| 9 |
|
- modify fluxes but do not change theta directly; |
| 10 |
|
- light cleaning of bulk_force pkg (still needed with thsice). |
| 11 |
|

| 12 |
|
+ output_thsice.txt to test thsice & bulk_force pkgs. |

| 30 |
|
- keep the old version of FREEZE for backward compatibility; |
| 31 |
|
global_ocean.90x40x15 left unchanged using useOldFreezing=.TRUE. |
| 32 |

| 59 |
|
|
| 60 |

| 76 |
|
|
| 77 |
|
checkpoint51q_post |
| 78 |
|
o cd_code: |
| 79 |
|
- moved cd_scheme.F -> cd_code_scheme.F |

checkpoint51p_post |
| 94 |
|
o create initial cd_code package |
| 95 |
|
- WARNING: the initialization of fields within packages |
| 96 |
|
is broken because INI_FIELDS (where READ_CHECKPOINT is |
| 97 |
|
called) is called *before* PACKAGES_INIT_VARIABLES. |
| 98 |
|
This seems to be backwards since |
| 99 |
|
1) its important to initially zero the entire field including |
| 100 |
|
the "halo" region |
| 101 |
|
2) zeroing needs to be done *before* reading pickup info |
| 102 |
|
and the pickup call might or might not happen in any |
| 103 |
|
particular run |
| 104 |
|
- this needs an overhaul for R2 |

| 119 |
|
change rho -> rho-rhoConst |
| 120 |
|
- replace call find_rho to find_rhonum |

o removed lots of single quotes from comments |
| 344 |
|
|
| 345 |
|
checkpoint50e_post |
| 346 |
|
o make KPP work with PTRACERS |
| 347 |
|
- fix gad_calc_rhs to call new routine kpp_transport_ptr, which is |
| 348 |
|
nearly a copy of kpp_transport_s |
| 349 |
|
- there is no analogue to SurfaceTendencyS, so I have to use |
| 350 |
|
gPtr(of the surface layer) instead |
| 351 |
|
o add a new platform SunFire+mpi (SunFire 15000) to genmake |
| 352 |
|
checkpoint50e_pre |
| 353 |
|
|
| 354 |
|
checkpoint50d_post |
| 355 |
|
o change kpp output from multiple-record state files to single-record state |
| 356 |
|
files analogous to write_state.F |
| 357 |
|
o reduce the output frequency of cg3d-related stuff to the monitor frequency, |
| 358 |
|
analogous to the cg2d-related output. |
| 359 |
|
o fix small problem with in ptracers_write_checkpoint.F: len(suff)=512, |
| 360 |
|
so that writing to internal file fn (with length 512) fails. |
| 361 |
|
checkpoint50d_pre |
| 362 |
|
|
| 363 |
|
checkpoint50c_post |
| 364 |
|
o fix problem in ini_procs.F when using MPI (was there since checkpoint48f) |
| 365 |
|
o add monitor diagnostic of vorticity (mon_vort3.F) and potential energy. |
| 366 |
|
o add time-average diagnostic of U*V and vertical diffusive flux for theta. |
| 367 |
|
o bug fixed in convective adjustment diagnostic (multi-tile set-up). |
| 368 |
|
o 4th Order Adv scheme: return to previous (c40pre7) masking near boundaries. |
| 369 |
|
|
| 370 |
|
checkpoint50c_pre |
| 371 |
|
Merging from release1_p13: |
| 372 |
|
o bug fix for pkg/seaice dynamic solver |
| 373 |
|
o Added SEAICE_initialHEFF to pkg/seaice |
| 374 |
|
|
| 375 |
|
checkpoint50b_post |
| 376 |
|
o store u*,v* in gU,V instead of in guNm1,gvNm1 |
| 377 |
|
o in order to put the momForcing out of the Adams-Bashforth: |
| 378 |
|
move forcing & CD-scheme calls from mom_fluxform & mom_vecinv |
| 379 |
|
to timestep.F |
| 380 |
|
o new flag "useCDscheme" (default=F); replace guCD,gvCD by local arrays |
| 381 |
|
o re-generate output for highly sensitive test-exp: |
| 382 |
|
global_ocean_pressure, ideal_2D_oce, lab_sea, natl_box |
| 383 |
|
|
| 384 |
|
checkpoint50b_pre |
| 385 |
|
o restore the use of momAdvection & useCoriolis flags (mom_vecinv) |
| 386 |
|
o corrected CPP option mismatch in exf_Bulk... functions for case |
| 387 |
|
#define ALLOW_ATM_WIND && #undef ALLOW_ATM_TEMP |
| 388 |
|
|
| 389 |
|
checkpoint50a_post |
| 390 |
|
o Bug fix for merging between c50 and KPP. |
| 391 |
|
ikey was passed from thermodynamics to kpp_calc via |
| 392 |
|
common block rather than being recomputed in kpp_calc, |
| 393 |
|
in contradiction with new key itdkey. |
| 394 |
|
New key ikppkey created, and tamc.h headers updated. |
| 395 |
|
|
| 396 |
|
checkpoint50 |
| 397 |
|
- 2nd step of merge with ecco-branch: |
| 398 |
|
merge changes in ecco-branch back into main trunk |
| 399 |
|
- bug fix in find_alpha |
| 400 |
|
- more storing in gmredi_calc_tensor.F, kpp_routines.F |
| 401 |
|
- avoid iterative loop in ini_pressure for ALLOW_AUTODIFF_TAMC |
| 402 |
|
- merged some sliced AD support routines |
| 403 |
|
|
| 404 |
|
checkpoint49 |
| 405 |
|
merged from ecco-branch: |
| 406 |
|
o exf: |
| 407 |
|
- Enable initialisation of forcing fields to constant |
| 408 |
|
(runtime) values. |
| 409 |
|
- in exf_getffields.F |
| 410 |
|
Reduce i-/j-loop to interior domain, discarding overlaps. |
| 411 |
|
That also fixes wrong TAF-key computations for key_1, key_2 |
| 412 |
|
with bulf formulae. |
| 413 |
|
- exf_init.F modify #ifdef for exf_init_evap |
| 414 |
|
- exf_getffieldrec.F, ctrl_getrec.F |
| 415 |
|
The following INT-usages are not safe: |
| 416 |
|
fldsecs = int(fldsecs/fldperiod)*fldperiod |
| 417 |
|
fldcount = int(fldsecs/fldperiod) + 1 |
| 418 |
|
and were modified. |
| 419 |
|
o autodiff: checkpoint_lev... |
| 420 |
|
- updated storing for bulk formulae (some arrays were missing) |
| 421 |
|
- added state for seaice package |
| 422 |
|
- synchronized with main branch |
| 423 |
|
o DIVA: |
| 424 |
|
Modif.s in |
| 425 |
|
- the_main_loop.F |
| 426 |
|
- the_model_main.F |
| 427 |
|
and added cost_final_restore.F cost_final_store.F |
| 428 |
|
o With these changes, it is possible to fully separate |
| 429 |
|
the first forward run to compute the cost function (mdthe_main_loop) |
| 430 |
|
and adjoint runs over individual DIVA intervals (adthe_main_loop) |
| 431 |
|
into separate model executions. |
| 432 |
|
This enables better tuning of DIVA to given queue sizes. |
| 433 |
|
o Loss of cost function value in consecutive DIVA runs is |
| 434 |
|
fixed by storing to 'costfinal' file. |
| 435 |
|
o Appropriate call of ctrl_unpack/_pack,grdchk_main at |
| 436 |
|
beginning/end of adjoint integration is accounted for. |
| 437 |
|
The current changes apply to TAF-1.4.26. |
| 438 |
|
TAF has one remaining bug, requiring one manual change |
| 439 |
|
(see MITgcm manual). |
| 440 |
|
o cal: synchronized between MAIN and ecco-branch |
| 441 |
|
|
| 442 |
|
checkpoint48i_post |
| 443 |
|
o Changes to restore differentiability of code w.r.t. previous tag |
| 444 |
|
(mostly adding new routines to make list and replacing |
| 445 |
|
pressure by totPhiHyd). |
| 446 |
|
o Updated and merged grdchk package |
| 447 |
|
- has both ADM and TLM checks |
| 448 |
|
- works for single- and multi-proc. |
| 449 |
|
- output cleaned |
| 450 |
|
- worked successfully for parallel DIVA |
| 451 |
|
o genmake: |
| 452 |
|
- Adding -platform=SP4 |
| 453 |
|
- Modif. for DEC Alpha (many don't have makedepend; use mkdep instead). |
| 454 |
|
o Modif. for DIVA: |
| 455 |
|
ctrl_unpack should not be called in intermediate DIVA interval. |
| 456 |
|
(similar thing would apply for active files such as |
| 457 |
|
tbar, sbar, psbar, which should not be reinitialised; |
| 458 |
|
only relevant for ecco-branch) |
| 459 |
|
|
| 460 |
|
checkpoint48h_post |
| 461 |
|
o improve "ini_p_ground" when using finite difference form for calc_phi_hyd |
| 462 |
|
o Added net flux to downward flux conversion to pkg/exf/exf_getffields.F |
| 463 |
|
o Added SEAICE_initialHEFF to pkg/seaice |
| 464 |
|
o ecco_the_model_main.F: SEAICE_WRITE_PICKUP must precede WRITE_CHECKPOINT |
| 465 |
|
|
| 466 |
|
checkpoint48g_post |
| 467 |
|
--- EOS: |
| 468 |
|
o compute locally the pressure for use in EOS: UNESCO, JMD95P, MDJWF |
| 469 |
|
store total Potential in totPhyHyd for diagnostics & EOS. |
| 470 |
|
o fix restart and overlap Pb when using Z-coord and EOS funct. of P |
| 471 |
|
--- Pressure/geopotential gradient: |
| 472 |
|
o use Ro_surf & R_low instead of hFac in cal_phi_hyd: |
| 473 |
|
o NLFS + p-coord.: eta*Alpha' is not longer lagging 1.time-step behind |
| 474 |
|
( changes results of global_ocean_pressure ) |
| 475 |
|
o NLFS + z-coord.: add eta*Rho' contribution. |
| 476 |
|
o accurate phiHyd when using interface-W at the middle between 2 centers |
| 477 |
|
( changes results of ideal_2D_oce ) |
| 478 |
|
o includes r* 2nd term in potential gradient. |
| 479 |
|
|
| 480 |
|
checkpoint48f_post |
| 481 |
|
Merging from release1_p12: |
| 482 |
|

| 487 |
|
o Added pkg/sbo for computing IERS Special Bureau for the Oceans |
| 488 |
|
(SBO) core products, including oceanic mass, center-of-mass, |
| 489 |
|
angular, and bottom pressure (see pkg/sbo/README.sbo). |
| 490 |
|
o Lower bound for viscosity/diffusivity in pkg/kpp/kpp_routines.F |
| 491 |
|
to avoid negative values in shallow regions. |
| 492 |
|
- updated verification/natl_box/results/output.txt |
| 493 |
|
- updated verification/lab_sea/results/output.txt |
| 494 |
|
o MPI gather, scatter: eesupp/src/gather_2d.F and scatter_2d.F |
| 495 |
|
o Added useSingleCpuIO option (see PARAMS.h). |
| 496 |
|
o Updated useSingleCpuIO option in mdsio_writefield.F to |
| 497 |
|
work with multi-field files, e.g., for single-file pickup. |
| 498 |
|
o pkg/seaice: |
| 499 |
|
- bug fix in growth.F: QNET for no shortwave case |
| 500 |
|
- added HeffFile for specifying initial sea-ice thickness |
| 501 |
|
- changed SEAICE_EXTERNAL_FLUXES wind stress implementation |
| 502 |
|
o Added missing /* */ to CPP comments in pkg/seaice, pkg/exf, |
| 503 |
|
kpp_transport_t.F, forward_step.F, and the_main_loop.F |
| 504 |
|
o pkg/seaice: |
| 505 |
|
- adjoint-friendly modifications |
| 506 |
|
- added a SEAICE_WRITE_PICKUP at end of the_model_main.F |
| 507 |
|
|
| 508 |
|
checkpoint48e_post |
| 509 |
|
o New S/R for diagnostic of bottom pressure (phi0surf was missing in c48d_post) |
| 510 |
|
o dynamics: change definition of computational domain & adapt mom_fluxform |
| 511 |
|
accordingly ; when viscA4=0, allows to run the dynamics with Olx=Oly=2. |
| 512 |
|
o following exp works with Olx=Oly=2 (and pass through checkbounds option): |
| 513 |
|
adjust_nlfs.cs-32x32x1 adjustment.128x64x1 adjustment.cs-32x32x1 |
| 514 |
|
exp0 exp1 exp2 exp4 exp5 hs94.cs-32x32x5 hs94.128x64x5 hs94.1x64x5 |
| 515 |
|
global_ocean.90x40x15 global_with_exf global_ocean_pressure |
| 516 |
|
inverted_barometer solid-body.cs-32x32x1 |
| 517 |
|
(high order AdvScheme and/or multiDimAd works with Olx=Oly=2 ? not sure) |
| 518 |
|
|
| 519 |
|
checkpoint48d_post |
| 520 |
|
o in preparation for r*: |
| 521 |
|
a) use pre-computed gradient of hydrostatic potential: |
| 522 |
|
changes in timestep.F & mom_cdscheme.F affects results of ideal_2D_oce |
| 523 |
|
b) move phi0surf from calc_phi_hyd to calc_grad_phi_hyd: |
| 524 |
|
=> affects results of glob_oce_pressure (different truncation error) |
| 525 |
|
update output.txt of ideal_2D_oce & global_ocean_pressure |
| 526 |
|
|
| 527 |
|
checkpoint48d_pre |
| 528 |
|
o in preparation for r*: |
| 529 |
|
new S/R (calc_grad_phi_hyd.F) to compute Hydrostatic potential gradient. |
| 530 |
|
pass the 2 comp. of the grad. as arguments to momentum S/R. |
| 531 |
|
but for the moment, only used if it does not change the results. |
| 532 |
|
o add finite volume form of calc_phi_hyd for buoyancyRelation OCEANIC & OCEANICP |
| 533 |
|
|
| 534 |
|
checkpoint48c_post |
| 535 |
|
Modifications in treatment of initial flux forcing controls |
| 536 |
|
to avoid extra storing of flux fields. |
| 537 |
|
|
| 538 |
|
checkpoint48c_pre |
| 539 |
|
o Added tidal_basin_2d experiment (currently 1D!) |
| 540 |
|
o can use r* Coordinate with OBC (but Orlanski Rad. BC not yet implemented) |
| 541 |
|
|
| 542 |
|
checkpoint48b_post |
| 543 |
|
o r* coordinate added in #ifdef NONLIN_FRSURF block. |
| 544 |
|
(modification to pressure gradient not yet implemented) |
| 545 |
|
o mom_fluxform: new S/R mom_calc_rtrans.F computes vertical transports |
| 546 |
|
(for U & V) that are used for vertical advection of momentum. |
| 547 |
|
|
| 548 |
|
checkpoint48a_post |
| 549 |
|
o In preparation for r*, use temp. array to compute vertical transport |
| 550 |
|
in flux-form momentum pkg. => change results of few test-exp. |
| 551 |
|
Update output of: exp4, exp5, front_relax, global_ocean_pressure, |
| 552 |
|
lab_sea, natl_box & plume_on_slope |
| 553 |
|
|
| 554 |
|
checkpoint48 |
| 555 |
|
o fix small bug that was causing lot of warning (TIMER_STOP 'UPDATE_CG2D') |
| 556 |
|
|
| 557 |
|
checkpoint47j_post |
| 558 |
|
o add new exp. (ideal_2D_oce) to test "exotic" parameters and options. |
| 559 |
|
o moved adexch from forward_step to addummy_in_stepping |
| 560 |
|
o added exch in ctrl_map_... |
| 561 |
|
o aveFreq.=0. at end of cost_final to avoid overwrite in |
| 562 |
|
reverse checkpointing loop |
| 563 |
|
o Yet more changes in gmredi: |
| 564 |
|
* adgmredi_calc_tensor |
| 565 |
|
avoiding all recomputation of gmredi_slope_limit |
| 566 |
|
* adgmredi_x/y/rtransport |
| 567 |
|
added flag for excessive storing to avoid recomp. of |
| 568 |
|
u/v/rtans, dTdx/y/z |
| 569 |
|
-> this is not really necessary and very memory-consuming |
| 570 |
|
* adgmredi_slope_psi: |
| 571 |
|
consistency with gmredi_slope_limit in treatment of GM_slopeSqCutoff |
| 572 |
|
* gmredi_slope_limit |
| 573 |
|
re-activated full calculation of taperfct for case 'ac02' |
| 574 |
|
o updating verification/ adjoints of carbon, global_ocean.90x40x15 |
| 575 |
|
|
| 576 |
|
checkpoint47i_post |
| 577 |
|
o GM_EXCLUDE_() replace GM_TAPER_(): by default, all the code is compiled. |
| 578 |
|
o add GM_Small_Number & GM_slopeSqCutoff as run-time parameters (data.gmredi) |
| 579 |
|
default values = 1.D-12 & 1.D+48 (=> give same results as checkpoint47f_post) |
| 580 |
|
o cg2dTargetResWunit: define tolerance using deltaTmom (and not deltaTfreesurf) |
| 581 |
|
o gmredi: fix few bugs. |
| 582 |
|
|
| 583 |
|
checkpoint47h_post (duplicate tag for PH's c48 tag, in order to move c48) |
| 584 |
|
This will be a good checkpoint to plug into the ecco-branch. |
| 585 |
|
o few modif.'s to get latest version adjointed |
| 586 |
|
(mainly kick out code in ini_linear_phisurf) |
| 587 |
|
o modif's to run adjoint with exactConserv |
| 588 |
|
o case GM_BOLUS_ADVEC should be cleaned |
| 589 |
|
S/R gmredi_slope_psi should be cleaned |
| 590 |
|
o verification/carbon now has exactConserv=.TRUE. |
| 591 |
|
|
| 592 |
|
checkpoint47g_post |
| 593 |
|
o time-average AIM output: becomes independent from statvars time-average |
| 594 |
|
(can be used with #undef ALLOW_TIMEAVE) ; add new variables (e.g., RH) |
| 595 |
|
o After TAF bug fix: |
| 596 |
|
Tested adjoint of gmredi package. |
| 597 |
|
Tests were done with checkpoint47 rather than with latest |
| 598 |
|
checkpoint47f_post since the latter is broken for the adjoint |
| 599 |
|
verification/carbon/ contains both ADM and TLM gradient checks. |
| 600 |
|
Here they are, before they get changed/lost/stolen. |
| 601 |
|
Mostly modif.'s to fix numerical sensitivities. |
| 602 |
|
Gradient checks OK for |
| 603 |
|
- GM_taper_scheme: |
| 604 |
|
* clipping |
| 605 |
|
* ac02 |
| 606 |
|
* linear |
| 607 |
|
* glw91 |
| 608 |
|
* dm95 |
| 609 |
|
* ldd97 |
| 610 |
|
- GMREDI_OPTIONS: |

|
* GM_VISBECK_VARIABLE_K |
| 612 |
|
* GM_NON_UNITY_DIAGONAL |
| 613 |
|
* GM_EXTRA_DIAGONAL |
| 614 |
|
* GM_BOLUS_ADVEC |
| 615 |
|
in conjunction with data.gmredi parameters to be checked in |

- verification/lab_sea default experiment now uses |
| 628 |
|
pkg/gmredi, pkg/kpp, pkg/seaice, and pkg/exf |
| 629 |
|
|
| 630 |
|

|
at the bottom boundary had an erroneous half slip boundary condition |
| 636 |
|
o added bottom drag and no slip boundary condition capabilities to |
| 637 |
|
oceanic pressure coordinates code |
| 638 |
|
o added new verification experiment global_ocean_pressure, this experiment is |
| 639 |
|
also described in the tutorial section of the manual |
| 640 |
|
checkpoint47d_pre |
| 641 |
|
|
| 642 |
|
checkpoint47c_post |
| 643 |
|
o Added a verification experiment for a global cubed-sphere ocean run |
| 644 |
|
- verification/global_ocean.cubed32x32x30 |
| 645 |
|
- uses pkg/therm_seaice and pkg/bulk_forcing |
| 646 |
|
|
| 647 |
|
o allow to run AIM physics with SPEEDY input files (from Franco Molteni) |
| 648 |
|

| 649 |
|
when using P-coordinate; only implemented for atmospheric config. |
| 650 |
|
o OCEANICP & realFreshWater: include P-E direct effect on wVel ; |
| 651 |
|
NOTES: requires option NONLIN_FRSURF to be "#define". |
| 652 |
|
o update advect_xz/results/output.txt (left from checkpoint44g_post) |
| 653 |
|
|

| 669 |
|
- added test of thermodynamics parallelization |
| 670 |

checkpoint47a_post |
| 672 |
|
o new pkg: aim_v23 |
| 673 |
|
= F. Molteni atmos.physics (SPEEDY, ver23) adapted to MITgcm. |
| 674 |
|
for now, keep the same surface forcing as before. |
| 675 |
|
- Part-Cell implemented into AIM; check that Heat & Water are conserved |
| 676 |
|
- aim.5l_cs: use new aim pkg (run 10yr & get better results than before) |
| 677 |
|
- aim.5l_LatLon & aim.5l_Equatorial_Channel are still using old aim pkg |
| 678 |
|
o add diagnostic of surface correction term in monitor output |
| 679 |
|
|
| 680 |
|
o bulk_force and therm_seaice |
| 681 |
|
- Two packages: bulk_force (Bulk forcing) |
| 682 |
|
and therm_seaice (thermodynamic_seaice) - adopted from LANL CICE.v2.0.2 |
| 683 |
|
- Earlier integration from Stephaine Dutkiewicz |
| 684 |
|
and Patrick Heimbach. |
| 685 |
|
- Two ifdef statements for compile time, |
| 686 |
|
ALLOW_THERM_SEAICE and ALLOW_BULK_FORCE |
| 687 |
|
|
| 688 |
|
checkpoint47 |
| 689 |
|
differentiable version of checkpoint46n_post |
| 690 |
|
o bug fix in quasihydrostaticterms |
| 691 |
|
o * "clean" adjoint code (in terms of extensive recomputations) |
| 692 |
|
can now be obtained for all GMREDI options (i.e. for |
| 693 |
|
- GM_VISBECK_VARIABLE_K |
| 694 |
|
- GM_NON_UNITY_DIAGONAL |
| 695 |
|
- GM_EXTRA_DIAGONAL |
| 696 |
|
- GM_BOLUS_ADVEC ) |
| 697 |
|
* However, wrong gradient check problem remains unsolved. |
| 698 |
|
* New CPP options have been introduced for different |
| 699 |
|
tapering schemes |
| 700 |
|
o external_fields_load now part of differentiation list |
| 701 |
|
o pressure needs multiple storing; |
| 702 |
|
would be nice to have store_pressure at beginning or |
| 703 |
|
end of forward_step, e.g. by having phiHyd global (5-dim.) |
| 704 |
|
(NB: pressure is needed for certain cases in find_rho, |
| 705 |
|
which is also invoked through convective_adjustment). |
| 706 |
|
o recomputations in find_rho for cases |
| 707 |
|
'JMD95'/'UNESCO' or 'MDJWF' are OK. |
| 708 |
|
o #define ATMOSPHERIC_LOADING should be differentiable |
| 709 |
|
o ini_forcing shifted to begining of initialise_varia |
| 710 |
|
o Incorporating QNVS line search routines into MITgcm |
| 711 |
|
(this is separate code, and therefore not under pkg) |
| 712 |
|
lsopt/, optim/ |
| 713 |
|
o Updated verification/carbon/ |
| 714 |
|
- #define GM_VISBECK_VARIABLE_K |
| 715 |
|
- GM_taper_scheme = 'ldd97' |
| 716 |
|
|
| 717 |
|
checkpoint46n_post |
| 718 |
|
Merging from release1_p8: |
| 719 |
|
o verification/natl_box: |
| 720 |
|
updating new external_fields_load routine |
| 721 |
|
o New package: pkg/seaice |
| 722 |
|
Sea ice model by D. Menemenlis (JPL) and Jinlun Zhang (Seattle). |
| 723 |
|
The sea-ice code is based on Hibler (1979-1980). |
| 724 |
|
Two sea-ice dynamic solvers, ADI and LSR, are included. |
| 725 |
|
In addition to computing prognostic sea-ice variables and diagnosing |
| 726 |
|
the forcing/external data fields that drive the ocean model, |
| 727 |
|
SEAICE_MODEL also sets theta to the freezing point under sea-ice. |
| 728 |
|
The implied surface heat flux is then stored in variable |
| 729 |
|
surfaceTendencyTice, which is needed by KPP package (kpp_calc.F and |
| 730 |
|
kpp_transport_t.F) to diagnose surface buoyancy fluxes and for the |
| 731 |
|
non-local transport term. Because this call precedes model |
| 732 |
|
thermodynamics, temperature under sea-ice may not be "exactly" at |
| 733 |
|
the freezing point by the time theta is dumped or time-averaged. |
| 734 |
|
N.B.: fairly large differences in accuracy occur across |
| 735 |
|
different platforms/compilers; comparison between |
| 736 |
|
g77 (Linux) and F77 (SGI Origin 2000/MIPSpro) |
| 737 |
|

| 745 |
|
o GAD: |
| 746 |
|
- generated new common blocks to account for call of |
| 747 |
|
same gad routines with differing traceridentities |
| 748 |
|
(needed to modify tracerIdentity indices in GAD.h) |
| 749 |
|
- generated separate common blocks for case useCubedSphereExchange |
| 750 |
|
(Department of Futurology) |
| 751 |
|
- parameter lists to gmredi_?transport: added tracerIdentity |
| 752 |
|
- added new key indices to tamc.h |
| 753 |
|
o external_fields_load: |
| 754 |
|
- added this routine to TAF list |
| 755 |
|
- needed to make some common blocks global and additional storing |
| 756 |
|
along the same lines as exf package (checkpoint_lev?_directives.h) |
| 757 |
|
o exf: |
| 758 |
|
updated external forcing package |
| 759 |
|
- bug fixes carried over from ecco-branch |
| 760 |
|
(missing OBCS_OPTIONS.h in two routines) |
| 761 |
|
- enable easy to use "no forcing". |
| 762 |
|
- added exf I/O for atmospheric loading |
| 763 |
|
- added exf I/O for runoff data |
| 764 |
|
- transfered scaling between exf <-> MITgcm to exf namelist |
| 765 |
|
o Adding new verification experiment global_with_exf. |
| 766 |
|
This verification experiment is almost identical to the |
| 767 |
|
global_ocean.90x40x15 experiment, except that it uses |
| 768 |
|
the exf (and cal) package instead of the |
| 769 |
|
external_fields_load routine (cf README file). |
| 770 |
|
|
| 771 |
|
checkpoint46m_post |
| 772 |
|
o modified testscript to return -- when there are no lines of "%MON" output |
| 773 |
|
o added new flag "quasiHydrostatic" for QH mode |
| 774 |
|
and new routine quasihydrostaticterms() |
| 775 |
|
o added 2*Omega*Cos(phi)*W to u equations (non-hydrostatic Coriolis term) |
| 776 |
|
New routine: mom_u_coriolis_nh() |
| 777 |
|
o fixed sign of non-hydrostatic metric terms in u and v equations. |
| 778 |
|
Depend on correct sign of gravitySign. |
| 779 |
|
o added work.pc* to .cvsignore in aim directories using ifc |
| 780 |
|
o introduced flag for controllin non-hydrostatic metric terms |
| 781 |
|
o removed gravitySign from PARM04 |
| 782 |
|
o switched to g77/ifc from pgf77 in aim experiments |
| 783 |
|
|
| 784 |
|
checkpoint46l_post |
| 785 |
|
o made convective adjustment work with pressure coordinates: |
| 786 |
|
- changed the direction of k-loop in convective_adjustment.F for the |
| 787 |
|
case of pressure coordinates (OCEANICP,ATMOSPHERIC buoyancyRelation) |
| 788 |
|
- adjusted the reference pressure k-index in convective_adjustment.F |
| 789 |
|
- adjusted the convection condition in convect.F (in analogy to |
| 790 |
|
calc_ivdc.F) |
| 791 |
|
- convective_adjustment no longer computes anything on the halos |
| 792 |
|
- removed the warnings about negative salinity from find_rho.F and |
| 793 |
|
find_alpha.F; instead the new routine look_for_neg_salinity, called |
| 794 |
|
at the beginning of find_rho, find_alpha, and find_beta, does a |
| 795 |
|
check of the entire slice, if CPP-option |
| 796 |
|
CHECK_SALINITY_FOR_NEGATIVE_VALUES is defined |
| 797 |
|
checkpoint46l_pre |
| 798 |
|
|
| 799 |
|
checkpoint46k_post |
| 800 |
|
o fixed the verification/global_ocean.90x40x15 experiment: |
| 801 |
|
- new bathymetry (the world according to A., JMC, and M.) |
| 802 |
|
- new initial fields and forcing fields (*.bin files) |
| 803 |
|
- new POLY3.COEFFS (for the next release one should switch to a full |
| 804 |
|
equation of state: JMD95P or MDJWF) |
| 805 |
|
- fixed several errors and redundancies in the data file |
| 806 |
|
- experiment uses looped cells |
| 807 |
|
- added matlab directory with diagnostic scripts for plotting of output |
| 808 |
|
|
| 809 |
|
o S/R aim_initialise.F replace S/R aim_init from file aim_do_inphys.F: |
| 810 |
|
- read AIM physics parameters from a file (data.aimphys) |
| 811 |
|
- set defaults values = F.Molteni paper (Clim.Dyn., 2002) |
| 812 |
|
|
| 813 |
|
checkpoint46j_post |
| 814 |
|
o split calc_exact_eta in 2 S/R : integr_continuity & update_etaH |
| 815 |
|
o move wVel computation at the end of the time step, in S/R integr_continuity |
| 816 |
|
o create specific S/R to exchange T,S before DYNAMICS (for stagger time step) |
| 817 |
|
o update timeave pkg for wVel diagnostic. |
| 818 |
|
checkpoint46j_pre |
| 819 |
|
|
| 820 |
|
checkpoint46i_post |
| 821 |
|
o Clean up AIM package (and keep the results unchanged): |
| 822 |
|
include CPP_OPTION and use IMPLICT NONE in all routines ; |
| 823 |
|
declare all the variables _RL ; use _d 0 for all numerical constants. |
| 824 |
|
use ifdef ALLOW_AIM everywhere. And now AIM can be used with g77 ! |
| 825 |
|
|
| 826 |
|
checkpoint46h_post |
| 827 |
|
o cleaned up the use of rhoNil and rhoConst. |
| 828 |
|
- rhoNil should only appear in the LINEAR equation of state, everywhere |
| 829 |
|
else rhoNil is replaced by rhoConst, e.g. find_rho computes rho-rhoConst |
| 830 |
|
and the dynamical equations are all divided by rhoConst |
| 831 |
|
o introduced new parameter rhoConstFresh, a reference density of fresh |
| 832 |
|
water, to remove the fresh water flux's dependence on rhoNil. The default |
| 833 |
|
value is 999.8 kg/m^3 |
| 834 |
|
o cleanup up external_forcing.F and external_forcing_surf.F |
| 835 |
|
- can now be used by both OCEANIC and OCEANICP |
| 836 |
|
checkpoint46h_pre |
| 837 |
|
|
| 838 |
|
Added code to convert surface volume flux (fresh water) into |
| 839 |
|
a mass flux when using P coordinates in the ocean (OCEANICP). |
| 840 |
|
Note: It assumes you have set rho0=rhoConst=density of fresh water. |
| 841 |
|
|
| 842 |
|
checkpoint46g_post |
| 843 |
|
o Include a new diagnostic variable phiHydLow for the ocean model |
| 844 |
|
- in z-coordinates, it is the bottom pressure anomaly |
| 845 |
|
- in p-coordinates, it is the sea surface elevation |
| 846 |
|
- in both cases, these variable have global drift, reflecting the mass |
| 847 |
|
drift in z-coordinates and the volume drift in p-coordinates |
| 848 |
|
- included time averaging for phiHydLow, be aware of the drift! |
| 849 |
|
o depth-dependent computation of Bo_surf for pressure coordinates |
| 850 |
|
in the ocean (buoyancyRelation='OCEANICP') |
| 851 |
|
- requires a new routine (FIND_RHO_SCALAR) to compute density with only |
| 852 |
|
Theta, Salinity, and Pressure in the parameter list. This routine is |
| 853 |
|
presently contained in find_rho.F. This routine does not give the |
| 854 |
|
correct density for 'POLY3', which would be a z-dependent reference |
| 855 |
|
density. |
| 856 |
|
o cleaned up find_rho |
| 857 |
|
- removed obsolete 'eqn' from the parameter list. |
| 858 |
|
o added two new verification experiments: gop and goz |
| 859 |
|
(4x4 degree global ocean, 15 layers in pressure and height coordinates) |
| 860 |
|
checkpoint46g_pre |
| 861 |
|
|
| 862 |
|
checkpoint46f_post |
| 863 |
|
o Enable tangent linear (forward mode) gradient checks: |
| 864 |
|
- extended active file handling to g_... files |
| 865 |
|
- added TANGENT_SIMULATION to theSimulationMode |
| 866 |
|
- extended grdchk package accordingly |
| 867 |
|
o added tangent linear setup in verification/carbon/code_ftl |
| 868 |
|
o added adjoint setup in verification/front_relax/code_ad |
| 869 |
|
|
| 870 |
|
checkpoint46e_post |
| 871 |
|
o Added new equation of state -> MDJWF |
| 872 |
|
- EOS of McDougall et al., 2002, JAOT, submitted |
| 873 |
|
- caveat: the equation of state is only valid for a smaller (more |
| 874 |
|
realistic?) range of values than JMD95P/Z and UNESCO |
| 875 |
|
- added masks to the calculation of pressure in store_pressure |
| 876 |
|
- added more check values for density in check_eos (ini_eos.F), some of |
| 877 |
|
the old check values are out of the range of the MDJWF-eos, so don't |
| 878 |
|
expect perfect matches for those |
| 879 |
|
checkpoint46e_pre |
| 880 |
|
|
| 881 |
|
checkpoint46d_post |
| 882 |
|
o fixed store_pressure to work with both buoyancy relation = 'OCEANIC' and |
| 883 |
|
'OCEANICP', also initialised field pressure correctly in ini_eos in the |
| 884 |
|
case of pressure coordinates. eosType='JMD95Z' in |
| 885 |
|
combination with buoyancyRelation='OCEANICP' now causes an error. |
| 886 |
|
o Changed p = pressure(i,j,k,bi,bj) to p = pressure(i,j,kRef,bi,bj) |
| 887 |
|
in find_alpha/beta. |
| 888 |
|
checkpoint46d_pre |
| 889 |
|
|
| 890 |
|
o Changed p = pressure(i,j,k,bi,bj) to p = pressure(i,j,kRef,bi,bj) |
| 891 |
|
so that JMD95Z and JMD95P give approptiate static stability in find_rho. |
| 892 |
|
|
| 893 |
|
checkpoint46c_post |
| 894 |
|
o Changes necessary for ocean in p-coordinates |
| 895 |
|
- Added new buoyancy relation = 'OCEANICP' |
| 896 |
|
- Added new parameters = gravitySign (this used to be contained inside |
| 897 |
|
the factor dRdZ which I added when we first switched to R coordinates). |
| 898 |
|
X GM/Redi is not compatible (yet) |
| 899 |
|
X bottom drag and no-slip need to be debugged. |
| 900 |
|
checkpoint46c_pre |
| 901 |
|
|
| 902 |
|
checkpoint46b_post |
| 903 |
|
o Added new equation of state -> JMD95Z and JMD95P |
| 904 |
|
- EOS of Jackett and McDougall, 1995, JAOT |
| 905 |
|
- moved all EOS parameters into EOS.h |
| 906 |
|
- new routines ini_eos.F, store_pressure.F |
| 907 |
|
o Added UNESCO EOS, but not recommended because it requires |
| 908 |
|
in-situ temperature (see JMD95) |
| 909 |
|
o Modified formatting for knudsen2.f in utils/knudsen2 and added |
| 910 |
|
unesco.f to be used with POLY3 |
| 911 |
|
checkpoint46b_pre |
| 912 |
|
|
| 913 |

|
o Changed hFacC to _hFacC in calc_phi_hyd.F |
| 918 |
|
o Added SHORTWAVE_HEATING to some files for consistency |
| 919 |
|
checkpoint46a_pre |
| 920 |
|
|
| 921 |
|
checkpoint46 |
| 922 |

|
- added Eliassen Palm cost hooks |
| 930 |
|
- modif's of existing cost functions |
| 931 |
|
o Adjoint-related bug fixes in kpp: |
| 932 |
|
- kpp_calc: sore of kpphbl avoids recomputation/call to S/R kppmix |
| 933 |
|
- kpp_routines: store of Rib avoids partial recomputation bug of TAF. |
| 934 |
|
o autodiff package |
| 935 |
|
- flow directives: |
| 936 |
|
+ new for S/R do_the_model_io |
| 937 |
|
+ enhanced for S/R checkpoint |
| 938 |
|
+ new gmredi.flow |
| 939 |

disable adcommon.h/g_common.h by default. |
| 941 |
|
- fixed problem for adjoint of global_max |
| 942 |
|
o modified verification/carbon/ |

| 945 |
|
o cleaned TAF keys iikey, idkey (dynamics.F, thermodynamics.F) |
| 946 |
|
o incorporated hooks for sponge layer code (external_forcing.F) |
| 947 |
|
|
| 948 |
|
checkpoint45d_post |
| 949 |
|
o import 2 fixes from release1_p5 (CG2D.h & packages_readparms.F) |
| 950 |
|
o use recip_dx*,recip_dy* instead of /dx*,/dy* in orlanski_E,W,N,S |
| 951 |
|
(affects plume_on_slope "cg2d" output) |
| 952 |
|
o add new parameter deltaTfreesurf for free-surface time stepping |
| 953 |
|
o exchange gT,gS when using staggerTimeStep & GM & Oly<4 |
| 954 |
|
o NONLIN_FRSURF: rescale gNm1 to get a better conservation with A-B |
| 955 |
|
o change phiMin in exp1 (to agree with documentation) |
| 956 |
|
o add new flags: |
| 957 |
|
- T,S forcing inside/outside Adams-Bashforth |
| 958 |
|
- turn off temp,salt advection and/or forcing |
| 959 |
|
- for each tracer, define internal flag for multiDimAdvection & A-B |
| 960 |
|
o monitor: change definition of KE to check conservation of Energy |
| 961 |
|
|
| 962 |
|
checkpoint45c_post |
| 963 |
|
o Removed f90 comments ("!") |
| 964 |
|
o Modified initialisations to enable exf package for MITgcm |
| 965 |
|
(without invoking ECCO_PACKAGE). |
| 966 |
|
o modifications to gradient check package (Martin Losch) |
| 967 |
|
- enable centered differences |
| 968 |
|
- modified format of standard output |
| 969 |
|
|
| 970 |
|
checkpoint45b_post |
| 971 |
|
o cleaned exchange calls in cg2d |
| 972 |
|
o Included CPP option ALLOW_AUTODIFF_MONITOR in forward_step |
| 973 |
|
o included CPP option SINGLE_LAYER_MODE in thermodynamics |
| 974 |
|
to configure barotropic setup (Martin Losch) |
| 975 |
|
o moved some initialisations within bi,bj loop in dynamics |
| 976 |
|
(TAF flow dependency) |
| 977 |
|
o in initialise_varia, moved call packages_init_variables |
| 978 |
|
before convective_adjustment_init |
| 979 |
|
(corresponding adjustment of TAF tape initialisation). |
| 980 |
|
o in calc_diffusivity/calc_viscosity extended domain to full overlap. |
| 981 |
|
|
| 982 |

| 984 |
|
o specific exchange for X-slice domain (case Ny=1) |
| 985 |
|
o argument futureIter of S/R obcs_calc missing in exp4 & internal_wave /code |
| 986 |
|
o solve_for_pressure : set cg2d_x to zero where OBCS are applied |
| 987 |
|
|
| 988 |
|
checkpoint44h_post = checkpoint45 |
| 989 |
|
o Fix to restore differentiability: |
| 990 |
|
place at which packages_init_variables is called in |
| 991 |
|
initialise_varia is crucial for reverse control flow. |
| 992 |
|
o modifications in GMRedi to enable stable adjoint |
| 993 |

|
+ Implemented so far: |
| 1017 |
|
- basic forward algorithm (time-stepping, advection, diffusion, convection) |
| 1018 |
|
- I/O and checkpointing |
| 1019 |
|
- GM/Redi *but* using the GM/Redi coefficient of Salt |
| 1020 |
|
+ Not implemented so far: |
| 1021 |
|
- KPP |
| 1022 |
|
- OBCS |
| 1023 |
|
+ No specific example supplied (yet) but global_ocean.90x40x15 has the |
| 1024 |
|
necessary data.ptracer file. Simply use -enable=ptracers and uncomment |
| 1025 |
|
line in data.pkg. |
| 1026 |
|
+ This package is disabled by default since it increases storage. |

| 1123 |
|
o new package rw/ |
| 1124 |
|
Added method for dumping intermediate local arrays: |
| 1125 |
|
mdsio_writetile - same as mdsio_writefield except works from inside |
| 1126 |
|
bi,bj loop |
| 1127 |
|
mdsio_writelocal - same as mdsio_writetile except works for local |
| 1128 |
|
arrays |
| 1129 |
|
write_local_r? - higher-level wrapper for mdsio_writelocal |
| 1130 |
|
Controlled by diagFreq. Defaults to zero (ie. no dumps) |
| 1131 |
|
Example given at end of mom_vecinv.F that dumps some local arrays. |
| 1132 |
|
o replaced calc_mom_rhs.F by mom_fluxform.F/mom_vecinc.F to |
