LiMIE: Linear Modeling of Ionospheric Electrodynamics


Select version of the IZMIRAN Electrodynamic Model:

Enter time interval and interplanetary magnetic field (IMF) parameters:
Year
Month
Day
UT Hour
Minute

IMF Bx
IMF By
IMF Bz
Enter contour interval
(automatic selection = 0)

Select parameter to model and coordinate system to plot:

Warning: Do not forget changing selection to "Electric Potentials" if "DMSP Ionospheric Convection Model" is selected above. Note that either of the modeled parameters can be selected for both "IZMEM" models.

Ørsted+Magsat Field-Aligned Currents Model produces patterns obtained purely from the new, satellite-based model of field-aligned currents [Papitashvili et al., 2002].

DMSP Ionospheric Convection Model produces patterns obtained purely from the new, DMSP-based model of ionospheric electrostatic potentials [Papitashvili and Rich, 2002].

IZMEM - calibrated by DMSP potentials produces patterns obtained after recalibration of the IZMEM model by the observed DMSP electrostatic potentials [Papitashvili et al., 1999].

IZMEM - from ground magnetometers produces modeled patterns obtained from the analysis of ground-based magnetometer data [e.g., Feldstein and Levitin, 1986, Papitashvili et al., 1994, and references therein].

While the modeling of any ionospheric parameter in the CGM Lat - MLT coordinates requires less than 5 sec on this Web server, it takes up to 1 min to calculate the plot in geographic coordinates... so, be patient! Also, we suggest the model be run first in the CGM Lat - MLT coordinates to select the appropriate contour interval.
