Real-time model of the Ionospheric Electric Fields
|Real-time Electric field
Transfer function model
Data & processing
The equatorial ionospheric eastward electric field (EEF) is predicted on a real-time basis using the solar wind data from the Deep Space Climate Observatory (DSCOVR) satellite. The web application can also be used to calculate the EEF for all longitudes from 01-01-1995 to present. The web application uses a transfer function model to predict the EEF variation from solar wind data and a climatological model to account for the quiet day variations of EEF. More details of the model and data processing are available with the links on the left side.
Update. The prompt-penetration model now uses the Advanced Composition Explorer (ACE) satellite data since DSCOVR spacecraft has entered into "safe-hold" starting June, 2019.
