6    
7    checkpoint57s_post
8    o Add clearing-house for viscosity calculations, mom_calc_visc and
9      correct numerous bugs in LeithD and Smagorinsky discretizations.  
10      mom_calc_visc now allows for Smagorinsky, Leith and LeithD to be
11      used simultaneously, and to be used in mom_vecinv and mom_fluxform.
12      Mom_vecinv can be used with standard viscous calculation (mom_vi_hdissip.F)
13      and with Strain-Tension viscous term calculation (mom_hdissip.F).  
14      The Strain-Tension form is now called with useStrainTensonVisc=.true.
15      ViscAhStrain and viscAhTension are now retired.
16    o diagnostics "VISCAHD" & "VISCA4D" replace "VISCAH" & "VISCA4".
17    o In response to JMC's bug report, genmake2 now ignores any soft-links
18      that it finds in the *current* directory when searching for files.
19      Soft-links found in any other source directories will still work as
20      they did before.
21    o add HAVE_SETRLSTK define and useSETRLSTK flag (eedata) which calls
22      a C routine to unlimit the stack size
23    o mnc-ify pkg/aim snapshot vars
24    o mnc-ify pkg/land as requested by Daniel
25    o various changes to mnc including:
26      - all files use the new "BASENAME[[.ITER].{t|f}NUM].nc" format
27      - output can now be grouped so that all files within a group
28          change the ITER portion of their names in lock-step together
29      - can now read ("global") PER-FACE (in addition to PER-TILE) files
30          and works with both EXCH1 and EXCH2 (but needs more testing)
31      - writing works for all verification test cases w/ g77 on Linux
32    
33    checkpoint57r_post
34    o make MNC variable initialization happen earlier
35    o add diagnostics for (almost) each term of the momentum Eq.
36    o remove SST,SSS,UVEL_k2,VVEL_k2 diagnostics.
37    o move pkg timeave out of pkg-groups "oceanic" & "atmospheric" (pkg/pkg_groups)
38    o remove MINIMAL_TAVE_OUTPUT option ;
39      add "dumpInitAndLast" to replace "nodumps" (and MINIMAL_TAVE_OUTPUT).
40    o move some basic S/R (used elsewhere in the code) from pkg/mdsio to eesupp/src
41      allows to compile without pkg/mdsio (& test successfully hs94.1x64x5)
42    o add MNC output for adjoint of EXF (adexf), SEAICE (adseaice)
43    o add time-dependent SST, SSS control
44    o cost terms in ecco/ modularized (new cost_generic.F)
45    o cost_averages routines are modularized (new cost_averagesgeneric.F)
46    o new infrastructure for seaice model vs. obs misfits in seaice/
47      * driver from the_main_loop.F is seaice_cost_driver.F
48      * first term is AREA vs. SMR observation misfit (ALLOW_SEAICE_COST_SMR_AREA)
49      * gradient check in Exp. 6a of natl_box_adjoint/
50    o natl_box_adjoint input_seaice for Lab. Sea now available online via wget
51      (see README file)
52    
53    checkpoint57q_post
54    o fix initialisation Pb in calc_gw (get NANs in exp5 with g77)
55    o fix annoying months-old bug in mnc/mdsio output for seaice pkg
56      - bug was reported by Jean-Michel and Ian Fenty
57    o fix initialization Pb in AIM-Ocean coupled model (aim_sice2aim.F)
58      update exp. cpl_aim+ocn output.
59    o Implement 4-level checkpointing: AUTODIFF_4_LEVEL_CHECKPOINT
60      Needed for high-res. runs with large global files
61      to be able to limit tapelev size
62    o Changed some tests for adjoint:
63      * carbon/ now tests AUTODIFF_2_LEVEL_CHECKPOINT
64      * natl_box_adjoint/code_bulk/ tests AUTODIFF_4_LEVEL_CHECKPOINT
65      * global_ocean.90x40x15/ back to default 3-level checkpointing
66    o Modifications to enable scripted COMMON to MODULE conversion
67      * verification/OpenAD/code/ has necessary scripts and description;
68      * converts, compiles and runs successfully;
69    
70    checkpoint57p_post
71    o reading of delXfile & delYfile moved from ini_parms.F to ini_grid.F
72    o move ${PKG}_MNC_INIT from ${PKG}_READ_PARAMS to ${PKG}_INIT_FIXED
73      (already the case for some pkgs, including recent MNC_init, e.g. thsice)
74    o call CALC_GW from DYNAMICS (instead of from FORWARD_STEP)
75    o Dissipation & phiHyd gradient are always added to gU,gV in timestep.F
76      (was already the case for dissipation with mom_vecinv,
77       and also the case for grad.PhiHyd when staggered-timeStep)
78      This will allow to put dissipation out-off the AB time-stepping.
79     Unfortunately, affects truncation error. Update output of exp. that "fails"
80      (cg2d matching number) and leave the others for later: front_relax(10),
81      global_ocean_pressure(10),ideal_2D_oce(10),internal_wave(9),lab_sea(12),
82      matrix_example(7!),natl_box(12),plume_on_slope(11),vermix(12x3,11x2).
83    
84    checkpoint57o_post
85    o fix MNC/MDSIO flags in PTRACERS so that (1) it works, and
86      (2) its ready to be documented during the 20050801 DocFest
87    o MNC-ify the gmredi package -- tested and works w/ and w/o mnc
88      for ideal_2D_oce and lab_sea on linux_ia32_g77
89    o set to #undef CTRL_SET_OLD_MAXCVARS_30
90      in global1x1_tot/code_seaice_adj to access indices 32, 33
91      (worth another tag)
92    
93    checkpoint57n_post
94    o adding precip control xx_precip 32
95    o adding swflux control xx_swflux 33
96    o Replacing 10 forcing penalty cost routines by 1 generic.
97    o Implementing partitioning in time-mean and variable adjustment
98      for atmos. state.
99    o Time-mean constant error is now read in data.ecco (instead of hard-coded)
100    o in natl_box_adjoint:
101      * updated exp 1 to 10
102        (but does not have time-mean vs. variable split results yet)
103    o updated global1x1/*_seaice_adj/
104      to incorporate latest changes
105    o enable useSingleCpuIO for mdsio vector routines
106      (applies in particular to tapelev I/O)
107    o removed inefficient K-loop in all active_file*control*.F
108    
109    checkpoint57m_post
110    o re-arrange exp. adjustment.cs-32x32x1 (adjust_nlfs.cs-32x32x1 merge into)
111      and advect_cs (use EXCH-2 and standard cs-32 grid files).
112    o pkg/exch2: filling of face-corner halo regions is optional
113      (ifdef W2_FILL_NULL_REGIONS) and is turned off by default.
114    
115    checkpoint57l_post
116     tag before updating tutorials (pre-release-2)
117    o add cos & sin of grid-direction orientation angle (curvilinear grid only,
118       for output and interpolation of input fields onto model grid)
119    o fix radius in mom_v_metric_cylinder.F (wrong by dy/2).
120       Affects results of exp. rotating_tank ; update output.txt.
121    o pkg/diagnostics: 2 new S/R to fill a diagnostics using a scaling factor
122          and taking the square quantity and/or using a fraction-weight field.
123    o fix aim_diagnostics_init.F mate numbers.
124    o add mnc output capability to diagnostics/diagstat and update
125      our cvsignore files for the ACSII output generated
126    
127    checkpoint57k_post
128    o lab_sea now uses diagnostics package and provides a suite of
129      new EXF diagnostics output.
130    
131    checkpoint57j_post
132    o exf
133      * bug fix in exf_bulkformulae for psimh (spotted by Eliyahu Biton):
134        Bracket missing in eqn. for psimh (eqn. 7 of Large & Pond, 1982);
135        terms -2*ATAN(x) + pi/2 were added to both stable and unstable case.
136      * extended diagnostics output
137        - now includes all EXF variables
138        - hs, hl moved to common block
139        - separate S/R for diagnostics, called after ctrl vector is added
140        - name changed for EXFsw -> EXFswnet, EXFlw -> EXFlwnet
141        - EXFqnet contains true Qnet (i.e. includes qsw)
142      * updated verif. lab_sea, global_with_exf
143      * Rearranging hflux (exf_mapfields -> exf_getforcing)
144        to ensure that diagnostics sees a true EXFqnet
145    o add matlab scripts for CS-grid vectors (in utils/cs_grid)
146    o diagnostics pkg: change pointers so that 1 diagnostic can be used
147      several times with different frequencies.
148    o mnc-ify the thsice package as requested by Daniel Enderton
149      - the monitor--MNC output needs work
150      - many attributes need to be added (most are currently blank)
151    o mnc-ify theaim_v23 package as requested by Daniel Enderton
152      - many attributes need to be added (most are currently blank)
153    o remove "groundAtK1" & "rkFac" (replaced by usingPCoords & -rkSign)
154    o add Sadourny like discretization to the 4th.O vorticity advection scheme
155    o fix bug in rStar code (calc_r_star.F) when used with topo/bathy.
156      update output.txt from: aim.5l_cs (& .thSI), cpl_aim+ocn,
157         fizhi-gridalt-hs and global_ocean.cs32x15 (& .thsice).
158    o fix few little things to avoid floating error with -ftrapuv (ifort v9)
159     (ini_spherical_polar_grid.F, calc_r_star.F, monitor/mon_surfcor.F)
160    
161    checkpoint57i_post
162    o Diagnostics package was changed: diagnostic allocation is now deactivated
163      by setting an empty file name in the namelist (used to be by setting 0 frequency)
164    o momentum advection (VI form) options: activate 4th.O vorticity Coriolis ;
165      add 1rst Order upwind vertical Shear.
166    o add a quick fix for A/B checkpointing in OFFLINE mode
167    o add IGNORE_TIME define and -ignore_time option to genmake2 as an
168      end-run around the C/Fortran linking horror in eesup/src/timers.F
169    o added pkg/runclock: allows user to terminate run based on wall clock
170    o added non-hydrostatic scaling parameter: nh_am2
171    o pkg/my82: futile attempt to make results compiler-independent by adding
172      some "_d 0", etc. no effect.
173    o for mnc output, fill the 'T' coordinate var with myTime and create a
174      separate 'iter' variable for iteration count
175    o pkg/diagnostics:
176      add new capability: output of Global/Regional & per-level statistics ;
177      tested against monitor output (including land & thSIce) on various exp.
178    o make seaice-pkg I/O type flags (MNC/MDS) more standard.
179    
180    checkpoint57h_done
181      tag after changing user customized files (DIAGNOSTICS_SIZE.h,
182      data.diagnostics, data.gchem, data.ptracers) is done.
183    
184    o pkg/diagnostics: prepare for Global/Regional statistics.
185      add 2nd namelist in data.diagnostics and update DIAGNOSTICS_SIZE.h
186    o remove "baseTime" (no used) from arg. list of DIFF_BASE_MULTIPLE
187      and rename it: DIFFERENT_MULTIPLE
188    
189    checkpoint57h_post
190    o move tIter0 from data.gchem to PTRACERS_Iter0 in data.ptracers
191    o pkg/diagnostics: change output frequency, now in seconds (instead
192      of Nb of iterations). This requires to change data.diagnostics.
193    checkpoint57h_pre
194    
195    o in mnc, let the user create the output dir if both mnc_outdir_date
196      and mnc_outdir_num are false
197    o add fflags() to pkg/diagnostics which allows one to specify, on a
198      per-file basis, the file precision [default behavior is unchanged]
199    o added diagnostics to pkg/kpp, including computation of mixed layer
200      depth based on a temperature/density criterion
201    o updated verification/natl_box to test the new pkg/kpp diagnostics
202    o bugs fixed (with useAbsVorticity=T & with useJamartMomAdv=T)
203    o test AB-3 code with 4th.Order advection scheme (advect_xy/input.ab3_c4)
204    o fix mnc flags in pkg/seaice so that they are "owned" by seaice,
205      not mnc -- this mistake was found by JMC and is now corrected
206    
207    checkpoint57g_post
208    o add Adams-Bashforth 3rd Order time stepping:
209      - default remains AB-2 (#undef ALLOW_ADAMSBASHFORTH_3)
210      - not yet implemented with NH, CD_Scheme, pTracers, MNC_pickup ...
211    checkpoint57g_pre
212    
213    o make lambda[Theta,Salt]ClimRelax spatially varying
214      (default remains spatially uniform constant based on tau)
215    o added new control variables
216      * init. uVel, vVel, etanN
217      * lambda[Theta,Salt]ClimRelax
218    o separate masks used for ctrl_pack/unpack 'from write_grid' output
219      (suggested by G. Forget)
220    
221    checkpoint57f_post
222    o add parameter "baseTime" = model base time = time at iteration zero
223      new function DIFF_BASE_MULTIPLE (replace DIFFERENT_MULTIPLE) to
224      account for baseTime shift
225    o move Coriolis arrays from PARAMS.h to GRID.h
226    checkpoint57f_pre
227    
228    o mnc-ifying the seaice package
229    o introduced an alternative length scale calculation for use in the limiting
230      maximum viscosity (off by default, see mom_vi_hdissip.F for details)
231    o S/R ptracers_calc_diff: argument list bug for CALL KPP_CALC_DIFF_S
232    o added modified Leith scheme with viscosity proportional to grad(Hdiv)
233      as well as grad(vort3).  Made it compatible with both approximate form
234      for the cubed sphere and full form of these gradients.  Added flag
235      useFullLeith to select between approximate and full form.  
236    o add "d0" in getcon.F to reduce differences between compilers/platforms
237      update output.txt of exp. fizhi-gridalt-hs
238    o change port_rand funtion to allow to set the seed.
239    o fix obscure MNC bug involving conversion between reals and integers
240      - it caused no problems with certain (eg. gcc, ifc) compilers but the
241        new version is now more standards-compliant
242    o adjoint-related modifications
243      * gad_dst3_adv_?: to be able to use advscheme=30 in adjoint
244      * gad_calc_rhs: fool adjoint, revert to advscheme=30 in reverse when using 33
245      * mom_vi_hdissip: to be able to use Leith scheme in adjoint
246    
247    checkpoint57e_post
248    o Adding eddy stress controls a la Ferreira et al.
249    checkpoint57e_pre (actually was tagged: eckpoint57e_pre)
250    
251    o fizhi pkg: fix AtoC and CtoA when called with same input & output array
252      update output.txt of exp. fizhi-gridalt-hs
253    o add more "Z" dimensions and associated coordinate vars to MNC
254    o pkg/exf: added twoDigitYear capability for option useExfYearlyFields
255    o parameter calendarDumps: when set, approximate months (30-31 days) and years
256      (360-372 days) for parameters chkPtFreq, pChkPtFreq, taveFreq, SEAICE_taveFreq,
257      KPP_taveFreq, and freq in pkg/diagnostics are converted to exact calendar
258      months and years.  Requires pkg/cal.
259    o diagnostics: add pickup functionality
260      - off by default for backwards compatibility
261      - current version only uses MDSIO -- MNC will be added
262    o allow to use pkg diagnostics for LAND pkg output & Shapiro Tendencies.
263    o pkg/shap_filt: fix for multi-tiles per face (CS-grid with EXCH2)
264    
265    checkpoint57d_post
266    o pkg/thsice used in the ocean: fix tile Pb related to sIceLoad forcing
267    o modify verification/ideal_2D_oce so that it tests the creation of mnc
268      output from the diagnostics package
269    o temporary fix in EXCH2_UV: add a 3rd call to fix the 24.tiles CS-grid set-up
270    o make genmake2 more portable by using ".$FS" instead of ".f" for more
271      of the test compilations (eg. IBM xlf on Mac OSX w/HFS filesys)
272    o add coordinate variables to the MNC output from the diagnostics package
273    o change MNC-flags default value: true when useMNC=TRUE
274    o add a "readgrid_mnc" flag to MNC and give model/src/ini_curvilinear_grid.F
275      the ability (off by default) to read the grid information using MNC
276    o lab_sea: use LSR_ERROR=1.E-12 for testing ; update output.txt
277    o diagnostics: fix a bug (sub-set of levels); keep full precision when averaging
278    o do snap-shot diagnostics at the middle of the time-interval (instead of
279      at the end).
280    o update exp. aim.5l_cs (use default LAND_OPTIONS.h file) and add
281      new test for AIM with thSIce + slab-ocean
282    o cpl_aim+ocn test: update output (optfile & default GMREDI_OPTIONS.h)
283    o move state variable diagnostics to the beginning of the time step ;
284      (note: still needs some work specially for snap-shot diagnostics)
285      duplicate & replace UVELVVEL diagnostics with UV_VEL_C & UV_VEL_Z
286    
287    checkpoint57c_post
288    o Change testing option (-ieee) to get closer agreement between g77 & ifort
289    o generate new output.txt files on faulks with g77 & the new -ieee option
290    checkpoint57c_pre
291    
292    o add "_d 0" in freeze ; change some "FLOAT" to "DFLOAT" and went back (TAF);
293      update output.txt of exp. global_ocean.90x40x15
294    o fix in ini_eos.F (one "_d 0" was missing): now g77 & ifc give much closer
295      results; update global_ocean_pressure & global_ocean.cs32x15 output.txt
296    o add saltFlux(+File) forcing capability with periodicExternalForcing
297    o allow to use pkg diagnostics for GM-Redi & ThSIce output
298    o diagnostics_fill: fill in up to sNx+1 or sNy+1 (if U,V or Z pt) for mnc.
299    o improvements for the MNC output from DIAGNOSTICS:
300      - correct handling of the unlimitied dimension
301      - all dims now have associated coordinate variables
302      - variables located at U, V, and Corner ("Z") points are now written
303        with the correct horzontal dimensions (eg. 'Xp1', 'Yp1') so that
304        *all* data points are output
305    o added seaice_summary.F and removed obsolete ALLOW_SEAICE's from pkg/seaice
306    o added pkg/seaice/seaice_monitor.F
307    o mdsio_readfield.F can now read files visible only to master MPI process.
308    o pkg/seaice: some test code for ice-modified ocean stress
309    o exf_getffields interpolation defaults to bilinear for all scalar forcing
310      fields (remains bicubic for wind velocity and stress).  This avoids, e.g.,
311      spurious negative numbers for precipitation and humidity.  Will cause
312      some small numerical differences for integrations using pkg/exf/exf_interp.F.
313    o pkg/ctrl/
314      * Add ctrlvec diagnostics in pack/unpack for nondimensional I/O
315        May be enabled via doPackDiag
316      *  introduce z-scaling of
317         + gradient (doZscalePack) and
318         + control (doZscaleUnpack)
319    o pkg/mdsio/
320      * enable useSingleCpuIO for state estimation (ctrl_pack/unpack) mdsio_gl.F
321      * N.B.: leave tiled I/O for tapelev (i.e. mds...vector)
322    
323    checkpoint57b_post
324    o simplify options in diagnostics_fill arguments (remove weird combinations)
325    o fix MNC coordinate variables so that they now contain per-face index
326      values (instead of xC,xG,yC,yG values) when run with EXCH2 since, in
327      general, EXCH2 grids are only aligned to a "local" coordinate system
328    o test diagnostics pkg in dic_example (no output) and ideal_2D_oce (with ouput)
329    o Implement instantaneous output within pkg diagnostics:
330      setting a negative frequency in data.diagnostics produces
331     "snap-shot" output (as opposed to time-average if freq > 0)
332    o move out off EQUIVALENCE all diagnostics that fizhi does not use ;
333      NOTE: change ptracer diagnostics name: use 2 characters to work with
334            more than 9 tracers. Add also diagnostics of advect & diffus flux.
335    o more CF compliance: convert all MNC 'iter' variables to 'T' so that it
336      becomes the coordinate variable for the 'T' dimension
337    o add CF-style coordinate variables to MNC
338      - just a first cut:  numbers are meaningless on the cubesphere and
339        missing along the T axis but otherwise it works!
340    o add surface flux diagnostics: TAUX, TAUY, TFLUX, TRELAX, TICE, SFLUX, SRELAX
341    o pkg/thSIce: read initial state from 6 files ; allow monitor to use MNC.
342    o add diagnostics of advective & diffusive flux for T & S (pTracers coming soon)
343      this is based directly on what the model compute, so that the content of
344      each diagnostics might be affected by switching options (e.g., implicitDiffusion)
345    o small changes for diagnostics (gad_biharm_?.F, arguments of S/R impldiff.F)
346    o clean up build options files for SunOS, in particular
347      - remove -traditional from xmakedepend
348      - change -xarch=v9 to -xarch=native for f77
349      - restore use of make (not gmake)
350      - add CC=gcc if using g77
351    o changes per discussion of AM, JMC, & EH3 today:
352      - move redundant "grid" variables out of "state" -- in preparation of
353        creating proper CF-style coordinate variables and in recognition
354        that any/all grid variables can be easily copied (eg. w/NCO) from
355        the grid files into any of the other NetCDF files
356      - *always* output grid variables with MDSIO (this will eventually be
357        changed)
358      - output MNC grid file if useMNC is true
359    o every instance of _END_MASTER() has been found and replaced with
360      _END_MASTER( myThid ) in order to satisfy certain picky Sun
361      preprocessors
362    o re-arrange diagnostics pkg initialisation:
363     - allow each package to extend the available diagnostics list
364     - add some checking and fix small problems (multi-threaded, ...)
365     - new S/R diagnostics_fill (replace fill_diagnostics):
366       look through the short list of active diag. (instead of the long list)
367       create function DIAGNOSTICS_IS_ON to tell if a diagnostics is active
368    
369    checkpoint57a_post
370    o this set of changes restores TAMC compatibility
371      tested for global_ocean.90x40x15 adjoint on trough
372      (what a pain)
373    
374    checkpoint57a_pre
375    o some modifs in tools/build_options for sunos
376    o call ctrl_pack for ctrl at end for optimcycle=0
377    
378    checkpoint57
379    o add horizontal bi-harmonic viscosity for vertical velocity
380      - new parameter viscA4W (defaults to viscA4)
381      - affects only non-hydrostatic code
382      - to be done: no-slip lateral boundary conditions
383    o switch back to "sflux = sflux - runoff" in exf_getforcing.F
384    o implement Implicit Vertical advection for pTracers
385    o depth convergence accelerator: replace deltaTtracer by dTtracerLev(k)
386      (implemented also for implicit vertical diffusion & advection)
387    o OBCS: extend application of tracer open boundary conditions
388      to a strip beyond the boundary of width Olx/Oly
389    o add call monitor to TAF set of required calls (flow directives)
390      and include in natl_box_adjoint
391    o untangle a few ifdefs related to cost, ctrl, autodiff
392      untangel a few ALLOW_ECCO_OPTIMIZATION
393    o Apply Cooper & Haines representative estimates also at sub-surface (k=Nr)
394      (theta2, salt2 in ecco_cost_weights)
395    
396    checkpoint56c_post
397    o OBCS as control variables
398      - update ctrl_ad_diff.list, obcs_ad_diff.list
399      - remove balance of obcs controls from default
400      - fix index bug nobcs in ctrl_init
401      - fix dummy fields filen in ctrl_pack
402      - add dummy weights for obcs
403    o lsopt: comment out fort.94 output
404    o optim:
405      - remove unnecessary header files
406      - adjusted namelists
407      - add xerbla.F to Makefile
408    o exf:
409      - multiple modifications of exf_check_range
410      - unit change in exf_init_runoff from [m/year] to [m/s]
411    o mdsio:
412      - i/o-vector change debugLevel from debLevA to debLevB
413    
414    checkpoint56b_post
415    o collect all ptracers output in an new routine (PTRACERS_OUTPUT) that
416      is called from DO_THE_MODEL_IO
417      - rename PTRACERS_STATV_WRITE to PTRACERS_WRITE_TIMEAVE
418      - introduce new parameter PTRACERS_dumpFreq (defaults to dumpFreq)
419      - clean up PTRACERS_WRITE_TIMEAVE a little
420    o add another verification experiment that tests both the cfc-pkg and
421      the gchem-pkg with GCHEM_SEPARATE_FORCING undefined, that is with
422      reactive tendencies treated inline with regular timestepping
423    o testreport previously did a lousy job of comparing small numbers, so
424      we (Ed and Martin) changed the  way the cut-off of 1.e-12 is
425      implemented in the little c-progam tmp_cmpnum.c which is embedded in
426      testreport.
427    o ptracers_monitor: bug fix for MPI
428    
429    checkpoint56a_post
430    o GCHEM: finish reorganizating the package
431      - forward_step calls GCHEM_CALC_TENDENDY, which computes gchemTendency
432        (introduces another 3D-array for each passive tracer, but only if
433        GCHEM_SEPARATE_FORCING is undefined. For GCHEM_SEPARATE_FORCING
434        gchemTendency is not needed because the timestep is done separately)
435      - gchemTendency is added to gPtr in GCHEM_ADD_TENDENCY
436      - GCHEM is now---more or less cleanly---separate from PTRACERS
437      - to bo done: handling of surfaceForcingPtr that is needed for KPP not
438        so clear to me how that should be done in a general way.
439    o CFC: improve formatting of output in CFC_ATMOS
440    o PTRACERS:
441      - rename GCHEM_MONITOR to PTRACERS_MONITOR and call it from MONITOR, so
442        that ALL experiments with ptracers enable can be checked. This makes
443        GCHEM_MONITOR obsolete.
444      - include a runtime parameter PTRACERS_monitorFreq that defaults to
445        monitorFreq
446      - set default PTRACERS_write_mdsio to false if PTRACERS_write_mnc is true
447    o add PTRACERS (PTR0[1-5]) to testreport output
448    o exf_check_range:
449      * default changed to .TRUE.
450      * will check values for niter0 if debLevA, every timestep if debLevB
451      * STOP in exf_check_range if 'out of range'
452      * range chosen generous to allow for potential extema
453      TBD: a version with stricter range
454           permitted range would be runtime parameters
455  o GMredi:  o GMredi:
456    - fix ldd97 slope limit ; extend valid domain of Psi-Bolus ;    - fix ldd97 slope limit ; extend valid domain of Psi-Bolus ;
457    - change S/R GRAD_SIGMA to be valid in the overlap on CS-grid.    - change S/R GRAD_SIGMA to be valid in the overlap on CS-grid.

463      - renamed PTRACERS_SEPARATE_FORCING to GCHEM_SEPARATE_FORCING;
464        this flag is now only visible within GCHEM-pkg routines.
465      - moved gchem_forcing_int temporarily into ptracers_forcing, this will
466        be replaced by a 3D array that is computed before thermodynamics; for
467        this, the tracer ID iTracer had to be included into the parameter list
468        of ptracers_forcing
469      - set up forward_step to call gchem_forcing, that will replace
470        gchem_forcing_int in ptracers_forcing
471      - cleaning up
472  o small cleaning of exch2: remove files that are also in eesupp/src  o small cleaning of exch2: remove files that are also in eesupp/src
