5      ==============================      ==============================
6    
7    o add cos & sin of grid-direction orientation angle (curvilinear grid only,
8       for output and interpolation of input fields onto model grid)
9    o fix radius in mom_v_metric_cylinder.F (wrong by dy/2).
10       Affects results of exp. rotating_tank ; update output.txt.
11    o pkg/diagnostics: 2 new S/R to fill a diagnostics using a scaling factor
12          and taking the square quantity and/or using a fraction-weight field.
13    o fix aim_diagnostics_init.F mate numbers.
14    o add mnc output capability to diagnostics/diagstat and update
15      our cvsignore files for the ACSII output generated
16    
17    checkpoint57k_post
18    o lab_sea now uses diagnostics package and provides a suite of
19      new EXF diagnostics output.
20    
21    checkpoint57j_post
22    o exf
23      * bug fix in exf_bulkformulae for psimh (spotted by Eliyahu Biton):
24        Bracket missing in eqn. for psimh (eqn. 7 of Large & Pond, 1982);
25        terms -2*ATAN(x) + pi/2 were added to both stable and unstable case.
26      * extended diagnostics output
27        - now includes all EXF variables
28        - hs, hl moved to common block
29        - separate S/R for diagnostics, called after ctrl vector is added
30        - name changed for EXFsw -> EXFswnet, EXFlw -> EXFlwnet
31        - EXFqnet contains true Qnet (i.e. includes qsw)
32      * updated verif. lab_sea, global_with_exf
33      * Rearranging hflux (exf_mapfields -> exf_getforcing)
34        to ensure that diagnostics sees a true EXFqnet
35    o add matlab scripts for CS-grid vectors (in utils/cs_grid)
36    o diagnostics pkg: change pointers so that 1 diagnostic can be used
37      several times with different frequencies.
38    o mnc-ify the thsice package as requested by Daniel Enderton
39      - the monitor--MNC output needs work
40      - many attributes need to be added (most are currently blank)
41    o mnc-ify theaim_v23 package as requested by Daniel Enderton
42      - many attributes need to be added (most are currently blank)
43    o remove "groundAtK1" & "rkFac" (replaced by usingPCoords & -rkSign)
44    o add Sadourny like discretization to the 4th.O vorticity advection scheme
45    o fix bug in rStar code (calc_r_star.F) when used with topo/bathy.
46      update output.txt from: aim.5l_cs (& .thSI), cpl_aim+ocn,
47         fizhi-gridalt-hs and global_ocean.cs32x15 (& .thsice).
48    o fix few little things to avoid floating error with -ftrapuv (ifort v9)
49     (ini_spherical_polar_grid.F, calc_r_star.F, monitor/mon_surfcor.F)
50    
51    checkpoint57i_post
52    o Diagnostics package was changed: diagnostic allocation is now deactivated
53      by setting an empty file name in the namelist (used to be by setting 0 frequency)
54    o momentum advection (VI form) options: activate 4th.O vorticity Coriolis ;
55      add 1rst Order upwind vertical Shear.
56    o add a quick fix for A/B checkpointing in OFFLINE mode
57    o add IGNORE_TIME define and -ignore_time option to genmake2 as an
58      end-run around the C/Fortran linking horror in eesup/src/timers.F
59    o added pkg/runclock: allows user to terminate run based on wall clock
60    o added non-hydrostatic scaling parameter: nh_am2
61    o pkg/my82: futile attempt to make results compiler-independent by adding
62      some "_d 0", etc. no effect.
63    o for mnc output, fill the 'T' coordinate var with myTime and create a
64      separate 'iter' variable for iteration count
65    o pkg/diagnostics:
66      add new capability: output of Global/Regional & per-level statistics ;
67      tested against monitor output (including land & thSIce) on various exp.
68    o make seaice-pkg I/O type flags (MNC/MDS) more standard.
69    
70    checkpoint57h_done
71      tag after changing user customized files (DIAGNOSTICS_SIZE.h,
72      data.diagnostics, data.gchem, data.ptracers) is done.
73    
74    o pkg/diagnostics: prepare for Global/Regional statistics.
75      add 2nd namelist in data.diagnostics and update DIAGNOSTICS_SIZE.h
76    o remove "baseTime" (no used) from arg. list of DIFF_BASE_MULTIPLE
77      and rename it: DIFFERENT_MULTIPLE
78    
79    checkpoint57h_post
80    o move tIter0 from data.gchem to PTRACERS_Iter0 in data.ptracers
81    o pkg/diagnostics: change output frequency, now in seconds (instead
82      of Nb of iterations). This requires to change data.diagnostics.
83    checkpoint57h_pre
84    
85    o in mnc, let the user create the output dir if both mnc_outdir_date
86      and mnc_outdir_num are false
87    o add fflags() to pkg/diagnostics which allows one to specify, on a
88      per-file basis, the file precision [default behavior is unchanged]
89    o added diagnostics to pkg/kpp, including computation of mixed layer
90      depth based on a temperature/density criterion
91    o updated verification/natl_box to test the new pkg/kpp diagnostics
92    o bugs fixed (with useAbsVorticity=T & with useJamartMomAdv=T)
93    o test AB-3 code with 4th.Order advection scheme (advect_xy/input.ab3_c4)
94    o fix mnc flags in pkg/seaice so that they are "owned" by seaice,
95      not mnc -- this mistake was found by JMC and is now corrected
96    
97    checkpoint57g_post
98    o add Adams-Bashforth 3rd Order time stepping:
99      - default remains AB-2 (#undef ALLOW_ADAMSBASHFORTH_3)
100      - not yet implemented with NH, CD_Scheme, pTracers, MNC_pickup ...
101    checkpoint57g_pre
102    
103    o make lambda[Theta,Salt]ClimRelax spatially varying
104      (default remains spatially uniform constant based on tau)
105    o added new control variables
106      * init. uVel, vVel, etanN
107      * lambda[Theta,Salt]ClimRelax
108    o separate masks used for ctrl_pack/unpack 'from write_grid' output
109      (suggested by G. Forget)
110    
111    checkpoint57f_post
112    o add parameter "baseTime" = model base time = time at iteration zero
113      new function DIFF_BASE_MULTIPLE (replace DIFFERENT_MULTIPLE) to
114      account for baseTime shift
115    o move Coriolis arrays from PARAMS.h to GRID.h
116    checkpoint57f_pre
117    
118    o mnc-ifying the seaice package
119    o introduced an alternative length scale calculation for use in the limiting
120      maximum viscosity (off by default, see mom_vi_hdissip.F for details)
121    o S/R ptracers_calc_diff: argument list bug for CALL KPP_CALC_DIFF_S
122    o added modified Leith scheme with viscosity proportional to grad(Hdiv)
123      as well as grad(vort3).  Made it compatible with both approximate form
124      for the cubed sphere and full form of these gradients.  Added flag
125      useFullLeith to select between approximate and full form.  
126    o add "d0" in getcon.F to reduce differences between compilers/platforms
127      update output.txt of exp. fizhi-gridalt-hs
128    o change port_rand funtion to allow to set the seed.
129    o fix obscure MNC bug involving conversion between reals and integers
130      - it caused no problems with certain (eg. gcc, ifc) compilers but the
131        new version is now more standards-compliant
132    o adjoint-related modifications
133      * gad_dst3_adv_?: to be able to use advscheme=30 in adjoint
134      * gad_calc_rhs: fool adjoint, revert to advscheme=30 in reverse when using 33
135      * mom_vi_hdissip: to be able to use Leith scheme in adjoint
136    
137    checkpoint57e_post
138    o Adding eddy stress controls a la Ferreira et al.

140    
141    o fizhi pkg: fix AtoC and CtoA when called with same input & output array
142      update output.txt of exp. fizhi-gridalt-hs
143    o add more "Z" dimensions and associated coordinate vars to MNC
144    o pkg/exf: added twoDigitYear capability for option useExfYearlyFields
145    o parameter calendarDumps: when set, approximate months (30-31 days) and years
146      (360-372 days) for parameters chkPtFreq, pChkPtFreq, taveFreq, SEAICE_taveFreq,
147      KPP_taveFreq, and freq in pkg/diagnostics are converted to exact calendar
148      months and years.  Requires pkg/cal.
149    o diagnostics: add pickup functionality
150      - off by default for backwards compatibility
151      - current version only uses MDSIO -- MNC will be added
152    o allow to use pkg diagnostics for LAND pkg output & Shapiro Tendencies.
153    o pkg/shap_filt: fix for multi-tiles per face (CS-grid with EXCH2)
154    
155    checkpoint57d_post
156    o pkg/thsice used in the ocean: fix tile Pb related to sIceLoad forcing
157    o modify verification/ideal_2D_oce so that it tests the creation of mnc
158      output from the diagnostics package
159    o temporary fix in EXCH2_UV: add a 3rd call to fix the 24.tiles CS-grid set-up
160    o make genmake2 more portable by using ".$FS" instead of ".f" for more
161      of the test compilations (eg. IBM xlf on Mac OSX w/HFS filesys)
162    o add coordinate variables to the MNC output from the diagnostics package
163    o change MNC-flags default value: true when useMNC=TRUE
164  o add a "readgrid_mnc" flag to MNC and give model/src/ini_curvilinear_grid.F  o add a "readgrid_mnc" flag to MNC and give model/src/ini_curvilinear_grid.F
