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

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)
