WRF-VAR http://www.metoffice.gov.uk/science/creating/working_together/nwpsaf_public.html. The additional necessary environment variables needed are set (again using the C-shell), by commands looking something like > setenv RTTOV /usr/local/rttov87 (Note: make a linkage of $RTTOV/librttov.a to $RTTOV/src/librttov8.7.a) > setenv CRTM /usr/local/crtm (Note: make a linkage of $CRTM/libcrtm.a to $CRTM/src/libCRTM.a ) Note: Make sure the required libraries were all compiled using the same compiler that will be used to build WRF-Var, since the libraries produced by one compiler may not be compatible with code compiled with another. Assuming all required libraries are available, the WRF-Var source code can be downloaded from http://www.mmm.ucar.edu/wrf/users/wrfda/download/get_source.html. After the tar file is unzipped (gunzip WRFDAV3_1_1.TAR.gz) and untarred (untar WRFDAV3_1_1.TAR), the directory WRFDA should be created; this directory contains the WRF-Var source code. To configure WRF-Var, change to the WRFDA directory and type > ./configure wrfda A list of configuration options for your computer should appear. Each option combines a compiler type and a parallelism option; since the configuration script doesn’t check which compilers are actually available, be sure to only select among the options for compilers that are available on your system. The parallelism option allows for a singleprocessor (serial) compilation, shared-memory parallel (smpar) compilation, distributedmemory parallel (dmpar) compilation and distributed-memory with shared-memory parallel (sm+dm) compilation. For example, on a Macintosh computer, the above steps look like: > ./configure wrfda checking for perl5... no checking for perl... found /usr/bin/perl (perl) Will use NETCDF in dir: /users/noname/work/external/g95/netcdf-3.6.1 PHDF5 not set in environment. Will configure WRF for use without. $JASPERLIB or $JASPERINC not found in environment, configuring to build without grib2 I/O... ------------------------------------------------------------------------ Please select from among the following supported platforms. 1.

(0=no nesting, 1=basic, 2=preset moves, 3=vortex following) [default 0]: Configuration successful. To build the model type compile . …… After running the configure script and choosing a compilation option, a configure.wrf file will be created. Because of the variety of ways that a computer can be configured, if the WRF-Var build ultimately fails, there is a chance that minor modifications to the configure.wrf file may be needed. Note: WRF compiles with –r4 option while WRFDA compiles with –r8. For this reason, WRF and WRFDA cannot reside and be compiled under the same directory. Hint: It is helpful to start with something simple, such as the serial build. If it is successful, move on to build dmpar code. Remember to type ‘clean –a’ between each build. To compile the code, type > ./compile all_wrfvar >&! compile.out Successful compilation of ‘all_wrfvar” will produce 31 executables in the var/build directory which are linked in var/da directory, as well as obsproc.exe in var/obsproc/src directory. You can list these executables by issuing the command (from WRFDA directory) > ls -l var/build/*exe var/obsproc/src/obsproc.exe -rwxr-xr-x 1 noname users 641048 Mar 23 09:28 var/build/da_advance_time.exe -rwxr-xr-x 1 noname users 954016 Mar 23 09:29 var/build/da_bias_airmass.exe -rwxr-xr-x 1 noname users 721140 Mar 23 09:29 var/build/da_bias_scan.exe -rwxr-xr-x 1 noname users 686652 Mar 23 09:29 var/build/da_bias_sele.exe -rwxr-xr-x 1 noname users 700772 Mar 23 09:29 var/build/da_bias_verif.exe -rwxr-xr-x 1 noname users 895300 Mar 23 09:29 var/build/da_rad_diags.exe -rwxr-xr-x 1 noname users 742660 Mar 23 09:29 var/build/da_tune_obs_desroziers.exe -rwxr-xr-x 1 noname users 942948 Mar 23 09:29 var/build/da_tune_obs_hollingsworth1.exe -rwxr-xr-x 1 noname users 913904 Mar 23 09:29 var/build/da_tune_obs_hollingsworth2.exe -rwxr-xr-x 1 noname users 943000 Mar 23 09:28 var/build/da_update_bc.exe -rwxr-xr-x 1 noname users 1125892 Mar 23 09:29 var/build/da_verif_anal.exe -rwxr-xr-x 1 noname users 705200 Mar 23 09:29 var/build/da_verif_obs.exe -rwxr-xr-x 1 noname users 46602708 Mar 23 09:28 var/build/da_wrfvar.exe -rwxr-xr-x 1 noname users 1938628 Mar 23 09:29 var/build/gen_be_cov2d.exe -rwxr-xr-x 1 noname users 1938628 Mar 23 09:29 var/build/gen_be_cov3d.exe -rwxr-xr-x 1 noname users 1930436 Mar 23 09:29 var/build/gen_be_diags.exe -rwxr-xr-x 1 noname users 1942724 Mar 23 09:29 var/build/gen_be_diags_read.exe -rwxr-xr-x 1 noname users 1941268 Mar 23 09:29 var/build/gen_be_ensmean.exe -rwxr-xr-x 1 noname users 1955192 Mar 23 09:29 var/build/gen_be_ensrf.exe -rwxr-xr-x 1 noname users 1979588 Mar 23 09:28 var/build/gen_be_ep1.exe -rwxr-xr-x 1 noname users 1961948 Mar 23 09:28 var/build/gen_be_ep2.exe -rwxr-xr-x 1 noname users 1945360 Mar 23 09:29 var/build/gen_be_etkf.exe -rwxr-xr-x 1 noname users 1990936 Mar 23 09:28 var/build/gen_be_stage0_wrf.exe -rwxr-xr-x 1 noname users 1955012 Mar 23 09:28 var/build/gen_be_stage1.exe -rwxr-xr-x 1 noname users 1967296 Mar 23 09:28 var/build/gen_be_stage1_1dvar.exe -rwxr-xr-x 1 noname users 1950916 Mar 23 09:28 var/build/gen_be_stage2.exe -rwxr-xr-x 1 noname users 2160796 Mar 23 09:29 var/build/gen_be_stage2_1dvar.exe -rwxr-xr-x 1 noname users 1942724 Mar 23 09:29 var/build/gen_be_stage2a.exe -rwxr-xr-x 1 noname users 1950916 Mar 23 09:29 var/build/gen_be_stage3.exe -rwxr-xr-x 1 noname users 1938628 Mar 23 09:29 var/build/gen_be_stage4_global.exe WRF-ARW V3: User’s Guide 6-5
