8# @Change History:
9#
10#    November 2015 - Leopold Haimberger (University of Vienna):
11#        - using the WebAPI also for general MARS retrievals
12#        - job submission on ecgate and cca
13#        - job templates suitable for twice daily operational dissemination
14#        - dividing retrievals of longer periods into digestable chunks
15#        - retrieve also longer term forecasts, not only analyses and
16#          short term forecast data
17#        - conversion into GRIB2
18#        - conversion into .fp format for faster execution of FLEXPART
19#
20#    February 2018 - Anne Philipp (University of Vienna):
21#        - applied PEP8 style guide
22#        - added documentation
23#        - minor changes in programming style for consistence
[ff99eae]24#        - BUG: removed call of clean_up-Function after call of
[991df6a]25#               prepareFlexpart in main since it is already called in
26#               prepareFlexpart at the end!
27#        - created function main and moved the two function calls for
[ff99eae]28#          arguments and prepare_flexpart into it

35#
36# @Program Functionality:
37#    This program prepares the final version of the grib files which are
38#    then used by FLEXPART. It converts the bunch of grib files extracted
[ff99eae]39#    via get_mars_data by doing for example the necessary conversion to get
[991df6a]40#    consistent grids or the disaggregation of flux data. Finally, the
41#    program combines the data fields in files per available hour with the
42#    naming convention xxYYMMDDHH, where xx should be 2 arbitrary letters
43#    (mostly xx is chosen to be "EN").
44#
45# @Program Content:
46#    - main
[ff99eae]47#    - prepare_flexpart
