MODEL PERFORMANCE STATISTICS
The Environmental Modeling Center continuously
monitors its NWP model performance against different performance measures,
and against its 'competition' from other global forecast centers.
The following web links offer graphics of these performance measures at
various time and space dimensions. Click on the following links to
