GFE at NWRFCImpetus • New direction by NWS • Replacement for WR MM system • Collaboration • ISC capabilities • Expansion to other modeling • DHM
GFE at NWRFCMechanics • Mechanical Hurdles • Can GFE run at an RFC? • Initial distribution on DX1 • Performance issues/Compete with CPU resources • Grid Resolution/Domain size • PowerPC attached to AWIPS production • Stand Alone GFE • ATAN Site
GFE at NWRFC3-Phase Project • Experiment with Grids • GFE at an RFC? • PowerPC attached to AWIPS • Stand alone GFE • 3-Phase project • ATAN
GFE at NWRFCPhase I • Parallel with Legacy System • Mitigate Performance issues • Generate Precip/Temp grid and point data • Explore “Smart” Tool and Formatter Development • Demonstrate ISC capabilities • Verification • Emulate WFO verification • BOIverify
GFE at NWRFC • Emulate Current Legacy System Services • 10-day forecast Precip, Temp, Freeze Level • Day 1-3 & Day 4-10 • Forecast Production • Use Model Input - eg, GFS40, ETA12, DGEX • WFO Input - ISC • Blank screen • OR any mix of the above • Exercise ISC capabilities
GFE at NWRFC Precipitation 10 days - 6 hr steps • 2.5 km • 604x644=388976 grid cells • Point data • Precip • Temp (max/min) • Freeze Levels • Mean Areal Precip (phase 2) • Mean Areal Temp (phase 2) • 10 days • 6 hour time steps Temp(mx) 10.5 days - 6 hr steps
GFE at NWRFC • Daily Products • Formatters to SHEF encode
GFE at NWRFC • Spring 2006 used GFE as Supplemental tool during April Through June • Fall 2006 has GFE moving up quickly in priority as an operational tool • Used extensively during all event in Nov/Dec • Priority Change due to new HAS staff • GFE remains “supplemental” in operations.
GFE at NWRFCThe Other Phases • Phase 2 • Mean Areals directly from grid data • Apply PRISM techniques • Reverse ISC – Xmit RFC grids to WFOs… • Phase 3 • Operational? • Training?
GFE at NWRFCTo Be Accomplished or What to do to be Operational • Verification • Training • Meteorologist / Hydrologist • Probabilistic / Ensemble • Support • Hardware/Software • Enhancement
