  2. FFMP Improvements (QPE/QPF Improvements) Outline • High-resolution Precipitation Estimation (HPE) (AWIPS OB8.3) • High resolution rain rate and precipitation accumulation grids • spatial resolution 1/4 HRAP mesh length (~1x1 km) • Update frequency configurable up to 5 minute intervals • DHR used to create radar rain rate estimates • Gages are NOT used in this version of EMPE, however the MPE gage-radar bias table can be used in rain rate and accumulation estimation • Dual Polarization DPR NOT used in this version of EMPE

  3. FFMP Improvements (QPE/QPF Improvements) Outline • High-resolution Precipitation Nowcaster (HPN) (AWIPS OB9.0) • An extrapolative forecast of the reflectivity field valid for the next hour, updated every 15 minutes on an HRAP grid. Additional fields for AWIPS display include: • 1-hour radar precipitation accumulation forecast (with and without bias correction) • Instantaneous rain rate forecasts at 15 minute intervals out through 1-hour (with and without bias correction) • RFC MPE Mean Field Bias to WFO (AWIPS OB8.2) • WFO operators can select which RFC bias message to receive and which bias message to send to the RPG • NMQ/Q2 infusion into NCEP (no targeted build) • Probabilistic QPE (no targeted build)

  4. FFMP Improvements OB8.3 Improvements Outline • Ingest gridded data (QPE, QPF, and guidance)

  5. FFMP Improvements OB8.3 Improvements Outline • Attribute Inclusion in the Basin Trend Table

  6. FFMP Improvements OB8.3 Improvements Outline • Split Window QPF

  7. FFMP Improvements OB8.3 Improvements Outline • On the fly CWA coverage

  8. FFMP Improvements OB8.3 Improvements Outline • Enhanced Basin Trend

  9. FFMP Improvements OB8.3 Improvements Outline • Site Controlled Time Window Maximum • Uses purge value from AWIPS Intelligent Purger • Increase in number of monitor sites • From 3 to 5 • Localization containment • Separate from SCAN • Enhanced Displaced Real-Time (DRT)

  10. FFMP Improvements OB9 Improvements Outline • Fixed Duration Basin Trend Graphs

  11. FFMP Improvements OB9 Improvements Outline • Fixed Duration Basin Trend Graphs

  12. FFMP Improvements OB9 Improvements Outline • FFG Updating

  13. Must obtain, customize and VERIFY new domain based small basin files Improving Flash Flood Services WarnGen OB8.3 Outline • FFMP Basin names in WarnGen
