| 30 | The Control files are the steering part of the FLEXPART extraction |

| 33 | Some specific parameters like the start and end dates can be overwritten |
---|
| 34 | by the command line parameters, but in generel all parameters needed |
---|
| 35 | for a complete set of fields for FLEXPART can be set in the Control files. |
