94
95 release1_p8
96 o verification/natl_box:
97 updating new external_fields_load routine
98 o New package: pkg/seaice
99 Sea ice model by D. Menemenlis (JPL) and Jinlun Zhang (Seattle).
100 The sea-ice code is based on Hibler (1979-1980).
101 Two sea-ice dynamic solvers, ADI and LSR, are included.
102 In addition to computing prognostic sea-ice variables and diagnosing
103 the forcing/external data fields that drive the ocean model,
104 SEAICE_MODEL also sets theta to the freezing point under sea-ice.
105 The implied surface heat flux is then stored in variable
106 surfaceTendencyTice, which is needed by KPP package (kpp_calc.F and
107 kpp_transport_t.F) to diagnose surface buoyancy fluxes and for the
108 non-local transport term. Because this call precedes model
109 thermodynamics, temperature under sea-ice may not be "exactly" at
110 the freezing point by the time theta is dumped or time-averaged.
111 N.B.: fairly large differences in accuracy occur across
112 different platforms/compilers; comparison between
113 g77 (Linux) and F77 (SGI Origin 2000/MIPSpro)
114 generated output gives:
115 T S U V
116 C D M c m s m s m s m s
117 n p a R g m m e . m m e . m m e . m m e .
118 f n k u 2 i a a d i a a d i a a d i a a d
119 g d e n d n x n . n x n . n x n . n x n .

122
123 release1_p7
124 o GAD:
125 - generated new common blocks to account for call of
126 same gad routines with differing traceridentities
127 (needed to modify tracerIdentity indices in GAD.h)
128 - generated separate common blocks for case useCubedSphereExchange
129 (Department of Futurology)
130 - parameter lists to gmredi_?transport: added tracerIdentity
131 - added new key indices to tamc.h
132 o external_fields_load:
133 - added this routine to TAF list
134 - needed to make some common blocks global and additional storing
135 along the same lines as exf package (checkpoint_lev?_directives.h)

316 arrays
317 write_local_r? - higher-level wrapper for mdsio_writelocal
318 Controlled by diagFreq. Defaults to zero (ie. no dumps)
319 Example given at end of mom_vecinv.F that dumps some local arrays.
320 o replaced calc_mom_rhs.F by mom_fluxform.F/mom_vecinc.F to
321 control flux-form versus vector invariant code.
322 Switch is runtime flag vectorInvariantMomentum (defaults to false)
323 or genmake -DISABLE ...
324 o TAMC-related update to cope with mom_fluxform.F/mom_vecinc.F
325 (additional storing is now needed for case vecinv;
326 currently nothing implemented to switch this storing off
327 in case fluxform is used since no CPP flag available).
328

347 o re-generated *all* output since almost all output is modified by this
348 change (sorry but we've been putting this one off for about 2 years)
349 + natl_box, aim.5l_Equatorial_Channel and aim.5l_zon-ave were
350 *not* regenerated since they are already out of date and I don't
351 want to create the impression that they are suddenly working.
352 o removed KAP stuff for DEC's
353 o modified/added many .cvsignore files in */code and */input
354 o added new expt "solid-body.cs-32x32x1"
355 + this uses an alternative form of ini_curvilinear_grid.F which
356 is not necessarily any better than the current one...
357
358 checkpoint40pre4
359 o added re-initialisations of utrans,vtrans,rtrans in

383 o Enabled "sliced" (xz-,yz-) exchanges, needed for obcs.
384 o Included following packages:
385 cal: calendar
386 exf: external forcing
387 ecco: essential routines to control use of cal, exf

398
399 checkpoint37
400 o mdsio.F routine split and packaged in pkg/mdsio
401 (mdsio.F and mdsio_gl.F still exist in eesupp/src but are not
402 used unless genmake -disable=mdsio)
403 o allow a more precise surface-geopotential gradient for the atmosphere
404 taking into account the change in space of Alpha (=1/rho) at the surface.
405 o variable "etaN" (replace cg2d_x) is the surface R-anomaly [r unit]
406 (ocean: sea surface height [m] / atmos: surface pressure anomaly [Pa])
407 o Change units: Phi_Hydrostatic (=phiHyd), Phi_Surface(=cg2d_x) and
408 Phi_NonHydrostatic (=cg3d_x), all have now the dimension of a potential
409 [m2/s2] (pressure/rhoConst in the ocean ; Geo-Potential in the atmosphere).
410 o Time-Average diagnostics defined as a pseudo package "timeave".
411 o pickup files : old pickup (before c35) did not work with new code (c35
412 and after) unless activating 2 commented lines in initialise-varia.
413 o Non-Hydrostatic pickup file Pb fixed.
414 o bug with Rigid-lid version (since c35) fixed.
415
416 checkpoint36
417 o implement Crank-Nickelson barotropic time-stepping

437 o Added mdsio_gl.F for ECCO purposes.
438
439 checkpoint33
440 o Fixed bug in lower BC in impldiff.F
441 o Fixed confusion about units of forcing arrays in FFIELDS.h
442 namely Fu,Fv,Qnet,Qsw,EmPmR:
443 - Removed verification/natl_box/code/external_fields_scale.F
444 (did not differ from that in model/src)
445 - Changed units of fu,fv,Qnet,Qsw,EmPmR back to proper units
446 (see FFIELDS.h for description)
447 - Scale fu,fv,Qnet,Qsw,EmPmR when used in external_forcing_surf.F,
448 kpp_calc.F and kpp_transport_t.F
449 - Removed model/src/external_fields_scale.F and calls to it
450 - verification/natl_box uses flux data with "atmospheric" sign so
451 a special version of external_fields_load.F is used to
452 change the data as it's read in. This way, the arrays
453 have the right units and signs at all times tha a user could
454 possibly use them.
455 o Corrected genmake to delete a temporary file during configuration
456
457 checkpoint32
458 o Scaling of forcing fields moved from external_forcing.F to
459 external_fields_scale.F, called directly after loading fields.

461 extra subroutine.
462 o impldiff.F changed to avoid storing by TAMC of huge intermediate
463 fields.
464 o Changes in GMRedi to comply with packaging structure.
465 o Modifications and bug fixes in KPP package.
466 o Verification experiment for KPP added (verification/nat_box/)
467
468 checkpoint31
469 o Packages interface brought in line with defined standard
470 -> new routines packages_...F
471 -> changes in initialise_fixed.F, initialise_varia.F
472 -> enables initialisation interface for ECCO package
473 o Rescaling of external forcing fields immediately after read
474 (removed from external_forcing.F)
475 -> new: surface_fields_scale.F
476 -> affects ini_foorcing.F, external_fields_load.F
477 o Computation of surface tendencies before tendency updates.
478 -> new: external_forcing_surf.F
479 o Change of variable names useGMRedi, useKPP, useECCO
480 o Further changes in dynamics.F, impldiff.F for TAMC
481 o Tested for experiments 0, 2, 4.

487 o New experiment for test OBCs (internal_wave)
488 o New output.txt in verification/exp4/results/
489 o Updates for KPP: calculation of viscosity corrected, new variables

494 checkpoint29
495 o packaged KPP and GM/Redi
496
497 checkpoint28
498 o Corrected initialization of hFacMin for difference vertical coordinates

507 included store directives and tape key computations required for TAMC.
508 o ALL TAMC related changes are between ifdef ALLOW_AUTODIFF_TAMC
509
510 checkpoint27
511 o fixed calc_isoslopes() to so that cancellation of terms in tensor
512 formulation works properly with variable resolution.
513 o restructured the calling tree between the_model_main() and dynamics()
514 o split initialise() into initialise_fixed() and initialise_varia()

516 in new routine ini_psurf()
517
518 checkpoint26

522 o cleaned up some unused and uninitialized variables
523 (helps when debugging with strict compile options)

532 o parameterization of convection by implicit vertical diffusion
533 o added a diagnostic of convective index
534 o moved call to calc_divg_hat() from dynamics() to solve_for_pressure()
535 (this is was partly for OBCs and NH but also in anticipation of
536 an explicit free-surface option)
537 o initial state input files for U and V
538
539 checkpoint24
540 o Removed some spurious "REAL"s
541 o Updated KPP to latest version from JPL

547
548 checkpoint22
549 o Made many small changes: implicit none, format(i5), etc...
550 o Introduced KPP mixing scheme (compiles and runs but *not* tested)
551
552 checkpoint21
553 o Introduced new I/O package that supports direct-access records (mdsio.F)
554 o Split-up mid-level I/O routines

556 o Finally removed the genmake.* scripts (everyone seems happy with genmake)
557
558 checkpoint20
559 o Tidied up open-boundaries some more

570 o Split default parameters out of ini_parms.F into set_defaults.F.
571
572 checkpoint18
573 o Further changes for optional code generation with
574 CPP - ugh!
575
576 checkpoint17
577 o Beginning to incorporating modularity
578 for supporting atmos. and ocean configs.
579 o Small changes for TAMC complinace
580 o New ultra simple test case. Barotropic box
581 configuration "exp0".
582
583 checkpoint16
584 o Minor changes to exchange routines to support
585 accumulation in reverse mode. Adjoint of an
586 assignment is an addition.
587 o Changes to support compilation by TAMC (LR(1)
588 syntax) and by g77 under Linux ( 72 character
589 limit ).
590
591 checkpoint15
592 Rewrote exchange routines to allow
593 o General tile <-> tile connectivity.
594 o TAMC reverse mode flag ( is this really needed? )
595 o Variable width overlap and exchange region widths.
596 o Hooks for sharing data via DMA, Arctic, Memory Channel,
597 shmput/shmget, VIA, SYSV shmem and every other cool
598 communication method.
599
600 checkpoint14
601 Consistent isomorphism chages made. These allow dynamical core
602 to support both pressure and meters as a vertical coordinate.
603
604 checkpoint13
605 Release which corrects global_max problem and a couple
606 of KGM time-averaging diagnostic errors. Also contains
607 a double-gyre experiment setup as well as the baseline
608 4 degree global template. The double gyre template is
609 organised to allow it to be applied automatically to
610 the baseline configuration.
611
612 branch-point-rdot
613 A few tidy-ups have been made bt the real point of this
614 check-point (excuse the pun) is to allow a branch to be
615 made for the purposes of adding the rDot alterations.
616 I don't want to commit the rDot to the main-trunk until
617 we've actually tested it...
618
