Outline
FFMP Improvements (QPE/QPF Improvements)
  • 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

Outline
FFMP Improvements (QPE/QPF Improvements)
  • 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)
