“…Present study is different from that of the study of other researcher (Bhuyan et al, 2002(Bhuyan et al, , 2004(Bhuyan et al, , 2006Aggarwal et al, 2009) in various aspects using the same satellite data set. Aggarwal et al (2009) chose the data only for sunrise period for the equatorial region from 10°S to 20°N.…”

“…Another advantage of SROSS-C2 mission is that the orbit is just above the F-region electron density peak and the orbital ellipticity is much less. Many researchers (Bhuyan et al, 2002(Bhuyan et al, , 2004(Bhuyan et al, , 2006Aggarwal et al, 2009) have also used the SROSS-C2 satellite data to study the behavior of ionospheric parameters. Bhuyan et al (2004) studied the diurnal, seasonal and latitudinal variations of the ion temperature using the SROSS-C2 satellite data in the Indian zone equatorial and low latitude ionosphere at an average altitude 500 km.…”

“…This region was chosen on the basis of maximum passes of SROSS-C2 over India. Bhuyan et al (2004Bhuyan et al ( , 2006 have chosen the same study region as that by Aggarwal et al (2009) to study the diurnal, seasonal and latitudinal variations of electron and ion temperatures.

In the topside ionosphere during the daytime, the thermal electrons are directly heated by photoelectron fluxes from the local and conjugate hemispheres. The heat is lost primarily through conduction to the regions below where collisions with the ions provide the cooling. Ions are heated by collisions with both the electrons and ions and are cooled primarily by conduction to lower altitudes where the heat is lost to collisions with the neutral gas. Here we examine the effects of ion composition on the ion and electron temperatures in the midlatitude topside ionosphere during daytime using data from the Defense Meteorological Satellite Program F15 satellite in 2004–2006. The variations of electron and ion temperature with plasma density and composition indicate how the heat is exchanged between the different constituent ions and the role played by the solar zenith angle and the solar ionizing flux (F10.7). The observations show that the daytime temperature difference between the O+ and electron is smallest when the fractional contribution of H+ is the highest. In such an environment the electrons transfer heat to the H+ then to the O+ through ion‐ion collisions.

Storm time meridional wind perturbations in the equatorial upper thermosphere

[1] We present observations from the Coupled Ion Neutral Dynamics Investigation (CINDI) of storm time meridional winds in the neutral atmosphere near the magnetic equator at 400 km altitude. Observations near the magnetic equator in the southern geographic hemisphere are dominated by energy inputs from the southern Polar Regions that produce south to north (equatorward) wind perturbations to accompany perturbations in the neutral density and temperature. In one exceptional case, when observations are made near midnight and the north magnetic pole rotates through the midnight sector, north to south (poleward) meridional wind perturbations are observed just south of the magnetic equator. Accompanying perturbations in the neutral density on the dayside and the nightside are consistent with observed increases in the ion temperature and inferred increases in the neutral temperature in accord with hydrostatic equilibrium.
