Variations of daytime and nighttime electron temperature and heat flux in the upper ionosphere, topside ionosphere and lower plasmasphere for low and high solar activity

Original language description

A database of the electrontemperature(Te) comprising of most of the available LEO satellite easurements is used for studying the solar activity variations of Te. The Te data are grouped for two levels of solar activity, five altitude ranges between 350 and 2000km, and day and night. By fitting a theoretical expression to the Te values we obtain variation of Te along magnetic field lines and heat flux for. We have found that Te increases with increase in solar activity at low and mid-latitudes during nighttime at all altitudes studied. During daytime the Te response to solar activity depends onlatitude, altitude, and season.This analysis shows existence of anti-correlation between Te and solar activity at mid-latitudes below 700 km during the equinox and winter day hours. Heat fluxes show small latitudinal dependence for day time but substantial for nighttime.
