Hints for installing Flexpart v8.2

(should work for all Versions of Flexpart)

a step-by-step guidance for installing flexpart v8.2 at your local unix machine. Please consider to consult Flexpart v8.2 documentation

1. Download Grib-API und Jasper as described in the flexpart documentation

2. Install Jasper library

    mkdir /%HOME%/lib/
    cp %JASPER%.zip /%HOME%/lib
    cd %HOME%/lib
    unzip %JASPER%.zip
    cd %JASPER%
    ./configure --prefix=/%HOME%/lib/%JASPER%
    make
    make check
    make install
   

3. Install Grib-API library
   • mkdir /%HOME%/lib/src/
   • cp %GRIB%.tar.gz /%HOME%/lib/
   • cp %GRIB%.tar.gz /%HOME%/lib/src/
   • cd /%HOME%/lib/src/
   • tar -xvf %GRIB%.tar.gz
   • ./configure --prefix=/%HOME%/lib/%GRIB% --with-jasper=/%HOME%/lib/%JASPER%
   • make
   • make check
   • make install

4. Add the following lines to the bash.rc-file of your home directory:

• edit %HOME%/.bashrc (e.g. vi or emacs)
• export GRIB_API_BIN=“/%HOME/lib/%GRIB%/bin“
• export GRIB_API_LIB=“/%HOME/lib/%GRIB%/lib“
• export GRIB_API_INCLUDE=“/%HOME/lib/%GRIB%/include“
• export PATH=$GRIB_API_BIN:$PATH

5. Testing if Grib-API installation has been successful: read out Grib-file:
   • grib_ls %FILENAME%

6. Download Flexpart (%FLEXPART%.tar.gz) as described in the flexpart documentation

7. Unzip Flexpart-Archive, modify makefile und compile

• tar -xvf %FLEXPART%.tar.gz
• cp makefile.%(version)% makefile
• edit makefile (e.g. vi or emacs)
• Change lines to:
• INCPATH=/lib/%GRIB%/include
• LIBPATH1=/lib/%GRIB%/lib
• LIBPATH2=/lib/%JASPER%/lib

Adjust file includepar in the Flexpart-directory to your local computing capacities (if the values of the following parameters are choosen too high, compiling via make will fail)

• parameter(nxmax=721,nymax=361,nuvzmax=92,nwzmax=92,nzmax=92) (input: ECMWF windfields with resolution 0.5°)
• parameter(nxmax=361,nymax=181,nuvzmax=92,nwzmax=92,nzmax=92) (input: ECMWF windfields with resolution 1.0°)
• parameter(maxpart=22000000) (Change to: 1000000 (or 500000 / according to your computer specifications))
• parameter(maxspec=60) (Number of species. Change to 1 oder 2 (according to your computer specifications and your scientific problem)))
• make clean
• make
