6    
7    checkpoint57r_post
8    o make MNC variable initialization happen earlier
9    o add diagnostics for (almost) each term of the momentum Eq.
10    o remove SST,SSS,UVEL_k2,VVEL_k2 diagnostics.
11    o move pkg timeave out of pkg-groups "oceanic" & "atmospheric" (pkg/pkg_groups)
12    o remove MINIMAL_TAVE_OUTPUT option ;
13      add "dumpInitAndLast" to replace "nodumps" (and MINIMAL_TAVE_OUTPUT).
14    o move some basic S/R (used elsewhere in the code) from pkg/mdsio to eesupp/src
15      allows to compile without pkg/mdsio (& test successfully hs94.1x64x5)
16    o add MNC output for adjoint of EXF (adexf), SEAICE (adseaice)
17    o add time-dependent SST, SSS control
18    o cost terms in ecco/ modularized (new cost_generic.F)
19    o cost_averages routines are modularized (new cost_averagesgeneric.F)
20    o new infrastructure for seaice model vs. obs misfits in seaice/
21      * driver from the_main_loop.F is seaice_cost_driver.F
22      * first term is AREA vs. SMR observation misfit (ALLOW_SEAICE_COST_SMR_AREA)
23      * gradient check in Exp. 6a of natl_box_adjoint/
24    o natl_box_adjoint input_seaice for Lab. Sea now available online via wget
25      (see README file)
26    
27    checkpoint57q_post
28    o fix initialisation Pb in calc_gw (get NANs in exp5 with g77)
29    o fix annoying months-old bug in mnc/mdsio output for seaice pkg
30      - bug was reported by Jean-Michel and Ian Fenty
31    o fix initialization Pb in AIM-Ocean coupled model (aim_sice2aim.F)
32      update exp. cpl_aim+ocn output.
33    o Implement 4-level checkpointing: AUTODIFF_4_LEVEL_CHECKPOINT
34      Needed for high-res. runs with large global files
35      to be able to limit tapelev size
36    o Changed some tests for adjoint:
37      * carbon/ now tests AUTODIFF_2_LEVEL_CHECKPOINT
38      * natl_box_adjoint/code_bulk/ tests AUTODIFF_4_LEVEL_CHECKPOINT
39      * global_ocean.90x40x15/ back to default 3-level checkpointing
40    o Modifications to enable scripted COMMON to MODULE conversion
41      * verification/OpenAD/code/ has necessary scripts and description;
42      * converts, compiles and runs successfully;
43    
44    checkpoint57p_post
45    o reading of delXfile & delYfile moved from ini_parms.F to ini_grid.F
46    o move ${PKG}_MNC_INIT from ${PKG}_READ_PARAMS to ${PKG}_INIT_FIXED
47      (already the case for some pkgs, including recent MNC_init, e.g. thsice)
48    o call CALC_GW from DYNAMICS (instead of from FORWARD_STEP)
49    o Dissipation & phiHyd gradient are always added to gU,gV in timestep.F
50      (was already the case for dissipation with mom_vecinv,
51       and also the case for grad.PhiHyd when staggered-timeStep)
52      This will allow to put dissipation out-off the AB time-stepping.
53     Unfortunately, affects truncation error. Update output of exp. that "fails"
54      (cg2d matching number) and leave the others for later: front_relax(10),
55      global_ocean_pressure(10),ideal_2D_oce(10),internal_wave(9),lab_sea(12),
56      matrix_example(7!),natl_box(12),plume_on_slope(11),vermix(12x3,11x2).
57    
58    checkpoint57o_post
59    o fix MNC/MDSIO flags in PTRACERS so that (1) it works, and
60      (2) its ready to be documented during the 20050801 DocFest
61    o MNC-ify the gmredi package -- tested and works w/ and w/o mnc
62      for ideal_2D_oce and lab_sea on linux_ia32_g77
63    o set to #undef CTRL_SET_OLD_MAXCVARS_30
64      in global1x1_tot/code_seaice_adj to access indices 32, 33
65      (worth another tag)
66    
67    checkpoint57n_post
68    o adding precip control xx_precip 32
69    o adding swflux control xx_swflux 33
70    o Replacing 10 forcing penalty cost routines by 1 generic.
71    o Implementing partitioning in time-mean and variable adjustment
72      for atmos. state.
73    o Time-mean constant error is now read in data.ecco (instead of hard-coded)
74    o in natl_box_adjoint:
75      * updated exp 1 to 10
76        (but does not have time-mean vs. variable split results yet)
77    o updated global1x1/*_seaice_adj/
78      to incorporate latest changes
79    o enable useSingleCpuIO for mdsio vector routines
80      (applies in particular to tapelev I/O)
81    o removed inefficient K-loop in all active_file*control*.F
82    
83    checkpoint57m_post
84    o re-arrange exp. adjustment.cs-32x32x1 (adjust_nlfs.cs-32x32x1 merge into)
85      and advect_cs (use EXCH-2 and standard cs-32 grid files).
86    o pkg/exch2: filling of face-corner halo regions is optional
87      (ifdef W2_FILL_NULL_REGIONS) and is turned off by default.
88    
89    checkpoint57l_post
90     tag before updating tutorials (pre-release-2)
91    o add cos & sin of grid-direction orientation angle (curvilinear grid only,
92       for output and interpolation of input fields onto model grid)
93    o fix radius in mom_v_metric_cylinder.F (wrong by dy/2).
94       Affects results of exp. rotating_tank ; update output.txt.
95    o pkg/diagnostics: 2 new S/R to fill a diagnostics using a scaling factor
96          and taking the square quantity and/or using a fraction-weight field.
97    o fix aim_diagnostics_init.F mate numbers.
98    o add mnc output capability to diagnostics/diagstat and update
99      our cvsignore files for the ACSII output generated
100

103      new EXF diagnostics output.
104    
105    checkpoint57j_post
106    o exf
107      * bug fix in exf_bulkformulae for psimh (spotted by Eliyahu Biton):
108        Bracket missing in eqn. for psimh (eqn. 7 of Large & Pond, 1982);
109        terms -2*ATAN(x) + pi/2 were added to both stable and unstable case.
110      * extended diagnostics output
111        - now includes all EXF variables
112        - hs, hl moved to common block
113        - separate S/R for diagnostics, called after ctrl vector is added
114        - name changed for EXFsw -> EXFswnet, EXFlw -> EXFlwnet
115        - EXFqnet contains true Qnet (i.e. includes qsw)
116      * updated verif. lab_sea, global_with_exf
117      * Rearranging hflux (exf_mapfields -> exf_getforcing)
118        to ensure that diagnostics sees a true EXFqnet
119    o add matlab scripts for CS-grid vectors (in utils/cs_grid)
120    o diagnostics pkg: change pointers so that 1 diagnostic can be used
121      several times with different frequencies.
122    o mnc-ify the thsice package as requested by Daniel Enderton
123      - the monitor--MNC output needs work
124      - many attributes need to be added (most are currently blank)
125    o mnc-ify theaim_v23 package as requested by Daniel Enderton
126      - many attributes need to be added (most are currently blank)

129    o fix bug in rStar code (calc_r_star.F) when used with topo/bathy.
130      update output.txt from: aim.5l_cs (& .thSI), cpl_aim+ocn,
131         fizhi-gridalt-hs and global_ocean.cs32x15 (& .thsice).
132    o fix few little things to avoid floating error with -ftrapuv (ifort v9)
133     (ini_spherical_polar_grid.F, calc_r_star.F, monitor/mon_surfcor.F)
134    
135    checkpoint57i_post
136    o Diagnostics package was changed: diagnostic allocation is now deactivated
137      by setting an empty file name in the namelist (used to be by setting 0 frequency)
138    o momentum advection (VI form) options: activate 4th.O vorticity Coriolis ;
139      add 1rst Order upwind vertical Shear.
140    o add a quick fix for A/B checkpointing in OFFLINE mode
141    o add IGNORE_TIME define and -ignore_time option to genmake2 as an
142      end-run around the C/Fortran linking horror in eesup/src/timers.F
143    o added pkg/runclock: allows user to terminate run based on wall clock
144    o added non-hydrostatic scaling parameter: nh_am2
145    o pkg/my82: futile attempt to make results compiler-independent by adding
146      some "_d 0", etc. no effect.
147    o for mnc output, fill the 'T' coordinate var with myTime and create a
148      separate 'iter' variable for iteration count
149    o pkg/diagnostics:
150      add new capability: output of Global/Regional & per-level statistics ;
151      tested against monitor output (including land & thSIce) on various exp.
152    o make seaice-pkg I/O type flags (MNC/MDS) more standard.
153    
154    checkpoint57h_done
155      tag after changing user customized files (DIAGNOSTICS_SIZE.h,

157    
158    o pkg/diagnostics: prepare for Global/Regional statistics.
159      add 2nd namelist in data.diagnostics and update DIAGNOSTICS_SIZE.h
160    o remove "baseTime" (no used) from arg. list of DIFF_BASE_MULTIPLE
161      and rename it: DIFFERENT_MULTIPLE
162    
163    checkpoint57h_post
164    o move tIter0 from data.gchem to PTRACERS_Iter0 in data.ptracers
165    o pkg/diagnostics: change output frequency, now in seconds (instead
166      of Nb of iterations). This requires to change data.diagnostics.
167    checkpoint57h_pre
168    
169    o in mnc, let the user create the output dir if both mnc_outdir_date
170      and mnc_outdir_num are false
171    o add fflags() to pkg/diagnostics which allows one to specify, on a
172      per-file basis, the file precision [default behavior is unchanged]
173    o added diagnostics to pkg/kpp, including computation of mixed layer
174      depth based on a temperature/density criterion
175    o updated verification/natl_box to test the new pkg/kpp diagnostics
176    o bugs fixed (with useAbsVorticity=T & with useJamartMomAdv=T)
177    o test AB-3 code with 4th.Order advection scheme (advect_xy/input.ab3_c4)
178    o fix mnc flags in pkg/seaice so that they are "owned" by seaice,
179      not mnc -- this mistake was found by JMC and is now corrected
180    
181    checkpoint57g_post
182    o add Adams-Bashforth 3rd Order time stepping:
183      - default remains AB-2 (#undef ALLOW_ADAMSBASHFORTH_3)
184      - not yet implemented with NH, CD_Scheme, pTracers, MNC_pickup ...
185    checkpoint57g_pre
186    
187    o make lambda[Theta,Salt]ClimRelax spatially varying
188      (default remains spatially uniform constant based on tau)
189    o added new control variables
190      * init. uVel, vVel, etanN
191      * lambda[Theta,Salt]ClimRelax
192    o separate masks used for ctrl_pack/unpack 'from write_grid' output
193      (suggested by G. Forget)
194    
195    checkpoint57f_post
196    o add parameter "baseTime" = model base time = time at iteration zero
197      new function DIFF_BASE_MULTIPLE (replace DIFFERENT_MULTIPLE) to
198      account for baseTime shift
199    o move Coriolis arrays from PARAMS.h to GRID.h
200    checkpoint57f_pre
201    
202    o mnc-ifying the seaice package

204      maximum viscosity (off by default, see mom_vi_hdissip.F for details)
205    o S/R ptracers_calc_diff: argument list bug for CALL KPP_CALC_DIFF_S
206    o added modified Leith scheme with viscosity proportional to grad(Hdiv)
207      as well as grad(vort3).  Made it compatible with both approximate form
208      for the cubed sphere and full form of these gradients.  Added flag
209      useFullLeith to select between approximate and full form.  
210    o add "d0" in getcon.F to reduce differences between compilers/platforms
211      update output.txt of exp. fizhi-gridalt-hs
212    o change port_rand funtion to allow to set the seed.
213    o fix obscure MNC bug involving conversion between reals and integers
214      - it caused no problems with certain (eg. gcc, ifc) compilers but the
215        new version is now more standards-compliant
216    o adjoint-related modifications
217      * gad_dst3_adv_?: to be able to use advscheme=30 in adjoint
218      * gad_calc_rhs: fool adjoint, revert to advscheme=30 in reverse when using 33
219      * mom_vi_hdissip: to be able to use Leith scheme in adjoint
220    
221    checkpoint57e_post
222    o Adding eddy stress controls a la Ferreira et al.
223    checkpoint57e_pre (actually was tagged: eckpoint57e_pre)
224    
225    o fizhi pkg: fix AtoC and CtoA when called with same input & output array
226      update output.txt of exp. fizhi-gridalt-hs
227    o add more "Z" dimensions and associated coordinate vars to MNC
228    o pkg/exf: added twoDigitYear capability for option useExfYearlyFields
229    o parameter calendarDumps: when set, approximate months (30-31 days) and years
230      (360-372 days) for parameters chkPtFreq, pChkPtFreq, taveFreq, SEAICE_taveFreq,
231      KPP_taveFreq, and freq in pkg/diagnostics are converted to exact calendar
232      months and years.  Requires pkg/cal.
233    o diagnostics: add pickup functionality
234      - off by default for backwards compatibility
235      - current version only uses MDSIO -- MNC will be added
236    o allow to use pkg diagnostics for LAND pkg output & Shapiro Tendencies.
237    o pkg/shap_filt: fix for multi-tiles per face (CS-grid with EXCH2)
238

240    o pkg/thsice used in the ocean: fix tile Pb related to sIceLoad forcing
241    o modify verification/ideal_2D_oce so that it tests the creation of mnc
242      output from the diagnostics package
243    o temporary fix in EXCH2_UV: add a 3rd call to fix the 24.tiles CS-grid set-up
244  o make genmake2 more portable by using ".$FS" instead of ".f" for more  o make genmake2 more portable by using ".$FS" instead of ".f" for more
