CCMC Functions Transition to Ops
Decision makers and operational agencies need
model evaluations - Science-based validation
Compare model output to measurements for select
events, detailed analysis - Metrics studies
Repeatable comparison between model output and
measurements, one number Need to be blind
studies, performed by independent agent

VV Software Predicting MeV Electron Intensity

• Evaluated model
• Software predicting MeV electron intensity at
  the geostationary orbit
• Developed at APL/UPOS
• Input real-time ACE data
• Output polar cap potential
• Considered for operations at AFWA

• Quiet vs stormy period
