checkpoint47b_post |
| 7 |
|
Merging from release1_p9: |
| 8 |
|
o pkg/seaice |
| 9 |
|
- removed GOTO's and added taf directives |
| 10 |
|
- double precision constants to reduce the g77 (Linux) |
| 11 |
|
to F77 (SGI) differences reported in release1_p8 |
| 12 |
|
o tools/genmake |
| 13 |
|
- added SGI options |
| 14 |
|
o verification/testscript |
| 15 |
|
- updated to that of checkpoint47a_post |
| 16 |
|
o verification/global_ocean.90x40x15/input/eedata |
| 17 |
|
- modified for SGI f77 compatibility |
| 18 |
|
o verification/lab_sea |
| 19 |
|
- added description of sea-ice model |
| 20 |
|
- added missing matlab routines |
| 21 |
|
- added test of thermodynamics parallelization |
| 22 |
|
|
| 23 |
|
checkpoint47a_post |
| 24 |
|
o new pkg: aim_v23 |
| 25 |
|
= F. Molteni atmos.physics (SPEEDY, ver23) adapted to MITgcm. |
| 26 |
|
for now, keep the same surface forcing as before. |
| 27 |
|
- Part-Cell implemented into AIM; check that Heat & Water are conserved |
| 28 |
|
- aim.5l_cs: use new aim pkg (run 10yr & get better results than before) |
| 29 |
|
- aim.5l_LatLon & aim.5l_Equatorial_Channel are still using old aim pkg |
| 30 |
|
o add diagnostic of surface correction term in monitor output |
| 31 |
|
|
| 32 |
|
o bulk_force and therm_seaice |
| 33 |
|
- Two packages: bulk_force (Bulk forcing) |
| 34 |
|
and therm_seaice (thermodynamic_seaice) - adopted from LANL CICE.v2.0.2 |
| 35 |
|
- Earlier integration from Stephaine Dutkiewicz |
| 36 |
|
and Patrick Heimbach. |
| 37 |
|
- Two ifdef statements for compile time, |
| 38 |
|
ALLOW_THERM_SEAICE and ALLOW_BULK_FORCE |
| 39 |
|
|
| 40 |
|
checkpoint47 |
| 41 |
|
differentiable version of checkpoint46n_post |
| 42 |
|
o bug fix in quasihydrostaticterms |
| 43 |
|
o * "clean" adjoint code (in terms of extensive recomputations) |
| 44 |
|
can now be obtained for all GMREDI options (i.e. for |
| 45 |
|
- GM_VISBECK_VARIABLE_K |
| 46 |
|
- GM_NON_UNITY_DIAGONAL |
| 47 |
|
- GM_EXTRA_DIAGONAL |
| 48 |
|
- GM_BOLUS_ADVEC ) |
| 49 |
|
* However, wrong gradient check problem remains unsolved. |
| 50 |
|
* New CPP options have been introduced for different |
| 51 |
|
tapering schemes |
| 52 |
|
o external_fields_load now part of differentiation list |
| 53 |
|
o pressure needs multiple storing; |
| 54 |
|
would be nice to have store_pressure at beginning or |
| 55 |
|
end of forward_step, e.g. by having phiHyd global (5-dim.) |
| 56 |
|
(NB: pressure is needed for certain cases in find_rho, |
| 57 |
|
which is also invoked through convective_adjustment). |
| 58 |
|
o recomputations in find_rho for cases |
| 59 |
|
'JMD95'/'UNESCO' or 'MDJWF' are OK. |
| 60 |
|
o #define ATMOSPHERIC_LOADING should be differentiable |
| 61 |
|
o ini_forcing shifted to begining of initialise_varia |
| 62 |
|
o Incorporating QNVS line search routines into MITgcm |
| 63 |
|
(this is separate code, and therefore not under pkg) |
| 64 |
|
lsopt/, optim/ |
| 65 |
|
o Updated verification/carbon/ |
| 66 |
|
- #define GM_VISBECK_VARIABLE_K |
| 67 |
|
- GM_taper_scheme = 'ldd97' |
| 68 |
|
|
| 69 |
|
checkpoint46n_post |
| 70 |
|
Merging from release1_p8: |
| 71 |
|
o verification/natl_box: |
| 72 |
|
updating new external_fields_load routine |
| 73 |
|
o New package: pkg/seaice |
| 74 |
|
Sea ice model by D. Menemenlis (JPL) and Jinlun Zhang (Seattle). |
| 75 |
|
The sea-ice code is based on Hibler (1979-1980). |
| 76 |
|
Two sea-ice dynamic solvers, ADI and LSR, are included. |
| 77 |
|
In addition to computing prognostic sea-ice variables and diagnosing |
| 78 |
|
the forcing/external data fields that drive the ocean model, |
| 79 |
|
SEAICE_MODEL also sets theta to the freezing point under sea-ice. |
| 80 |
|
The implied surface heat flux is then stored in variable |
| 81 |
|
surfaceTendencyTice, which is needed by KPP package (kpp_calc.F and |
| 82 |
|
kpp_transport_t.F) to diagnose surface buoyancy fluxes and for the |
| 83 |
|
non-local transport term. Because this call precedes model |
| 84 |
|
thermodynamics, temperature under sea-ice may not be "exactly" at |
| 85 |
|
the freezing point by the time theta is dumped or time-averaged. |
| 86 |
|
N.B.: fairly large differences in accuracy occur across |
| 87 |
|
different platforms/compilers; comparison between |
| 88 |
|
g77 (Linux) and F77 (SGI Origin 2000/MIPSpro) |
| 89 |

|
o GAD: |
| 98 |
|
- generated new common blocks to account for call of |
| 99 |
|
same gad routines with differing traceridentities |
| 100 |
|
(needed to modify tracerIdentity indices in GAD.h) |
| 101 |
|
- generated separate common blocks for case useCubedSphereExchange |
| 102 |
|
(Department of Futurology) |
| 103 |
|
- parameter lists to gmredi_?transport: added tracerIdentity |
| 104 |
|
- added new key indices to tamc.h |
| 105 |
|
o external_fields_load: |
| 106 |
|
- added this routine to TAF list |
| 107 |
|
- needed to make some common blocks global and additional storing |
| 108 |
|
along the same lines as exf package (checkpoint_lev?_directives.h) |
| 109 |
|
o exf: |
| 110 |
|
updated external forcing package |
| 111 |
|
- bug fixes carried over from ecco-branch |
| 112 |
|
(missing OBCS_OPTIONS.h in two routines) |
| 113 |
|
- enable easy to use "no forcing". |
| 114 |
|
- added exf I/O for atmospheric loading |
| 115 |
|
- added exf I/O for runoff data |
| 116 |
|
- transfered scaling between exf <-> MITgcm to exf namelist |
| 117 |
|
o Adding new verification experiment global_with_exf. |
| 118 |
|
This verification experiment is almost identical to the |
| 119 |
|
global_ocean.90x40x15 experiment, except that it uses |
| 120 |
|
the exf (and cal) package instead of the |
| 121 |
|
external_fields_load routine (cf README file). |
| 122 |
|
|
| 123 |
|
checkpoint46m_post |
| 124 |
|
o modified testscript to return -- when there are no lines of "%MON" output |
| 125 |
|
o added new flag "quasiHydrostatic" for QH mode |
| 126 |
|
and new routine quasihydrostaticterms() |
| 127 |
o added 2*Omega*Cos(phi)*W to u equations (non-hydrostatic Coriolis term) |
o added 2*Omega*Cos(phi)*W to u equations (non-hydrostatic Coriolis term) |
| 128 |
New routine: mom_u_coriolis_nh() |
New routine: mom_u_coriolis_nh() |
| 129 |
o fixed sign of non-hydrostatic metric terms in u and v equations. |
o fixed sign of non-hydrostatic metric terms in u and v equations. |
