  1. Planning Categories • Traditional LAPS Analysis • LAPS Analysis (Traditional / STMAS) • LAPS Forecast / WRF Updated 9/5/2010 OAR/ESRL/GSD/Forecast Applications Branch

  2. 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) OAR/ESRL/GSD/Forecast Applications Branch

  3. Traditional Analysis Plans - 2 OAR/ESRL/GSD/Forecast Applications Branch http://esrl.noaa.gov/gsd/fab • 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)

  4. 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?) OAR/ESRL/GSD/Forecast Applications Branch

  5. Analysis software plans - 2 OAR/ESRL/GSD/Forecast Applications Branch http://esrl.noaa.gov/gsd/fab • 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

  6. Analysis software plans - 3 OAR/ESRL/GSD/Forecast Applications Branch http://esrl.noaa.gov/gsd/fab • 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

  7. 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 OAR/ESRL/GSD/Forecast Applications Branch

  8. 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

  9. 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 OAR/ESRL/GSD/Forecast Applications Branch

  10. 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 OAR/ESRL/GSD/Forecast Applications Branch

  11. 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 OAR/ESRL/GSD/Forecast Applications Branch

  12. The End • Questions? • Answers? OAR/ESRL/GSD/Forecast Applications Branch
