c o This routine initialises the package that calculates external |
| 15 |
c forcing fields for a given timestep of the MITgcmUV. Parameters |
| 16 |
c for this package are set in "data.externalforcing". Some additional |
| 17 |
c precompiler switches have to be specified in "EXF_CPPOPTIONS.h". |

c - Restructured the code in order to create a package |
| 23 |
c for the MITgcmUV. |
| 24 |
c Christian Eckert eckert@mit.edu 12-Feb-2000 |
| 25 |
c - Changed Routine names (package prefix: exf_) |
| 26 |
c changed: Patrick Heimbach, heimbach@mit.edu 04-May-2000 |
| 27 |
c - changed the handling of precip and sflux with respect |
| 28 |
c to CPP options ALLOW_BULKFORMULAE and ALLOW_ATM_TEMP |
| 29 |
c changed: Ralf.Giering@FastOpt.de 25-Mai-20000 |
| 30 |
c - moved relaxation and climatology to extra routines |
| 31 |
c Patrick Heimbach, heimbach@mit.edu 04-May-2000 |
| 32 |
c - added obcs parameters |
| 33 |
c changed: Virginie Thierry, vthierry@ucsd.edu 04-June-2001 |
