RTMA/URMA/RTMA-RU v2.8

PCPANL 3.2

Upgrade scheduled to be implemented in Winter 2020

RTMA/URMA/RTMA-RU Planned changes :

• Similarity Theory/Boundary layer scheme for winds
  • New fixed files, new fields from smartinit necessary taking more space
• Expand wave height analysis to Great Lakes (CONUS) and Guam
  • Minimal size increases
• New variable in RTMA-RU: Sky Cover
  • File size increases, still meet the requirement of 15-minute product latency
• Finer grid in PR (only)
  • 2.5 km -> 1.25 km

PCPANL Planned changes :

• Add NOHRSC 6h/24h snowfall analyses to pcpURMA
• Introduce a smoother offshore filling of pcpURMA (blending at CMORPH/MRMS and MRMS/Stage IV boundaries)
• Use radar-estimated MRMS QPE in lieu of early Stage II/Stage IV for pcpRTMA; discontinue Stage II production (erly/mid/late runs for ST2ml, ST2gg, ST2rd, ST2un)
• Stage IV analysis changing from GRIB1 to GRIB2
• Discontinue use of “specialty” wgrib2/wgrib2 library (API dependence in source code)
• Add an additional run at 18Z cycle for 24h Stage IV accumulation (30h after valid time, to supplement the current 1/2/3/5/7-day re-run schedule, for water.weather.gov)
• Comprehensive Evaluation Page for V2.8: RTMA, URMA, RTMA-RU, URMA time series at station locations, URMA QPE
