Model Diagnostic Discussion

The Model Diagnostic Discussion NFDPMDHMD is issued daily at 0530Z &  1730Z.  It describes performance attributes of at least the GFS and Eta model for the most recent 00Z or 12Z run.


Model Verification

The links below allow you to ascertain how well a model forecast has verified as a function of forecast hour, cycle, and field.

EMC/WPC/MPC/NCO Synergy Meeting Highlights

Meetings between NCEP EMC, NCO, and NCEP Operational centers are held routinely to discuss short term implementation plans of the models in concert with super computer and communication system development.  Operational feedback from users is incorporated into these plans.
