5      ==============================      ==============================
6    
7    o clean up 3-dim. relaxation codes:
8      * Fix I/O inconsistency in pkg/rbcs: replace precFloat32 by readBinaryPrec
9      * Remove 3-dim. relaxation code from pkg/exf (now use only pkg/rbcs)
10      * Thanks to Tom Haine for testing!
11    
12    checkpoint57z_post
13    o make CG3D solver compatible with Free-surface at k > 1 (p-coordinate):
14      affects output (@ truncation level) of exp. plume_on_slope ; updated.
15    o fix the pickup behavior for obcs in combination with ptracers
16    o fix a bug in ptracers_external_fields_load
17    o no AB-2 at the first iteration for Gw (consistent with Gu,Gv,Gt,Gs ...)
18      affects results of NH experiments (but all our NH tests have Gw[it=1]==0 !!)
19    o transfered surface NH pressure to eta field (if exactConserv).
20    o gmredi: fix bugs in slope tapering ldd97 (depthZ had the wrong sign)
21         and update lab_sea output.txt file.
22    o completing 3-dim. relaxation code: additional term
23         1/tau*( theta(i,j,k) - thetaStar(i,j,k) )
24      in S/R EXTERNAL_FORCING_T (file external_forcing.F)
25      * At compile time, in "EXF_OPTIONS.h" set
26          #define  ALLOW_CLIMTEMP_RELAXATION
27          #define  ALLOW_CLIMSALT_RELAXATION
28      * At runtime in "data", under &PARM03 set (e.g., units in seconds)
29          tauThetaClimRelax3Dim = 15552000.0,
30          tauSaltClimRelax3Dim  = 15552000.0,
31      * 3 cases:
32          1) Use a constant-in-time 3-dim. field
33          2) Provide 12 3-dim. fields corresponding to Jan., ... , Dec.
34          3) Real-time relax. to time-evolving prescribed field
35    o Adding Laplacian-type smoothness constraint on
36      initial and boundary (forcing) controls (ic, bc)
37      * enable at compile-time via
38        ALLOW_SMOOTH_IC_COST_CONTRIBUTION, ALLOW_SMOOTH_BC_COST_CONTRIBUTION
39      * enable at run-time via mult_smooth_ic = 1, mult_smooth_bc = 1
40      * Absolute scale somewhat unclear so far
41      * no area weighting was included since no other cost term does so far
42    
43    checkpoint57y_post
44    First step for a NLFS adjoint
45    o initially suppress rStar (new flag DISABLE_RSTAR_CODE)
46    o new init. routines for calc_r_star, calc_surf_dr
47    o still need to deal with ini_masks_etc
48    o testreport seemed happy
49    checkpoint57y_pre
50    
51    o obcs: always reset wVel & eta (to zero or prescribe it) at the OBs.
52    o add new package rbcs (for relaxing ptracers at boundaries/depth/surface etc)
53    o add new offset feature to offline pkg (plus minor cleanup)
54    o cfc fixes for final year of integration
55    o clean up GCHEM_OPTIONS.h/DIC_OPTIONS.h (all options should
56      be in GCHEM_OPTIONS).
57    
58    checkpoint57x_post
59    o fix testreport Pb in multiple test experiment.
60    o cleanup our namelist syntax in verification:
61      - make it more F95 standards compliant (some work still needed)
62      - allows the vast majority of our tests to work with gfortran
63    o Non-Hydrostatic:
64     - put all NH variables (formerly in DYNVARS.h & GW.h) in NH_VARS.h
65     - fix exchange calls for CS-grid using the new EXCH_S3D_RL.
66    o Allow to apply AB on T,S rather than on AB(gT,gS):
67     - implemented within #ifdef ALLOW_ADAMSBASHFORTH_3
68     - use the same arrays (gtNm,gsNm) to hold tracer field at previous
69       time-steps (if AB(T,S)) and tendencies (if AB(gT,gS)).
70     - need a "clever" read_pickup to restart from the other AB formulation
71    o move local commom bloc /GlobalLo/ (used for singleCpuIO) in EESUPPORT.h
72    o remove some unused variables (reduces number of compiler warnings)
73    o adjoint
74      * Disable useVariableViscosity for adjoint for time being
75        (there are a number of extensive recomputations)
76      * Initialize certain variables needed for adjoint
77    
78    checkpoint57w_post
79    o pkg/mdsio: use MAX_LEN_FNAM (instead of hard coded 80) for file-names
80                 fix the singleCpuIO RS version of MDSWRITEFIELD
81       and add a WARNING if using globalFiles=T with multi-processors.
82    o write grid-file(s) in only one format (MDS or MNC): default=MNC (if
83      using MNC); can force MDS output by setting writegrid_mnc=F in data.mnc
84    o tracer advection scheme:
85      add DST-2 (=Lax-Wendroff) & 1rst order upwind schemes (the way to get
86       those 2 schemes before, changing GAD_FLUX_LIMITER.h + to recompile,
87       was not very convenient).
88      add implicit version for DST-3 & DST3_Flux_Limit vertical advection;  
89       (further tests needed for the implicit DST & Flux-Limiter schemes).
90    o PTRACERS: added namelist parameter PTRACERS_ref in analogy to tRef
91      and sRef for convenience, handy, when you want to initialize
92      ptracers in a large domain with a constant non-zero value. Also,
93      untangle ptracers_init.F a little.
94    
95    checkpoint57v_post
96    o change dome exp. to use variable viscosity in side-drag terms.
97    o remove all the files from the cfc_offline test since they are now
98      incorporated into tutorial_cfc_offline which has been producing
99      identical results for a few days of testing
100    o add new parameter: sideDragFactor to enable half-slip-side BC
101      and change side-drag S/R to use viscosity from mom_calc_visc
102      (can switch back by setting sideDragFactor=0.); affects results at
103      truncation level; regenerate output for exp.: global_ocean.cs32x10(x3),
104       global_ocean_ebm, global_ocean_pressure, matrix_example & MLAdjust(x5).
105    o vorticity & strain are now computed without masking, to account for
106      no-slip-side BC in variable viscosity calculation ; mask is applied
107      anyway later on, before computing advection/coriolis terms.
108    o modify exp4 to test new obcs support for reading from external files
109      and for passive tracers
110    o fix behavior of ptracers_monitor when monitor output is written to a
111      netcdf-file; still not independent of monitor.F (writes in the same
112      file).
113    o change default value of tRef (put a uniform, meaningful value for ocean
114      & atmos) and initialize sRef (was missing, as Martin mentioned).
115    o Redefine viscC?Leith*.  Change the coefficients of Leith viscosity
116      to be proportional to enstrophy dissipation length.  Thus,
117       viscC?leith?_new=pi*(viscC?leith?_old)^(1/3)
118      This is now consistent with Smagorinsky and with the manual.
119    
120    checkpoint57u_post
121    o OBCS and PTRACERS: add open boundary support for passive tracers
122      - either use homogenous (pseudo) v.Neumann conditions or prescribe
123        OB-values from file; this is not different from the way theta and salinity
124        are treated
125      - however, Orlanski-radiation conditions are not supported, and the model
126        will stop if you use pTracers and Orlanski at the same time.
127      - beefed up the rountine obcs_external_fields_load: now only those open
128        boundary values are overwritten with values from files for which there
129        are really files, otherwise the OB-fields remain untouched. This makes
130        it possible to use different OBs at different ends of the domain (as
131        with EXF)
132    o reduce number of exch calls in shap_filt (s2).
133    o CS-grid: fix divergence contribution to Leith viscosity. Affects (@
134      truncation level) 4/5 MLAdjust test results (11&12 digits match).
135    
136    checkpoint57t_post
137    o test biharmonic viscosity + no-slip with exp: global_ocean.cs32x15.viscA4
138    o finish adding brackets (coriolis S/R, vecinv) in multi-terms sum to get
139      same truncation, independent of the face number: affects affects several
140      test. exp.: Update global_ocean.cs32x15 (+.thsice) & MLAdjust (all 5).
141    o fix bug in mom_v_sidedrag (biharmonic viscosity was counted 2 times);
142      note that biharmonic viscosity + no-slip was not tested in any experiment.
143  o fix bug in non-linear free-surf side-drag ; generate new output for  o fix bug in non-linear free-surf side-drag ; generate new output for
144    global_ocean.cs32x15(+.thsice) & global_ocean_pressure.    global_ocean.cs32x15(+.thsice) & global_ocean_pressure.
145  o make mnc honor the writeBinaryPrec flag for most kinds of output  o make mnc honor the writeBinaryPrec flag for most kinds of output
