WRF SI(The WRF Standard Initialization)

HWRF specific !!!

Dusan Jovic -- NOAA/NCEP/EMC

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"

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

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)

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
