4      Notes on tags used in MITgcmUV      Notes on tags used in MITgcmUV
5      ==============================      ==============================
6    
7    o make CG3D solver compatible with Free-surface at k > 1 (p-coordinate):
8      affects output (@ truncation level) of exp. plume_on_slope ; updated.
9    o fix the pickup behavior for obcs in combination with ptracers
10    o fix a bug in ptracers_external_fields_load
11    o no AB-2 at the first iteration for Gw (consistent with Gu,Gv,Gt,Gs ...)
12      affects results of NH experiments (but all our NH tests have Gw[it=1]==0 !!)
13    o transfered surface NH pressure to eta field (if exactConserv).
14    o gmredi: fix bugs in slope tapering ldd97 (depthZ had the wrong sign)
15         and update lab_sea output.txt file.
16    o completing 3-dim. relaxation code: additional term
17         1/tau*( theta(i,j,k) - thetaStar(i,j,k) )
18      in S/R EXTERNAL_FORCING_T (file external_forcing.F)
19      * At compile time, in "EXF_OPTIONS.h" set
20          #define  ALLOW_CLIMTEMP_RELAXATION
21          #define  ALLOW_CLIMSALT_RELAXATION
22      * At runtime in "data", under &PARM03 set (e.g., units in seconds)
23          tauThetaClimRelax3Dim = 15552000.0,
24          tauSaltClimRelax3Dim  = 15552000.0,
25      * 3 cases:
26          1) Use a constant-in-time 3-dim. field
27          2) Provide 12 3-dim. fields corresponding to Jan., ... , Dec.
28          3) Real-time relax. to time-evolving prescribed field
29    o Adding Laplacian-type smoothness constraint on
30      initial and boundary (forcing) controls (ic, bc)
31      * enable at compile-time via
32        ALLOW_SMOOTH_IC_COST_CONTRIBUTION, ALLOW_SMOOTH_BC_COST_CONTRIBUTION
33      * enable at run-time via mult_smooth_ic = 1, mult_smooth_bc = 1
34      * Absolute scale somewhat unclear so far
35      * no area weighting was included since no other cost term does so far
36    
37    checkpoint57y_post
38    First step for a NLFS adjoint
39    o initially suppress rStar (new flag DISABLE_RSTAR_CODE)
40    o new init. routines for calc_r_star, calc_surf_dr
41    o still need to deal with ini_masks_etc
42    o testreport seemed happy
43    checkpoint57y_pre
44    
45    o obcs: always reset wVel & eta (to zero or prescribe it) at the OBs.
46    o add new package rbcs (for relaxing ptracers at boundaries/depth/surface etc)
47    o add new offset feature to offline pkg (plus minor cleanup)
48    o cfc fixes for final year of integration
49    o clean up GCHEM_OPTIONS.h/DIC_OPTIONS.h (all options should
50      be in GCHEM_OPTIONS).
51    
52    checkpoint57x_post
53    o fix testreport Pb in multiple test experiment.
54    o cleanup our namelist syntax in verification:
55      - make it more F95 standards compliant (some work still needed)
56      - allows the vast majority of our tests to work with gfortran
57    o Non-Hydrostatic:
58     - put all NH variables (formerly in DYNVARS.h & GW.h) in NH_VARS.h
59     - fix exchange calls for CS-grid using the new EXCH_S3D_RL.
60    o Allow to apply AB on T,S rather than on AB(gT,gS):
61     - implemented within #ifdef ALLOW_ADAMSBASHFORTH_3
62     - use the same arrays (gtNm,gsNm) to hold tracer field at previous
63       time-steps (if AB(T,S)) and tendencies (if AB(gT,gS)).
64     - need a "clever" read_pickup to restart from the other AB formulation
65    o move local commom bloc /GlobalLo/ (used for singleCpuIO) in EESUPPORT.h
66    o remove some unused variables (reduces number of compiler warnings)
67    o adjoint
68      * Disable useVariableViscosity for adjoint for time being
69        (there are a number of extensive recomputations)
70      * Initialize certain variables needed for adjoint
71    
72    checkpoint57w_post
73    o pkg/mdsio: use MAX_LEN_FNAM (instead of hard coded 80) for file-names
74                 fix the singleCpuIO RS version of MDSWRITEFIELD
75       and add a WARNING if using globalFiles=T with multi-processors.
76    o write grid-file(s) in only one format (MDS or MNC): default=MNC (if
77      using MNC); can force MDS output by setting writegrid_mnc=F in data.mnc
78    o tracer advection scheme:
79      add DST-2 (=Lax-Wendroff) & 1rst order upwind schemes (the way to get
80       those 2 schemes before, changing GAD_FLUX_LIMITER.h + to recompile,
81       was not very convenient).
82      add implicit version for DST-3 & DST3_Flux_Limit vertical advection;  
83       (further tests needed for the implicit DST & Flux-Limiter schemes).
84    o PTRACERS: added namelist parameter PTRACERS_ref in analogy to tRef
85      and sRef for convenience, handy, when you want to initialize
86      ptracers in a large domain with a constant non-zero value. Also,
87      untangle ptracers_init.F a little.
88    
89    checkpoint57v_post
90    o change dome exp. to use variable viscosity in side-drag terms.
91    o remove all the files from the cfc_offline test since they are now
92      incorporated into tutorial_cfc_offline which has been producing
93      identical results for a few days of testing
94    o add new parameter: sideDragFactor to enable half-slip-side BC
95      and change side-drag S/R to use viscosity from mom_calc_visc
96      (can switch back by setting sideDragFactor=0.); affects results at
97      truncation level; regenerate output for exp.: global_ocean.cs32x10(x3),
98       global_ocean_ebm, global_ocean_pressure, matrix_example & MLAdjust(x5).
99    o vorticity & strain are now computed without masking, to account for
100      no-slip-side BC in variable viscosity calculation ; mask is applied
101      anyway later on, before computing advection/coriolis terms.
102    o modify exp4 to test new obcs support for reading from external files
103      and for passive tracers
104    o fix behavior of ptracers_monitor when monitor output is written to a
105      netcdf-file; still not independent of monitor.F (writes in the same
106      file).
107    o change default value of tRef (put a uniform, meaningful value for ocean
108      & atmos) and initialize sRef (was missing, as Martin mentioned).
109    o Redefine viscC?Leith*.  Change the coefficients of Leith viscosity
110      to be proportional to enstrophy dissipation length.  Thus,
111       viscC?leith?_new=pi*(viscC?leith?_old)^(1/3)
112      This is now consistent with Smagorinsky and with the manual.
113    
114    checkpoint57u_post
115    o OBCS and PTRACERS: add open boundary support for passive tracers
116      - either use homogenous (pseudo) v.Neumann conditions or prescribe
117        OB-values from file; this is not different from the way theta and salinity
118        are treated
119      - however, Orlanski-radiation conditions are not supported, and the model
120        will stop if you use pTracers and Orlanski at the same time.
121      - beefed up the rountine obcs_external_fields_load: now only those open
122        boundary values are overwritten with values from files for which there
123        are really files, otherwise the OB-fields remain untouched. This makes
124        it possible to use different OBs at different ends of the domain (as
125        with EXF)
126    o reduce number of exch calls in shap_filt (s2).
127    o CS-grid: fix divergence contribution to Leith viscosity. Affects (@
128      truncation level) 4/5 MLAdjust test results (11&12 digits match).
129    
130    checkpoint57t_post
131    o test biharmonic viscosity + no-slip with exp: global_ocean.cs32x15.viscA4
132    o finish adding brackets (coriolis S/R, vecinv) in multi-terms sum to get
133      same truncation, independent of the face number: affects affects several
134      test. exp.: Update global_ocean.cs32x15 (+.thsice) & MLAdjust (all 5).
135    o fix bug in mom_v_sidedrag (biharmonic viscosity was counted 2 times);
136      note that biharmonic viscosity + no-slip was not tested in any experiment.
137    o fix bug in non-linear free-surf side-drag ; generate new output for
138      global_ocean.cs32x15(+.thsice) & global_ocean_pressure.
139    o make mnc honor the writeBinaryPrec flag for most kinds of output
140    o eesupp: split EEPARAMS into EESIZE/EEPARAMS and add a vector global sum
141    o minor change in averaging W (mom_vi_?_vertshear.F) that affects truncation
142      error; update output from global_ocean.cs32x15(+.thsice) & MLAdjust (all 5).
143    o add brackets in multi-terms sum to get same truncation, independent of
144      the face number (manage to get exactly same value of gU,gV at the cs-edge)
145      affects several test. exp. Update global_ocean.cs32x15 (+.thsice).
146    o Clean, new version of mom_calc_visc.  Adds a new feature, viscAhRemax
147      and viscA4Remax, which allow one to limit the minimum viscosity by specifying
148      a maximum grid-scale Reynolds number.  Also, changes all length calculations
149      in the case of grid anisotropy to geometric mean of dx**2 and dy**2.
150      Suggested values of viscosity parameters found in mom_calc_visc.
151      Many new viscosity diagnostics available.
152    
153    checkpoint57s_post
154    o Add clearing-house for viscosity calculations, mom_calc_visc and
155      correct numerous bugs in LeithD and Smagorinsky discretizations.  
156      mom_calc_visc now allows for Smagorinsky, Leith and LeithD to be
157      used simultaneously, and to be used in mom_vecinv and mom_fluxform.
158      Mom_vecinv can be used with standard viscous calculation (mom_vi_hdissip.F)
159      and with Strain-Tension viscous term calculation (mom_hdissip.F).  
160      The Strain-Tension form is now called with useStrainTensonVisc=.true.
161      ViscAhStrain and viscAhTension are now retired.
162    o diagnostics "VISCAHD" & "VISCA4D" replace "VISCAH" & "VISCA4".
163    o In response to JMC's bug report, genmake2 now ignores any soft-links
164      that it finds in the *current* directory when searching for files.
165      Soft-links found in any other source directories will still work as
166      they did before.
167    o add HAVE_SETRLSTK define and useSETRLSTK flag (eedata) which calls
168      a C routine to unlimit the stack size
169    o mnc-ify pkg/aim snapshot vars
170    o mnc-ify pkg/land as requested by Daniel
171    o various changes to mnc including:
172      - all files use the new "BASENAME[[.ITER].{t|f}NUM].nc" format
173      - output can now be grouped so that all files within a group
174          change the ITER portion of their names in lock-step together
175      - can now read ("global") PER-FACE (in addition to PER-TILE) files
176          and works with both EXCH1 and EXCH2 (but needs more testing)
177      - writing works for all verification test cases w/ g77 on Linux
178    
179    checkpoint57r_post
180    o make MNC variable initialization happen earlier
181    o add diagnostics for (almost) each term of the momentum Eq.
182    o remove SST,SSS,UVEL_k2,VVEL_k2 diagnostics.
183    o move pkg timeave out of pkg-groups "oceanic" & "atmospheric" (pkg/pkg_groups)
184    o remove MINIMAL_TAVE_OUTPUT option ;
185      add "dumpInitAndLast" to replace "nodumps" (and MINIMAL_TAVE_OUTPUT).
186    o move some basic S/R (used elsewhere in the code) from pkg/mdsio to eesupp/src
187      allows to compile without pkg/mdsio (& test successfully hs94.1x64x5)
188    o add MNC output for adjoint of EXF (adexf), SEAICE (adseaice)
189    o add time-dependent SST, SSS control
190    o cost terms in ecco/ modularized (new cost_generic.F)
191    o cost_averages routines are modularized (new cost_averagesgeneric.F)
192    o new infrastructure for seaice model vs. obs misfits in seaice/
193      * driver from the_main_loop.F is seaice_cost_driver.F
194      * first term is AREA vs. SMR observation misfit (ALLOW_SEAICE_COST_SMR_AREA)
195      * gradient check in Exp. 6a of natl_box_adjoint/
196    o natl_box_adjoint input_seaice for Lab. Sea now available online via wget
197      (see README file)
198    
199    checkpoint57q_post
200  o fix initialisation Pb in calc_gw (get NANs in exp5 with g77)  o fix initialisation Pb in calc_gw (get NANs in exp5 with g77)
201  o fix annoying months-old bug in mnc/mdsio output for seaice pkg  o fix annoying months-old bug in mnc/mdsio output for seaice pkg
