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

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

Traditional Analysis Plans - 2 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) OAR/ESRL/GSD/Forecast Applications Branch

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

Analysis software plans - 2 AWIPS wish list (see – 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 OAR/ESRL/GSD/Forecast Applications Branch

Analysis software plans - 3 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 OAR/ESRL/GSD/Forecast Applications Branch

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 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

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 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

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

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?
