145    o last changes:
146      * assuming path for TAF and TAMC are known (e.g. in $path)
147      * genmake:
148        - added tools/xmakedepend to circumvene shortcoming of
149          SUN's makedepend (size too small)

178      This set of changes is relevant for ECCO only.
179      The next set/tag of changes (ecco-branch-mod4)
180      should be merged into the main trunk.

252      mdsio_writetile - same as mdsio_writefield except works from inside
253                        bi,bj loop
254      mdsio_writelocal - same as mdsio_writetile except works for local
255                         arrays
256      write_local_r? - higher-level wrapper for mdsio_writelocal
257      Controlled by diagFreq. Defaults to zero (ie. no dumps)
258      Example given at end of mom_vecinv.F that dumps some local arrays.
259    o replaced calc_mom_rhs.F by mom_fluxform.F/mom_vecinc.F to

262      or genmake -DISABLE ...
263    o TAMC-related update to cope with mom_fluxform.F/mom_vecinc.F
264      (additional storing is now needed for case vecinv;
265      currently nothing implemented to switch this storing off
266      in case fluxform is used since no CPP flag available).

280    o Added diffkr, kapgm to control variables
281    o bug fix in gmredi_slope_limit for ldd97
282    
283    checkpoint40pre5
284    o proper initialization of Adams-Bashforth time stepping
285      + uses forward step for very first step of model (iter=0)
286    o re-generated *all* output since almost all output is modified by this
287      change (sorry but we've been putting this one off for about 2 years)
288      + natl_box, aim.5l_Equatorial_Channel and aim.5l_zon-ave were
289        *not* regenerated since they are already out of date and I don't
290        want to create the impression that they are suddenly working.
291    o removed KAP stuff for DEC's
292    o modified/added many .cvsignore files in */code and */input
293    o added new expt "solid-body.cs-32x32x1"
294      + this uses an alternative form of ini_curvilinear_grid.F which
295        is not necessarily any better than the current one...
296    
297    checkpoint40pre4
298    o added re-initialisations of utrans,vtrans,rtrans in
299      calc_common_factors which are crucial for TAF.

312    o Added gradient check package
313    o Added routines for passive tracer handling
314    o Added carbon sequestration sensitivity experiment
315    
316    checkpoint39
317     o Modifications and fixes to support TAMC
318       (mainly missing or wrong directives)
319     o Corrected common blocks when fooling TAMC to produce adjoint I/O
320       in addummy_in_stepping

328     o disabled some packages by default in genmake
329    
330    checkpoint38
331     o see notes_c37_adj.txt

336     o added runtime flag for pre-C35 pickups: usePickupBeforeC35
337    
338    checkpoint37
339     o mdsio.F routine split and packaged in pkg/mdsio
340       (mdsio.F and mdsio_gl.F still exist in eesupp/src but are not
341        used unless genmake -disable=mdsio)
342     o allow a more precise surface-geopotential gradient for the atmosphere
343       taking into account the change in space of Alpha (=1/rho) at the surface.
344     o variable "etaN" (replace cg2d_x) is the surface R-anomaly [r unit]
345       (ocean: sea surface height [m] / atmos: surface pressure anomaly [Pa])
346     o Change units: Phi_Hydrostatic (=phiHyd), Phi_Surface(=cg2d_x) and
347       Phi_NonHydrostatic (=cg3d_x), all have now the dimension of a potential
348       [m2/s2] (pressure/rhoConst in the ocean ; Geo-Potential in the atmosphere).
349     o Time-Average diagnostics defined as a pseudo package "timeave".
350     o pickup files : old pickup (before c35) did not work with new code (c35
351       and after) unless activating 2 commented lines in initialise-varia.
352     o Non-Hydrostatic pickup file Pb fixed.
353     o bug with Rigid-lid version (since c35) fixed.  
354    
355    checkpoint36
356     o implement Crank-Nickelson barotropic time-stepping
357     o recover Time-Average diagnostics
358     o fix Pb in checkpoint (PR#19)
359     o AIM become a standard package ; clean unused CPP_kees
360    
361    checkpoint35
362     o subtantial rewrite of dynamics.f
363     o allows staggered time-stepping
364     o packaged obcs, aim (Atmospheric Physics), zonal_filt, shap_filt
365     o added bottom drag (linear + quadratic)
366    
367    checkpoint34
368     o Modified exchange routines for correct reverse simulation.
369     o Added verification output to comply with bug fix in impldiff.F
370       as of c33 (exp2, natl_box).
371     o Corrected store directives in dynamics.F
372     o Corrected array boundaries in impldiff.F
373     o Corrected array dimensions in gmredi.
374       Added temporary scalars to avoid storage by TAMC (gmredi, kpp).
375     o Added routine GLOBAL_SUM_INT to global_sum.F
376     o Added mdsio_gl.F for ECCO purposes.
377    
378    checkpoint33
379     o Fixed bug in lower BC in impldiff.F
380     o Fixed confusion about units of forcing arrays in FFIELDS.h
381       namely Fu,Fv,Qnet,Qsw,EmPmR:
382       - Removed verification/natl_box/code/external_fields_scale.F
383         (did not differ from that in model/src)
384       - Changed units of fu,fv,Qnet,Qsw,EmPmR back to proper units
385         (see FFIELDS.h for description)
386       - Scale fu,fv,Qnet,Qsw,EmPmR when used in external_forcing_surf.F,
387         kpp_calc.F and kpp_transport_t.F
388       - Removed model/src/external_fields_scale.F and calls to it
389       - verification/natl_box uses flux data with "atmospheric" sign so
390         a special version of external_fields_load.F is used to
391         change the data as it's read in. This way, the arrays
392         have the right units and signs at all times tha a user could
393         possibly use them.
394     o Corrected genmake to delete a temporary file during configuration
395    
396  checkpoint32  checkpoint32
397   o Scaling of forcing fields moved from external_forcing.F to   o Scaling of forcing fields moved from external_forcing.F to
398     external_fields_scale.F, called directly after loading fields.     external_fields_scale.F, called directly after loading fields.
