FDEWS Two-Dimensional Classification
DIMENSION 1: RISK LEVEL (Research classification)
🟢 NORMAL
Baseline probability
No elevated FD risk
🟡 ELEVATED
Increased probability
Monitor conditions
🔴 CRITICAL
High probability
Review contingencies
DIMENSION 2: EVENT STATE (Real-time classification)
🟢 QUIET
Space weather stable
Normal operations
🔵 FORECAST
CME detected
Event possible 24-72h
🟡 WATCH
Storm developing
Heighten monitoring
🔴 ACTIVE
FD in progress
Protective measures
🟣 RECOVERY
Conditions improving
Continue monitoring
These dimensions are independent. You can have elevated research risk while current conditions are quiet, or quiet research risk during a sudden disturbance.
Data Sources
FDEWS integrates real-time data from authoritative space weather services:
NOAA SWPC
Kp Index, Proton Flux, X-Ray Flux
Updated every 15 minutes
NASA DONKI
CME Detection & Analysis
Event-based updates
Oulu Neutron Monitor
Cosmic Ray Intensity
Hourly updates
DISCLAIMER: FDEWS classifies space weather risk conditions using proprietary analysis. It does not predict specific events. For informational and research purposes only. Past classification accuracy does not guarantee future results.
Not affiliated with NOAA, NASA, ESA, or government space weather services. Official forecasts should be obtained from NOAA SWPC.
