5      ==============================      ==============================
6    
7  o adding precip control xx_precip  o vorticity & strain are now computed without masking, to account for
8  o moved ptracer ctrl index 17 -> 32    no-slip-side BC in variable viscosity calculation ; mask is applied
9      anyway later on, before computing advection/coriolis terms.
10    o modify exp4 to test new obcs support reading from external files
11      and for passive tracers
12    o fix behavior of ptracers_monitor when monitor output is written to a
13      netcdf-file; still not independent of monitor.F (writes in the same
14      file).
15    o change default value of tRef (put a uniform, meaningful value for ocean
16      & atmos) and initialize sRef (was missing, as Martin mentioned).
17    o Redefine viscC?Leith*.  Change the coefficients of Leith viscosity
18      to be proportional to enstrophy dissipation length.  Thus,
19       viscC?leith?_new=pi*(viscC?leith?_old)^(1/3)
20      This is now consistent with Smagorinsky and with the manual.
21    
22    checkpoint57u_post
23    o OBCS and PTRACERS: add open boundary support for passive tracers
24      - either use homogenous (pseudo) v.Neumann conditions or prescribe
25        OB-values from file; this is not different from the way theta and salinity
26        are treated
27      - however, Orlanski-radiation conditions are not supported, and the model
28        will stop if you use pTracers and Orlanski at the same time.
29      - beefed up the rountine obcs_external_fields_load: now only those open
30        boundary values are overwritten with values from files for which there
31        are really files, otherwise the OB-fields remain untouched. This makes
32        it possible to use different OBs at different ends of the domain (as
33        with EXF)
34    o reduce number of exch calls in shap_filt (s2).
35    o CS-grid: fix divergence contribution to Leith viscosity. Affects (@
36      truncation level) 4/5 MLAdjust test results (11&12 digits match).
37    
38    checkpoint57t_post
39    o test biharmonic viscosity + no-slip with exp: global_ocean.cs32x15.viscA4
40    o finish adding brackets (coriolis S/R, vecinv) in multi-terms sum to get
41      same truncation, independent of the face number: affects affects several
42      test. exp.: Update global_ocean.cs32x15 (+.thsice) & MLAdjust (all 5).
43    o fix bug in mom_v_sidedrag (biharmonic viscosity was counted 2 times);
44      note that biharmonic viscosity + no-slip was not tested in any experiment.
45    o fix bug in non-linear free-surf side-drag ; generate new output for
46      global_ocean.cs32x15(+.thsice) & global_ocean_pressure.
47    o make mnc honor the writeBinaryPrec flag for most kinds of output
48    o eesupp: split EEPARAMS into EESIZE/EEPARAMS and add a vector global sum
49    o minor change in averaging W (mom_vi_?_vertshear.F) that affects truncation
50      error; update output from global_ocean.cs32x15(+.thsice) & MLAdjust (all 5).
51    o add brackets in multi-terms sum to get same truncation, independent of
52      the face number (manage to get exactly same value of gU,gV at the cs-edge)
53      affects several test. exp. Update global_ocean.cs32x15 (+.thsice).
54    o Clean, new version of mom_calc_visc.  Adds a new feature, viscAhRemax
55      and viscA4Remax, which allow one to limit the minimum viscosity by specifying
56      a maximum grid-scale Reynolds number.  Also, changes all length calculations
57      in the case of grid anisotropy to geometric mean of dx**2 and dy**2.
58      Suggested values of viscosity parameters found in mom_calc_visc.
59      Many new viscosity diagnostics available.
60    
61    checkpoint57s_post
62    o Add clearing-house for viscosity calculations, mom_calc_visc and
63      correct numerous bugs in LeithD and Smagorinsky discretizations.  
64      mom_calc_visc now allows for Smagorinsky, Leith and LeithD to be
65      used simultaneously, and to be used in mom_vecinv and mom_fluxform.
66      Mom_vecinv can be used with standard viscous calculation (mom_vi_hdissip.F)
67      and with Strain-Tension viscous term calculation (mom_hdissip.F).  
68      The Strain-Tension form is now called with useStrainTensonVisc=.true.
69      ViscAhStrain and viscAhTension are now retired.
70    o diagnostics "VISCAHD" & "VISCA4D" replace "VISCAH" & "VISCA4".
71    o In response to JMC's bug report, genmake2 now ignores any soft-links
72      that it finds in the *current* directory when searching for files.
73      Soft-links found in any other source directories will still work as
74      they did before.
75    o add HAVE_SETRLSTK define and useSETRLSTK flag (eedata) which calls
76      a C routine to unlimit the stack size
77    o mnc-ify pkg/aim snapshot vars
78    o mnc-ify pkg/land as requested by Daniel
79    o various changes to mnc including:
80      - all files use the new "BASENAME[[.ITER].{t|f}NUM].nc" format
81      - output can now be grouped so that all files within a group
82          change the ITER portion of their names in lock-step together
83      - can now read ("global") PER-FACE (in addition to PER-TILE) files
84          and works with both EXCH1 and EXCH2 (but needs more testing)
85      - writing works for all verification test cases w/ g77 on Linux
86    
87    checkpoint57r_post
88    o make MNC variable initialization happen earlier
89    o add diagnostics for (almost) each term of the momentum Eq.
90    o remove SST,SSS,UVEL_k2,VVEL_k2 diagnostics.
91    o move pkg timeave out of pkg-groups "oceanic" & "atmospheric" (pkg/pkg_groups)
92    o remove MINIMAL_TAVE_OUTPUT option ;
93      add "dumpInitAndLast" to replace "nodumps" (and MINIMAL_TAVE_OUTPUT).
94    o move some basic S/R (used elsewhere in the code) from pkg/mdsio to eesupp/src
95      allows to compile without pkg/mdsio (& test successfully hs94.1x64x5)
96    o add MNC output for adjoint of EXF (adexf), SEAICE (adseaice)
97    o add time-dependent SST, SSS control
98    o cost terms in ecco/ modularized (new cost_generic.F)
99    o cost_averages routines are modularized (new cost_averagesgeneric.F)
100    o new infrastructure for seaice model vs. obs misfits in seaice/
101      * driver from the_main_loop.F is seaice_cost_driver.F
102      * first term is AREA vs. SMR observation misfit (ALLOW_SEAICE_COST_SMR_AREA)
103      * gradient check in Exp. 6a of natl_box_adjoint/
104    o natl_box_adjoint input_seaice for Lab. Sea now available online via wget
105      (see README file)
106    
107    checkpoint57q_post
108    o fix initialisation Pb in calc_gw (get NANs in exp5 with g77)
109    o fix annoying months-old bug in mnc/mdsio output for seaice pkg
110      - bug was reported by Jean-Michel and Ian Fenty
111    o fix initialization Pb in AIM-Ocean coupled model (aim_sice2aim.F)
112      update exp. cpl_aim+ocn output.
113    o Implement 4-level checkpointing: AUTODIFF_4_LEVEL_CHECKPOINT
114      Needed for high-res. runs with large global files
115      to be able to limit tapelev size
116    o Changed some tests for adjoint:
117      * carbon/ now tests AUTODIFF_2_LEVEL_CHECKPOINT
118      * natl_box_adjoint/code_bulk/ tests AUTODIFF_4_LEVEL_CHECKPOINT
119      * global_ocean.90x40x15/ back to default 3-level checkpointing
120    o Modifications to enable scripted COMMON to MODULE conversion
121      * verification/OpenAD/code/ has necessary scripts and description;
122      * converts, compiles and runs successfully;
123    
124    checkpoint57p_post
125    o reading of delXfile & delYfile moved from ini_parms.F to ini_grid.F
126    o move ${PKG}_MNC_INIT from ${PKG}_READ_PARAMS to ${PKG}_INIT_FIXED
127      (already the case for some pkgs, including recent MNC_init, e.g. thsice)
128    o call CALC_GW from DYNAMICS (instead of from FORWARD_STEP)
129    o Dissipation & phiHyd gradient are always added to gU,gV in timestep.F
130      (was already the case for dissipation with mom_vecinv,
131       and also the case for grad.PhiHyd when staggered-timeStep)
132      This will allow to put dissipation out-off the AB time-stepping.
133     Unfortunately, affects truncation error. Update output of exp. that "fails"
134      (cg2d matching number) and leave the others for later: front_relax(10),
135      global_ocean_pressure(10),ideal_2D_oce(10),internal_wave(9),lab_sea(12),
136      matrix_example(7!),natl_box(12),plume_on_slope(11),vermix(12x3,11x2).
137    
138    checkpoint57o_post
139    o fix MNC/MDSIO flags in PTRACERS so that (1) it works, and
140      (2) its ready to be documented during the 20050801 DocFest
141    o MNC-ify the gmredi package -- tested and works w/ and w/o mnc
142      for ideal_2D_oce and lab_sea on linux_ia32_g77
143    o set to #undef CTRL_SET_OLD_MAXCVARS_30
144      in global1x1_tot/code_seaice_adj to access indices 32, 33
145      (worth another tag)
146    
147    checkpoint57n_post
148    o adding precip control xx_precip 32
149    o adding swflux control xx_swflux 33
150    o Replacing 10 forcing penalty cost routines by 1 generic.
151    o Implementing partitioning in time-mean and variable adjustment
152      for atmos. state.
153    o Time-mean constant error is now read in data.ecco (instead of hard-coded)
154  o in natl_box_adjoint:  o in natl_box_adjoint:
155    * updated: results_bulk/    * updated exp 1 to 10
156    * not yet updated: results/, results_seaice/      (but does not have time-mean vs. variable split results yet)
157    o updated global1x1/*_seaice_adj/
158      to incorporate latest changes
159    o enable useSingleCpuIO for mdsio vector routines
160      (applies in particular to tapelev I/O)
161    o removed inefficient K-loop in all active_file*control*.F
162    
163  checkpoint57m_post  checkpoint57m_post
164  o re-arrange exp. adjustment.cs-32x32x1 (adjust_nlfs.cs-32x32x1 merge into)  o re-arrange exp. adjustment.cs-32x32x1 (adjust_nlfs.cs-32x32x1 merge into)
