COMPASS: A New COnductance Model Based on PFISR And SWARM Satellite Observations by Zihan Wang, Shasha Zou

“…In this work, a new model, COnductance Model based on PFISR And SWARM Satellite observations, describing the statistical relationships between conductance and field‐aligned currents (FACs) is presented. The conductance was calculated using the electron densities measured by Poker Flat Incoherent Scattering Radar (PFISR), and the FACs were determined by the magnetic perturbations measured by SWARM at Low‐Earth Orbit. …”

Thermospheric neutral wind studies over the equatorial region: A review by Siti Syazwani Nasuha, Idahwati Sarudin, Nurul Shazana Abdul Hamid, Ahmad Fairuz Omar

“…The low-latitude equatorial region in particular has been observed to exert complex influences on TNWs because of the unique effects of the Earth’s magnetic field at the dip equator. Studying neutral winds over this region will provide valuable insights into the unique dynamics and processes that occur in this region, thereby enhancing our understanding of their role in the overall dynamics of the TIS. …”
