Ion and electron temperatures in the topside ionosphere
… theoretical ion and electron temperatures in the topside ionosphere are investigated. Experimental results come from an analysis of incoherent-scatter data taken at Arecibo, Puerto Rico. Consideration of the energy balance equations gives the theoretical ion and electron temperatures. Two ions, 0+ …

Ion-Cyclotron Resonance Heating of O+ in the Topside Ionosphere and Mapping Outflows to the Magnetosphere
… place in the turbulent region of the Earth’s topside, high latitude ionosphere. We simulate the impact of this transverse heating process upon energies and velocity distribution functions of outflowing oxygen ions (O+) in the approximate altitude range of 800 km to 15,000 km. To do so most …

Auroral Ion Upflows: Sources, High Altitude Dynamics, and Neutral Wind Effects
… are commonly observed in the high-latitude, topside ionosphere. These auroral ion upflows have a range of potential sources including frictional heating, electron precipitation, neutral winds, and higher-altitude density cavities. The unique signatures and detailed evolution of these upflows …

Full-profile inversion of ionospheric radar data from Arecibo observatory
… radar (ISR) technique is used to probe the ionosphere and measure the key state parameters of the ionosphere in thermodynamic equilibrium, including its electron density, ion densities and compositions, electron and ion temperatures, and the associated drift velocities of ionospheric …

Kinetic Modeling of Ionospheric Outflows Observed by the VISIONS-1 Sounding Rocket
<p>Plasma escape from the high-latitude ionosphere (ion outflow) serves as a significant source of heavy plasma to magnetospheric plasma sheet and ring current regions. Outflows alter mass density and reconnection rates, hence global responses of the magnetosphere. The VISIONS-1 (VISualizing Ion …

Impacts of Anisotropy, Wave Heating, and Neutral Winds on High-Latitude Ionospheric Dynamics
… for six ion species important to the E-, F-, and topside ionospheric regions: O+, NO+, N+ 2 , O+ 2 , N+, and H+. Electrons have also been included using an isotropic description. The effects of photoionization, electron impact ionization, wave particle interactions and chemical and collisional …
