WPP Directory StructureUnder the main directory of WPPV3 reside five subdirectories:sorc: contains source codes for wrfpost, ndate, and copygb.scripts: contains sample running scriptsrun_wrfpost: run wrfpost and copygb.run_wrfpostandgempak: run wrfpost, copygb, and GEMPAK to plot variousfields.run_wrfpostandgrads: run wrfpost, copygb, and GrADS to plot variousfields.run_wrfpost_frames: run wrfpost and copygb on a single wrfout filecontaining multiple forecast times.run_wrfpost_gracet: run wrfpost and copygb on wrfout files with non-zerominutes/seconds.run_wrfpost_minute: run wrfpost and copygb for sub-hourly wrfout files.lib: contains source code subdirectories for the WRF Postprocessor libraries andis the directory where the WRF Postprocessor compiled libraries will reside.w3lib: Library for coding and decoding data in GRIB formatNote: The version of this library included in this package is Endianindependentand can be used on LINUX and IBM systems.iplib: General interpolation library (see lib/iplib/iplib.doc)splib: Spectral transform library (see lib/splib/splib.doc)wrfmpi_stubs: Contains some C and FORTRAN codes to genereate libmpi.alibrary. It supports MPI implementation for LINUX applications.parm: Contains the parameter files, which can be modified by the user to controlhow the post processing is performed.exec: Location of executables after compilation.Installing the WPP CodeWPP uses a build mechanism similar to that used by the WRF model. First issue theconfigure command, followed by the compile command.If the WRFV3 directory is not located at:../WRFV3the following environment variable must be set:setenv WRF_DIR /home/user/WRFV3If this is not set, the configure script will prompt you for it.Type configure, and provide the required info. For example:WRF-NMM V3: User’s Guide 7-3
./configureYou will be given a list of choices for your computer.Choices for IBM machines are as follows:1. AIX xlf compiler with xlc (serial)Choices for LINUX operating systems are as follows:1. LINUX i486 i586 i686, PGI compiler (serial)2. LINUX i486 i586 i686, Intel compiler (serial)3. LINUX i486 i586 i686, gfortran compiler (serial)Choose one of the configure options listed. Check the configure.wpp file created andedit for compile options/paths, if necessary.To compile WPP, enter the following command:./compile >& compile_wpp.log &This command should create four WRF Postprocessor libraries in lib/ (libmpi.a, libsp.a,libip.a, and libw3.a) and three WRF Postprocessor executables in exec/ (wrfpost.exe,ndate.exe, and copygb.exe).To remove all built files, as well as the configure.wpp, type:cleanThis action is recommended if a mistake is made during the installation process.WPP FunctionalitiesThe WRF Postprocessor V3,• is compatible with WRF v2.2 and higher.• can be used to post-process both WRF-ARW and WRF-NMM forecasts.• can ingest WRF history files (wrfout*) in two formats: netCDF and binary.The WRF Postprocessor is divided into two parts:1. Wrfpost• Interpolates the forecasts from the model’s native vertical coordinate to NWSstandard output levels (e.g., pressure, height) and computes mean sea levelpressure. If the requested parameter is on a model’s native level, then novertical interpolation is performed.• Computes diagnostic output quantities (e.g., convective available potentialenergy, helicity, radar reflectivity). A list of fields that can be generated bywrfpost is shown in Table 2.WRF-NMM V3: User’s Guide 7-4
