C | SUBROUTINE OFFLINE_FIELDS_LOAD |
| 10 |
C | o Control reading of fields from external source. |
| 11 |
C *==========================================================* |
| 12 |
C | Offline External source field loading routine. |
| 13 |
C | This routine is called every time we want to |
| 14 |
C | load a a set of external fields. The routine decides |
| 15 |
C | which fields to load and then reads them in. |
| 16 |
C | This routine needs to be customised for particular |
| 17 |
C | experiments. |

C | Notes |
| 19 |
C | ===== |
| 20 |
C | Two-dimensional and three-dimensional I/O are handled in |
| 21 |
C | the following way under MITgcmUV. A master thread |
| 22 |
C | performs I/O using system calls. This threads reads data |
| 23 |
C | into a temporary buffer. At present the buffer is loaded |
| 24 |
C | with the entire model domain. This is probably OK for now |
| 25 |
C | Each thread then copies data from the buffer to the |
| 26 |
C | region of the proper array it is responsible for. |
| 27 |
C | ===== |
| 28 |
C | Conversion of flux fields are described in FFIELDS.h |
