---|

---|
| 20 | # November 2015 - Leopold Haimberger (University of Vienna): |
---|
| 21 | # - extended with class Control |
---|
| 22 | # - removed functions mkdir_p, daterange, years_between, months_between |
---|
| 23 | # - added functions darain, dapoly, toparamId, init128, normalexit, |
---|
| 24 | # myerror, cleanup, install_args_and_control, |
---|
| 25 | # interpret_args_and_control, |
---|
| 26 | # - removed function __del__ in class EIFLexpart |
---|
| 27 | # - added the following functions in EIFlexpart: |
---|
| 28 | # - create_namelist |
---|
| 29 | # - process_output |
---|
| 30 | # - deacc_fluxes |
---|
| 31 | # - modified existing EIFlexpart - functions for the use in |
---|
| 32 | # flex_extract |
---|
| 33 | # - retrieve also longer term forecasts, not only analyses and |
---|
| 34 | # short term forecast data |
---|
| 35 | # - added conversion into GRIB2 |
---|
| 36 | # - added conversion into .fp format for faster execution of FLEXPART |
---|
| 37 | # (see https://www.flexpart.eu/wiki/FpCtbtoWo4FpFormat) |
---|
| 38 | # |
---|
| 39 | # February 2018 - Anne Philipp (University of Vienna): |
---|
| 40 | # - applied PEP8 style guide |
---|
| 41 | # - added documentation |
---|
| 42 | # - removed function getFlexpartTime in class ECFlexpart |
---|
| 43 | # - outsourced class ControlFile |
---|
| 44 | # - outsourced class MarsRetrieval |
---|
| 45 | # - changed class name from EIFlexpart to ECFlexpart |
---|
| 46 | # - applied minor code changes (style) |
---|
| 47 | # - removed "dead code" , e.g. retrieval of Q since it is not needed |
---|
| 48 | # - removed "times" parameter from retrieve-method since it is not used |

| 56 | # @Class Description: |
---|
| 57 | # FLEXPART needs grib files in a specifc format. All necessary data fields |
---|
| 58 | # for one time step are stored in a single file. The class represents an |
---|
| 59 | # instance with all the parameter and settings necessary for retrieving |
---|
| 60 | # MARS data and modifing them so they are fitting FLEXPART need. The class |
---|
| 61 | # is able to disaggregate the fluxes and convert grid types to the one needed |
---|
| 62 | # by FLEXPART, therefore using the FORTRAN program. |
