5      ==============================      ==============================
6    
7    o  diagnostics "VISCAHD" & "VISCA4D" replace "VISCAH" & "VISCA4".
8    o In response to JMC's bug report, genmake2 now ignores any soft-links
9      that it finds in the *current* directory when searching for files.
10      Soft-links found in any other source directories will still work as
11      they did before.
12    o add HAVE_SETRLSTK define and useSETRLSTK flag (eedata) which calls
13      a C routine to unlimit the stack size
14    o mnc-ify pkg/aim snapshot vars
15    o mnc-ify pkg/land as requested by Daniel
16    o various changes to mnc including:
17      - all files use the new "BASENAME[[.ITER].{t|f}NUM].nc" format
18      - output can now be grouped so that all files within a group
19          change the ITER portion of their names in lock-step together
20      - can now read ("global") PER-FACE (in addition to PER-TILE) files
21          and works with both EXCH1 and EXCH2 (but needs more testing)
22      - writing works for all verification test cases w/ g77 on Linux
23    
24    checkpoint57r_post
25    o make MNC variable initialization happen earlier
26    o add diagnostics for (almost) each term of the momentum Eq.
27    o remove SST,SSS,UVEL_k2,VVEL_k2 diagnostics.
28    o move pkg timeave out of pkg-groups "oceanic" & "atmospheric" (pkg/pkg_groups)
29    o remove MINIMAL_TAVE_OUTPUT option ;
30      add "dumpInitAndLast" to replace "nodumps" (and MINIMAL_TAVE_OUTPUT).
31    o move some basic S/R (used elsewhere in the code) from pkg/mdsio to eesupp/src
32      allows to compile without pkg/mdsio (& test successfully hs94.1x64x5)
33    o add MNC output for adjoint of EXF (adexf), SEAICE (adseaice)
34    o add time-dependent SST, SSS control
35    o cost terms in ecco/ modularized (new cost_generic.F)
36    o cost_averages routines are modularized (new cost_averagesgeneric.F)
37    o new infrastructure for seaice model vs. obs misfits in seaice/
38      * driver from the_main_loop.F is seaice_cost_driver.F
39      * first term is AREA vs. SMR observation misfit (ALLOW_SEAICE_COST_SMR_AREA)
40      * gradient check in Exp. 6a of natl_box_adjoint/
41    o natl_box_adjoint input_seaice for Lab. Sea now available online via wget
42      (see README file)
43    
44    checkpoint57q_post
45    o fix initialisation Pb in calc_gw (get NANs in exp5 with g77)
46    o fix annoying months-old bug in mnc/mdsio output for seaice pkg
47      - bug was reported by Jean-Michel and Ian Fenty
48    o fix initialization Pb in AIM-Ocean coupled model (aim_sice2aim.F)
49      update exp. cpl_aim+ocn output.
50    o Implement 4-level checkpointing: AUTODIFF_4_LEVEL_CHECKPOINT
51      Needed for high-res. runs with large global files
52      to be able to limit tapelev size
53    o Changed some tests for adjoint:
54      * carbon/ now tests AUTODIFF_2_LEVEL_CHECKPOINT
55      * natl_box_adjoint/code_bulk/ tests AUTODIFF_4_LEVEL_CHECKPOINT
56      * global_ocean.90x40x15/ back to default 3-level checkpointing
57    o Modifications to enable scripted COMMON to MODULE conversion
58      * verification/OpenAD/code/ has necessary scripts and description;
59      * converts, compiles and runs successfully;
60    
61    checkpoint57p_post
62    o reading of delXfile & delYfile moved from ini_parms.F to ini_grid.F
63    o move ${PKG}_MNC_INIT from ${PKG}_READ_PARAMS to ${PKG}_INIT_FIXED
64      (already the case for some pkgs, including recent MNC_init, e.g. thsice)
65    o call CALC_GW from DYNAMICS (instead of from FORWARD_STEP)
66    o Dissipation & phiHyd gradient are always added to gU,gV in timestep.F
67      (was already the case for dissipation with mom_vecinv,
68       and also the case for grad.PhiHyd when staggered-timeStep)
69      This will allow to put dissipation out-off the AB time-stepping.
70     Unfortunately, affects truncation error. Update output of exp. that "fails"
71      (cg2d matching number) and leave the others for later: front_relax(10),
72      global_ocean_pressure(10),ideal_2D_oce(10),internal_wave(9),lab_sea(12),
73      matrix_example(7!),natl_box(12),plume_on_slope(11),vermix(12x3,11x2).
74    
75    checkpoint57o_post
76    o fix MNC/MDSIO flags in PTRACERS so that (1) it works, and
77      (2) its ready to be documented during the 20050801 DocFest
78    o MNC-ify the gmredi package -- tested and works w/ and w/o mnc
79      for ideal_2D_oce and lab_sea on linux_ia32_g77
80    o set to #undef CTRL_SET_OLD_MAXCVARS_30
81      in global1x1_tot/code_seaice_adj to access indices 32, 33
82      (worth another tag)
83    
84    checkpoint57n_post
85    o adding precip control xx_precip 32
86    o adding swflux control xx_swflux 33
87    o Replacing 10 forcing penalty cost routines by 1 generic.
88    o Implementing partitioning in time-mean and variable adjustment
89      for atmos. state.
90    o Time-mean constant error is now read in data.ecco (instead of hard-coded)
91    o in natl_box_adjoint:
92      * updated exp 1 to 10
93        (but does not have time-mean vs. variable split results yet)
94    o updated global1x1/*_seaice_adj/
95      to incorporate latest changes
96    o enable useSingleCpuIO for mdsio vector routines
97      (applies in particular to tapelev I/O)
98    o removed inefficient K-loop in all active_file*control*.F
99    
100    checkpoint57m_post
101    o re-arrange exp. adjustment.cs-32x32x1 (adjust_nlfs.cs-32x32x1 merge into)
102      and advect_cs (use EXCH-2 and standard cs-32 grid files).
103    o pkg/exch2: filling of face-corner halo regions is optional
104      (ifdef W2_FILL_NULL_REGIONS) and is turned off by default.
105    
106    checkpoint57l_post
107     tag before updating tutorials (pre-release-2)
108    o add cos & sin of grid-direction orientation angle (curvilinear grid only,
109       for output and interpolation of input fields onto model grid)
110    o fix radius in mom_v_metric_cylinder.F (wrong by dy/2).
111       Affects results of exp. rotating_tank ; update output.txt.
112    o pkg/diagnostics: 2 new S/R to fill a diagnostics using a scaling factor
113          and taking the square quantity and/or using a fraction-weight field.
114    o fix aim_diagnostics_init.F mate numbers.

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

147      update output.txt from: aim.5l_cs (& .thSI), cpl_aim+ocn,
148         fizhi-gridalt-hs and global_ocean.cs32x15 (& .thsice).
149    o fix few little things to avoid floating error with -ftrapuv (ifort v9)
150     (ini_spherical_polar_grid.F, calc_r_star.F, monitor/mon_surfcor.F)
151    
152    checkpoint57i_post
153    o Diagnostics package was changed: diagnostic allocation is now deactivated
154      by setting an empty file name in the namelist (used to be by setting 0 frequency)
155    o momentum advection (VI form) options: activate 4th.O vorticity Coriolis ;
156      add 1rst Order upwind vertical Shear.
157    o add a quick fix for A/B checkpointing in OFFLINE mode
158    o add IGNORE_TIME define and -ignore_time option to genmake2 as an
159      end-run around the C/Fortran linking horror in eesup/src/timers.F
160    o added pkg/runclock: allows user to terminate run based on wall clock
161    o added non-hydrostatic scaling parameter: nh_am2
162    o pkg/my82: futile attempt to make results compiler-independent by adding
163      some "_d 0", etc. no effect.
164    o for mnc output, fill the 'T' coordinate var with myTime and create a
165      separate 'iter' variable for iteration count
166    o pkg/diagnostics:
167      add new capability: output of Global/Regional & per-level statistics ;
168      tested against monitor output (including land & thSIce) on various exp.
169    o make seaice-pkg I/O type flags (MNC/MDS) more standard.
170    
171    checkpoint57h_done
172      tag after changing user customized files (DIAGNOSTICS_SIZE.h,

174    
175    o pkg/diagnostics: prepare for Global/Regional statistics.
176      add 2nd namelist in data.diagnostics and update DIAGNOSTICS_SIZE.h
177    o remove "baseTime" (no used) from arg. list of DIFF_BASE_MULTIPLE
178      and rename it: DIFFERENT_MULTIPLE
179    
180    checkpoint57h_post
181    o move tIter0 from data.gchem to PTRACERS_Iter0 in data.ptracers
182    o pkg/diagnostics: change output frequency, now in seconds (instead
183      of Nb of iterations). This requires to change data.diagnostics.
184    checkpoint57h_pre
185    
186    o in mnc, let the user create the output dir if both mnc_outdir_date
187      and mnc_outdir_num are false
188    o add fflags() to pkg/diagnostics which allows one to specify, on a
189      per-file basis, the file precision [default behavior is unchanged]
190    o added diagnostics to pkg/kpp, including computation of mixed layer
191      depth based on a temperature/density criterion
192    o updated verification/natl_box to test the new pkg/kpp diagnostics
193    o bugs fixed (with useAbsVorticity=T & with useJamartMomAdv=T)
194    o test AB-3 code with 4th.Order advection scheme (advect_xy/input.ab3_c4)
195    o fix mnc flags in pkg/seaice so that they are "owned" by seaice,
196      not mnc -- this mistake was found by JMC and is now corrected
197    
198    checkpoint57g_post
199    o add Adams-Bashforth 3rd Order time stepping:
200      - default remains AB-2 (#undef ALLOW_ADAMSBASHFORTH_3)
201      - not yet implemented with NH, CD_Scheme, pTracers, MNC_pickup ...
202    checkpoint57g_pre
203    
204    o make lambda[Theta,Salt]ClimRelax spatially varying
205      (default remains spatially uniform constant based on tau)
206    o added new control variables
207      * init. uVel, vVel, etanN
208      * lambda[Theta,Salt]ClimRelax
209    o separate masks used for ctrl_pack/unpack 'from write_grid' output
210      (suggested by G. Forget)
211    
212    checkpoint57f_post
213    o add parameter "baseTime" = model base time = time at iteration zero
214      new function DIFF_BASE_MULTIPLE (replace DIFFERENT_MULTIPLE) to
215      account for baseTime shift
216    o move Coriolis arrays from PARAMS.h to GRID.h
217    checkpoint57f_pre
218    
219    o mnc-ifying the seaice package

221      maximum viscosity (off by default, see mom_vi_hdissip.F for details)
222    o S/R ptracers_calc_diff: argument list bug for CALL KPP_CALC_DIFF_S
223    o added modified Leith scheme with viscosity proportional to grad(Hdiv)
224      as well as grad(vort3).  Made it compatible with both approximate form
225      for the cubed sphere and full form of these gradients.  Added flag
226      useFullLeith to select between approximate and full form.  
227    o add "d0" in getcon.F to reduce differences between compilers/platforms
228      update output.txt of exp. fizhi-gridalt-hs
229    o change port_rand funtion to allow to set the seed.
230    o fix obscure MNC bug involving conversion between reals and integers
231      - it caused no problems with certain (eg. gcc, ifc) compilers but the
232        new version is now more standards-compliant
233    o adjoint-related modifications
234      * gad_dst3_adv_?: to be able to use advscheme=30 in adjoint
235      * gad_calc_rhs: fool adjoint, revert to advscheme=30 in reverse when using 33
236      * mom_vi_hdissip: to be able to use Leith scheme in adjoint
237    
238    checkpoint57e_post
239    o Adding eddy stress controls a la Ferreira et al.
240    checkpoint57e_pre (actually was tagged: eckpoint57e_pre)
241    
242    o fizhi pkg: fix AtoC and CtoA when called with same input & output array
243      update output.txt of exp. fizhi-gridalt-hs
244    o add more "Z" dimensions and associated coordinate vars to MNC
245    o pkg/exf: added twoDigitYear capability for option useExfYearlyFields
246    o parameter calendarDumps: when set, approximate months (30-31 days) and years
247      (360-372 days) for parameters chkPtFreq, pChkPtFreq, taveFreq, SEAICE_taveFreq,
248      KPP_taveFreq, and freq in pkg/diagnostics are converted to exact calendar
249      months and years.  Requires pkg/cal.
250    o diagnostics: add pickup functionality
251      - off by default for backwards compatibility
252      - current version only uses MDSIO -- MNC will be added
253    o allow to use pkg diagnostics for LAND pkg output & Shapiro Tendencies.
254    o pkg/shap_filt: fix for multi-tiles per face (CS-grid with EXCH2)
255    
256    checkpoint57d_post
257    o pkg/thsice used in the ocean: fix tile Pb related to sIceLoad forcing
258    o modify verification/ideal_2D_oce so that it tests the creation of mnc
259      output from the diagnostics package
260    o temporary fix in EXCH2_UV: add a 3rd call to fix the 24.tiles CS-grid set-up
261    o make genmake2 more portable by using ".$FS" instead of ".f" for more
262      of the test compilations (eg. IBM xlf on Mac OSX w/HFS filesys)
263  o add coordinate variables to the MNC output from the diagnostics package  o add coordinate variables to the MNC output from the diagnostics package
264  o change MNC-flags default value: true when useMNC=TRUE  o change MNC-flags default value: true when useMNC=TRUE
