---|
| 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 |

| 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"). |
