Global observations of E region plasma density morphology and variability The global morphology and variability of the ionospheric E region plasma density are estimated from satellite-based radio occultation total electron content (ROTEC) measurements. Vertical profiles of E region electron density are estimated using the inversion technique recently proposed by Nicolls et al. (2009). In this technique, the F-region contribution to each ROTEC measurement is removed using an assimilative model of the ionosphere in order to mitigate the effects of F-region gradients in the estimation of E region pro ...

Overview and summary of the Spread F Experiment (SpreadFEx) We provide here an overview of, and a summary of results arising from, an extensive experimental campaign (the Spread F Experiment, or SpreadFEx) performed from September to November 2005, with primary measurements in Brazil. The motivation was to define the potential role of neutral atmosphere dynamics, specifically gravity wave motions propagating upward from the lower atmosphere, in seeding Rayleigh-Taylor instability (RTI) and plasma bubbles extending to higher altitudes. Campaign measurements focused on the Brazilian ...

Incoherent and coherent scatter radar studies of the equatorial F region Radio waves are weakly scattered by thermal fluctuations in the quasiequilibrium ionospheric plasma. Coherent scatter echoes, meanwhile, are caused by non-thermal electron density fluctuations generated by plasma instabilities and are much stronger than incoherent scatter (IS) echoes. The spectra of IS echoes provide information about parameters of the background plasma such as electron density, temperatures, and ion composition. On the other hand, coherent scatter echoes provide an indication of the turbulent state of the i ... Published by: Published on: |
