RAPID REFRESH FORECAST SYSTEM (RRFS)

The Rapid Refresh Forecast System (RRFS) is the NOAA next-generation convection-allowing, rapidly-updated prediction system.
The operational configuration will feature a 3-km grid covering North America with both deterministic and ensemble forecasts.
The RRFS is underpinned by the Unified Forecast System (UFS), a community-based Earth modeling initiative, and benefits from
collaborative development efforts across NOAA, academia, and research institutions.
