Abstract
The Naval Research Laboratory (NRL) has recently developed a three-dimensional code to study equatorial spread F (ESF). The code is based on the comprehensive NRL 3D ionosphere model SAMI3 and includes a potential equation to self-consistently solve for the electric field. The model assumes equipotential field lines so a 2D electrodynamic problem is considered. Results are presented showing the evolution of atomic and molecular ions, as well as that of the electron and ion temperatures during ESF.
