4      Notes on tags used in MITgcmUV      Notes on tags used in MITgcmUV
5      ==============================      ==============================
6    
7    o fix the pickup behavior for obcs in combination with ptracers
8    o fix a bug in ptracers_external_fields_load
9    o no AB-2 at the first iteration for Gw (consistent with Gu,Gv,Gt,Gs ...)
10      affects results of NH experiments (but all our NH tests have Gw[it=1]==0 !!)
11    o transfered surface NH pressure to eta field (if exactConserv).
12    o gmredi: fix bugs in slope tapering ldd97 (depthZ had the wrong sign)
13         and update lab_sea output.txt file.
14    o completing 3-dim. relaxation code: additional term
15         1/tau*( theta(i,j,k) - thetaStar(i,j,k) )
16      in S/R EXTERNAL_FORCING_T (file external_forcing.F)
17      * At compile time, in "EXF_OPTIONS.h" set
18          #define  ALLOW_CLIMTEMP_RELAXATION
19          #define  ALLOW_CLIMSALT_RELAXATION
20      * At runtime in "data", under &PARM03 set (e.g., units in seconds)
21          tauThetaClimRelax3Dim = 15552000.0,
22          tauSaltClimRelax3Dim  = 15552000.0,
23      * 3 cases:
24          1) Use a constant-in-time 3-dim. field
25          2) Provide 12 3-dim. fields corresponding to Jan., ... , Dec.
26          3) Real-time relax. to time-evolving prescribed field
27    
28    checkpoint57y_post
29    First step for a NLFS adjoint
30    o initially suppress rStar (new flag DISABLE_RSTAR_CODE)
31    o new init. routines for calc_r_star, calc_surf_dr
32    o still need to deal with ini_masks_etc
33    o testreport seemed happy
34    checkpoint57y_pre
35    
36    o obcs: always reset wVel & eta (to zero or prescribe it) at the OBs.
37    o add new package rbcs (for relaxing ptracers at boundaries/depth/surface etc)
38    o add new offset feature to offline pkg (plus minor cleanup)
39    o cfc fixes for final year of integration
40    o clean up GCHEM_OPTIONS.h/DIC_OPTIONS.h (all options should
41      be in GCHEM_OPTIONS).
42    
43    checkpoint57x_post
44    o fix testreport Pb in multiple test experiment.
45    o cleanup our namelist syntax in verification:
46      - make it more F95 standards compliant (some work still needed)
47      - allows the vast majority of our tests to work with gfortran
48    o Non-Hydrostatic:
49     - put all NH variables (formerly in DYNVARS.h & GW.h) in NH_VARS.h
50     - fix exchange calls for CS-grid using the new EXCH_S3D_RL.
51    o Allow to apply AB on T,S rather than on AB(gT,gS):
52     - implemented within #ifdef ALLOW_ADAMSBASHFORTH_3
53     - use the same arrays (gtNm,gsNm) to hold tracer field at previous
54       time-steps (if AB(T,S)) and tendencies (if AB(gT,gS)).
55     - need a "clever" read_pickup to restart from the other AB formulation
56    o move local commom bloc /GlobalLo/ (used for singleCpuIO) in EESUPPORT.h
57    o remove some unused variables (reduces number of compiler warnings)
58    o adjoint
59      * Disable useVariableViscosity for adjoint for time being
60        (there are a number of extensive recomputations)
61      * Initialize certain variables needed for adjoint
62    
63    checkpoint57w_post
64    o pkg/mdsio: use MAX_LEN_FNAM (instead of hard coded 80) for file-names
65                 fix the singleCpuIO RS version of MDSWRITEFIELD
66       and add a WARNING if using globalFiles=T with multi-processors.
67    o write grid-file(s) in only one format (MDS or MNC): default=MNC (if
68      using MNC); can force MDS output by setting writegrid_mnc=F in data.mnc
69    o tracer advection scheme:
70      add DST-2 (=Lax-Wendroff) & 1rst order upwind schemes (the way to get
71       those 2 schemes before, changing GAD_FLUX_LIMITER.h + to recompile,
72       was not very convenient).
73      add implicit version for DST-3 & DST3_Flux_Limit vertical advection;  
74       (further tests needed for the implicit DST & Flux-Limiter schemes).
75    o PTRACERS: added namelist parameter PTRACERS_ref in analogy to tRef
76      and sRef for convenience, handy, when you want to initialize
77      ptracers in a large domain with a constant non-zero value. Also,
78      untangle ptracers_init.F a little.
79    
80    checkpoint57v_post
81    o change dome exp. to use variable viscosity in side-drag terms.
82    o remove all the files from the cfc_offline test since they are now
83      incorporated into tutorial_cfc_offline which has been producing
84      identical results for a few days of testing
85    o add new parameter: sideDragFactor to enable half-slip-side BC
86      and change side-drag S/R to use viscosity from mom_calc_visc
87      (can switch back by setting sideDragFactor=0.); affects results at
88      truncation level; regenerate output for exp.: global_ocean.cs32x10(x3),
89       global_ocean_ebm, global_ocean_pressure, matrix_example & MLAdjust(x5).
90    o vorticity & strain are now computed without masking, to account for
91      no-slip-side BC in variable viscosity calculation ; mask is applied
92      anyway later on, before computing advection/coriolis terms.
93    o modify exp4 to test new obcs support for reading from external files
94      and for passive tracers
95    o fix behavior of ptracers_monitor when monitor output is written to a
96      netcdf-file; still not independent of monitor.F (writes in the same
97      file).
98    o change default value of tRef (put a uniform, meaningful value for ocean
99      & atmos) and initialize sRef (was missing, as Martin mentioned).
100    o Redefine viscC?Leith*.  Change the coefficients of Leith viscosity
101      to be proportional to enstrophy dissipation length.  Thus,
102       viscC?leith?_new=pi*(viscC?leith?_old)^(1/3)
103      This is now consistent with Smagorinsky and with the manual.
104    
105    checkpoint57u_post
106    o OBCS and PTRACERS: add open boundary support for passive tracers
107      - either use homogenous (pseudo) v.Neumann conditions or prescribe
108        OB-values from file; this is not different from the way theta and salinity
109        are treated
110      - however, Orlanski-radiation conditions are not supported, and the model
111        will stop if you use pTracers and Orlanski at the same time.
112      - beefed up the rountine obcs_external_fields_load: now only those open
113        boundary values are overwritten with values from files for which there
114        are really files, otherwise the OB-fields remain untouched. This makes
115        it possible to use different OBs at different ends of the domain (as
116        with EXF)
117    o reduce number of exch calls in shap_filt (s2).
118    o CS-grid: fix divergence contribution to Leith viscosity. Affects (@
119      truncation level) 4/5 MLAdjust test results (11&12 digits match).
120    
121    checkpoint57t_post
122    o test biharmonic viscosity + no-slip with exp: global_ocean.cs32x15.viscA4
123    o finish adding brackets (coriolis S/R, vecinv) in multi-terms sum to get
124      same truncation, independent of the face number: affects affects several
125      test. exp.: Update global_ocean.cs32x15 (+.thsice) & MLAdjust (all 5).
126    o fix bug in mom_v_sidedrag (biharmonic viscosity was counted 2 times);
127      note that biharmonic viscosity + no-slip was not tested in any experiment.
128    o fix bug in non-linear free-surf side-drag ; generate new output for
129      global_ocean.cs32x15(+.thsice) & global_ocean_pressure.
130    o make mnc honor the writeBinaryPrec flag for most kinds of output
131    o eesupp: split EEPARAMS into EESIZE/EEPARAMS and add a vector global sum
132    o minor change in averaging W (mom_vi_?_vertshear.F) that affects truncation
133      error; update output from global_ocean.cs32x15(+.thsice) & MLAdjust (all 5).
134    o add brackets in multi-terms sum to get same truncation, independent of
135      the face number (manage to get exactly same value of gU,gV at the cs-edge)
136      affects several test. exp. Update global_ocean.cs32x15 (+.thsice).
137    o Clean, new version of mom_calc_visc.  Adds a new feature, viscAhRemax
138      and viscA4Remax, which allow one to limit the minimum viscosity by specifying
139      a maximum grid-scale Reynolds number.  Also, changes all length calculations
140      in the case of grid anisotropy to geometric mean of dx**2 and dy**2.
141      Suggested values of viscosity parameters found in mom_calc_visc.
142      Many new viscosity diagnostics available.
143    
144    checkpoint57s_post
145    o Add clearing-house for viscosity calculations, mom_calc_visc and
146      correct numerous bugs in LeithD and Smagorinsky discretizations.  
147      mom_calc_visc now allows for Smagorinsky, Leith and LeithD to be
148      used simultaneously, and to be used in mom_vecinv and mom_fluxform.
149      Mom_vecinv can be used with standard viscous calculation (mom_vi_hdissip.F)
150      and with Strain-Tension viscous term calculation (mom_hdissip.F).  
151      The Strain-Tension form is now called with useStrainTensonVisc=.true.
152      ViscAhStrain and viscAhTension are now retired.
153    o diagnostics "VISCAHD" & "VISCA4D" replace "VISCAH" & "VISCA4".
154    o In response to JMC's bug report, genmake2 now ignores any soft-links
155      that it finds in the *current* directory when searching for files.
156      Soft-links found in any other source directories will still work as
157      they did before.
158    o add HAVE_SETRLSTK define and useSETRLSTK flag (eedata) which calls
159      a C routine to unlimit the stack size
160    o mnc-ify pkg/aim snapshot vars
161    o mnc-ify pkg/land as requested by Daniel
162    o various changes to mnc including:
163      - all files use the new "BASENAME[[.ITER].{t|f}NUM].nc" format
164      - output can now be grouped so that all files within a group
165          change the ITER portion of their names in lock-step together
166      - can now read ("global") PER-FACE (in addition to PER-TILE) files
167          and works with both EXCH1 and EXCH2 (but needs more testing)
168      - writing works for all verification test cases w/ g77 on Linux
169    
170    checkpoint57r_post
171    o make MNC variable initialization happen earlier
172    o add diagnostics for (almost) each term of the momentum Eq.
173    o remove SST,SSS,UVEL_k2,VVEL_k2 diagnostics.
174    o move pkg timeave out of pkg-groups "oceanic" & "atmospheric" (pkg/pkg_groups)
175    o remove MINIMAL_TAVE_OUTPUT option ;
176      add "dumpInitAndLast" to replace "nodumps" (and MINIMAL_TAVE_OUTPUT).
177    o move some basic S/R (used elsewhere in the code) from pkg/mdsio to eesupp/src
178      allows to compile without pkg/mdsio (& test successfully hs94.1x64x5)
179    o add MNC output for adjoint of EXF (adexf), SEAICE (adseaice)
180    o add time-dependent SST, SSS control
181    o cost terms in ecco/ modularized (new cost_generic.F)
182    o cost_averages routines are modularized (new cost_averagesgeneric.F)
183    o new infrastructure for seaice model vs. obs misfits in seaice/
184      * driver from the_main_loop.F is seaice_cost_driver.F
185      * first term is AREA vs. SMR observation misfit (ALLOW_SEAICE_COST_SMR_AREA)
186      * gradient check in Exp. 6a of natl_box_adjoint/
187    o natl_box_adjoint input_seaice for Lab. Sea now available online via wget
188      (see README file)
189    
190    checkpoint57q_post
191    o fix initialisation Pb in calc_gw (get NANs in exp5 with g77)
192    o fix annoying months-old bug in mnc/mdsio output for seaice pkg
193      - bug was reported by Jean-Michel and Ian Fenty
194    o fix initialization Pb in AIM-Ocean coupled model (aim_sice2aim.F)
195      update exp. cpl_aim+ocn output.
196    o Implement 4-level checkpointing: AUTODIFF_4_LEVEL_CHECKPOINT
197      Needed for high-res. runs with large global files
198      to be able to limit tapelev size
199    o Changed some tests for adjoint:
200      * carbon/ now tests AUTODIFF_2_LEVEL_CHECKPOINT
201      * natl_box_adjoint/code_bulk/ tests AUTODIFF_4_LEVEL_CHECKPOINT
202      * global_ocean.90x40x15/ back to default 3-level checkpointing
203    o Modifications to enable scripted COMMON to MODULE conversion
204      * verification/OpenAD/code/ has necessary scripts and description;
205      * converts, compiles and runs successfully;
206    
207    checkpoint57p_post
208    o reading of delXfile & delYfile moved from ini_parms.F to ini_grid.F
209    o move ${PKG}_MNC_INIT from ${PKG}_READ_PARAMS to ${PKG}_INIT_FIXED
210      (already the case for some pkgs, including recent MNC_init, e.g. thsice)
211    o call CALC_GW from DYNAMICS (instead of from FORWARD_STEP)
212    o Dissipation & phiHyd gradient are always added to gU,gV in timestep.F
213      (was already the case for dissipation with mom_vecinv,
214       and also the case for grad.PhiHyd when staggered-timeStep)
215      This will allow to put dissipation out-off the AB time-stepping.
216     Unfortunately, affects truncation error. Update output of exp. that "fails"
217      (cg2d matching number) and leave the others for later: front_relax(10),
218      global_ocean_pressure(10),ideal_2D_oce(10),internal_wave(9),lab_sea(12),
219      matrix_example(7!),natl_box(12),plume_on_slope(11),vermix(12x3,11x2).
220    
221    checkpoint57o_post
222  o fix MNC/MDSIO flags in PTRACERS so that (1) it works, and  o fix MNC/MDSIO flags in PTRACERS so that (1) it works, and
223    (2) its ready to be documented during the 20050801 DocFest    (2) its ready to be documented during the 20050801 DocFest
224  o MNC-ify the gmredi package -- tested and works w/ and w/o mnc  o MNC-ify the gmredi package -- tested and works w/ and w/o mnc
225    for ideal_2D_oce and lab_sea on linux_ia32_g77    for ideal_2D_oce and lab_sea on linux_ia32_g77
226    o set to #undef CTRL_SET_OLD_MAXCVARS_30
227      in global1x1_tot/code_seaice_adj to access indices 32, 33
228      (worth another tag)
