put in proper trac markup

FLEPXART-NorESM/CAM (V1) is based on FLEXPART V9. The code is very similar to the original FLEXPARTV9.

  • Compared to the standard FLEXPART V9 this NorESm/CAM version does not allow nesting and it is tailored to run using the grid resolution of NorESM in the CMIP5 configuration (1.89°×2.5°) and 26 vertical levels.
  • In COMMAND there is an added flag to set the method to calculate the vertical velocity (see GMD manuscript in preparation, see bottom of the page) and
  • in PATHNAMES there is an additional path to a file defining the grid structure of the meteorological input data.

The download and installation test procedure (you need git on your local system, available as standard package of all Linux distros (Git homepage: ):

  1. Create a base directory e.g.
    mkdir ~/repos
  1. Get the code using Git, type the command:
    git clone -b flexpart-noresm This will create a local flexpart directory containing the sub-directories
    • src (with sources),
    • tests and
    • options.
  1. Get the meteorological data and two extra .dat files needed by FLEXPART (~650 Mb): Download the file flexpartnoresm.dat.tar from
  1. Decompress the data using the command:
    tar -xf flexpartnoresm.dat.tar
    the archive contains the driving meteorological data for tests (in sub-directory meteogrid) and two essential input .dat files that FLEXPART needs in the options directory
  1. Be sure to move the two input .dat files mentioned in 4. to the options directory e.g. use command: mv *.dat options '
  2. Once the structure is in place one has to create the executable.
    1. make sure the NetCDF libraries are available (Standard package for Linux, see also
    2. modify the makefile where needed to link to your local NetCDF library
    3. make the executable: make -f makefile_noresm_gfortran

  1. Finally test that the installation works
    1. go to the tests directory
    2. execute the file ./create_tests
      It will create 3 basic test cases in the directory ~/repos/flexpart/tests_tmp
      execute the file ./create_and_run
      It will create the tests and run automatically
