| 4 | The off-line processing concept included the main aspects: |
| 5 | |
| 6 | 1. Organisation of the routines that ingest and transform to .fp format into a single library or module file that could be used by both FLEXPART and the off-line pre-processing tool. Keep the developed routines with the FLEXPART source code distribution to ensure matching when compiling both the libraries and FLEXPART and to ensure maximum re-utilization of FLEXPART code. |
| 7 | 2. Add a switch in COMMAND file will allow it to read the .fp files directly or to use the usual on-the-fly processing of the GRIB incoming files. |
| 8 | 3. To be the start-up of a potential pre-processing system that could have plugged in additional met data (e.g. WRF). |

| 10 | The conceptual approach, which makes use as much as possible of original source code from FLEXPART, is as follows: |
