6    release1_p7
7    o GAD:
8      - generated new common blocks to account for call of
9        same gad routines with differing traceridentities
10        (needed to modify tracerIdentity indices in GAD.h)

12        (Department of Futurology)
13      - parameter lists to gmredi_?transport: added tracerIdentity
14      - added new key indices to tamc.h
15    o external_fields_load:
16      - added this routine to TAF list
17      - needed to make some common blocks global and additional storing
18        along the same lines as exf package (checkpoint_lev?_directives.h)
19    o exf:
20      updated external forcing package
21      - bug fixes carried over from ecco-branch
22        (missing OBCS_OPTIONS.h in two routines)

28      This verification experiment is almost identical to the
29      global_ocean.90x40x15 experiment, except that it uses
30      the exf (and cal) package instead of the
31      external_fields_load routine (cf README file).

161      (mainly thermodynamics.F)
162    o New store directives for multi-dim. advection schemes

197                        bi,bj loop
198      mdsio_writelocal - same as mdsio_writetile except works for local
199                         arrays
200      write_local_r? - higher-level wrapper for mdsio_writelocal
201      Controlled by diagFreq. Defaults to zero (ie. no dumps)
202      Example given at end of mom_vecinv.F that dumps some local arrays.
203    o replaced calc_mom_rhs.F by mom_fluxform.F/mom_vecinc.F to
204      control flux-form versus vector invariant code.
205      Switch is runtime flag vectorInvariantMomentum (defaults to false)
206      or genmake -DISABLE ...
207    o TAMC-related update to cope with mom_fluxform.F/mom_vecinc.F
208      (additional storing is now needed for case vecinv;
209      currently nothing implemented to switch this storing off
210      in case fluxform is used since no CPP flag available).
211    
212    checkpoint40pre7

221    o corresponding split of calc_diffusivity into
222      calc_diffusivity, calc_viscosity
223      (kpp_calc_diff, kpp_calc_visc).
224    o Added diffkr, kapgm to control variables
225    o bug fix in gmredi_slope_limit for ldd97
226    
227    checkpoint40pre5
228    o proper initialization of Adams-Bashforth time stepping
229      + uses forward step for very first step of model (iter=0)
230    o re-generated *all* output since almost all output is modified by this
231      change (sorry but we've been putting this one off for about 2 years)
232      + natl_box, aim.5l_Equatorial_Channel and aim.5l_zon-ave were
233        *not* regenerated since they are already out of date and I don't
234        want to create the impression that they are suddenly working.
235    o removed KAP stuff for DEC's
236    o modified/added many .cvsignore files in */code and */input
237    o added new expt "solid-body.cs-32x32x1"
238      + this uses an alternative form of ini_curvilinear_grid.F which
239        is not necessarily any better than the current one...
240    
241    checkpoint40pre4
242    o added re-initialisations of utrans,vtrans,rtrans in
243      calc_common_factors which are crucial for TAF.

255    o Updated to latest branch of AJA, JMC
256    o Added gradient check package
257    o Added routines for passive tracer handling
258    o Added carbon sequestration sensitivity experiment
259    
260    checkpoint39
261     o Modifications and fixes to support TAMC
262       (mainly missing or wrong directives)
263     o Corrected common blocks when fooling TAMC to produce adjoint I/O
264       in addummy_in_stepping
265     o Updated verification/vero/ (bug fixes in code/, correct pickups in input/)
266     o Enabled "sliced" (xz-,yz-) exchanges, needed for obcs.
267     o Included following packages:
268       cal: calendar
269       exf: external forcing
270       ecco: essential routines to control use of cal, exf
271             (NB: this is not the full ECCO environment)
272     o disabled some packages by default in genmake
273    
274    checkpoint38
275     o see notes_c37_adj.txt
276     o corrected wrong layer index in external_forcing_t
277     o replaced the_main_loop/forward_step by the_main_loop

280     o added runtime flag for pre-C35 pickups: usePickupBeforeC35
281    
282    checkpoint37
283     o mdsio.F routine split and packaged in pkg/mdsio
284       (mdsio.F and mdsio_gl.F still exist in eesupp/src but are not
285        used unless genmake -disable=mdsio)
286     o allow a more precise surface-geopotential gradient for the atmosphere
287       taking into account the change in space of Alpha (=1/rho) at the surface.
288     o variable "etaN" (replace cg2d_x) is the surface R-anomaly [r unit]
289       (ocean: sea surface height [m] / atmos: surface pressure anomaly [Pa])
290     o Change units: Phi_Hydrostatic (=phiHyd), Phi_Surface(=cg2d_x) and
291       Phi_NonHydrostatic (=cg3d_x), all have now the dimension of a potential
292       [m2/s2] (pressure/rhoConst in the ocean ; Geo-Potential in the atmosphere).
293     o Time-Average diagnostics defined as a pseudo package "timeave".
294     o pickup files : old pickup (before c35) did not work with new code (c35
295       and after) unless activating 2 commented lines in initialise-varia.
296     o Non-Hydrostatic pickup file Pb fixed.
297     o bug with Rigid-lid version (since c35) fixed.  
298    
299    checkpoint36
300     o implement Crank-Nickelson barotropic time-stepping
301     o recover Time-Average diagnostics
302     o fix Pb in checkpoint (PR#19)
303     o AIM become a standard package ; clean unused CPP_kees
304    
305    checkpoint35
306     o subtantial rewrite of dynamics.f
307     o allows staggered time-stepping
308     o packaged obcs, aim (Atmospheric Physics), zonal_filt, shap_filt
309     o added bottom drag (linear + quadratic)
310    
311    checkpoint34
312     o Modified exchange routines for correct reverse simulation.
313     o Added verification output to comply with bug fix in impldiff.F
314       as of c33 (exp2, natl_box).
315     o Corrected store directives in dynamics.F
316     o Corrected array boundaries in impldiff.F
317     o Corrected array dimensions in gmredi.
318       Added temporary scalars to avoid storage by TAMC (gmredi, kpp).
319     o Added routine GLOBAL_SUM_INT to global_sum.F
320     o Added mdsio_gl.F for ECCO purposes.
321    
322    checkpoint33
323     o Fixed bug in lower BC in impldiff.F
324     o Fixed confusion about units of forcing arrays in FFIELDS.h
325       namely Fu,Fv,Qnet,Qsw,EmPmR:
326       - Removed verification/natl_box/code/external_fields_scale.F
327         (did not differ from that in model/src)
328       - Changed units of fu,fv,Qnet,Qsw,EmPmR back to proper units
329         (see FFIELDS.h for description)
330       - Scale fu,fv,Qnet,Qsw,EmPmR when used in external_forcing_surf.F,
331         kpp_calc.F and kpp_transport_t.F
332       - Removed model/src/external_fields_scale.F and calls to it
333       - verification/natl_box uses flux data with "atmospheric" sign so
334         a special version of external_fields_load.F is used to
335         change the data as it's read in. This way, the arrays
336         have the right units and signs at all times tha a user could
337         possibly use them.
338     o Corrected genmake to delete a temporary file during configuration
339    
340    checkpoint32
341     o Scaling of forcing fields moved from external_forcing.F to
342       external_fields_scale.F, called directly after loading fields.
343     o Surface relaxation terms added to surface tendency fields in
344       extra subroutine.
345     o impldiff.F changed to avoid storing by TAMC of huge intermediate
346       fields.
347     o Changes in GMRedi to comply with packaging structure.
348     o Modifications and bug fixes in KPP package.
349     o Verification experiment for KPP added (verification/nat_box/)
350    
351    checkpoint31
352     o Packages interface brought in line with defined standard
353       -> new routines packages_...F
354       -> changes in initialise_fixed.F, initialise_varia.F
355       -> enables initialisation interface for ECCO package
356     o Rescaling of external forcing fields immediately after read
357       (removed from external_forcing.F)
358       -> new: surface_fields_scale.F
359       -> affects ini_foorcing.F, external_fields_load.F
360     o Computation of surface tendencies before tendency updates.
361       -> new: external_forcing_surf.F
362     o Change of variable names useGMRedi, useKPP, useECCO
363     o Further changes in dynamics.F, impldiff.F for TAMC
364     o Tested for experiments 0, 2, 4.
365       - not yet tested for GMRedi.
366       - not yet tested for KPP.
367    
368    checkpoint30
369     o Updates for OBCs
370     o New experiment for test OBCs (internal_wave)
371     o New output.txt in verification/exp4/results/
372     o Updates for KPP: calculation of viscosity corrected, new variables

374     o CPP'd calls to system routines for TARGET_CRAY_VECTOR (P.H.)
375       and entry for T90 in genmake
376

379    
380    checkpoint28
381     o Corrected initialization of hFacMin for difference vertical coordinates
382     o Modified calculation of partial cell thickness to more robust algorithm
383     o config_summary.F: replaced write_1D_... by write_0D_...
384       read_write.F: added subroutines write_0D_...
385     o routines calc_common_factors, calc_gs, calc_gt, calc_phi_hyd, find_rho:
386       included some initialisations required for TAMC.
387     o routine calc_isoslopes: modified sqrt computation to make it
388       differentiable for zero argument.
389     o routines dynamics, impldiff:
390       included store directives and tape key computations required for TAMC.
391     o ALL TAMC related changes are between ifdef ALLOW_AUTODIFF_TAMC
392    
393    checkpoint27
394     o fixed calc_isoslopes() to so that cancellation of terms in tensor
395       formulation works properly with variable resolution.
396     o restructured the calling tree between the_model_main() and dynamics()
397     o split initialise() into initialise_fixed() and initialise_varia()

400    
401    checkpoint26

403       except the argument declarations. This was using up some memory.
404     o fixed macros like _ADT to work with both versions of Linux cpp
405     o cleaned up some unused and uninitialized variables
406       (helps when debugging with strict compile options)
407     o split up CPP_EEOPTIONS.h into options and macros
408       (macros are now in eesupp/inc/CPP_EEMACROS.h)
409     o patch for 2 processor JAM mode
410    
411    checkpoint25

416     o added a diagnostic of convective index
417     o moved call to calc_divg_hat() from dynamics() to solve_for_pressure()
