4      Notes on tags used in MITgcmUV      Notes on tags used in MITgcmUV
5      ==============================      ==============================
6    o Add clearing-house for viscosity calculations, mom_calc_visc and
7      correct numerous bugs in LeithD and Smagorinsky discretizations.  
8      mom_calc_visc now allows for Smagorinsky, Leith and LeithD to be
9      used simultaneously, and to be used in mom_vecinv and mom_fluxform.
10      Mom_vecinv can be used with standard viscous calculation (mom_vi_hdissip.F)
11      and with Strain-Tension viscous term calculation (mom_hdissip.F).  
12      The Strain-Tension form is now called with useStrainTensonVisc=.true.
13      ViscAhStrain and viscAhTension are now retired.
14    o  diagnostics "VISCAHD" & "VISCA4D" replace "VISCAH" & "VISCA4".
15    o In response to JMC's bug report, genmake2 now ignores any soft-links
16      that it finds in the *current* directory when searching for files.
17      Soft-links found in any other source directories will still work as
18      they did before.
19    o add HAVE_SETRLSTK define and useSETRLSTK flag (eedata) which calls
20      a C routine to unlimit the stack size
21    o mnc-ify pkg/aim snapshot vars
22    o mnc-ify pkg/land as requested by Daniel
23    o various changes to mnc including:
24      - all files use the new "BASENAME[[.ITER].{t|f}NUM].nc" format
25      - output can now be grouped so that all files within a group
26          change the ITER portion of their names in lock-step together
27      - can now read ("global") PER-FACE (in addition to PER-TILE) files
28          and works with both EXCH1 and EXCH2 (but needs more testing)
29      - writing works for all verification test cases w/ g77 on Linux
30    
31    checkpoint57r_post
32    o make MNC variable initialization happen earlier
33    o add diagnostics for (almost) each term of the momentum Eq.
34    o remove SST,SSS,UVEL_k2,VVEL_k2 diagnostics.
35    o move pkg timeave out of pkg-groups "oceanic" & "atmospheric" (pkg/pkg_groups)
36    o remove MINIMAL_TAVE_OUTPUT option ;
37      add "dumpInitAndLast" to replace "nodumps" (and MINIMAL_TAVE_OUTPUT).
38    o move some basic S/R (used elsewhere in the code) from pkg/mdsio to eesupp/src
39      allows to compile without pkg/mdsio (& test successfully hs94.1x64x5)
40    o add MNC output for adjoint of EXF (adexf), SEAICE (adseaice)
41    o add time-dependent SST, SSS control
42    o cost terms in ecco/ modularized (new cost_generic.F)
43    o cost_averages routines are modularized (new cost_averagesgeneric.F)
44    o new infrastructure for seaice model vs. obs misfits in seaice/
45      * driver from the_main_loop.F is seaice_cost_driver.F
46      * first term is AREA vs. SMR observation misfit (ALLOW_SEAICE_COST_SMR_AREA)
47      * gradient check in Exp. 6a of natl_box_adjoint/
48    o natl_box_adjoint input_seaice for Lab. Sea now available online via wget
49      (see README file)
50    
51    checkpoint57q_post
52    o fix initialisation Pb in calc_gw (get NANs in exp5 with g77)
53    o fix annoying months-old bug in mnc/mdsio output for seaice pkg
54      - bug was reported by Jean-Michel and Ian Fenty
55    o fix initialization Pb in AIM-Ocean coupled model (aim_sice2aim.F)
56      update exp. cpl_aim+ocn output.
57    o Implement 4-level checkpointing: AUTODIFF_4_LEVEL_CHECKPOINT
58      Needed for high-res. runs with large global files
59      to be able to limit tapelev size
60    o Changed some tests for adjoint:
61      * carbon/ now tests AUTODIFF_2_LEVEL_CHECKPOINT
62      * natl_box_adjoint/code_bulk/ tests AUTODIFF_4_LEVEL_CHECKPOINT
63      * global_ocean.90x40x15/ back to default 3-level checkpointing
64    o Modifications to enable scripted COMMON to MODULE conversion
65      * verification/OpenAD/code/ has necessary scripts and description;
66      * converts, compiles and runs successfully;
67    
68    checkpoint57p_post
69    o reading of delXfile & delYfile moved from ini_parms.F to ini_grid.F
70    o move ${PKG}_MNC_INIT from ${PKG}_READ_PARAMS to ${PKG}_INIT_FIXED
71      (already the case for some pkgs, including recent MNC_init, e.g. thsice)
72    o call CALC_GW from DYNAMICS (instead of from FORWARD_STEP)
73    o Dissipation & phiHyd gradient are always added to gU,gV in timestep.F
74      (was already the case for dissipation with mom_vecinv,
75       and also the case for grad.PhiHyd when staggered-timeStep)
76      This will allow to put dissipation out-off the AB time-stepping.
77     Unfortunately, affects truncation error. Update output of exp. that "fails"
78      (cg2d matching number) and leave the others for later: front_relax(10),
79      global_ocean_pressure(10),ideal_2D_oce(10),internal_wave(9),lab_sea(12),
80      matrix_example(7!),natl_box(12),plume_on_slope(11),vermix(12x3,11x2).
81    
82    checkpoint57o_post
83    o fix MNC/MDSIO flags in PTRACERS so that (1) it works, and
84      (2) its ready to be documented during the 20050801 DocFest
85    o MNC-ify the gmredi package -- tested and works w/ and w/o mnc
86      for ideal_2D_oce and lab_sea on linux_ia32_g77
87    o set to #undef CTRL_SET_OLD_MAXCVARS_30
88      in global1x1_tot/code_seaice_adj to access indices 32, 33
89      (worth another tag)
90    
91    checkpoint57n_post
92    o adding precip control xx_precip 32
93    o adding swflux control xx_swflux 33
94    o Replacing 10 forcing penalty cost routines by 1 generic.
95    o Implementing partitioning in time-mean and variable adjustment
96      for atmos. state.
97    o Time-mean constant error is now read in data.ecco (instead of hard-coded)
98    o in natl_box_adjoint:
99      * updated exp 1 to 10
100        (but does not have time-mean vs. variable split results yet)
101    o updated global1x1/*_seaice_adj/
102      to incorporate latest changes
103    o enable useSingleCpuIO for mdsio vector routines
104      (applies in particular to tapelev I/O)
105    o removed inefficient K-loop in all active_file*control*.F
106    
107    checkpoint57m_post
108    o re-arrange exp. adjustment.cs-32x32x1 (adjust_nlfs.cs-32x32x1 merge into)
109      and advect_cs (use EXCH-2 and standard cs-32 grid files).
110    o pkg/exch2: filling of face-corner halo regions is optional
111      (ifdef W2_FILL_NULL_REGIONS) and is turned off by default.
112    
113    checkpoint57l_post
114     tag before updating tutorials (pre-release-2)
115    o add cos & sin of grid-direction orientation angle (curvilinear grid only,
116       for output and interpolation of input fields onto model grid)
117    o fix radius in mom_v_metric_cylinder.F (wrong by dy/2).
118       Affects results of exp. rotating_tank ; update output.txt.
119    o pkg/diagnostics: 2 new S/R to fill a diagnostics using a scaling factor
120          and taking the square quantity and/or using a fraction-weight field.
121    o fix aim_diagnostics_init.F mate numbers.
122    o add mnc output capability to diagnostics/diagstat and update
123      our cvsignore files for the ACSII output generated
124    
125    checkpoint57k_post
126    o lab_sea now uses diagnostics package and provides a suite of
127      new EXF diagnostics output.
128    
129    checkpoint57j_post
130    o exf
131      * bug fix in exf_bulkformulae for psimh (spotted by Eliyahu Biton):
132        Bracket missing in eqn. for psimh (eqn. 7 of Large & Pond, 1982);
133        terms -2*ATAN(x) + pi/2 were added to both stable and unstable case.
134      * extended diagnostics output
135        - now includes all EXF variables
136        - hs, hl moved to common block
137        - separate S/R for diagnostics, called after ctrl vector is added
138        - name changed for EXFsw -> EXFswnet, EXFlw -> EXFlwnet
139        - EXFqnet contains true Qnet (i.e. includes qsw)
140      * updated verif. lab_sea, global_with_exf
141      * Rearranging hflux (exf_mapfields -> exf_getforcing)
142        to ensure that diagnostics sees a true EXFqnet
143    o add matlab scripts for CS-grid vectors (in utils/cs_grid)
144    o diagnostics pkg: change pointers so that 1 diagnostic can be used
145      several times with different frequencies.
146    o mnc-ify the thsice package as requested by Daniel Enderton
147      - the monitor--MNC output needs work
148      - many attributes need to be added (most are currently blank)
149    o mnc-ify theaim_v23 package as requested by Daniel Enderton
150      - many attributes need to be added (most are currently blank)
151    o remove "groundAtK1" & "rkFac" (replaced by usingPCoords & -rkSign)
152    o add Sadourny like discretization to the 4th.O vorticity advection scheme
153    o fix bug in rStar code (calc_r_star.F) when used with topo/bathy.
154      update output.txt from: aim.5l_cs (& .thSI), cpl_aim+ocn,
155         fizhi-gridalt-hs and global_ocean.cs32x15 (& .thsice).
156    o fix few little things to avoid floating error with -ftrapuv (ifort v9)
157     (ini_spherical_polar_grid.F, calc_r_star.F, monitor/mon_surfcor.F)
158    
159    checkpoint57i_post
160    o Diagnostics package was changed: diagnostic allocation is now deactivated
161      by setting an empty file name in the namelist (used to be by setting 0 frequency)
162    o momentum advection (VI form) options: activate 4th.O vorticity Coriolis ;
163      add 1rst Order upwind vertical Shear.
164    o add a quick fix for A/B checkpointing in OFFLINE mode
165    o add IGNORE_TIME define and -ignore_time option to genmake2 as an
166      end-run around the C/Fortran linking horror in eesup/src/timers.F
167    o added pkg/runclock: allows user to terminate run based on wall clock
168    o added non-hydrostatic scaling parameter: nh_am2
169    o pkg/my82: futile attempt to make results compiler-independent by adding
170      some "_d 0", etc. no effect.
171    o for mnc output, fill the 'T' coordinate var with myTime and create a
172      separate 'iter' variable for iteration count
173    o pkg/diagnostics:
174      add new capability: output of Global/Regional & per-level statistics ;
175      tested against monitor output (including land & thSIce) on various exp.
176    o make seaice-pkg I/O type flags (MNC/MDS) more standard.
177    
178    checkpoint57h_done
179      tag after changing user customized files (DIAGNOSTICS_SIZE.h,
180      data.diagnostics, data.gchem, data.ptracers) is done.
181    
182    o pkg/diagnostics: prepare for Global/Regional statistics.
183      add 2nd namelist in data.diagnostics and update DIAGNOSTICS_SIZE.h
184    o remove "baseTime" (no used) from arg. list of DIFF_BASE_MULTIPLE
185      and rename it: DIFFERENT_MULTIPLE
186    
187    checkpoint57h_post
188    o move tIter0 from data.gchem to PTRACERS_Iter0 in data.ptracers
189    o pkg/diagnostics: change output frequency, now in seconds (instead
190      of Nb of iterations). This requires to change data.diagnostics.
191    checkpoint57h_pre
192    
193    o in mnc, let the user create the output dir if both mnc_outdir_date
194      and mnc_outdir_num are false
195    o add fflags() to pkg/diagnostics which allows one to specify, on a
196      per-file basis, the file precision [default behavior is unchanged]
197    o added diagnostics to pkg/kpp, including computation of mixed layer
198      depth based on a temperature/density criterion
199    o updated verification/natl_box to test the new pkg/kpp diagnostics
200    o bugs fixed (with useAbsVorticity=T & with useJamartMomAdv=T)
201    o test AB-3 code with 4th.Order advection scheme (advect_xy/input.ab3_c4)
202    o fix mnc flags in pkg/seaice so that they are "owned" by seaice,
203      not mnc -- this mistake was found by JMC and is now corrected
204    
205    checkpoint57g_post
206    o add Adams-Bashforth 3rd Order time stepping:
207      - default remains AB-2 (#undef ALLOW_ADAMSBASHFORTH_3)
208      - not yet implemented with NH, CD_Scheme, pTracers, MNC_pickup ...
209    checkpoint57g_pre
210    
211    o make lambda[Theta,Salt]ClimRelax spatially varying
212      (default remains spatially uniform constant based on tau)
213    o added new control variables
214      * init. uVel, vVel, etanN
215      * lambda[Theta,Salt]ClimRelax
216    o separate masks used for ctrl_pack/unpack 'from write_grid' output
217      (suggested by G. Forget)
218    
219    checkpoint57f_post
220    o add parameter "baseTime" = model base time = time at iteration zero
221      new function DIFF_BASE_MULTIPLE (replace DIFFERENT_MULTIPLE) to
222      account for baseTime shift
223    o move Coriolis arrays from PARAMS.h to GRID.h
224    checkpoint57f_pre
225    
226    o mnc-ifying the seaice package
227    o introduced an alternative length scale calculation for use in the limiting
228      maximum viscosity (off by default, see mom_vi_hdissip.F for details)
229    o S/R ptracers_calc_diff: argument list bug for CALL KPP_CALC_DIFF_S
230    o added modified Leith scheme with viscosity proportional to grad(Hdiv)
231      as well as grad(vort3).  Made it compatible with both approximate form
232      for the cubed sphere and full form of these gradients.  Added flag
233      useFullLeith to select between approximate and full form.  
234    o add "d0" in getcon.F to reduce differences between compilers/platforms
235      update output.txt of exp. fizhi-gridalt-hs
236    o change port_rand funtion to allow to set the seed.
237    o fix obscure MNC bug involving conversion between reals and integers
238      - it caused no problems with certain (eg. gcc, ifc) compilers but the
239        new version is now more standards-compliant
240    o adjoint-related modifications
241      * gad_dst3_adv_?: to be able to use advscheme=30 in adjoint
242      * gad_calc_rhs: fool adjoint, revert to advscheme=30 in reverse when using 33
243      * mom_vi_hdissip: to be able to use Leith scheme in adjoint
244    
245    checkpoint57e_post
246    o Adding eddy stress controls a la Ferreira et al.
247    checkpoint57e_pre (actually was tagged: eckpoint57e_pre)
248    
249    o fizhi pkg: fix AtoC and CtoA when called with same input & output array
250      update output.txt of exp. fizhi-gridalt-hs
251    o add more "Z" dimensions and associated coordinate vars to MNC
252    o pkg/exf: added twoDigitYear capability for option useExfYearlyFields
253    o parameter calendarDumps: when set, approximate months (30-31 days) and years
254      (360-372 days) for parameters chkPtFreq, pChkPtFreq, taveFreq, SEAICE_taveFreq,
255      KPP_taveFreq, and freq in pkg/diagnostics are converted to exact calendar
256      months and years.  Requires pkg/cal.
257    o diagnostics: add pickup functionality
258      - off by default for backwards compatibility
259      - current version only uses MDSIO -- MNC will be added
260    o allow to use pkg diagnostics for LAND pkg output & Shapiro Tendencies.
261    o pkg/shap_filt: fix for multi-tiles per face (CS-grid with EXCH2)
262    
263    checkpoint57d_post
264    o pkg/thsice used in the ocean: fix tile Pb related to sIceLoad forcing
265    o modify verification/ideal_2D_oce so that it tests the creation of mnc
266      output from the diagnostics package
267    o temporary fix in EXCH2_UV: add a 3rd call to fix the 24.tiles CS-grid set-up
268    o make genmake2 more portable by using ".$FS" instead of ".f" for more
269      of the test compilations (eg. IBM xlf on Mac OSX w/HFS filesys)
270    o add coordinate variables to the MNC output from the diagnostics package
271    o change MNC-flags default value: true when useMNC=TRUE
272    o add a "readgrid_mnc" flag to MNC and give model/src/ini_curvilinear_grid.F
273      the ability (off by default) to read the grid information using MNC
274    o lab_sea: use LSR_ERROR=1.E-12 for testing ; update output.txt
275    o diagnostics: fix a bug (sub-set of levels); keep full precision when averaging
276    o do snap-shot diagnostics at the middle of the time-interval (instead of
277      at the end).
278    o update exp. aim.5l_cs (use default LAND_OPTIONS.h file) and add
279      new test for AIM with thSIce + slab-ocean
280    o cpl_aim+ocn test: update output (optfile & default GMREDI_OPTIONS.h)
281    o move state variable diagnostics to the beginning of the time step ;
282      (note: still needs some work specially for snap-shot diagnostics)
283      duplicate & replace UVELVVEL diagnostics with UV_VEL_C & UV_VEL_Z
284    
285    checkpoint57c_post
286    o Change testing option (-ieee) to get closer agreement between g77 & ifort
287    o generate new output.txt files on faulks with g77 & the new -ieee option
288    checkpoint57c_pre
289    
290    o add "_d 0" in freeze ; change some "FLOAT" to "DFLOAT" and went back (TAF);
291      update output.txt of exp. global_ocean.90x40x15
292    o fix in ini_eos.F (one "_d 0" was missing): now g77 & ifc give much closer
293      results; update global_ocean_pressure & global_ocean.cs32x15 output.txt
294    o add saltFlux(+File) forcing capability with periodicExternalForcing
295    o allow to use pkg diagnostics for GM-Redi & ThSIce output
296    o diagnostics_fill: fill in up to sNx+1 or sNy+1 (if U,V or Z pt) for mnc.
297    o improvements for the MNC output from DIAGNOSTICS:
298      - correct handling of the unlimitied dimension
299      - all dims now have associated coordinate variables
300      - variables located at U, V, and Corner ("Z") points are now written
301        with the correct horzontal dimensions (eg. 'Xp1', 'Yp1') so that
302        *all* data points are output
303    o added seaice_summary.F and removed obsolete ALLOW_SEAICE's from pkg/seaice
304    o added pkg/seaice/seaice_monitor.F
305    o mdsio_readfield.F can now read files visible only to master MPI process.
306    o pkg/seaice: some test code for ice-modified ocean stress
307    o exf_getffields interpolation defaults to bilinear for all scalar forcing
308      fields (remains bicubic for wind velocity and stress).  This avoids, e.g.,
309      spurious negative numbers for precipitation and humidity.  Will cause
310      some small numerical differences for integrations using pkg/exf/exf_interp.F.
311    o pkg/ctrl/
312      * Add ctrlvec diagnostics in pack/unpack for nondimensional I/O
313        May be enabled via doPackDiag
314      *  introduce z-scaling of
315         + gradient (doZscalePack) and
316         + control (doZscaleUnpack)
317    o pkg/mdsio/
318      * enable useSingleCpuIO for state estimation (ctrl_pack/unpack) mdsio_gl.F
319      * N.B.: leave tiled I/O for tapelev (i.e. mds...vector)
320    
321    checkpoint57b_post
322    o simplify options in diagnostics_fill arguments (remove weird combinations)
323    o fix MNC coordinate variables so that they now contain per-face index
324      values (instead of xC,xG,yC,yG values) when run with EXCH2 since, in
325      general, EXCH2 grids are only aligned to a "local" coordinate system
326    o test diagnostics pkg in dic_example (no output) and ideal_2D_oce (with ouput)
327    o Implement instantaneous output within pkg diagnostics:
328      setting a negative frequency in data.diagnostics produces
329     "snap-shot" output (as opposed to time-average if freq > 0)
330    o move out off EQUIVALENCE all diagnostics that fizhi does not use ;
331      NOTE: change ptracer diagnostics name: use 2 characters to work with
332            more than 9 tracers. Add also diagnostics of advect & diffus flux.
333    o more CF compliance: convert all MNC 'iter' variables to 'T' so that it
334      becomes the coordinate variable for the 'T' dimension
335    o add CF-style coordinate variables to MNC
336      - just a first cut:  numbers are meaningless on the cubesphere and
337        missing along the T axis but otherwise it works!
338    o add surface flux diagnostics: TAUX, TAUY, TFLUX, TRELAX, TICE, SFLUX, SRELAX
339    o pkg/thSIce: read initial state from 6 files ; allow monitor to use MNC.
340    o add diagnostics of advective & diffusive flux for T & S (pTracers coming soon)
341      this is based directly on what the model compute, so that the content of
342      each diagnostics might be affected by switching options (e.g., implicitDiffusion)
343    o small changes for diagnostics (gad_biharm_?.F, arguments of S/R impldiff.F)
344    o clean up build options files for SunOS, in particular
345      - remove -traditional from xmakedepend
346      - change -xarch=v9 to -xarch=native for f77
347      - restore use of make (not gmake)
348      - add CC=gcc if using g77
349    o changes per discussion of AM, JMC, & EH3 today:
350      - move redundant "grid" variables out of "state" -- in preparation of
351        creating proper CF-style coordinate variables and in recognition
352        that any/all grid variables can be easily copied (eg. w/NCO) from
353        the grid files into any of the other NetCDF files
354      - *always* output grid variables with MDSIO (this will eventually be
355        changed)
356      - output MNC grid file if useMNC is true
357    o every instance of _END_MASTER() has been found and replaced with
358      _END_MASTER( myThid ) in order to satisfy certain picky Sun
359      preprocessors
360    o re-arrange diagnostics pkg initialisation:
361     - allow each package to extend the available diagnostics list
362     - add some checking and fix small problems (multi-threaded, ...)
363     - new S/R diagnostics_fill (replace fill_diagnostics):
364       look through the short list of active diag. (instead of the long list)
365       create function DIAGNOSTICS_IS_ON to tell if a diagnostics is active
366    
367    checkpoint57a_post
368    o this set of changes restores TAMC compatibility
369      tested for global_ocean.90x40x15 adjoint on trough
370      (what a pain)
371    
372    checkpoint57a_pre
373    o some modifs in tools/build_options for sunos
374    o call ctrl_pack for ctrl at end for optimcycle=0
375    
376    checkpoint57
377    o add horizontal bi-harmonic viscosity for vertical velocity
378      - new parameter viscA4W (defaults to viscA4)
379      - affects only non-hydrostatic code
380      - to be done: no-slip lateral boundary conditions
381    o switch back to "sflux = sflux - runoff" in exf_getforcing.F
382    o implement Implicit Vertical advection for pTracers
383    o depth convergence accelerator: replace deltaTtracer by dTtracerLev(k)
384      (implemented also for implicit vertical diffusion & advection)
385    o OBCS: extend application of tracer open boundary conditions
386      to a strip beyond the boundary of width Olx/Oly
387    o add call monitor to TAF set of required calls (flow directives)
388      and include in natl_box_adjoint
389    o untangle a few ifdefs related to cost, ctrl, autodiff
390      untangel a few ALLOW_ECCO_OPTIMIZATION
391    o Apply Cooper & Haines representative estimates also at sub-surface (k=Nr)
392      (theta2, salt2 in ecco_cost_weights)
393    
394    checkpoint56c_post
395    o OBCS as control variables
396      - update ctrl_ad_diff.list, obcs_ad_diff.list
397      - remove balance of obcs controls from default
398      - fix index bug nobcs in ctrl_init
399      - fix dummy fields filen in ctrl_pack
400      - add dummy weights for obcs
401    o lsopt: comment out fort.94 output
402    o optim:
403      - remove unnecessary header files
404      - adjusted namelists
405      - add xerbla.F to Makefile
406    o exf:
407      - multiple modifications of exf_check_range
408      - unit change in exf_init_runoff from [m/year] to [m/s]
409    o mdsio:
410      - i/o-vector change debugLevel from debLevA to debLevB
411    
412    checkpoint56b_post
413    o collect all ptracers output in an new routine (PTRACERS_OUTPUT) that
414      is called from DO_THE_MODEL_IO
415      - rename PTRACERS_STATV_WRITE to PTRACERS_WRITE_TIMEAVE
416      - introduce new parameter PTRACERS_dumpFreq (defaults to dumpFreq)
417      - clean up PTRACERS_WRITE_TIMEAVE a little
418    o add another verification experiment that tests both the cfc-pkg and
419      the gchem-pkg with GCHEM_SEPARATE_FORCING undefined, that is with
420      reactive tendencies treated inline with regular timestepping
421    o testreport previously did a lousy job of comparing small numbers, so
422      we (Ed and Martin) changed the  way the cut-off of 1.e-12 is
423      implemented in the little c-progam tmp_cmpnum.c which is embedded in
424      testreport.
425    o ptracers_monitor: bug fix for MPI
426    
427    checkpoint56a_post
428    o GCHEM: finish reorganizating the package
429      - forward_step calls GCHEM_CALC_TENDENDY, which computes gchemTendency
430        (introduces another 3D-array for each passive tracer, but only if
431        GCHEM_SEPARATE_FORCING is undefined. For GCHEM_SEPARATE_FORCING
432        gchemTendency is not needed because the timestep is done separately)
433      - gchemTendency is added to gPtr in GCHEM_ADD_TENDENCY
434      - GCHEM is now---more or less cleanly---separate from PTRACERS
435      - to bo done: handling of surfaceForcingPtr that is needed for KPP not
436        so clear to me how that should be done in a general way.
437    o CFC: improve formatting of output in CFC_ATMOS
438    o PTRACERS:
439      - rename GCHEM_MONITOR to PTRACERS_MONITOR and call it from MONITOR, so
440        that ALL experiments with ptracers enable can be checked. This makes
441        GCHEM_MONITOR obsolete.
442      - include a runtime parameter PTRACERS_monitorFreq that defaults to
443        monitorFreq
444      - set default PTRACERS_write_mdsio to false if PTRACERS_write_mnc is true
445    o add PTRACERS (PTR0[1-5]) to testreport output
446    o exf_check_range:
447      * default changed to .TRUE.
448      * will check values for niter0 if debLevA, every timestep if debLevB
449      * STOP in exf_check_range if 'out of range'
450      * range chosen generous to allow for potential extema
451      TBD: a version with stricter range
452           permitted range would be runtime parameters
453  o GMredi:  o GMredi:
454    - fix ldd97 slope limit ; extend valid domain of Psi-Bolus ;    - fix ldd97 slope limit ; extend valid domain of Psi-Bolus ;
455    - 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.
# Line 11  o GCHEM: Line 458  o GCHEM:

460    - introduced a useGCHEM runtime flag and applied it everywhere.    - introduced a useGCHEM runtime flag and applied it everywhere.
461      - renamed PTRACERS_SEPARATE_FORCING to GCHEM_SEPARATE_FORCING;
462        this flag is now only visible within GCHEM-pkg routines.
463      - moved gchem_forcing_int temporarily into ptracers_forcing, this will
464        be replaced by a 3D array that is computed before thermodynamics; for
465        this, the tracer ID iTracer had to be included into the parameter list
466        of ptracers_forcing
467      - set up forward_step to call gchem_forcing, that will replace
468        gchem_forcing_int in ptracers_forcing
469      - cleaning up
470  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
