4      Notes on tags used in MITgcmUV      Notes on tags used in MITgcmUV
5      ==============================      ==============================
6    
7    o add brackets in multi-terms sum to get same truncation, independent of
8      the face number (manage to get exactly same value of gU,gV at the cs-edge)
9      affects several test. exp. Update global_ocean.cs32x15 (+.thsice).
10    o Clean, new version of mom_calc_visc.  Adds a new feature, viscAhRemax
11      and viscA4Remax, which allow one to limit the minimum viscosity by specifying
12      a maximum grid-scale Reynolds number.  Also, changes all length calculations
13      in the case of grid anisotropy to geometric mean of dx**2 and dy**2.
14      Suggested values of viscosity parameters found in mom_calc_visc.
15      Many new viscosity diagnostics available.
16    
17    checkpoint57s_post
18    o Add clearing-house for viscosity calculations, mom_calc_visc and
19      correct numerous bugs in LeithD and Smagorinsky discretizations.  
20      mom_calc_visc now allows for Smagorinsky, Leith and LeithD to be
21      used simultaneously, and to be used in mom_vecinv and mom_fluxform.
22      Mom_vecinv can be used with standard viscous calculation (mom_vi_hdissip.F)
23      and with Strain-Tension viscous term calculation (mom_hdissip.F).  
24      The Strain-Tension form is now called with useStrainTensonVisc=.true.
25      ViscAhStrain and viscAhTension are now retired.
26    o diagnostics "VISCAHD" & "VISCA4D" replace "VISCAH" & "VISCA4".
27    o In response to JMC's bug report, genmake2 now ignores any soft-links
28      that it finds in the *current* directory when searching for files.
29      Soft-links found in any other source directories will still work as
30      they did before.
31    o add HAVE_SETRLSTK define and useSETRLSTK flag (eedata) which calls
32      a C routine to unlimit the stack size
33    o mnc-ify pkg/aim snapshot vars
34    o mnc-ify pkg/land as requested by Daniel
35    o various changes to mnc including:
36      - all files use the new "BASENAME[[.ITER].{t|f}NUM].nc" format
37      - output can now be grouped so that all files within a group
38          change the ITER portion of their names in lock-step together
39      - can now read ("global") PER-FACE (in addition to PER-TILE) files
40          and works with both EXCH1 and EXCH2 (but needs more testing)
41      - writing works for all verification test cases w/ g77 on Linux
42    
43    checkpoint57r_post
44    o make MNC variable initialization happen earlier
45    o add diagnostics for (almost) each term of the momentum Eq.
46    o remove SST,SSS,UVEL_k2,VVEL_k2 diagnostics.
47    o move pkg timeave out of pkg-groups "oceanic" & "atmospheric" (pkg/pkg_groups)
48    o remove MINIMAL_TAVE_OUTPUT option ;
49      add "dumpInitAndLast" to replace "nodumps" (and MINIMAL_TAVE_OUTPUT).
50    o move some basic S/R (used elsewhere in the code) from pkg/mdsio to eesupp/src
51      allows to compile without pkg/mdsio (& test successfully hs94.1x64x5)
52    o add MNC output for adjoint of EXF (adexf), SEAICE (adseaice)
53    o add time-dependent SST, SSS control
54    o cost terms in ecco/ modularized (new cost_generic.F)
55    o cost_averages routines are modularized (new cost_averagesgeneric.F)
56    o new infrastructure for seaice model vs. obs misfits in seaice/
57      * driver from the_main_loop.F is seaice_cost_driver.F
58      * first term is AREA vs. SMR observation misfit (ALLOW_SEAICE_COST_SMR_AREA)
59      * gradient check in Exp. 6a of natl_box_adjoint/
60    o natl_box_adjoint input_seaice for Lab. Sea now available online via wget
61      (see README file)
62    
63    checkpoint57q_post
64    o fix initialisation Pb in calc_gw (get NANs in exp5 with g77)
65    o fix annoying months-old bug in mnc/mdsio output for seaice pkg
66      - bug was reported by Jean-Michel and Ian Fenty
67    o fix initialization Pb in AIM-Ocean coupled model (aim_sice2aim.F)
68      update exp. cpl_aim+ocn output.
69    o Implement 4-level checkpointing: AUTODIFF_4_LEVEL_CHECKPOINT
70      Needed for high-res. runs with large global files
71      to be able to limit tapelev size
72    o Changed some tests for adjoint:
73      * carbon/ now tests AUTODIFF_2_LEVEL_CHECKPOINT
74      * natl_box_adjoint/code_bulk/ tests AUTODIFF_4_LEVEL_CHECKPOINT
75      * global_ocean.90x40x15/ back to default 3-level checkpointing
76    o Modifications to enable scripted COMMON to MODULE conversion
77      * verification/OpenAD/code/ has necessary scripts and description;
78      * converts, compiles and runs successfully;
79    
80    checkpoint57p_post
81    o reading of delXfile & delYfile moved from ini_parms.F to ini_grid.F
82    o move ${PKG}_MNC_INIT from ${PKG}_READ_PARAMS to ${PKG}_INIT_FIXED
83      (already the case for some pkgs, including recent MNC_init, e.g. thsice)
84    o call CALC_GW from DYNAMICS (instead of from FORWARD_STEP)
85    o Dissipation & phiHyd gradient are always added to gU,gV in timestep.F
86      (was already the case for dissipation with mom_vecinv,
87       and also the case for grad.PhiHyd when staggered-timeStep)
88      This will allow to put dissipation out-off the AB time-stepping.
89     Unfortunately, affects truncation error. Update output of exp. that "fails"
90      (cg2d matching number) and leave the others for later: front_relax(10),
91      global_ocean_pressure(10),ideal_2D_oce(10),internal_wave(9),lab_sea(12),
92      matrix_example(7!),natl_box(12),plume_on_slope(11),vermix(12x3,11x2).
93    
94    checkpoint57o_post
95    o fix MNC/MDSIO flags in PTRACERS so that (1) it works, and
96      (2) its ready to be documented during the 20050801 DocFest
97    o MNC-ify the gmredi package -- tested and works w/ and w/o mnc
98      for ideal_2D_oce and lab_sea on linux_ia32_g77
99    o set to #undef CTRL_SET_OLD_MAXCVARS_30
100      in global1x1_tot/code_seaice_adj to access indices 32, 33
101      (worth another tag)
102    
103    checkpoint57n_post
104    o adding precip control xx_precip 32
105    o adding swflux control xx_swflux 33
106    o Replacing 10 forcing penalty cost routines by 1 generic.
107    o Implementing partitioning in time-mean and variable adjustment
108      for atmos. state.
109    o Time-mean constant error is now read in data.ecco (instead of hard-coded)
110    o in natl_box_adjoint:
111      * updated exp 1 to 10
112        (but does not have time-mean vs. variable split results yet)
113    o updated global1x1/*_seaice_adj/
114      to incorporate latest changes
115    o enable useSingleCpuIO for mdsio vector routines
116      (applies in particular to tapelev I/O)
117    o removed inefficient K-loop in all active_file*control*.F
118    
119    checkpoint57m_post
120    o re-arrange exp. adjustment.cs-32x32x1 (adjust_nlfs.cs-32x32x1 merge into)
121      and advect_cs (use EXCH-2 and standard cs-32 grid files).
122    o pkg/exch2: filling of face-corner halo regions is optional
123      (ifdef W2_FILL_NULL_REGIONS) and is turned off by default.
124    
125    checkpoint57l_post
126     tag before updating tutorials (pre-release-2)
127    o add cos & sin of grid-direction orientation angle (curvilinear grid only,
128       for output and interpolation of input fields onto model grid)
129    o fix radius in mom_v_metric_cylinder.F (wrong by dy/2).
130       Affects results of exp. rotating_tank ; update output.txt.
131    o pkg/diagnostics: 2 new S/R to fill a diagnostics using a scaling factor
132          and taking the square quantity and/or using a fraction-weight field.
133    o fix aim_diagnostics_init.F mate numbers.
134    o add mnc output capability to diagnostics/diagstat and update
135      our cvsignore files for the ACSII output generated
136    
137    checkpoint57k_post
138    o lab_sea now uses diagnostics package and provides a suite of
139      new EXF diagnostics output.
140    
141    checkpoint57j_post
142    o exf
143      * bug fix in exf_bulkformulae for psimh (spotted by Eliyahu Biton):
144        Bracket missing in eqn. for psimh (eqn. 7 of Large & Pond, 1982);
145        terms -2*ATAN(x) + pi/2 were added to both stable and unstable case.
146      * extended diagnostics output
147        - now includes all EXF variables
148        - hs, hl moved to common block
149        - separate S/R for diagnostics, called after ctrl vector is added
150        - name changed for EXFsw -> EXFswnet, EXFlw -> EXFlwnet
151        - EXFqnet contains true Qnet (i.e. includes qsw)
152      * updated verif. lab_sea, global_with_exf
153      * Rearranging hflux (exf_mapfields -> exf_getforcing)
154        to ensure that diagnostics sees a true EXFqnet
155    o add matlab scripts for CS-grid vectors (in utils/cs_grid)
156    o diagnostics pkg: change pointers so that 1 diagnostic can be used
157      several times with different frequencies.
158    o mnc-ify the thsice package as requested by Daniel Enderton
159      - the monitor--MNC output needs work
160      - many attributes need to be added (most are currently blank)
161    o mnc-ify theaim_v23 package as requested by Daniel Enderton
162      - many attributes need to be added (most are currently blank)
163    o remove "groundAtK1" & "rkFac" (replaced by usingPCoords & -rkSign)
164    o add Sadourny like discretization to the 4th.O vorticity advection scheme
165    o fix bug in rStar code (calc_r_star.F) when used with topo/bathy.
166      update output.txt from: aim.5l_cs (& .thSI), cpl_aim+ocn,
167         fizhi-gridalt-hs and global_ocean.cs32x15 (& .thsice).
168    o fix few little things to avoid floating error with -ftrapuv (ifort v9)
169     (ini_spherical_polar_grid.F, calc_r_star.F, monitor/mon_surfcor.F)
170    
171    checkpoint57i_post
172    o Diagnostics package was changed: diagnostic allocation is now deactivated
173      by setting an empty file name in the namelist (used to be by setting 0 frequency)
174    o momentum advection (VI form) options: activate 4th.O vorticity Coriolis ;
175      add 1rst Order upwind vertical Shear.
176    o add a quick fix for A/B checkpointing in OFFLINE mode
177    o add IGNORE_TIME define and -ignore_time option to genmake2 as an
178      end-run around the C/Fortran linking horror in eesup/src/timers.F
179    o added pkg/runclock: allows user to terminate run based on wall clock
180    o added non-hydrostatic scaling parameter: nh_am2
181    o pkg/my82: futile attempt to make results compiler-independent by adding
182      some "_d 0", etc. no effect.
183    o for mnc output, fill the 'T' coordinate var with myTime and create a
184      separate 'iter' variable for iteration count
185    o pkg/diagnostics:
186      add new capability: output of Global/Regional & per-level statistics ;
187      tested against monitor output (including land & thSIce) on various exp.
188    o make seaice-pkg I/O type flags (MNC/MDS) more standard.
189    
190    checkpoint57h_done
191      tag after changing user customized files (DIAGNOSTICS_SIZE.h,
192      data.diagnostics, data.gchem, data.ptracers) is done.
193    
194    o pkg/diagnostics: prepare for Global/Regional statistics.
195      add 2nd namelist in data.diagnostics and update DIAGNOSTICS_SIZE.h
196    o remove "baseTime" (no used) from arg. list of DIFF_BASE_MULTIPLE
197      and rename it: DIFFERENT_MULTIPLE
198    
199    checkpoint57h_post
200    o move tIter0 from data.gchem to PTRACERS_Iter0 in data.ptracers
201    o pkg/diagnostics: change output frequency, now in seconds (instead
202      of Nb of iterations). This requires to change data.diagnostics.
203    checkpoint57h_pre
204    
205    o in mnc, let the user create the output dir if both mnc_outdir_date
206      and mnc_outdir_num are false
207    o add fflags() to pkg/diagnostics which allows one to specify, on a
208      per-file basis, the file precision [default behavior is unchanged]
209    o added diagnostics to pkg/kpp, including computation of mixed layer
210      depth based on a temperature/density criterion
211    o updated verification/natl_box to test the new pkg/kpp diagnostics
212    o bugs fixed (with useAbsVorticity=T & with useJamartMomAdv=T)
213    o test AB-3 code with 4th.Order advection scheme (advect_xy/input.ab3_c4)
214    o fix mnc flags in pkg/seaice so that they are "owned" by seaice,
215      not mnc -- this mistake was found by JMC and is now corrected
216    
217    checkpoint57g_post
218    o add Adams-Bashforth 3rd Order time stepping:
219      - default remains AB-2 (#undef ALLOW_ADAMSBASHFORTH_3)
220      - not yet implemented with NH, CD_Scheme, pTracers, MNC_pickup ...
221    checkpoint57g_pre
222    
223    o make lambda[Theta,Salt]ClimRelax spatially varying
224      (default remains spatially uniform constant based on tau)
225    o added new control variables
226      * init. uVel, vVel, etanN
227      * lambda[Theta,Salt]ClimRelax
228    o separate masks used for ctrl_pack/unpack 'from write_grid' output
229      (suggested by G. Forget)
230    
231    checkpoint57f_post
232    o add parameter "baseTime" = model base time = time at iteration zero
233      new function DIFF_BASE_MULTIPLE (replace DIFFERENT_MULTIPLE) to
234      account for baseTime shift
235    o move Coriolis arrays from PARAMS.h to GRID.h
236    checkpoint57f_pre
237    
238    o mnc-ifying the seaice package
239    o introduced an alternative length scale calculation for use in the limiting
240      maximum viscosity (off by default, see mom_vi_hdissip.F for details)
241    o S/R ptracers_calc_diff: argument list bug for CALL KPP_CALC_DIFF_S
242    o added modified Leith scheme with viscosity proportional to grad(Hdiv)
243      as well as grad(vort3).  Made it compatible with both approximate form
244      for the cubed sphere and full form of these gradients.  Added flag
245      useFullLeith to select between approximate and full form.  
246    o add "d0" in getcon.F to reduce differences between compilers/platforms
247      update output.txt of exp. fizhi-gridalt-hs
248    o change port_rand funtion to allow to set the seed.
249    o fix obscure MNC bug involving conversion between reals and integers
250      - it caused no problems with certain (eg. gcc, ifc) compilers but the
251        new version is now more standards-compliant
252    o adjoint-related modifications
253      * gad_dst3_adv_?: to be able to use advscheme=30 in adjoint
254      * gad_calc_rhs: fool adjoint, revert to advscheme=30 in reverse when using 33
255      * mom_vi_hdissip: to be able to use Leith scheme in adjoint
256    
257    checkpoint57e_post
258    o Adding eddy stress controls a la Ferreira et al.
259    checkpoint57e_pre (actually was tagged: eckpoint57e_pre)
260    
261    o fizhi pkg: fix AtoC and CtoA when called with same input & output array
262      update output.txt of exp. fizhi-gridalt-hs
263    o add more "Z" dimensions and associated coordinate vars to MNC
264    o pkg/exf: added twoDigitYear capability for option useExfYearlyFields
265    o parameter calendarDumps: when set, approximate months (30-31 days) and years
266      (360-372 days) for parameters chkPtFreq, pChkPtFreq, taveFreq, SEAICE_taveFreq,
267      KPP_taveFreq, and freq in pkg/diagnostics are converted to exact calendar
268      months and years.  Requires pkg/cal.
269    o diagnostics: add pickup functionality
270      - off by default for backwards compatibility
271      - current version only uses MDSIO -- MNC will be added
272    o allow to use pkg diagnostics for LAND pkg output & Shapiro Tendencies.
273    o pkg/shap_filt: fix for multi-tiles per face (CS-grid with EXCH2)
274    
275    checkpoint57d_post
276    o pkg/thsice used in the ocean: fix tile Pb related to sIceLoad forcing
277    o modify verification/ideal_2D_oce so that it tests the creation of mnc
278      output from the diagnostics package
279    o temporary fix in EXCH2_UV: add a 3rd call to fix the 24.tiles CS-grid set-up
280    o make genmake2 more portable by using ".$FS" instead of ".f" for more
281      of the test compilations (eg. IBM xlf on Mac OSX w/HFS filesys)
282    o add coordinate variables to the MNC output from the diagnostics package
283    o change MNC-flags default value: true when useMNC=TRUE
284    o add a "readgrid_mnc" flag to MNC and give model/src/ini_curvilinear_grid.F
285      the ability (off by default) to read the grid information using MNC
286    o lab_sea: use LSR_ERROR=1.E-12 for testing ; update output.txt
287    o diagnostics: fix a bug (sub-set of levels); keep full precision when averaging
288    o do snap-shot diagnostics at the middle of the time-interval (instead of
289      at the end).
290    o update exp. aim.5l_cs (use default LAND_OPTIONS.h file) and add
291      new test for AIM with thSIce + slab-ocean
292    o cpl_aim+ocn test: update output (optfile & default GMREDI_OPTIONS.h)
293    o move state variable diagnostics to the beginning of the time step ;
294      (note: still needs some work specially for snap-shot diagnostics)
295      duplicate & replace UVELVVEL diagnostics with UV_VEL_C & UV_VEL_Z
296    
297    checkpoint57c_post
298    o Change testing option (-ieee) to get closer agreement between g77 & ifort
299    o generate new output.txt files on faulks with g77 & the new -ieee option
300    checkpoint57c_pre
301    
302    o add "_d 0" in freeze ; change some "FLOAT" to "DFLOAT" and went back (TAF);
303      update output.txt of exp. global_ocean.90x40x15
304    o fix in ini_eos.F (one "_d 0" was missing): now g77 & ifc give much closer
305      results; update global_ocean_pressure & global_ocean.cs32x15 output.txt
306    o add saltFlux(+File) forcing capability with periodicExternalForcing
307    o allow to use pkg diagnostics for GM-Redi & ThSIce output
308    o diagnostics_fill: fill in up to sNx+1 or sNy+1 (if U,V or Z pt) for mnc.
309    o improvements for the MNC output from DIAGNOSTICS:
310      - correct handling of the unlimitied dimension
311      - all dims now have associated coordinate variables
312      - variables located at U, V, and Corner ("Z") points are now written
313        with the correct horzontal dimensions (eg. 'Xp1', 'Yp1') so that
314        *all* data points are output
315    o added seaice_summary.F and removed obsolete ALLOW_SEAICE's from pkg/seaice
316    o added pkg/seaice/seaice_monitor.F
317    o mdsio_readfield.F can now read files visible only to master MPI process.
318    o pkg/seaice: some test code for ice-modified ocean stress
319    o exf_getffields interpolation defaults to bilinear for all scalar forcing
320      fields (remains bicubic for wind velocity and stress).  This avoids, e.g.,
321      spurious negative numbers for precipitation and humidity.  Will cause
322      some small numerical differences for integrations using pkg/exf/exf_interp.F.
323    o pkg/ctrl/
324      * Add ctrlvec diagnostics in pack/unpack for nondimensional I/O
325        May be enabled via doPackDiag
326      *  introduce z-scaling of
327         + gradient (doZscalePack) and
328         + control (doZscaleUnpack)
329    o pkg/mdsio/
330      * enable useSingleCpuIO for state estimation (ctrl_pack/unpack) mdsio_gl.F
331      * N.B.: leave tiled I/O for tapelev (i.e. mds...vector)
332    
333    checkpoint57b_post
334    o simplify options in diagnostics_fill arguments (remove weird combinations)
335    o fix MNC coordinate variables so that they now contain per-face index
336      values (instead of xC,xG,yC,yG values) when run with EXCH2 since, in
337      general, EXCH2 grids are only aligned to a "local" coordinate system
338    o test diagnostics pkg in dic_example (no output) and ideal_2D_oce (with ouput)
339    o Implement instantaneous output within pkg diagnostics:
340      setting a negative frequency in data.diagnostics produces
341     "snap-shot" output (as opposed to time-average if freq > 0)
342    o move out off EQUIVALENCE all diagnostics that fizhi does not use ;
343      NOTE: change ptracer diagnostics name: use 2 characters to work with
344            more than 9 tracers. Add also diagnostics of advect & diffus flux.
345    o more CF compliance: convert all MNC 'iter' variables to 'T' so that it
346      becomes the coordinate variable for the 'T' dimension
347    o add CF-style coordinate variables to MNC
348      - just a first cut:  numbers are meaningless on the cubesphere and
349        missing along the T axis but otherwise it works!
350    o add surface flux diagnostics: TAUX, TAUY, TFLUX, TRELAX, TICE, SFLUX, SRELAX
351    o pkg/thSIce: read initial state from 6 files ; allow monitor to use MNC.
352    o add diagnostics of advective & diffusive flux for T & S (pTracers coming soon)
353      this is based directly on what the model compute, so that the content of
354      each diagnostics might be affected by switching options (e.g., implicitDiffusion)
355    o small changes for diagnostics (gad_biharm_?.F, arguments of S/R impldiff.F)
356    o clean up build options files for SunOS, in particular
357      - remove -traditional from xmakedepend
358      - change -xarch=v9 to -xarch=native for f77
359      - restore use of make (not gmake)
360      - add CC=gcc if using g77
361    o changes per discussion of AM, JMC, & EH3 today:
362      - move redundant "grid" variables out of "state" -- in preparation of
363        creating proper CF-style coordinate variables and in recognition
364        that any/all grid variables can be easily copied (eg. w/NCO) from
365        the grid files into any of the other NetCDF files
366      - *always* output grid variables with MDSIO (this will eventually be
367        changed)
368      - output MNC grid file if useMNC is true
369    o every instance of _END_MASTER() has been found and replaced with
370      _END_MASTER( myThid ) in order to satisfy certain picky Sun
371      preprocessors
372    o re-arrange diagnostics pkg initialisation:
373     - allow each package to extend the available diagnostics list
374     - add some checking and fix small problems (multi-threaded, ...)
375     - new S/R diagnostics_fill (replace fill_diagnostics):
376       look through the short list of active diag. (instead of the long list)
377       create function DIAGNOSTICS_IS_ON to tell if a diagnostics is active
378    
379    checkpoint57a_post
380    o this set of changes restores TAMC compatibility
381      tested for global_ocean.90x40x15 adjoint on trough
382      (what a pain)
383    
384    checkpoint57a_pre
385    o some modifs in tools/build_options for sunos
386    o call ctrl_pack for ctrl at end for optimcycle=0
387    
388    checkpoint57
389    o add horizontal bi-harmonic viscosity for vertical velocity
390      - new parameter viscA4W (defaults to viscA4)
391      - affects only non-hydrostatic code
392      - to be done: no-slip lateral boundary conditions
393    o switch back to "sflux = sflux - runoff" in exf_getforcing.F
394    o implement Implicit Vertical advection for pTracers
395    o depth convergence accelerator: replace deltaTtracer by dTtracerLev(k)
396      (implemented also for implicit vertical diffusion & advection)
397    o OBCS: extend application of tracer open boundary conditions
398      to a strip beyond the boundary of width Olx/Oly
399    o add call monitor to TAF set of required calls (flow directives)
400      and include in natl_box_adjoint
401    o untangle a few ifdefs related to cost, ctrl, autodiff
402      untangel a few ALLOW_ECCO_OPTIMIZATION
403    o Apply Cooper & Haines representative estimates also at sub-surface (k=Nr)
404      (theta2, salt2 in ecco_cost_weights)
405    
406    checkpoint56c_post
407    o OBCS as control variables
408      - update ctrl_ad_diff.list, obcs_ad_diff.list
409      - remove balance of obcs controls from default
410      - fix index bug nobcs in ctrl_init
411      - fix dummy fields filen in ctrl_pack
412      - add dummy weights for obcs
413    o lsopt: comment out fort.94 output
414    o optim:
415      - remove unnecessary header files
416      - adjusted namelists
417      - add xerbla.F to Makefile
418    o exf:
419      - multiple modifications of exf_check_range
420      - unit change in exf_init_runoff from [m/year] to [m/s]
421    o mdsio:
422      - i/o-vector change debugLevel from debLevA to debLevB
423    
424    checkpoint56b_post
425    o collect all ptracers output in an new routine (PTRACERS_OUTPUT) that
426      is called from DO_THE_MODEL_IO
427      - rename PTRACERS_STATV_WRITE to PTRACERS_WRITE_TIMEAVE
428      - introduce new parameter PTRACERS_dumpFreq (defaults to dumpFreq)
429      - clean up PTRACERS_WRITE_TIMEAVE a little
430    o add another verification experiment that tests both the cfc-pkg and
431      the gchem-pkg with GCHEM_SEPARATE_FORCING undefined, that is with
432      reactive tendencies treated inline with regular timestepping
433    o testreport previously did a lousy job of comparing small numbers, so
434      we (Ed and Martin) changed the  way the cut-off of 1.e-12 is
435      implemented in the little c-progam tmp_cmpnum.c which is embedded in
436      testreport.
437    o ptracers_monitor: bug fix for MPI
438    
439    checkpoint56a_post
440    o GCHEM: finish reorganizating the package
441      - forward_step calls GCHEM_CALC_TENDENDY, which computes gchemTendency
442        (introduces another 3D-array for each passive tracer, but only if
443        GCHEM_SEPARATE_FORCING is undefined. For GCHEM_SEPARATE_FORCING
444        gchemTendency is not needed because the timestep is done separately)
445      - gchemTendency is added to gPtr in GCHEM_ADD_TENDENCY
446      - GCHEM is now---more or less cleanly---separate from PTRACERS
447      - to bo done: handling of surfaceForcingPtr that is needed for KPP not
448        so clear to me how that should be done in a general way.
449    o CFC: improve formatting of output in CFC_ATMOS
450    o PTRACERS:
451      - rename GCHEM_MONITOR to PTRACERS_MONITOR and call it from MONITOR, so
452        that ALL experiments with ptracers enable can be checked. This makes
453        GCHEM_MONITOR obsolete.
454      - include a runtime parameter PTRACERS_monitorFreq that defaults to
455        monitorFreq
456      - set default PTRACERS_write_mdsio to false if PTRACERS_write_mnc is true
457    o add PTRACERS (PTR0[1-5]) to testreport output
458  o exf_check_range:  o exf_check_range:
459    * default changed to .TRUE.    * default changed to .TRUE.
460    * will check values for niter0 if debLevA, every timestep if debLevB    * will check values for niter0 if debLevA, every timestep if debLevB
