Název v původním jazyce

Latitudinal variation of the topside electron temperature at different levels of solar activity

Popis výsledku v původním jazyce

A database of electron temperature (Te) measurements comprising most of the available satellite measurements in the topside ionosphere is used for studying the solar activity variations of the electron temperature Te at different latitudes, altitudes, local times and seasons. The Te data are grouped into three levels of solar activity at four altitude ranges, for day and night, and for equinox and solstices. In general Te changes with solar activity are small and comparable in magnitude with seasonal changes but much smaller than the changes with altitude, latitude, and from day to night. In all cases, except at low altitude during daytime, Te increases with increasing solar activity. But this increase is not linear as assumed in most empirical Te models but requires at least a parabolic approximation. At 550 km during daytime negative as well as positive correlation is found. Our data base allows to quantify the latitude range and seasonal conditions for which these correlations occur
