5      ==============================      ==============================
6    
7    o mnc-ify pkg/land as requested by Daniel
8    o various changes to mnc including:
9      - all files use the new "BASENAME[[.ITER].{t|f}NUM].nc" format
10      - output can now be grouped so that all files within a group
11          change the ITER portion of their names in lock-step together
12      - can now read ("global") PER-FACE (in addition to PER-TILE) files
13          and works with both EXCH1 and EXCH2 (but needs more testing)
14      - writing works for all verification test cases w/ g77 on Linux
15    
16    checkpoint57r_post
17    o make MNC variable initialization happen earlier
18    o add diagnostics for (almost) each term of the momentum Eq.
19    o remove SST,SSS,UVEL_k2,VVEL_k2 diagnostics.
20    o move pkg timeave out of pkg-groups "oceanic" & "atmospheric" (pkg/pkg_groups)
21    o remove MINIMAL_TAVE_OUTPUT option ;
22      add "dumpInitAndLast" to replace "nodumps" (and MINIMAL_TAVE_OUTPUT).
23    o move some basic S/R (used elsewhere in the code) from pkg/mdsio to eesupp/src
24      allows to compile without pkg/mdsio (& test successfully hs94.1x64x5)
25    o add MNC output for adjoint of EXF (adexf), SEAICE (adseaice)
26    o add time-dependent SST, SSS control
27    o cost terms in ecco/ modularized (new cost_generic.F)
28    o cost_averages routines are modularized (new cost_averagesgeneric.F)
29    o new infrastructure for seaice model vs. obs misfits in seaice/
30      * driver from the_main_loop.F is seaice_cost_driver.F
31      * first term is AREA vs. SMR observation misfit (ALLOW_SEAICE_COST_SMR_AREA)
32      * gradient check in Exp. 6a of natl_box_adjoint/
33    o natl_box_adjoint input_seaice for Lab. Sea now available online via wget
34      (see README file)
35    
36    checkpoint57q_post
37    o fix initialisation Pb in calc_gw (get NANs in exp5 with g77)
38    o fix annoying months-old bug in mnc/mdsio output for seaice pkg
39      - bug was reported by Jean-Michel and Ian Fenty
40    o fix initialization Pb in AIM-Ocean coupled model (aim_sice2aim.F)
41      update exp. cpl_aim+ocn output.
42    o Implement 4-level checkpointing: AUTODIFF_4_LEVEL_CHECKPOINT
43      Needed for high-res. runs with large global files
44      to be able to limit tapelev size
45    o Changed some tests for adjoint:
46      * carbon/ now tests AUTODIFF_2_LEVEL_CHECKPOINT
47      * natl_box_adjoint/code_bulk/ tests AUTODIFF_4_LEVEL_CHECKPOINT
48      * global_ocean.90x40x15/ back to default 3-level checkpointing
49    o Modifications to enable scripted COMMON to MODULE conversion
50      * verification/OpenAD/code/ has necessary scripts and description;
51      * converts, compiles and runs successfully;
52    
53    checkpoint57p_post
54    o reading of delXfile & delYfile moved from ini_parms.F to ini_grid.F
55    o move ${PKG}_MNC_INIT from ${PKG}_READ_PARAMS to ${PKG}_INIT_FIXED
56      (already the case for some pkgs, including recent MNC_init, e.g. thsice)
57    o call CALC_GW from DYNAMICS (instead of from FORWARD_STEP)
58    o Dissipation & phiHyd gradient are always added to gU,gV in timestep.F
59      (was already the case for dissipation with mom_vecinv,
60       and also the case for grad.PhiHyd when staggered-timeStep)
61      This will allow to put dissipation out-off the AB time-stepping.
62     Unfortunately, affects truncation error. Update output of exp. that "fails"
63      (cg2d matching number) and leave the others for later: front_relax(10),
64      global_ocean_pressure(10),ideal_2D_oce(10),internal_wave(9),lab_sea(12),
65      matrix_example(7!),natl_box(12),plume_on_slope(11),vermix(12x3,11x2).
66    
67    checkpoint57o_post
68    o fix MNC/MDSIO flags in PTRACERS so that (1) it works, and
69      (2) its ready to be documented during the 20050801 DocFest
70    o MNC-ify the gmredi package -- tested and works w/ and w/o mnc
71      for ideal_2D_oce and lab_sea on linux_ia32_g77
72    o set to #undef CTRL_SET_OLD_MAXCVARS_30
73      in global1x1_tot/code_seaice_adj to access indices 32, 33
74      (worth another tag)
75    
76    checkpoint57n_post
77    o adding precip control xx_precip 32
78    o adding swflux control xx_swflux 33
79    o Replacing 10 forcing penalty cost routines by 1 generic.
80    o Implementing partitioning in time-mean and variable adjustment
81      for atmos. state.
82    o Time-mean constant error is now read in data.ecco (instead of hard-coded)
83    o in natl_box_adjoint:
84      * updated exp 1 to 10
85        (but does not have time-mean vs. variable split results yet)
86    o updated global1x1/*_seaice_adj/
87      to incorporate latest changes
88    o enable useSingleCpuIO for mdsio vector routines
89      (applies in particular to tapelev I/O)
90    o removed inefficient K-loop in all active_file*control*.F
91    
92    checkpoint57m_post
93    o re-arrange exp. adjustment.cs-32x32x1 (adjust_nlfs.cs-32x32x1 merge into)
94      and advect_cs (use EXCH-2 and standard cs-32 grid files).
95    o pkg/exch2: filling of face-corner halo regions is optional
96      (ifdef W2_FILL_NULL_REGIONS) and is turned off by default.
97    
98    checkpoint57l_post
99     tag before updating tutorials (pre-release-2)
100    o add cos & sin of grid-direction orientation angle (curvilinear grid only,
101       for output and interpolation of input fields onto model grid)
102    o fix radius in mom_v_metric_cylinder.F (wrong by dy/2).
103       Affects results of exp. rotating_tank ; update output.txt.
104    o pkg/diagnostics: 2 new S/R to fill a diagnostics using a scaling factor
105          and taking the square quantity and/or using a fraction-weight field.
106    o fix aim_diagnostics_init.F mate numbers.
107    o add mnc output capability to diagnostics/diagstat and update
108      our cvsignore files for the ACSII output generated
109    
110    checkpoint57k_post
111    o lab_sea now uses diagnostics package and provides a suite of
112      new EXF diagnostics output.
113    
114    checkpoint57j_post
115    o exf
116      * bug fix in exf_bulkformulae for psimh (spotted by Eliyahu Biton):
117        Bracket missing in eqn. for psimh (eqn. 7 of Large & Pond, 1982);
118        terms -2*ATAN(x) + pi/2 were added to both stable and unstable case.
119      * extended diagnostics output
120        - now includes all EXF variables
121        - hs, hl moved to common block
122        - separate S/R for diagnostics, called after ctrl vector is added
123        - name changed for EXFsw -> EXFswnet, EXFlw -> EXFlwnet
124        - EXFqnet contains true Qnet (i.e. includes qsw)
125      * updated verif. lab_sea, global_with_exf
126      * Rearranging hflux (exf_mapfields -> exf_getforcing)
127        to ensure that diagnostics sees a true EXFqnet
128    o add matlab scripts for CS-grid vectors (in utils/cs_grid)
129    o diagnostics pkg: change pointers so that 1 diagnostic can be used
130      several times with different frequencies.
131    o mnc-ify the thsice package as requested by Daniel Enderton
132      - the monitor--MNC output needs work
133      - many attributes need to be added (most are currently blank)
134    o mnc-ify theaim_v23 package as requested by Daniel Enderton
135      - many attributes need to be added (most are currently blank)
136    o remove "groundAtK1" & "rkFac" (replaced by usingPCoords & -rkSign)
137    o add Sadourny like discretization to the 4th.O vorticity advection scheme
138    o fix bug in rStar code (calc_r_star.F) when used with topo/bathy.
139      update output.txt from: aim.5l_cs (& .thSI), cpl_aim+ocn,
140         fizhi-gridalt-hs and global_ocean.cs32x15 (& .thsice).
141    o fix few little things to avoid floating error with -ftrapuv (ifort v9)
142     (ini_spherical_polar_grid.F, calc_r_star.F, monitor/mon_surfcor.F)
143    
144    checkpoint57i_post
145    o Diagnostics package was changed: diagnostic allocation is now deactivated
146      by setting an empty file name in the namelist (used to be by setting 0 frequency)
147    o momentum advection (VI form) options: activate 4th.O vorticity Coriolis ;
148      add 1rst Order upwind vertical Shear.
149    o add a quick fix for A/B checkpointing in OFFLINE mode
150    o add IGNORE_TIME define and -ignore_time option to genmake2 as an
151      end-run around the C/Fortran linking horror in eesup/src/timers.F
152    o added pkg/runclock: allows user to terminate run based on wall clock
153    o added non-hydrostatic scaling parameter: nh_am2
154    o pkg/my82: futile attempt to make results compiler-independent by adding
155      some "_d 0", etc. no effect.
156    o for mnc output, fill the 'T' coordinate var with myTime and create a
157      separate 'iter' variable for iteration count
158    o pkg/diagnostics:
159      add new capability: output of Global/Regional & per-level statistics ;
160      tested against monitor output (including land & thSIce) on various exp.
161    o make seaice-pkg I/O type flags (MNC/MDS) more standard.
162    
163    checkpoint57h_done
164      tag after changing user customized files (DIAGNOSTICS_SIZE.h,
165      data.diagnostics, data.gchem, data.ptracers) is done.
166    
167    o pkg/diagnostics: prepare for Global/Regional statistics.
168      add 2nd namelist in data.diagnostics and update DIAGNOSTICS_SIZE.h
169    o remove "baseTime" (no used) from arg. list of DIFF_BASE_MULTIPLE
170      and rename it: DIFFERENT_MULTIPLE
171    
172    checkpoint57h_post
173    o move tIter0 from data.gchem to PTRACERS_Iter0 in data.ptracers
174    o pkg/diagnostics: change output frequency, now in seconds (instead
175      of Nb of iterations). This requires to change data.diagnostics.
176    checkpoint57h_pre
177    
178    o in mnc, let the user create the output dir if both mnc_outdir_date
179      and mnc_outdir_num are false
180    o add fflags() to pkg/diagnostics which allows one to specify, on a
181      per-file basis, the file precision [default behavior is unchanged]
182    o added diagnostics to pkg/kpp, including computation of mixed layer
183      depth based on a temperature/density criterion
184    o updated verification/natl_box to test the new pkg/kpp diagnostics
185    o bugs fixed (with useAbsVorticity=T & with useJamartMomAdv=T)
186    o test AB-3 code with 4th.Order advection scheme (advect_xy/input.ab3_c4)
187    o fix mnc flags in pkg/seaice so that they are "owned" by seaice,
188      not mnc -- this mistake was found by JMC and is now corrected
189    
190    checkpoint57g_post
191    o add Adams-Bashforth 3rd Order time stepping:
192      - default remains AB-2 (#undef ALLOW_ADAMSBASHFORTH_3)
193      - not yet implemented with NH, CD_Scheme, pTracers, MNC_pickup ...
194    checkpoint57g_pre
195    
196    o make lambda[Theta,Salt]ClimRelax spatially varying
197      (default remains spatially uniform constant based on tau)
198    o added new control variables
199      * init. uVel, vVel, etanN
200      * lambda[Theta,Salt]ClimRelax
201    o separate masks used for ctrl_pack/unpack 'from write_grid' output
202      (suggested by G. Forget)
203    
204    checkpoint57f_post
