Coincident Observations by the Kharkiv IS Radarand Ionosonde, DMSP and Arase (ERG) Satellites, and FLIP Model Simulations: Implicationsfor the NRLMSISE-00 Hydrogen Density, Plasmasphere, and Ionosphere
Original language description
This paper reports the results of ionosphere and plasmasphere observations with the Kharkiv incoherent scatter radar and ionosonde, Defense Meteorological Satellite Program, and Arase (ERG) satellites and simulations with field line interhemispheric plasma model during the equinoxes and solstices of solar minimum 24. The results reveal the need to increase NRLMSISE-00 thermospheric hydrogen density by a factor of similar to 2. For the first time, it is shown that the measured plasmaspheric density can be reproduced with doubled NRLMSISE-00 hydrogen density only. A factor of similar to 2 decrease of plasmaspheric density in deep inner magnetosphere (L approximate to 2.1) caused by very weak magnetic disturbance (D-st > -22nT) of 24 December 2017 was observed in the morning of 25 December 2017. During the next night, prominent effects of partially depleted flux tube were observed in the topside ionosphere (similar to 50% reduced H+ ion density) and at the F2-layer peak (similar to 50% decreased electron density). The likely physical mechanisms are discussed.
