| Info |

Please note that FLEXPART is not an ECMWF development. FLEXPART is not distributed with Metview, but it has to be installed separately. Please visit the FLEXPART website for installation instructions: https://www.flexpart.eu/. |
Compilation
Metview can only be compatible with FLEXPART if the size of the fortran record marker in the unformatted FLEXPART output is set to 4 bytes. Modern fortran compilers has a option to guarantee it. E.g. for gfortran:
| Code Block |
|---|
-frecord-marker=4 |
Code modifications
To make FLEXPART work with ECMWF data the following modifications has to be made in the source code:
Resolve type mismatch in err.f90 with newer gfortran compiler: see flextra ticket49
This involves the modification in err.f90 of line 106 and 111
and line 140 and 145 as well.
Make FLEXPART work for 137 model levels
In par_mod.f90 line 125 has to be modified:
FLEXPART paths
The location of the FLEXPART executable and that of some other files/directories have to be specified for Metview. These locations can be defined either through a set of Metview environment variables or via parameters in the FLEXPART Run icon (these latter take precedence). The table below summarises what actually is needed to set for Metview.
| Description | How to get it/them | Metview environment variable | Flexpart Run parameter |
|---|---|---|---|
| The FLEXPART executable | Need to be built from FLEXPART source | MV_FLEXPART_EXE_PATH | User Exe Path |
The directory containing the following files:
| These files are distributed in the FLEXPART source inside folder option | MV_FLEXPART_RESOURCES_PATH | User Resources Path |
| The directory containing the species | A set of species are distributed in the FLEXPART source inside folder option/SPECIES | MV_FLEXPART_SPECIES_PATH | User Species Path |
To see the actual values of the Metview environment variables run metview with the -h flag:
| Code Block |
|---|
metview -h |
This will dump all the Metview environment variable to the stdout.
