Relativistic Electron Forecast Model:


Relativistic Electron Forecast Model thumbnail

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

Electron alerts thumbnail
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.
