3      Notes on tags used in MITgcmUV      Notes on tags used in MITgcmUV
4      ==============================      ==============================
5    o faulks upgraded: re-generate output.txt that have changed:
6       global_ocean.cs32x15(.thsice), global_ocean_ebm, lab_sea, natl_box
7    o Added Bryan and Lewis, 1979, vertical diffusivity profile
8    o pkg/land: fix problem in land_impl_temp.F when Ts arround freezing.
9    o added Sadourny discretization of Coriolis
10      - moved some PARAMETERS from mom_*_coriolis.F to PARAMS.h
11      - re-enabled use of omega3 (useAbsVorticity)
12    o added Leith (Phys. Fluids, 1968, 10, 1409-1416) variable viscosity for
13      vector-invarianet equations
14      - note: does *NOT* yet use same variable visc. for no-slip BC's.
15    o recoded the lateral boundary conditions for non-hydrostatic w, this time
16      hopefully without new bugs
17      - still to do: biharmonic friction for non-hydrostatic w
18    o bug fix for mom_*_sidedrag: rA -> rAs,rAw
19    o regenerated output for global_ocean_ebm (using -ieee)
20    o fix mom_common/mom_*_sidedrag.F to recover numeric output prior to creation
21      of mom_common/
22      - simple re-arrangement of instructions within computing loop
23    checkpoint53d_pre
24    
25    checkpoint53c_post
26    o new version of coupler for AIM+thSIce and Ocean models
27     - new fields (SSS,h_MixLayer ...) are exchanged through the coupler
28     - land: change Evaporation of snow
29     - aim with thSIce: fix bug in snow-precip.
30    o changes to calc_gw.F
31     - bug fix for w^2 term near the bottom boundary
32     - (hopefully) improve the lateral slip boundary condtions for use with
33        partial/looped cells
34      - because the bug fix changes two verification experiments anyway (exp5
35        and plume on slope), change the lateral boundary condition from half slip
36        to the value of no_slip_sides
37    o ebm package wasnt quite up to the parallel task. Fixed that.
38    o Adjoint of EBM package + verification
39      * TLM OK
40      * ADM not sufficient accuracy yet (needs further testing)
41    
42    checkpoint53b_post
43    o Commiting new energy balance model to repository
44      * package is pkg/ebm
45      * verif. is verification/global_ocean_ebm
46      * references are in ebm_driver.F
47    C      * X. Wang, P. Stone and J. Marotzke, 1999:
48    C        Global thermohaline circulation. Part I:
49    C        Sensitivity to atmospheric moisture transport.
50    C        J. Climate 12(1), 71-82
51    C      * X. Wang, P. Stone and J. Marotzke, 1999:
52    C        Global thermohaline circulation. Part II:
53    C        Sensitivity with interactive transport.
54    C        J. Climate 12(1), 83-91
55    C      * M. Nakamura, P. Stone and J. Marotzke, 1994:
56    C        Destabilization of the thermohaline circulation
57    C        by atmospheric eddy transports.
58    C        J. Climate 7(12), 1870-1882
59    o Will need long integration testing.
60    checkpoint53b_pre
61    
62    o created pkg/mom_common in preparation for variable viscosity code
63    o renamed and split ini_mnc_io
64    o pkg/land: only liquid water can diffuse or run-off
65    o AIM using land: soil wetness availability account for snow
66    o added printMapIncludesZeros to EEPARMS namelist
67    
68    checkpoint53a_post
69    o restore TAMC compatiility for exf_constants.h
70      (no usage of _d in .h)
71    o Additional storing in KPP in an attempt to fix
72      TAMC problem with adjoint of KPP code.
73      (no success...)
74      Identical code works fine with TAF.
75    o Fixed verification/natl_box_adjoint experiments.
76      Initial conditions for Experiments 4 and 5 are now
77      set to "SEAICE_initialHEFF=0", which is more reasonable,
78      and hence gives results closer to that of Experiment 2.
79      Experiment 6 requires "SEAICE_initialHEFF=1" and is working once again.
80    
81    checkpoint53
82    o stable checkpoint with up to date adjoint
83      TLM tests only run for 1st grdchk at the moment. Its unclear if
84      this is a code problem or a problem with resetting code for g_
85      variables that is being autogenerated wrong.
86      Otherwise:
87       o code is testing well on Linux (P4 and AMD), SGI Alitix and Irix.
88       o IBM and HPQ tests could not be run because NCAR (IBM) and NCCS (HPQ)
89         are both still in chaos following their security messes.
90    
91    checkpoint52n_post
92    o various build (mostly genmake2) changes including:
93      - ability to build/run more easily within Cygwin and MacOS X
94      - more complicated Makefiles with a stronger dependence on Gnu Make
95    o pkg/seaice modifications
96      - added SEAICE_deltaTtherm and SEAICE_deltaTdyn in order to reduce cost
97        of pkg/seaice.  For time being, SEAICE_deltaTtherm = deltaTtracer
98        and SEAICE_deltaTdyn must be integer multiple of SEAICE_deltaTtherm
99      - changed proxy for geostrophic velocity and updated
100        verification/lab_sea/results/* accordingly
101      - removed ADI dynamic solver from pkg/seaice
102      - replaced all occurrences of 1/CSTICE or 1/CSUICE
103        they caused a segmentation fault under certain circumstances
104      - removed unused field WATR
105    o bug fix in exf-package:
106      -  u/vwind are defined at tracer/pressure points. The values of u/vwindmask
107         now reflect that.
108    o small fixes in the cal-package:
109      - set reference date to first of January for the 'model'-calendar
110      - failing of cal_CheckDate in cal_FullDate now actually results in a
111        warning
112    o small modifications in exf-package to increase flexibility:
113      - change climtempfreeze from a constant to a runtime parameter that
114        is specified in data.exf_clim (default = -1.9)
115      - introduce runtime parameter windstressmax (default = 2.0) that is
116        specified in data.exf
117    o fix in pkg/thsice:
118      - update Evap (Tsf changes) to be consistent with Latent heat flux
119      - maintain snow precipitation unchanged (even if Tsf >=0).
120     both affect global_ocean.cs32x15/(.thsice) results ; update output.txt.thsice
121    
122    checkpoint52m_post
123    o commented out call to cal_GetMonthsRec in swfrac.F and added some comments;
124      this does not change any of the results, because myIter=0 in swfrac always
125      lead to jwtype=2 (the default anyway), but the call makes little sense
126      as a default
127    o no SHORTWAVE HEATING lost at the bottom; affects lab_sea output; updated
128    o re-work pkg/thsice interface with ocean & bulk_force pkg to allow
129      atmospheric model (AIM) to use it ; add a "slab ocean" component.
130    o pkg/aim_v23 : add interface to call thermodynamic sea-ice (thsice)
131    o update global_ocean.cs32x15/output (.thsice) after changes in pkg/thsice
132    o extending useSingleCpuIO option to work with new exch2 I/O format
133      - old-style, missing-tile I/O is still accessible by defining CPP
134        option MISSING_TILE_IO in pkg/mdsio/MDSIO_OPTIONS.h
135    o monitor package can write to NetCDF files and/or STDOUT
136    o fix re-definition bug in MNC_GRID_INIT_ALL()
137    o doc/api_reference added
138      - a framework for building an API Reference Manual using all
139        the "protex" comments embedded in the code
140      - see pkg/generic_advdiff, pkg/mnc for examples
141    o MNC:
142      - make myThid the last argument for all subroutines
143      - new default for the grid files: NO halos
144      - add useMNC and other run-time flags
145      - separate per-file-group handling of the unlimited dimension
146      - early initialization of MNC w/ flags read at the eeboot stage
147        and lookup tables set in initialize_fixed
148      - write all MNC output to a freshly-created directory
149    o thermodynamics sea-ice (thsice) is now tested with testreport.
150    o test exp. advect_cs: use the standard cs32 grid ; update output.
151    o Added functionality to grdchk:
152      pick global i,j,k position (or nearest wet) where to perform check.
153    
154    checkpoint52l_post
155    o new land formulation:
156      a) use ground enthalpy as prognostic variable to ensure exact
157         energy conservation.
158      b) account for water temperature and for latent heat of freezing
159         in all processes (rain, run-off, ground storage)
160      c) compute surface and ground temperature implicitly.
161    o aim_v23 modification for new land model:
162      a) Treat separately land / ocean / sea-ice surface fluxes
163         to allow implicit computation of land & sea-ice surface temp.
164      b) add snow precipitation.
165    checkpoint52l_pre
166    
167    o fix problem (when 1 tile is empty) in min/max monitor.
168    o fix bug in timeAve (u,vZetatave in common block)
169    o no restoring terms under ice for pkg/seaice
170    o moved SEAICE_DO_DIAGS to S/R do_the_model_io
171    o bug fix for pkg/seaice pickups
172    o change MNC call locations and add coordinate attributes
173    o mask vorticity at the corner ; affects global_ocean.cs output
174    o fix ini_curvilinear_grid ; test CS experiments with mpi
175    o aim.5l_cs: modify sea-ice fraction input file ; update output
176    o exf: Adding simple range check routine for exf fields after read
177    
178    checkpoint52k_post
179    o removed top-level directory "diags"
180      - we migrated these functions to pkg/timeave a long time ago
181    o fixed bug introduced in pkg/monitor
182    o accuracy ctrlprec = 32 insuffient for gradient checks using
183      averaged fields (I/O via cost_averages)
184      -> use ctrl.h in active_file*.F to control I/O precision.
185    o paramter list of CALL ADTHE_MAIN_LOOP
186    o added initial do_the_model_io to ecco
187    o set all ...Freq to zero after cost_final
188      taveFreq, dumpFreq, pChkptFreq
189    o MAIN and ECCO differentiability restored
190    
191    checkpoint52j_post
192    o fix nchklev in tamc.h for global_ocean...
193    o Bringing flow and store directives up-to-date
194    o Really weird thing!
195      call do_the_model_io from the_main_loop with parameters
196      starttime, niter0, instead of mytime, myiter, screws up the adjoint:
197      TAF places a faulty re-call of initialise_varia
198      after cost_final call which should not be there!
199    checkpoint52j_pre
200    
201    o tweaked pkg/mdsio/mdsio_readfield.F to have more useful logic and
202      error messages
203    o fix errorMessageUnit problem. remove old version of mdsio from eesup/src
204    o modified pkg/mdsio/mdsio_readfield.F -- commented out diskspace-eating
205      debug output
206    o modfied mdsio_writefield.F to handle non-global files under exch2
207    o update AIM Cubed-Sphere exp (aim.5l_cs):
208      use land, p*, and Franco.M forcing fields with fractional land-sea mask.
209    o update AIM Equatorial Channel exp:
210      use standard aim_v23 pkg and change the SST fields to be more realistic.
211    o globalFile now works with exch2
212    o merged mom_vi_calc_relvort3.F, mom_vi_del2uv.F and
213      mon_vort3.F to make exch2 friendly with >1 tile per cube face
214    o limit timeave output for hi-res integrations
215    
216    checkpoint52i_post
217    o removed CPP_EEOPTIONS.h from verification/*/code
218    o updated the tiling for global_ocean_pressure
219    checkpoint52i_pre
220    
221    o update aim.5l_LatLon using the standard aim_v23 pkg (instead of
222      the old pkg/aim).
223    
224    checkpoint52h_pre
225    o shortened offending lines in exch2_send_rx?.template
226    o modified W2_EXCH2_TOPOLOGY.h to reflect current topology generator
227  o genmake2: add build & execute test for NetCDF code  o genmake2: add build & execute test for NetCDF code
228  o modded aim.5l_cs and global_ocean.cs32x15 to use exch2, removed  o modded aim.5l_cs and global_ocean.cs32x15 to use exch2, removed
229    old grid files, moved CPP_EEMACROS.h to pkg/exch2    old grid files, moved CPP_EEMACROS.h to pkg/exch2
230  o added useSingleCPUIO flag to monitor.F and mon_out.F  o added useSingleCPUIO flag to monitor.F and mon_out.F
231    o added temporary hack for sea-ice dynamics on the cube:
232      metric terms are ignored and it is assumed that
233      there is no sea-ice on cube faces 1, 2, 4, and 5.
234    
235  checkpoint52f_post  checkpoint52f_post
236  o added exch2 cube routines to pkg/exch2  o added exch2 cube routines to pkg/exch2
