SEPSTER
AvailableSEP prediction derived from STEReo observations — the original empirical model relating peak proton intensity to CME speed and the observer's magnetic connectivity.

CLEAR Center forecasting tools
Operational products and prototypes delivered by the CLEAR Center, organized by modeling paradigm. Links to live instances appear on each card as the tools come online.
Empirical models
Empirical models
Fast, interpretable models relating eruptive-event observables directly to SEP properties.
SEPSTER (2D)
AvailableTwo-dimensional extension of SEPSTER that relates peak proton intensities and spectra to the speed and direction of the associated CME relative to the observer's magnetic footpoint — providing longitudinally-resolved empirical predictions.
Launch tool →SEPSTER-EPAM
Coming SoonEmpirical SEP prediction driven by in-situ particle measurements from the EPAM (Electron, Proton, and Alpha Monitor) instrument, complementing the CME-driven SEPSTER family with a particle-data-based signal.
AI / ML models
AI / ML models
Machine-learning models trained on decades of SEP, CME, and flare data — extending forecasts into the pre-eruption phase.
SEPNET
AvailableMachine-learning SEP forecast model. Run the live SEPNET app on the Michigan Space Weather Machine-Learning Portal.
Launch tool → Physics-based models
Physics-based models
Global simulations from the solar corona through the inner heliosphere, providing the background state and magnetic connectivity for every SEP forecast.
SOFIE
Coming SoonPhysics-based SEP simulation tool integrating a full modeling pipeline — from CME initiation through shock-driven particle acceleration and interplanetary transport.

AvailableDaily background solar-wind solution driven by GONG magnetograms through the Alfvén Wave Solar-atmosphere Model (AWSoM-R).
Launch tool →Real-time Solar Wind
AvailableContinuously updated background solar-wind module, refreshed as new near-real-time magnetograms arrive — the substrate that all other CLEAR physics modules plug into.
Launch tool →Magnetic Connectivity
AvailableMagnetic connectivity maps between the solar surface and any point in the inner/middle heliosphere, built on the Stream-Aligned MHD (SA-MHD) method — critical input for every SEP forecast.
Launch tool →Forecasting gaps
Five forecast products still missing from operations
NASA's Space Weather Science and Measurement Gap Analysis identifies five concrete SEP forecast products that current operations cannot reliably deliver. CLEAR's tools advance each of them.
1
Pre-eruption probabilistic forecasts
Predict the likelihood of an SEP event before the eruption occurs, from active-region magnetic-field and coronal observations.
2
Onset-time prediction
Forecast when energetic particles will arrive — currently limited by the very short lag between solar eruption and particle arrival.
3
Time–intensity profiles
Predict the full rise–peak–decay profile of an event, not just the peak flux.
4
Spectral characteristics
Forecast the energy spectrum of an event, not just a single integrated intensity.
5
All-clear windows
Issue high-confidence all-clear forecasts so operations can schedule EVAs and launches around SEP events.

Research to operations, operations to research.
CLEAR tools are delivered to the Community Coordinated Modeling Center (CCMC) for community access, and feedback from operations feeds directly back into the Center's research program. For collaboration inquiries, contact the center.
