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 Advanced Composition Explorer (ACE) 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.
****ACE satellite data outages are affecting the real time part of this service. We are currently transitioning our interplanetary data source to NOAA's DSCOVR satellite. Sorry for your inconvenience.****
