release1_p8 |
|
|
o verification/natl_box: |
|
|
updating new external_fields_load routine |
|
|
o New package: pkg/seaice |
|
|
Sea ice model by D. Menemenlis (JPL) and Jinlun Zhang (Seattle). |
|
|
The sea-ice code is based on Hibler (1979-1980). |
|
|
Two sea-ice dynamic solvers, ADI and LSR, are included. |
|
|
In addition to computing prognostic sea-ice variables and diagnosing |
|
|
the forcing/external data fields that drive the ocean model, |
|
|
SEAICE_MODEL also sets theta to the freezing point under sea-ice. |
|
|
The implied surface heat flux is then stored in variable |
|
|
surfaceTendencyTice, which is needed by KPP package (kpp_calc.F and |
|
|
kpp_transport_t.F) to diagnose surface buoyancy fluxes and for the |
|
|
non-local transport term. Because this call precedes model |
|
|
thermodynamics, temperature under sea-ice may not be "exactly" at |
|
|
the freezing point by the time theta is dumped or time-averaged. |
|
|
N.B.: fairly large differences in accuracy occur across |
|
|
different platforms/compilers; comparison between |
|
|
g77 (Linux) and F77 (SGI Origin 2000/MIPSpro) |
|

release1_p7 |
|
|
o GAD: |
|
|
- generated new common blocks to account for call of |
|
|
same gad routines with differing traceridentities |
|
|
(needed to modify tracerIdentity indices in GAD.h) |
|
|
- generated separate common blocks for case useCubedSphereExchange |
|
|
(Department of Futurology) |
|
|
- parameter lists to gmredi_?transport: added tracerIdentity |
|
|
- added new key indices to tamc.h |
|
|
o external_fields_load: |
|
|
- added this routine to TAF list |
|
|
- needed to make some common blocks global and additional storing |
|
|
along the same lines as exf package (checkpoint_lev?_directives.h) |
|
|
o exf: |
|
|
updated external forcing package |
|
|
- bug fixes carried over from ecco-branch |
|
|
(missing OBCS_OPTIONS.h in two routines) |
|
|
- enable easy to use "no forcing". |
|
|
- added exf I/O for atmospheric loading |
|
|
- added exf I/O for runoff data |
|
|
- transfered scaling between exf <-> MITgcm to exf namelist |
|
|
o Adding new verification experiment global_with_exf. |
|
|
This verification experiment is almost identical to the |
|
|
global_ocean.90x40x15 experiment, except that it uses |
|
|
the exf (and cal) package instead of the |
|
|
external_fields_load routine (cf README file). |
|
|
|
|
|
release1_p6 |
