[d69b677] | 6 | # Functionality provided: Prepare input 3D-wind fields in hybrid coordinates + surface fields for FLEXPART runs |
---|
| 7 | # |
---|
| 8 | # Creation: October 2014 - Anne Fouilloux - University of Oslo |
---|
[64cf353] | 9 | # Extension November 2015 - Leopold Haimberger - University of Vienna for: |
---|
[d69b677] | 10 | # - using the WebAPI also for general MARS retrievals |
---|
| 11 | # - job submission on ecgate and cca |
---|
| 12 | # - job templates suitable for twice daily operational dissemination |
---|
| 13 | # - dividing retrievals of longer periods into digestable chunks |
---|
| 14 | # - retrieve also longer term forecasts, not only analyses and short term forecast data |
---|
| 15 | # - conversion into GRIB2 |
---|
| 16 | # - conversion into .fp format for faster execution of FLEXPART |
---|

| 18 | # Requirements: |
---|
[d69b677] | 19 | # in addition to a standard python 2.6 or 2.7 installation the following packages need to be installed |
---|
[64cf353] | 20 | # ECMWF WebMARS, gribAPI with python enabled, emoslib, ecaccess web toolkit, |
---|
| 21 | # all available from https://software.ecmwf.int/ |
---|
[d69b677] | 22 | # dateutils |
---|
| 23 | # matplotlib (optional, for debugging) |
