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
