rb1674ed rf20342a 3 3 ======== 4 4 5 ``Flex_extract`` is an open-source software to retrieve meteorological fields from the European Centre for Medium-Range Weather Forecasts (ECMWF) M ars archive to serve as input files for the ``FLEXTRA``/``FLEXPART`` Atmospheric Transport Modelling system.6 ``Flex_extract`` was created explicitly for ``FLEXPART`` users who want sto use meteorological data from ECMWF to drive the ``FLEXPART`` model.7 The software retrieves the minim al number of parameters ``FLEXPART`` needs to work and provides the data in the explicity format ``FLEXPART`` understands.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 want to use meteorological data from ECMWF to drive the ``FLEXPART`` model. 7 The software retrieves the minimum set of parameters needed by ``FLEXPART`` to work, and provides the data in the specific format required by ``FLEXPART``. 8 8 9 ``Flex_extract`` consists of 2main parts:10 1. a Python part , where the reading of parameter settings, retrieving data from MARS and preparing the data for ``FLEXPART`` is doneand11 2. a Fortran part , where the calculation of the vertical velocity is done and if necessary the conversion from spectralto regular latitude/longitude grids.9 ``Flex_extract`` consists of two main parts: 10 1. a Python part which reads the parameter settings, retrieves the data from MARS, and prepares them for ``FLEXPART``, and 11 2. a Fortran part which calculates the vertical velocity and, if necessary, converts variables from the spectral representation to regular latitude/longitude grids. 12 12 13 Additionally, it has some Korn shell scripts which are usedto 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.13 In addition, there are some Korn shell scripts 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 14 15 15 A number of Shell scripts are wrapped around the software package for easy installation and fast job submission. 16 16 17 The software depends on a number of third-party libraries which can be found in :ref:`ref-requirements`.17 The software depends on some third-party libraries as listed in :ref:`ref-requirements`. 18 18 19 Some details on the tasks and program worksteps are described in :doc:`Overview/prog_flow`.19 Details of the tasks and program work steps are described in :doc:`Overview/prog_flow`. 20 20 21 21
