17 | # November 2015 - Leopold Haimberger (University of Vienna): |
---|
18 | # - using the WebAPI also for general MARS retrievals |
---|
19 | # - job submission on ecgate and cca |
---|
20 | # - job templates suitable for twice daily operational dissemination |
---|
21 | # - dividing retrievals of longer periods into digestable chunks |
---|
22 | # - retrieve also longer term forecasts, not only analyses and |
---|
23 | # short term forecast data |
---|
24 | # - conversion into GRIB2 |
---|
25 | # - conversion into .fp format for faster execution of FLEXPART |
---|
26 | # |
---|
27 | # February 2018 - Anne Philipp (University of Vienna): |
---|
28 | # - applied PEP8 style guide |
---|
29 | # - added documentation |
---|
30 | # - minor changes in programming style for consistence |
---|
31 | # - BUG: removed call of cleanup-Function after call of |
---|
32 | # prepareFlexpart in main since it is already called in |
---|
33 | # prepareFlexpart at the end! |
---|
34 | # - created function main and moved the two function calls for |
---|
35 | # arguments and prepareFLEXPART into it |

43 | # @Program Functionality: |
---|
44 | # This program prepares the final version of the grib files which are |
---|
45 | # then used by FLEXPART. It converts the bunch of grib files extracted |
---|
46 | # via getMARSdata by doing for example the necessary conversion to get |
---|
47 | # consistent grids or the disaggregation of flux data. Finally, the |
---|
48 | # program combines the data fields in files per available hour with the |
---|
49 | # naming convention xxYYMMDDHH, where xx should be 2 arbitrary letters |
---|
50 | # (mostly xx is chosen to be "EN"). |
---|
51 | # |
---|
