  1. Dusan Jovic -- NOAA/NCEP/EMC WRF SI(The WRF Standard Initialization)HWRF specific !!!

  2. Main WRF SI tasks • Creates (localize) domains • Define location, projection, resolution • “static fields” preprocessor: interpolates terrain, landuse, ... • Decode input grib files (used for IC / BC)input grib files for IC can be different from those used for BC, or LSM • Horizontal interpolation from input grid to model grid (rot. lat-lon in NMM case) • Vertical interpolation (usually from P to hybrid-P coordinate)

  3. Required software • Fortran 90 compiler • C compiler • netCDF (libraries, include files and ncdump) • make • perl Required Input Files • Static data ( topography, landuse ...) ftp://aftp.fsl.noaa.gov/divisions/frd-laps/WRFSI/Geog_Data • Grib Data (GFS, Eta, ...)

  4. How to install and run WRF SI • untar the distribution file (will create HWRFV1 directory, SI is in NMMSI) • configure and compile SI • edit install.scr • /usr/bin/perl ./srcroot/install_wrfsi.pl \ --source_root="/emc2/wx20du/WRFEMC/HWRF/NMMSI/srcroot" \ --installroot="/emc2/wx20du/WRFEMC/HWRF/NMMSI/setup" \ --path_to_netcdf="/usrx/local/netcdf3.5" \ --geog_dataroot="/emc2/wx20py/wrfsigeog" \ --machine="ibm"

  5. set compiler options in srcroot/src/lib/w3lib.source_ei/Makefile andsrcroot/src/lib/w3lib.source_ei/clib.h • run install.scr • after compilation is done, in the$INSTALLROOT/bingridgen_model.exe grib_prep.exe hinterp.exe vinterp.exe siscan

  6. edit paths in$EXT_DATAROOT/static/grib_prep.nl &gpinput_defs SRCNAME = 'GFDL','ETA','GFS','AVN','AVNLSM','RUCH','NNRP', 'NNRPSFC','SST', SRCVTAB = 'GFDL','ETA','GFS','AVN','AVNLSM','RUCH','NNRPSFC','NNRPSFC','SST', SRCPATH = '/export/lnx280/wd20dj/HWRF/NMMSI/gribdata/GFDL', '/export/lnx280/wd20dj/HWRF/NMMSI/gribdata/ETA', '/export/lnx280/wd20dj/HWRF/NMMSI/gribdata/AVN', '/export/lnx280/wd20dj/HWRF/NMMSI/gribdata/AVN', '/export/lnx280/wd20dj/HWRF/NMMSI/gribdata/AVNLSM', '/rt0/rucdev/nrelwind/run/maps_fcst', '/path/to/nnrp/grib', '/path/to/nnrp/sfc/grib', '/public/data/grids/ncep/sst/grib', SRCCYCLE = 6,6,6,6,12,12,24, SRCDELAY = 3,4,4,3, 0, 0,36, /

  7. WRF SI main programs (overview) grib_prep gridgen_model hinterp vinterp

  8. Grib pre-processing (decoding) • decodes only desired grib messages(using Vtable) • reformats and writes 2d files in binary intermediate format suitable for hinterp • domain independent

  19. Horizontal interpolation (hinterp.exe) • uses wrfsi.nl for domain information • reads output files (binary “intermediate” format) from grib_prep • reads netCDF file from gridgen_model(static.wrfsi.rotlat) • horizontally interpolates 2d fields(interpolation method for “soil” (LSM) fields can be different from other fields)

  21. Vertical interpolation (vinterp.exe) • uses wrfsi.nl to determine number of vertical levels andvalues of sigma • reads output files from hinterp.exe • performs vertical interpolation • outputs netCDF files (one for each BC time step) to be read by real.exe
