Summary:
A four-year research program is proposed to study the electrodynamics of plasma instabilities
that develop in the nighttime equatorial ionosphere and can lead to the onset of equatorial
spread F (ESF). Understanding and modeling ESF is important because of its impact on
space weather: the associated electron density irregularities can scintillate radio wave signals
which can adversely impact communication and navigation systems. The primary scientific
objective is to address the question, what is the electrodynamic nature of equatorial
F region plasma instabilities? In particular we will investigate the difference between
two-dimensional and three-dimensional electrodynamic effects on the onset and evolution of
equatorial instabilities. This study will combine the 3D electrodynamics model developed
at Cornell University with the Naval Research Laboratory (NRL) ionospheric codes SAMI3
and SAMI3/ESF.
To achieve closure we will continually compare model results to data (e.g., radar measurements, in situ satellite data) to assess the validity of the model results
for explaining ESF day-to-day variability.
The proposed research directly addresses several objectives of the Living With a Star Targeted Research and Technology Focused Science Topic "Low- to Mid-Latitude Ionospheric
Irregularities and Turbulence" by improving models of F region plasma instabilities, quantifying the role of E and F region coupling on these instabilities, and understanding the
connection between large-scale ionospheric processes and the development of electron density irregularities.
