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 |
21 |
c changed: Christian Eckert eckert@mit.edu 11-Jan-2000 |
22 |
c - Restructured the code in order to create a package |
23 |
c for the MITgcmUV. |
24 |
c |
25 |
c Christian Eckert eckert@mit.edu 12-Feb-2000 |
26 |
c - Changed Routine names (package prefix: exf_) |
27 |
c |
28 |
c Patrick Heimbach, heimbach@mit.edu 04-May-2000 |
29 |
c - changed the handling of precip and sflux with respect |
30 |
c to CPP options ALLOW_BULKFORMULAE and ALLOW_ATM_TEMP |
31 |
c |
32 |
c changed: Ralf.Giering@FastOpt.de 25-Mai-20000 |
33 |
c - moved relaxation and climatology stuff to extra routines |
34 |
