Abstract: I will talk about a new study of equatorial magnetospheric electron density, mass density, and average ion mass in the plasmasphere and plasmatrough between L = 3 and L = 10. Data from the CRRES, Polar, and Van Allen Probes spacecraft were used. Using a model for the electron density at the midpoint of the plasmapause, we separated observations into plasmasphere and plasmatrough regions. Electron density was found from plasma wave data, and mass density from the frequencies of Alfven wave eigenmodes. The nonlinear genetic regression program TuringBot was then used to generate analytical models for these quantities as a function of position in space, phase of the solar cycle as specified by the solar EUV radiation, and geomagnetic activity as indicated by various indices such as Kp and AE.
