| 5 | ``Flex_extract`` is an open-source software to retrieve meteorological fields from the European Centre for Medium-Range Weather Forecasts (ECMWF) Mars archive to serve as input files for the ``FLEXTRA``/``FLEXPART`` Atmospheric Transport Modelling system. |
---|
| 6 | ``Flex_extract`` was created explicitly for ``FLEXPART`` users who wants to use meteorological data from ECMWF to drive the ``FLEXPART`` model. |
---|
| 7 | The software retrieves the minimal number of parameters ``FLEXPART`` needs to work and provides the data in the explicity format ``FLEXPART`` understands. |
---|
| 8 | |
---|
| 9 | ``Flex_extract`` consists of 2 main parts: |
---|
| 10 | 1. a Python part, where the reading of parameter settings, retrieving data from MARS and preparing the data for ``FLEXPART`` is done and |
---|
| 11 | 2. a Fortran part, where the calculation of the vertical velocity is done and if necessary the conversion from spectral to regular latitude/longitude grids. |
---|
| 12 | |
---|
| 13 | Additionally, it has some Korn shell scripts which are used to set the environment and batch job features on ECMWF servers for the *gateway* and *remote* mode. See :doc:`Overview/app_modes` for information of application modes. |
---|
| 14 | |
---|
| 15 | A number of Shell scripts are wrapped around the software package for easy installation and fast job submission. |
---|
| 16 | |
---|
| 17 | The software depends on a number of third-party libraries which can be found in :ref:`ref-requirements`. |
---|
| 18 | |
---|
| 19 | Some details on the tasks and program worksteps are described in :doc:`Overview/prog_flow`. |
