z) and temperatures (T) as measured with the Wind and Temperature Spectrometer (WATS) on-board the polar orbiting DE-2 satellite in the altitude range of 300
