7    I'LL TAG TOMORROW
8    
9    o adding precip control xx_precip 32
10    o adding swflux control xx_swflux 33
11    o Replacing 10 forcing penalty cost routines by 1 generic.
12    o Implementing partitioning in time-mean and variable adjustment
13      for atmos. state.
14    o Time-mean constant error is now read in data.ecco (instead of hard-coded)
15    o in natl_box_adjoint:
16      * updated exp 1 to 10
17        (but does not have time-mean vs. variable split results yet)
18    o enable useSingleCpuIO for mdsio vector routines
19      (applies in particular to tapelev I/O)
20    o removed inefficient K-loop in all active_file*control*.F
21    
22    checkpoint57m_post
23    o re-arrange exp. adjustment.cs-32x32x1 (adjust_nlfs.cs-32x32x1 merge into)
24      and advect_cs (use EXCH-2 and standard cs-32 grid files).
25    o pkg/exch2: filling of face-corner halo regions is optional
26      (ifdef W2_FILL_NULL_REGIONS) and is turned off by default.
27    
28    checkpoint57l_post
29     tag before updating tutorials (pre-release-2)
30    o add cos & sin of grid-direction orientation angle (curvilinear grid only,
31       for output and interpolation of input fields onto model grid)
32    o fix radius in mom_v_metric_cylinder.F (wrong by dy/2).
33       Affects results of exp. rotating_tank ; update output.txt.
34    o pkg/diagnostics: 2 new S/R to fill a diagnostics using a scaling factor
35          and taking the square quantity and/or using a fraction-weight field.
36    o fix aim_diagnostics_init.F mate numbers.
37    o add mnc output capability to diagnostics/diagstat and update
38      our cvsignore files for the ACSII output generated
39    
40    checkpoint57k_post
41    o lab_sea now uses diagnostics package and provides a suite of
42      new EXF diagnostics output.
43    
44    checkpoint57j_post
45    o exf
46      * bug fix in exf_bulkformulae for psimh (spotted by Eliyahu Biton):
47        Bracket missing in eqn. for psimh (eqn. 7 of Large & Pond, 1982);
48        terms -2*ATAN(x) + pi/2 were added to both stable and unstable case.
49      * extended diagnostics output
50        - now includes all EXF variables
51        - hs, hl moved to common block
52        - separate S/R for diagnostics, called after ctrl vector is added
53        - name changed for EXFsw -> EXFswnet, EXFlw -> EXFlwnet
54        - EXFqnet contains true Qnet (i.e. includes qsw)
55      * updated verif. lab_sea, global_with_exf
56      * Rearranging hflux (exf_mapfields -> exf_getforcing)
57        to ensure that diagnostics sees a true EXFqnet
58    o add matlab scripts for CS-grid vectors (in utils/cs_grid)
59    o diagnostics pkg: change pointers so that 1 diagnostic can be used
60      several times with different frequencies.
61    o mnc-ify the thsice package as requested by Daniel Enderton
62      - the monitor--MNC output needs work
63      - many attributes need to be added (most are currently blank)
64    o mnc-ify theaim_v23 package as requested by Daniel Enderton
65      - many attributes need to be added (most are currently blank)
66    o remove "groundAtK1" & "rkFac" (replaced by usingPCoords & -rkSign)
67    o add Sadourny like discretization to the 4th.O vorticity advection scheme
68    o fix bug in rStar code (calc_r_star.F) when used with topo/bathy.
69      update output.txt from: aim.5l_cs (& .thSI), cpl_aim+ocn,
70         fizhi-gridalt-hs and global_ocean.cs32x15 (& .thsice).
71    o fix few little things to avoid floating error with -ftrapuv (ifort v9)
72     (ini_spherical_polar_grid.F, calc_r_star.F, monitor/mon_surfcor.F)
73    
74    checkpoint57i_post
75    o Diagnostics package was changed: diagnostic allocation is now deactivated
76      by setting an empty file name in the namelist (used to be by setting 0 frequency)
77    o momentum advection (VI form) options: activate 4th.O vorticity Coriolis ;
78      add 1rst Order upwind vertical Shear.
79    o add a quick fix for A/B checkpointing in OFFLINE mode
80    o add IGNORE_TIME define and -ignore_time option to genmake2 as an
81      end-run around the C/Fortran linking horror in eesup/src/timers.F
82    o added pkg/runclock: allows user to terminate run based on wall clock
83    o added non-hydrostatic scaling parameter: nh_am2
84    o pkg/my82: futile attempt to make results compiler-independent by adding
85      some "_d 0", etc. no effect.
86    o for mnc output, fill the 'T' coordinate var with myTime and create a
87      separate 'iter' variable for iteration count
88    o pkg/diagnostics:
89      add new capability: output of Global/Regional & per-level statistics ;
90      tested against monitor output (including land & thSIce) on various exp.
91    o make seaice-pkg I/O type flags (MNC/MDS) more standard.
92    
93    checkpoint57h_done
94      tag after changing user customized files (DIAGNOSTICS_SIZE.h,
95      data.diagnostics, data.gchem, data.ptracers) is done.
96    
97    o pkg/diagnostics: prepare for Global/Regional statistics.
98      add 2nd namelist in data.diagnostics and update DIAGNOSTICS_SIZE.h

100      and rename it: DIFFERENT_MULTIPLE
101    
102    checkpoint57h_post
103    o move tIter0 from data.gchem to PTRACERS_Iter0 in data.ptracers
104    o pkg/diagnostics: change output frequency, now in seconds (instead
105      of Nb of iterations). This requires to change data.diagnostics.
106    checkpoint57h_pre
107    
108    o in mnc, let the user create the output dir if both mnc_outdir_date
109      and mnc_outdir_num are false
110    o add fflags() to pkg/diagnostics which allows one to specify, on a
111      per-file basis, the file precision [default behavior is unchanged]
112    o added diagnostics to pkg/kpp, including computation of mixed layer
113      depth based on a temperature/density criterion
114    o updated verification/natl_box to test the new pkg/kpp diagnostics
115    o bugs fixed (with useAbsVorticity=T & with useJamartMomAdv=T)
116    o test AB-3 code with 4th.Order advection scheme (advect_xy/input.ab3_c4)
117    o fix mnc flags in pkg/seaice so that they are "owned" by seaice,
118      not mnc -- this mistake was found by JMC and is now corrected
119    
120    checkpoint57g_post
121    o add Adams-Bashforth 3rd Order time stepping:
122      - default remains AB-2 (#undef ALLOW_ADAMSBASHFORTH_3)
123      - not yet implemented with NH, CD_Scheme, pTracers, MNC_pickup ...
124    checkpoint57g_pre
125    
126    o make lambda[Theta,Salt]ClimRelax spatially varying
127      (default remains spatially uniform constant based on tau)

129      * init. uVel, vVel, etanN
130      * lambda[Theta,Salt]ClimRelax
131    o separate masks used for ctrl_pack/unpack 'from write_grid' output
132      (suggested by G. Forget)
133    
134    checkpoint57f_post
135    o add parameter "baseTime" = model base time = time at iteration zero
136      new function DIFF_BASE_MULTIPLE (replace DIFFERENT_MULTIPLE) to
137      account for baseTime shift

144    o S/R ptracers_calc_diff: argument list bug for CALL KPP_CALC_DIFF_S
145    o added modified Leith scheme with viscosity proportional to grad(Hdiv)
146      as well as grad(vort3).  Made it compatible with both approximate form
147      for the cubed sphere and full form of these gradients.  Added flag
148      useFullLeith to select between approximate and full form.  
149    o add "d0" in getcon.F to reduce differences between compilers/platforms
150      update output.txt of exp. fizhi-gridalt-hs
151    o change port_rand funtion to allow to set the seed.
152    o fix obscure MNC bug involving conversion between reals and integers
153      - it caused no problems with certain (eg. gcc, ifc) compilers but the
154        new version is now more standards-compliant
155    o adjoint-related modifications
156      * gad_dst3_adv_?: to be able to use advscheme=30 in adjoint

169      (360-372 days) for parameters chkPtFreq, pChkPtFreq, taveFreq, SEAICE_taveFreq,
170      KPP_taveFreq, and freq in pkg/diagnostics are converted to exact calendar
171      months and years.  Requires pkg/cal.
172    o diagnostics: add pickup functionality

179    o pkg/thsice used in the ocean: fix tile Pb related to sIceLoad forcing
180    o modify verification/ideal_2D_oce so that it tests the creation of mnc
181      output from the diagnostics package
182    o temporary fix in EXCH2_UV: add a 3rd call to fix the 24.tiles CS-grid set-up
183    o make genmake2 more portable by using ".$FS" instead of ".f" for more
184      of the test compilations (eg. IBM xlf on Mac OSX w/HFS filesys)
185    o add coordinate variables to the MNC output from the diagnostics package
186    o change MNC-flags default value: true when useMNC=TRUE
187    o add a "readgrid_mnc" flag to MNC and give model/src/ini_curvilinear_grid.F

190    o diagnostics: fix a bug (sub-set of levels); keep full precision when averaging
191    o do snap-shot diagnostics at the middle of the time-interval (instead of
192      at the end).
193    o update exp. aim.5l_cs (use default LAND_OPTIONS.h file) and add
194      new test for AIM with thSIce + slab-ocean
195    o cpl_aim+ocn test: update output (optfile & default GMREDI_OPTIONS.h)
196    o move state variable diagnostics to the beginning of the time step ;
197      (note: still needs some work specially for snap-shot diagnostics)
198      duplicate & replace UVELVVEL diagnostics with UV_VEL_C & UV_VEL_Z

209    o add saltFlux(+File) forcing capability with periodicExternalForcing
210    o allow to use pkg diagnostics for GM-Redi & ThSIce output
211    o diagnostics_fill: fill in up to sNx+1 or sNy+1 (if U,V or Z pt) for mnc.
212    o improvements for the MNC output from DIAGNOSTICS:
213      - correct handling of the unlimitied dimension
214      - all dims now have associated coordinate variables
215      - variables located at U, V, and Corner ("Z") points are now written
216        with the correct horzontal dimensions (eg. 'Xp1', 'Yp1') so that
