= FLEXPART for input data from climate models =


FLEXPART versions have been developed for using meteorological input data produced by climate models. At present, information is available on 

  - [wiki:FpClimateNorESM FLEXPART-NorESM/CAM ]

The download and installation test procedure:

1) Create a base directory e.g.
  mkdir ~/repos

2) Get the code using Git, type the command: 
git clone https://www.flexpart.eu/gitmob/flexpart -b flexpart-noresm

Make be sure Git is installed in your system  https://git-scm.com/downloads. This will create a local “flexpart” directory containing the sub-directories “src” (with sources), “tests” and “options”

3) Get the meteorological data and two extra “.dat” files needed by FLEXPART  (~650 Mb)
Downloading the file “flexpartnoresm.dat.tar”  from:
 https://www.flexpart.eu/downloads/53

The archive contains the meteorological data (meteogrid) and two additional “.dat” files that FLEXPART needs inside the directory “options”  

4) 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

5) be sure to move the two input “.dat files”  mentioned in (4) to the options directory e.g. use command:
     mv *.dat options
 
6)  Once the structure is in place one has to create the executable.
 a) make sure the NetCDF libraries are available (http://www.unidata.ucar.edu/software/netcdf/)
 b) modify the makefile where needed to link to your local NetCDF library 
 c) make the executable:  make -f makefile_noresm_gfortran
 
7) Finally test that the installation works
a) go to the “tests” directory 
b1) execute the file  ./create_tests
It will create 3 basic test cases in the directory ~/repos/flexpart/tests_tmp
b2) or execute the file  /create_and_run
It  will create the tests and run automatically
