This page displays verification statistics for the official evaluation of the Rapid Refresh (RAP) version 5 and the High Resolution Rapid Refresh (HRRR) version 4. The RAPv5/HRRRv4 Official Evaluation is scheduled for October-December 2019.
The RAP is the continental-scale, hourly-updating data assimilation and numerical modeling system run operationally at the National Centers for Environmental Prediction (NCEP). North American RAP forecasts are complemented by hourly-updating forecasts from the HRRR model, which is run at higher resolution covering CONUS and Alaska domains.
The RAPv5 and HRRRv4 realtime parallels being run at NCEP/EMC are compared to their respective operational counterparts, RAPv4 and HRRRv3. Verification for RAPv5 and HRRRv4 retrospective forecasts is also provided courtesy of ESRL/GSD.
