Magnetospheric Energetic Electrons

Relativistic Electron Forecast Model:
Product Description:
Predicted daily fluence of radiation belt electrons (>2 MeV) at geostationary orbit over the next one, two, and three days. Also indicated on the product are previously predicted and observed fluencies over the past 25 days.

Target Users: Product users include the satellite industry, due to the impacts of enhanced radiation belt levels on satellite systems.

Relativistic Electron Forecast Model
Cadence: Daily
Data Source: Solar Wind Speed and GOES Electron measurements

Current Relativistic Electron Alerts
Product Description:
Timeline of currently active and recent radiation belt electron alerts. Alerts are issued when observed relativistic electron (>2 MeV) flux levels at geostationary orbit exceed 1000 particles/(cm2 s sr).

Target Users: Product users include the satellite industry, due to the impacts of enhance radiation belt levels on satellite systems.
