---|
| 10 | # November 2015 - Leopold Haimberger (University of Vienna): |
---|
| 11 | # - extended with class Control |
---|
| 12 | # - removed functions mkdir_p, daterange, years_between, months_between |
---|
[ff99eae] | 13 | # - added functions darain, dapoly, to_param_id, init128, normal_exit, |
---|
| 14 | # my_error, clean_up, install_args_and_control, |
---|
[991df6a] | 15 | # interpret_args_and_control, |
---|
| 16 | # - removed function __del__ in class EIFLexpart |
---|
| 17 | # - added the following functions in EIFlexpart: |
---|
| 18 | # - create_namelist |
---|
| 19 | # - process_output |
---|
| 20 | # - deacc_fluxes |
---|
| 21 | # - modified existing EIFlexpart - functions for the use in |
---|
| 22 | # flex_extract |
---|
| 23 | # - retrieve also longer term forecasts, not only analyses and |
---|
| 24 | # short term forecast data |
---|
| 25 | # - added conversion into GRIB2 |
---|
| 26 | # - added conversion into .fp format for faster execution of FLEXPART |
---|
| 27 | # (see https://www.flexpart.eu/wiki/FpCtbtoWo4FpFormat) |
---|
| 28 | # |
---|
| 29 | # February 2018 - Anne Philipp (University of Vienna): |
---|
| 30 | # - applied PEP8 style guide |
---|
| 31 | # - added documentation |
---|
[ff99eae] | 32 | # - removed function getFlexpartTime in class EcFlexpart |
---|
[991df6a] | 33 | # - outsourced class ControlFile |
---|
| 34 | # - outsourced class MarsRetrieval |
---|
[ff99eae] | 35 | # - changed class name from EIFlexpart to EcFlexpart |
---|
[991df6a] | 36 | # - applied minor code changes (style) |
---|
| 37 | # - removed "dead code" , e.g. retrieval of Q since it is not needed |
---|
| 38 | # - removed "times" parameter from retrieve-method since it is not used |
---|
[27fe969] | 39 | # - seperated function "retrieve" into smaller functions (less code |
---|
| 40 | # duplication, easier testing) |

| 48 | # @Class Description: |
---|
| 49 | # FLEXPART needs grib files in a specifc format. All necessary data fields |
---|
| 50 | # for one time step are stored in a single file. The class represents an |
---|
| 51 | # instance with all the parameter and settings necessary for retrieving |
---|
| 52 | # MARS data and modifing them so they are fitting FLEXPART need. The class |
---|
| 53 | # is able to disaggregate the fluxes and convert grid types to the one needed |
---|
| 54 | # by FLEXPART, therefore using the FORTRAN program. |
---|

---|
| 887 | https://software.ecmwf.int/wiki/display/GRIB/index.py |
---|
| 888 | |
---|
| 889 | An index file will be created which depends on the combination |
---|
| 890 | of "date", "time" and "stepRange" values. This is used to iterate |
---|
| 891 | over all messages in each grib file which were passed through the |
---|
| 892 | parameter "inputfiles" to seperate specific parameters into fort.* |
---|
| 893 | files. Afterwards the FORTRAN program is called to convert |
---|
| 894 | the data fields all to the same grid and put them in one file |
---|
| 895 | per unique time step (combination of "date", "time" and |
---|
| 896 | "stepRange"). |
