73    o Plus: Included switch ALLOW_AUTODIFF_MONITOR to handle
74      monitoring of adjoint state.

79      o additional storing needed for ustress,vstess
80        because of state-dependent quality check

82    o Plus: genmake with MAKEDEPEND variable was still missing in ecco-branch
83    NB: - verification/natl_box_adjoint/ 240 steps run
84          * looks ok under Linux (twain.lcs.mit.edu)
85          * looks ok on MIT SUN's (fjord.mit.edu)

101    o optim package: Added obcs control part for lsopt I/O
102      (by G. Gebbie)
103    o missing call to obcs_diags
104    o moved calls in packages_init_fixed to packages_readparms
105      because some quantities are needed earlier.
106    
107    ecco_c44_e20
108    o before major merges from the Scripps setup
109      here are two small updates:
110      - field swapping for surface flux controls enabled

156      All changes were merged in between (see ecco-branch-mod? tags).
157    o last changes:
158      * assuming path for TAF and TAMC are known (e.g. in $path)
159      * genmake:
160        - added tools/xmakedepend to circumvene shortcoming of
161          SUN's makedepend (size too small)

186    
187    ecco-branch-mod3
188    o this is the first part of changes necessary to reconcile

190      This set of changes is relevant for ECCO only.
191      The next set/tag of changes (ecco-branch-mod4)
192      should be merged into the main trunk.
193      - update some options

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

290      calc_diffusivity, calc_viscosity
291      (kpp_calc_diff, kpp_calc_visc).
292    o Added diffkr, kapgm to control variables
293    o bug fix in gmredi_slope_limit for ldd97
294    
295    checkpoint40pre5
296    o proper initialization of Adams-Bashforth time stepping
297      + uses forward step for very first step of model (iter=0)
298    o re-generated *all* output since almost all output is modified by this
299      change (sorry but we've been putting this one off for about 2 years)
300      + natl_box, aim.5l_Equatorial_Channel and aim.5l_zon-ave were
301        *not* regenerated since they are already out of date and I don't
302        want to create the impression that they are suddenly working.
303    o removed KAP stuff for DEC's
304    o modified/added many .cvsignore files in */code and */input
305    o added new expt "solid-body.cs-32x32x1"
306      + this uses an alternative form of ini_curvilinear_grid.F which
307        is not necessarily any better than the current one...
308    
309    checkpoint40pre4
310    o added re-initialisations of utrans,vtrans,rtrans in
311      calc_common_factors which are crucial for TAF.

323    o Updated to latest branch of AJA, JMC
324    o Added gradient check package
325    o Added routines for passive tracer handling
326    o Added carbon sequestration sensitivity experiment
327    
328    checkpoint39
329     o Modifications and fixes to support TAMC
330       (mainly missing or wrong directives)
331     o Corrected common blocks when fooling TAMC to produce adjoint I/O
332       in addummy_in_stepping
333     o Updated verification/vero/ (bug fixes in code/, correct pickups in input/)
334     o Enabled "sliced" (xz-,yz-) exchanges, needed for obcs.
335     o Included following packages:
336       cal: calendar
337       exf: external forcing
338       ecco: essential routines to control use of cal, exf
339             (NB: this is not the full ECCO environment)
340     o disabled some packages by default in genmake
341    
342    checkpoint38
343     o see notes_c37_adj.txt
344     o corrected wrong layer index in external_forcing_t
345     o replaced the_main_loop/forward_step by the_main_loop
346     o removed forceoutput from write_state
347       (replaced criteria for initial/final state)
348     o added runtime flag for pre-C35 pickups: usePickupBeforeC35
349    
350    checkpoint37
351     o mdsio.F routine split and packaged in pkg/mdsio
352       (mdsio.F and mdsio_gl.F still exist in eesupp/src but are not
353        used unless genmake -disable=mdsio)
354     o allow a more precise surface-geopotential gradient for the atmosphere
355       taking into account the change in space of Alpha (=1/rho) at the surface.
356     o variable "etaN" (replace cg2d_x) is the surface R-anomaly [r unit]
357       (ocean: sea surface height [m] / atmos: surface pressure anomaly [Pa])
358     o Change units: Phi_Hydrostatic (=phiHyd), Phi_Surface(=cg2d_x) and
359       Phi_NonHydrostatic (=cg3d_x), all have now the dimension of a potential
360       [m2/s2] (pressure/rhoConst in the ocean ; Geo-Potential in the atmosphere).
361     o Time-Average diagnostics defined as a pseudo package "timeave".
362     o pickup files : old pickup (before c35) did not work with new code (c35
363       and after) unless activating 2 commented lines in initialise-varia.
364     o Non-Hydrostatic pickup file Pb fixed.
365     o bug with Rigid-lid version (since c35) fixed.  
366    
367    checkpoint36
368     o implement Crank-Nickelson barotropic time-stepping
369     o recover Time-Average diagnostics
370     o fix Pb in checkpoint (PR#19)
371     o AIM become a standard package ; clean unused CPP_kees
372    
373    checkpoint35
374     o subtantial rewrite of dynamics.f
375     o allows staggered time-stepping
376     o packaged obcs, aim (Atmospheric Physics), zonal_filt, shap_filt
377     o added bottom drag (linear + quadratic)
378    
379    checkpoint34
380     o Modified exchange routines for correct reverse simulation.
381     o Added verification output to comply with bug fix in impldiff.F
382       as of c33 (exp2, natl_box).
383     o Corrected store directives in dynamics.F
384     o Corrected array boundaries in impldiff.F
385     o Corrected array dimensions in gmredi.
386       Added temporary scalars to avoid storage by TAMC (gmredi, kpp).
387     o Added routine GLOBAL_SUM_INT to global_sum.F
388     o Added mdsio_gl.F for ECCO purposes.
389    
390    checkpoint33
391     o Fixed bug in lower BC in impldiff.F
392     o Fixed confusion about units of forcing arrays in FFIELDS.h
393       namely Fu,Fv,Qnet,Qsw,EmPmR:
394       - Removed verification/natl_box/code/external_fields_scale.F
395         (did not differ from that in model/src)
396       - Changed units of fu,fv,Qnet,Qsw,EmPmR back to proper units
397         (see FFIELDS.h for description)
398       - Scale fu,fv,Qnet,Qsw,EmPmR when used in external_forcing_surf.F,
399         kpp_calc.F and kpp_transport_t.F
400       - Removed model/src/external_fields_scale.F and calls to it
401       - verification/natl_box uses flux data with "atmospheric" sign so
402         a special version of external_fields_load.F is used to
403         change the data as it's read in. This way, the arrays
404         have the right units and signs at all times tha a user could
405         possibly use them.
406     o Corrected genmake to delete a temporary file during configuration
407    
408  checkpoint32  checkpoint32
409   o Scaling of forcing fields moved from external_forcing.F to   o Scaling of forcing fields moved from external_forcing.F to
410     external_fields_scale.F, called directly after loading fields.     external_fields_scale.F, called directly after loading fields.
