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

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)
