89      This set of changes is relevant for ECCO only.
90      The next set/tag of changes (ecco-branch-mod4)
91      should be merged into the main trunk.
92      - update some options

158    o added multi-dimensional advection method for tracers
159      
160    checkpoint40pre8
161    o new package rw/
162      Added method for dumping intermediate local arrays:
163      mdsio_writetile - same as mdsio_writefield except works from inside
164                        bi,bj loop
165      mdsio_writelocal - same as mdsio_writetile except works for local
166                         arrays
167      write_local_r? - higher-level wrapper for mdsio_writelocal
168      Controlled by diagFreq. Defaults to zero (ie. no dumps)
169      Example given at end of mom_vecinv.F that dumps some local arrays.
170    o replaced calc_mom_rhs.F by mom_fluxform.F/mom_vecinc.F to

173      or genmake -DISABLE ...
174    o TAMC-related update to cope with mom_fluxform.F/mom_vecinc.F
175      (additional storing is now needed for case vecinv;
176      currently nothing implemented to switch this storing off
177      in case fluxform is used since no CPP flag available).
178    
179    checkpoint40pre7

191    o Added diffkr, kapgm to control variables
192    o bug fix in gmredi_slope_limit for ldd97
193    
194    checkpoint40pre5
195    o proper initialization of Adams-Bashforth time stepping
196      + uses forward step for very first step of model (iter=0)
197    o re-generated *all* output since almost all output is modified by this
198      change (sorry but we've been putting this one off for about 2 years)
199      + natl_box, aim.5l_Equatorial_Channel and aim.5l_zon-ave were
200        *not* regenerated since they are already out of date and I don't
201        want to create the impression that they are suddenly working.
202    o removed KAP stuff for DEC's
203    o modified/added many .cvsignore files in */code and */input
204    o added new expt "solid-body.cs-32x32x1"
205      + this uses an alternative form of ini_curvilinear_grid.F which
206        is not necessarily any better than the current one...
207    
208    checkpoint40pre4
209    o added re-initialisations of utrans,vtrans,rtrans in
210      calc_common_factors which are crucial for TAF.

225    o Added carbon sequestration sensitivity experiment
226    
227    checkpoint39
228     o Modifications and fixes to support TAMC
229       (mainly missing or wrong directives)
230     o Corrected common blocks when fooling TAMC to produce adjoint I/O
231       in addummy_in_stepping

234     o Included following packages:
235       cal: calendar
236       exf: external forcing
237       ecco: essential routines to control use of cal, exf
238             (NB: this is not the full ECCO environment)
239     o disabled some packages by default in genmake
240    
241    checkpoint38
242     o see notes_c37_adj.txt
243     o corrected wrong layer index in external_forcing_t
244     o replaced the_main_loop/forward_step by the_main_loop
245     o removed forceoutput from write_state
246       (replaced criteria for initial/final state)
247     o added runtime flag for pre-C35 pickups: usePickupBeforeC35
248    
249    checkpoint37
250     o mdsio.F routine split and packaged in pkg/mdsio
251       (mdsio.F and mdsio_gl.F still exist in eesupp/src but are not
252        used unless genmake -disable=mdsio)
253     o allow a more precise surface-geopotential gradient for the atmosphere
254       taking into account the change in space of Alpha (=1/rho) at the surface.
255     o variable "etaN" (replace cg2d_x) is the surface R-anomaly [r unit]
256       (ocean: sea surface height [m] / atmos: surface pressure anomaly [Pa])
257     o Change units: Phi_Hydrostatic (=phiHyd), Phi_Surface(=cg2d_x) and
258       Phi_NonHydrostatic (=cg3d_x), all have now the dimension of a potential
259       [m2/s2] (pressure/rhoConst in the ocean ; Geo-Potential in the atmosphere).
260     o Time-Average diagnostics defined as a pseudo package "timeave".
261     o pickup files : old pickup (before c35) did not work with new code (c35
262       and after) unless activating 2 commented lines in initialise-varia.
263     o Non-Hydrostatic pickup file Pb fixed.
264     o bug with Rigid-lid version (since c35) fixed.  
265    
266    checkpoint36
267     o implement Crank-Nickelson barotropic time-stepping
268     o recover Time-Average diagnostics
269     o fix Pb in checkpoint (PR#19)
270     o AIM become a standard package ; clean unused CPP_kees
271    
272    checkpoint35
273     o subtantial rewrite of dynamics.f
274     o allows staggered time-stepping
275     o packaged obcs, aim (Atmospheric Physics), zonal_filt, shap_filt
276     o added bottom drag (linear + quadratic)
277    
278    checkpoint34
279     o Modified exchange routines for correct reverse simulation.
280     o Added verification output to comply with bug fix in impldiff.F
281       as of c33 (exp2, natl_box).
282     o Corrected store directives in dynamics.F
283     o Corrected array boundaries in impldiff.F
284     o Corrected array dimensions in gmredi.
285       Added temporary scalars to avoid storage by TAMC (gmredi, kpp).
286     o Added routine GLOBAL_SUM_INT to global_sum.F
287     o Added mdsio_gl.F for ECCO purposes.
288    
289    checkpoint33
290     o Fixed bug in lower BC in impldiff.F
291     o Fixed confusion about units of forcing arrays in FFIELDS.h
292       namely Fu,Fv,Qnet,Qsw,EmPmR:
293       - Removed verification/natl_box/code/external_fields_scale.F
294         (did not differ from that in model/src)
295       - Changed units of fu,fv,Qnet,Qsw,EmPmR back to proper units
296         (see FFIELDS.h for description)
297       - Scale fu,fv,Qnet,Qsw,EmPmR when used in external_forcing_surf.F,
298         kpp_calc.F and kpp_transport_t.F
299       - Removed model/src/external_fields_scale.F and calls to it
300       - verification/natl_box uses flux data with "atmospheric" sign so
301         a special version of external_fields_load.F is used to
302         change the data as it's read in. This way, the arrays
303         have the right units and signs at all times tha a user could
304         possibly use them.
305     o Corrected genmake to delete a temporary file during configuration
306    
307    checkpoint32
308     o Scaling of forcing fields moved from external_forcing.F to
309       external_fields_scale.F, called directly after loading fields.

311       extra subroutine.
312     o impldiff.F changed to avoid storing by TAMC of huge intermediate
313       fields.
314     o Changes in GMRedi to comply with packaging structure.
315     o Modifications and bug fixes in KPP package.
316     o Verification experiment for KPP added (verification/nat_box/)
317    
318    checkpoint31
319     o Packages interface brought in line with defined standard
320       -> new routines packages_...F
321       -> changes in initialise_fixed.F, initialise_varia.F
322       -> enables initialisation interface for ECCO package
323     o Rescaling of external forcing fields immediately after read
324       (removed from external_forcing.F)
325       -> new: surface_fields_scale.F
326       -> affects ini_foorcing.F, external_fields_load.F
327     o Computation of surface tendencies before tendency updates.
328       -> new: external_forcing_surf.F
329     o Change of variable names useGMRedi, useKPP, useECCO
330     o Further changes in dynamics.F, impldiff.F for TAMC
331     o Tested for experiments 0, 2, 4.
332       - not yet tested for GMRedi.
333       - not yet tested for KPP.
334    
335    checkpoint30
336     o Updates for OBCs
337     o New experiment for test OBCs (internal_wave)
338     o New output.txt in verification/exp4/results/
339     o Updates for KPP: calculation of viscosity corrected, new variables
340       kpp_dumpFreq and kpp_taveFreq
341     o CPP'd calls to system routines for TARGET_CRAY_VECTOR (P.H.)
342       and entry for T90 in genmake
343    
344    checkpoint29
345     o packaged KPP and GM/Redi
346    
347    checkpoint28
348     o Corrected initialization of hFacMin for difference vertical coordinates
349     o Modified calculation of partial cell thickness to more robust algorithm
350     o config_summary.F: replaced write_1D_... by write_0D_...
351       read_write.F: added subroutines write_0D_...
352     o routines calc_common_factors, calc_gs, calc_gt, calc_phi_hyd, find_rho:
353       included some initialisations required for TAMC.
354     o routine calc_isoslopes: modified sqrt computation to make it
355       differentiable for zero argument.
356     o routines dynamics, impldiff:
357       included store directives and tape key computations required for TAMC.
358     o ALL TAMC related changes are between ifdef ALLOW_AUTODIFF_TAMC
359    
360  checkpoint27  checkpoint27
361   o fixed calc_isoslopes() to so that cancellation of terms in tensor   o fixed calc_isoslopes() to so that cancellation of terms in tensor
