52 heimbach 1.53.2.14
53     release1_p8
54     o verification/natl_box:
55     updating new external_fields_load routine
56     o New package: pkg/seaice
57     Sea ice model by D. Menemenlis (JPL) and Jinlun Zhang (Seattle).
58     The sea-ice code is based on Hibler (1979-1980).
59     Two sea-ice dynamic solvers, ADI and LSR, are included.
60     In addition to computing prognostic sea-ice variables and diagnosing
61     the forcing/external data fields that drive the ocean model,
62     SEAICE_MODEL also sets theta to the freezing point under sea-ice.
63     The implied surface heat flux is then stored in variable
64     surfaceTendencyTice, which is needed by KPP package (kpp_calc.F and
65     kpp_transport_t.F) to diagnose surface buoyancy fluxes and for the
66     non-local transport term. Because this call precedes model
67     thermodynamics, temperature under sea-ice may not be "exactly" at
68     the freezing point by the time theta is dumped or time-averaged.
69     N.B.: fairly large differences in accuracy occur across
70 heimbach 1.53.2.15 different platforms/compilers; comparison between
71     g77 (Linux) and F77 (SGI Origin 2000/MIPSpro)
72     generated output gives:

82 heimbach 1.53.2.12 o GAD:
83     - generated new common blocks to account for call of
84     same gad routines with differing traceridentities

87     (Department of Futurology)
88     - parameter lists to gmredi_?transport: added tracerIdentity
89     - added new key indices to tamc.h
90     o external_fields_load:
91     - added this routine to TAF list
92     - needed to make some common blocks global and additional storing
93     along the same lines as exf package (checkpoint_lev?_directives.h)
94     o exf:
95     updated external forcing package
96     - bug fixes carried over from ecco-branch
97     (missing OBCS_OPTIONS.h in two routines)

105     the exf (and cal) package instead of the
106     external_fields_load routine (cf README file).

268 adcroft 1.48 checkpoint40pre8
269 heimbach 1.47 o new package rw/
270     Added method for dumping intermediate local arrays:
271     mdsio_writetile - same as mdsio_writefield except works from inside
272     bi,bj loop
273     mdsio_writelocal - same as mdsio_writetile except works for local
274     arrays
275     write_local_r? - higher-level wrapper for mdsio_writelocal
276     Controlled by diagFreq. Defaults to zero (ie. no dumps)
277     Example given at end of mom_vecinv.F that dumps some local arrays.
278     o replaced calc_mom_rhs.F by mom_fluxform.F/mom_vecinc.F to
279     control flux-form versus vector invariant code.
280     Switch is runtime flag vectorInvariantMomentum (defaults to false)
281     or genmake -DISABLE ...
282     o TAMC-related update to cope with mom_fluxform.F/mom_vecinc.F
283     (additional storing is now needed for case vecinv;
284     currently nothing implemented to switch this storing off
285     in case fluxform is used since no CPP flag available).
286 heimbach 1.46
287     checkpoint40pre7
288     o bug fix in dynamics.F
289     calc_viscosity called before k=1,Nr loop.

299     o Added diffkr, kapgm to control variables
300     o bug fix in gmredi_slope_limit for ldd97
301 adcroft 1.44
302     checkpoint40pre5
303     o proper initialization of Adams-Bashforth time stepping
304     + uses forward step for very first step of model (iter=0)
305     o re-generated *all* output since almost all output is modified by this
306     change (sorry but we've been putting this one off for about 2 years)
307     + natl_box, aim.5l_Equatorial_Channel and aim.5l_zon-ave were
308     *not* regenerated since they are already out of date and I don't
309     want to create the impression that they are suddenly working.
310     o removed KAP stuff for DEC's
311     o modified/added many .cvsignore files in */code and */input
312     o added new expt "solid-body.cs-32x32x1"
313     + this uses an alternative form of ini_curvilinear_grid.F which
314     is not necessarily any better than the current one...
315 heimbach 1.43
316     checkpoint40pre4
317     o added re-initialisations of utrans,vtrans,rtrans in
318     calc_common_factors which are crucial for TAF.

331     o Added gradient check package
332     o Added routines for passive tracer handling
333     o Added carbon sequestration sensitivity experiment
334    
335 heimbach 1.39 checkpoint39
336     o Modifications and fixes to support TAMC
337     (mainly missing or wrong directives)
338     o Corrected common blocks when fooling TAMC to produce adjoint I/O
339     in addummy_in_stepping
340     o Updated verification/vero/ (bug fixes in code/, correct pickups in input/)
341     o Enabled "sliced" (xz-,yz-) exchanges, needed for obcs.
342     o Included following packages:
343     cal: calendar
344     exf: external forcing
345     ecco: essential routines to control use of cal, exf
346     (NB: this is not the full ECCO environment)
347 heimbach 1.40 o disabled some packages by default in genmake
348 heimbach 1.39
349 heimbach 1.38 checkpoint38
350     o see notes_c37_adj.txt
351     o corrected wrong layer index in external_forcing_t
352     o replaced the_main_loop/forward_step by the_main_loop
353     o removed forceoutput from write_state
354     (replaced criteria for initial/final state)
355     o added runtime flag for pre-C35 pickups: usePickupBeforeC35
356 jmc 1.36
357 jmc 1.37 checkpoint37
358     o mdsio.F routine split and packaged in pkg/mdsio
359     (mdsio.F and mdsio_gl.F still exist in eesupp/src but are not
360     used unless genmake -disable=mdsio)
361     o allow a more precise surface-geopotential gradient for the atmosphere
362     taking into account the change in space of Alpha (=1/rho) at the surface.
363     o variable "etaN" (replace cg2d_x) is the surface R-anomaly [r unit]
364     (ocean: sea surface height [m] / atmos: surface pressure anomaly [Pa])
365     o Change units: Phi_Hydrostatic (=phiHyd), Phi_Surface(=cg2d_x) and
366     Phi_NonHydrostatic (=cg3d_x), all have now the dimension of a potential
367     [m2/s2] (pressure/rhoConst in the ocean ; Geo-Potential in the atmosphere).
368     o Time-Average diagnostics defined as a pseudo package "timeave".
369     o pickup files : old pickup (before c35) did not work with new code (c35
370     and after) unless activating 2 commented lines in initialise-varia.
371     o Non-Hydrostatic pickup file Pb fixed.
372     o bug with Rigid-lid version (since c35) fixed.
373    
374 jmc 1.36 checkpoint36
375 jmc 1.37 o implement Crank-Nickelson barotropic time-stepping
376 jmc 1.36 o recover Time-Average diagnostics
377     o fix Pb in checkpoint (PR#19)
378     o AIM become a standard package ; clean unused CPP_kees
379 jmc 1.35
380     checkpoint35
381     o subtantial rewrite of dynamics.f
382     o allows staggered time-stepping
383     o packaged obcs, aim (Atmospheric Physics), zonal_filt, shap_filt
384     o added bottom drag (linear + quadratic)
385 heimbach 1.33
386     checkpoint34
387     o Modified exchange routines for correct reverse simulation.
388     o Added verification output to comply with bug fix in impldiff.F
389     as of c33 (exp2, natl_box).
390     o Corrected store directives in dynamics.F
391     o Corrected array boundaries in impldiff.F
392     o Corrected array dimensions in gmredi.
393     Added temporary scalars to avoid storage by TAMC (gmredi, kpp).
394 heimbach 1.34 o Added routine GLOBAL_SUM_INT to global_sum.F
395 heimbach 1.33 o Added mdsio_gl.F for ECCO purposes.
396 adcroft 1.32
397     checkpoint33
398     o Fixed bug in lower BC in impldiff.F
399     o Fixed confusion about units of forcing arrays in FFIELDS.h
400     namely Fu,Fv,Qnet,Qsw,EmPmR:
401     - Removed verification/natl_box/code/external_fields_scale.F
402     (did not differ from that in model/src)
403     - Changed units of fu,fv,Qnet,Qsw,EmPmR back to proper units
404     (see FFIELDS.h for description)
405     - Scale fu,fv,Qnet,Qsw,EmPmR when used in external_forcing_surf.F,
406     kpp_calc.F and kpp_transport_t.F
407     - Removed model/src/external_fields_scale.F and calls to it
408     - verification/natl_box uses flux data with "atmospheric" sign so
409     a special version of external_fields_load.F is used to
410     change the data as it's read in. This way, the arrays

568     the baseline configuration.
569 adcroft 1.11
570     branch-point-rdot
571     A few tidy-ups have been made bt the real point of this
572     check-point (excuse the pun) is to allow a branch to be
573     made for the purposes of adding the rDot alterations.
574     I don't want to commit the rDot to the main-trunk until
575     we've actually tested it...
