Study of global distribution and solar activity variation of ionospheric ion temperature
Original language description
Since the mid-sixties, a substantial data base of in-situ thermal plasma parameters has been obtained. However,nmeasurements of ion temperature (Ti) were much less abundant than measurements of other parameters (e.g., electronndensity, electron temperature, ion composition etc.). This is one of the reasons why progress in developingna reliable empirical model of ion temperature has been much slower than for the other parameters. The IRI (InternationalnReference Ionosphere) model derives ion temperature from the energy balance equation among ions,nelectrons and neutrals.nWe have re-assessed ion temperature data from older satellite and combined them with newly available data fromnDMSP, C/NOFS and others (available primarily from SPDF: https://spdf.gsfc.nasa.gov/pub/data/) into a joinedndata-base. This data-base has been used in our study to establish global patterns of the ion temperature and tondetermine Ti variation with solar activity. To better understand the solar activity variations of ion temperature atndifferent latitudes and local times we have used simulations with the Field Line Interhemispheric Plasma flown(FLIP) model. The goal is to significantly improve the representation of Ti in the IRI model.
