traditional analysis plans 1
Traditional Analysis Plans - 1
  • Gauge Radar Blended Analysis(Steve)
    • Requested by FMI, Ed Tollerud
    • Domain wide radar/gauge bias option
    • Spatially varying bias option
    • Compare to NCEP (CPC and/or Stage IV), Steve Mullen techniques
  • Split off Cloud type from Precip Type?(Steve, Dan)
    • or calculate stability in the humidity analysis
  • Add GOES 13 capability in LVD code Adrianne, Dan, Steve
    • Add comments about present GOES13 workaround in LVD and humidity namelists (Steve, Dan)

  • AWIPS / NWS GPS support(Dan, Kirk)
    • NOAAPORT netCDF format (no longer available)
    • now contained in MADIS mesonet surface data
    • Read MADIS mesonet via Yuanfu’s (src/lib) routine and switch the ‘src/humid’ code to point to this more generic routine
  • GLAPS
    • add GPS and polar orbiting satellites in comparison run? (Kirk/Seth)
    • improve humidity efficiency? (Dan)
      • Runs in 10 minutes for GLAPS
  • Switch build scripts from ‘toro’ to ‘pinky’ (Steve,Scott)
analysis software plans 1
Analysis software plans - 1
  • CRTM development
    • Install library on ‘pinky’ (/usr/nfs/lapb/builds or /usr/local)
  • Sigma-P code in LGA & STMAS (Steve, Yuanfu)
  • Hook up to sub-kilometer terrain data (Steve, Paula, Adrianne)
    • Read topo-grabber tile output with ‘gridgen_model’ (GGM) software
    • GGM currently used in LAPS/STMAS localization to reproject USGS ‘topo_30s’ tiles and other static data onto domain map projection
    • Writes out static file in netCDF format
    • Combine 1 sec terrain, land use with other static data (e.g. albedo, soil type, green fraction)
    • GGM software does post processing (land/water fraction, sub-grid roughness, etc.)
  • GPU tests on Mac Machines with NVIDIA cards (or Titan?)

  • AWIPS wish list (see http://laps.noaa.gov/LAPB/AWIPS_WFO_page.htm)
    • Example is NST parameter (Ed Szoke, Steve)
  • Improve LGA efficiency (Steve, Paula)
    • Do calculations/subroutine calls with 2D arrays (e.g. wind rotation)
    • Read GRIB NAV data only once
    • Read GRIB NAV data without reading the whole file
    • Eliminate redundant lgb file processing
    • Try bilinear interpolation for 3D fields projected to the sfc

  • Incorporate cloud/radar related forward models that mimics what LAPS does into STMAS, then GSI (CRTM and other techniques) (Steve, Yuanfu, Paul, Dan, Tomoko)
    • Radar reflectivity / microphysics
    • METAR cloud observations
    • Pilot reports of cloud layers (and maybe icing)
    • Constraint between clouds/reflectivity and omega for hot-start (weak or strong depending on model initialization time tendencies)
    • Visible satellite (via CRTM)
    • SFMR (Step Frequency Microwave Radiometer)
    • Airborne radar (velocity and reflectivity)
  • Also moisture related forward models such as GPS total delay
analysis software plans 4
Analysis software plans - 4
  • NNEW access
    • start with model first guess (helpful when using HRRR as background for small rapid update domains)
    • also consider satellite (present weak link?)
    • recent email thread (Dan, Paul, Kirk)
  • Parallelize slower code sections (MPI, SMS, GPUs)
    • LAPS wind analysis (maybe temp/sfc) (Steve, Jacques)
    • Model first guess interpolation (LGA)?
    • STMAS minimization routine
  • Clean up Linux compiler Warnings in library C code (Linda,Dan)?
  • XML for scheduling on JET? (Steve)
  • Manage improved Web Forum (Steve)
  • Improved verification

Analysis software plans - 5
  • Quality control of surface obs (temporal checks)
    • Read MADIS statistics from separate files for more detailed info?
      • Allows improvement over thresholds used for statistical spatial consistency check
    • Use internal LAPS history statistics to do MADIS-like QC checks (Steve)
      • Useful at CWB as they are independent of MADIS
      • We could implement our own “stuck-sensor” check
  • New radar interface
    • Archive-II to Volume netCDF files
      • via standard UNIDATA Java interface
    • Update existing remap code to read volume files (vs. tilt files)

OAR/ESRL/GSD/Forecast Applications Branch

laps wrf software plans 1
LAPS / WRF software plans - 1
  • Improve initialization / hot-start (match between analysis and zero hour forecast)
    • Discrepancies noticed in Windsor and HMT runs
    • WRF now installed on FAB machine for testing / debugging
  • Synthetic Forecast Satellite Images
    • a package that can be run in real-time
    • helps visualize and compare model forecasts
    • CRTM (leading contender at present)
    • Isidora’s work with Louis Grasso
    • Bob Rabin OLR

laps wrf software plans 2
LAPS / WRF software Plans - 2
  • Reliability of forecast products
    • ITS can monitor end-to-end of run via web product continuity
    • decide on domains to be monitored (currently ROC 5km/DWR/HMT)
  • Increase grid resolution of ROC operational domain to ~3km?
    • in support of nowcasting and forecast comparisons
    • to address related Doppler radial velocity data timing constraint
      • improve radar “thinning”
      • 1km 15-min ROC subset (400x500km) running on WJET using MPI
      • turn radial velocity off for now?
    • Balance package parallelization may also be needed for larger 1km 15-min domain

general thoughts
General Thoughts
  • Priorities may change as new requests & ideas continually arise
  • Ideas and volunteers are both beneficial
  • Continue to get feedback from our users – as well as plan for the upcoming workshop
    • New forum almost ready
    • Advertise workshop to NWS forecasters?
      • Regional AWIPS focal points
      • awipsinfo email list
      • Nearby WFOs
