4      Notes on tags used in MITgcmUV      Notes on tags used in MITgcmUV
5      ==============================      ==============================
6    
7  o change units of EmPmR (inside the code) from m/s to kg/m2/s (mass flux) but  o pkg/diagnostics: for large number of diagnostics, store diagnostic mate
8    leave input file unchanged. Affects results @ truncation level (cg2d match)    number in dedicate array "hdiag":
9    and update output of experiments: lab_sea(6), global_ocean.90x40x15(10),    - new version of S/R DIAGNOSTICS_ADD2LIST : DIAGNOSTICS_ADDTOLIST
10        with 1 more argument (mate number); modify old version DIAGNOSTICS_ADD2LIST.
11      - many small changes (integer format) for large number of diagnostics
12      - start to use DIAGNOSTICS_ADDTOLIST (necessary for diagnostics with
13        a counter mate) in pkg diagnostics, ptracers, thsice & aim_v23.
14    o add parameter rotateGrid and Euler angles EulerPhi/Theta/Psi. For
15      usingSphericalGrid, this allows to define the rotated grid coordinates
16      via phiMin/thetaMin/dxSpacing/dySpacing, etc., but then re-compute the
17      geographical coordinates according to the inverse of the rotation defined
18      by the Euler angles, so that Coriolis parameter and online-interpolation by
19      exf works with the geographical coordinates on XC/YC/XG/YG.
20      Naturally, this feature does not work with all packages, so some
21      combinations are prohibited in config_summary (flt, flt_zonal, ecco,
22      profiles), because there the coordinates are assumed to be regular
23      spherical grid coordinates.
24    o pkg/gmredi,ctrl,ecco,autodiff,grdchk and model/src,inc:
25      - introduce isopycnal diffusion coefficient control.
26    o tools/adjoint_options:
27      - additional control vector components.
28    o pkg/mnc: have mnc create marginally meaning full coordinate variables
29      (that is the grid indices) if usingCurvilinearGrid and NOT EXCH2
30    o pkg/mypackage:
31      - add example of read/write pickup for state-var ;
32      - add entry points to the main code for state-vars diags & write-pickup.
33    o pkg/exf: rewrite of exf_getffieldrec.F to properly deal with year
34      transitions for useExfYearlyFields
35      - add new subroutine that determines the file to read from for
36        use*YearlyFields = .TRUE. and .FALSE.
37      - add a verification experiment to global_with_exf that tests
38        useExfYearlyFields with USE_EXF_INTERPOLATION defined
39    o pkg/obcs/exf: add useOBCSYearlyFields (=.FALSE.) to obcs with exf in
40      analogy to useExfYearlyFields; rearrange obcs_prescribe_read: two new
41      subroutines (which could be generated from a template, because they are
42      almost identical), for now they are included in obcs_prescribe_read.F for
43      simplicity
44    o pkg/exf:
45      - add a little more diagnostic to exf_interp_read (in analogy to
46        mds_read_field, can be turned off with debugLevel < debugLevA=1)
47      - improve vectorizability of exf_interp for TARGET_NEC_SX, makes code
48        ugly but fast by unrolling short inner loops, inserting a unroll=8
49        directive in routine lagran, and splitting a loop and making do while the
50        outermost loop (the latter requires the intoduction of index arrays)
51    o pkg/obcs: replace obcs_apply_area/heff/hsalt/hsnow with obcs_apply_seaice
52    o pkg/seaice: moved DIFFERENT_MULTIPLE from seaice_model to seaice_dynsolver
53      http://forge.csail.mit.edu/pipermail/mitgcm-devel/2008-January/003173.html
54    o verification/seaice_obcs: updated for restart test and latest options
55    o pkg/seaice: add a new flag SEAICEuseTEM to use a slightly different
56      ice rheology (so-called truncated ellipse, that gets rid of tensile stress);
57      for now this is only available for the C-grid code and also within
58      #ifdef SEAICE_ALLOW_TEM, because this option may slow down the EVP code
59    
60    checkpoint59m
61    o pkg/seaice: use different time constant for melting (SEAICE_gamma_t)
62      and freezing (SEAICE_gamma_t_frz) ice due to mixed layer temperature
63    o gad_som : fix flux output (& diagnostics) to have same units as other  
64      advection scheme fluxes (was previously multiplied by deltaT).  
65    o added verification/seaice_obcs both to test seaice open boundaries
66      and to provide an example matlab scrpt for generating them
67    o added verification/lab_sea/input.salt_plume for testing pkg/salt_plume
68    o pkg/salt_plume: clean up salt_plume_frac.F to
69      remove redundancy in PlumeMethod 1 and 4
70    o pkg/kpp: added saltplume diagnostics
71    o pkg/obcs and pkg/seaice:
72      - do not set uice and vice to zero when OB*icefile are unspecified
73      - OBCS_SEAICE_AVOID_CONVERGENCE is undefined by default
74      - moved seaice tracer obcs after call to seaice_growth
75    o pkg/salt_plume: added various options for salt plume depth
76      criterion and for vertical distribution of the salt
77    
78    checkpoint59l
79    o pkg/ptracers: new version of ptracers pickup:
80      read meta file and write only fields which are needed to restart.
81      ( same logic as main pickup file ; also using pickupStrictlyMatch )
82    o pkg/seaice:
83      - add timescale for melting due to warm mixed layer as a means of
84        setting SEAICE_availHeatFrac more conveniently
85      - add a CPP-flag/runtime parameter check for flooding algorithm
86      - reformulated availHeat in seaice_growth.F to be independent of AREA
87    o change units attribute of EmPmR netcdf variables to kg/m^2/s to reflect recent
88      unit changes
89    o pkg/obcs: added OBCS_SEAICE_AVOID_CONVERGENCE constraint
90    o cg2d.F: add 3 compiler directives that speed up this routine by 30% on a NEC
91      SX vector computer.
92    o pkg/seaice:
93      - removed SEAICE_FFIELDS.h and seaice_get_forcing.F
94        seaice forcing fields can now be read only through pkg/exf
95      - removed some unused halos
96    o no longer write pickup from THE_MODEL_MAIN but always from FORWARD_STEP
97    o pkg/exf: added useRelativeWind EXF_PARAM.h option for subtracting U/VVEL
98      or U/VICE from U/VWIND before computing U/VSTRESS
99    
100    checkpoint59k
101    o pkg/seaice: ICE2WATR=SEAICE_rhoIce/rhoConst for consistency between
102      dynamics and thermodynamics. Set ICE2WATR=0.92 to reproduce older results.
103    o fix un-initialised variable problem (in mom_vecinv & shap_filt):
104      all experiments pass when compile with un-initialised var. checking option.
105    o added pkg/salt_plume
106    o script to test restart (for now, in MITgcm_contrib/jmc_script)
107    o pkg/seaice: new read/write pickup version.
108      read meta file and write only fields which are needed to restart.
109      ( same logic as main pickup file ; also using pickupStrictlyMatch )
110    o pkg/seaice: fix bug in seaice_ocean_stress (call of seaice_calc_strainrates)
111    o lab_sea.hb87: modify the domain & update output.hb87.txt :
112      lat-long grid & no-slip BC in seaice-dynamics produce different sigma12
113      at j=1 & j=Ny+1 : this case is not treated correctly in the restart
114      process. Fixed here by closing the domain at the Northern boundary.
115    o pkg/rw: cleaning-up: call directly new MDSIO S/R MDS_READ/WRITE_FIELD.
116    o pkg/mdsio: add new arguments to MDS_READ/WRITE_FIELD for reading/writing
117      a set of consecutive levels in/from a 3-D array.
118    o pkg/ptracers:
119      use a 2 characters string ioLabel to identify tracer (if more than 99 tracers).
120      to-do: fix pkg/diagnostics when large number of diagnostics are defined.
121    
122    checkpoint59j
123    o in pkgs: dic, obcs, offline, rbcs:
124      standard way to compute coeff. for time interpolation between 2 time reccords
125      which retains full precision (& make results less dependent on compiler).
126      update output of exp: tutorial_cfc_offline & tutorial_global_oce_biogeo.
127    o pkg/cfc: if compiled with exf and seaice, cfc now can use fields from those
128      packages instead of reading ice cover and wind speed separately
129    o split PTRACERS.h in 2 header files: PTRACERS_FIELDS.h & PTRACERS_PARAMS.h
130     (keep a temporary version of PTRACERS.h in verification/OpenAD/code_ad_openad
131      to allow to compile customized code before the update)
132    o cleaning-up:
133      - fix CPP instruction syntax in pkg/obcs
134      - replace (some) call to MDSIO S/R with call to RW interface S/R ; and
135        add #ifdef ALLOW_MDSIO elsewhere (allows to compile without pkg/mdsio)
136      - fix some threads issue in IO parts.
137    o pkg/dic:
138      - add tons of "_d 0" (--> much better testreports !)
139       and then update outputs of tutorial_global_oce_biogeo
140    o pkg/mom_fluxform:
141      add a special version of momentum advection intended to conserve momentum
142      next to a bathymetry step or a coastline edge. (default = off = #undef)
143    o new read/write pickup version:
144      - for now, only implemented for main (mdsio) pickup file.
145      - write out only what is needed to restart; merge pickup_nh , pickup_ph
146        and main pickup together.
147      - read meta file; read only what is needed to restart; stop if a field
148        is missing (if pickupStrictlyMatch=T, = the default) or try to restart
149        if it make sense (even if the restart is not perfect).
150      - if no meta file, assume that pickup to read corresponds exactly to
151        a pickup that would currently be written.
152      - read pickup written in the old format (until checkpoint59i) if it
153        recognizes an old meta file (no field-list).
154      - add a meta file in exp. which starts from a pickup: 2 cases:
155        a) minimal meta file (with just file precision) + pickupStrictlyMatch=F
156         e.g.: global_ocean.90x40x15/input/pickup.0000036000.meta
157        b) a meta file describing the content of the associated pickup file
158         e.g.: tutorial_global_oce_biogeo/input/pickup.0004248000.meta
159    o pkg/mdsio & pkg/rw:
160      - new routine to read a meta file ; new set of routine to read
161        Multiple-fields file (with meta file).
162    o added open boundary conditions capability for seaice
163        HSNOW, HSALT, UICE, and VICE
164    
165    checkpoint59i
166    o adjoint:
167      * fix multiDimAdvection adjoint
168        (partial recomputation problem by TAF for fVerT(:,:,kDown)
169        and comlev1 size definition (maxpass vs. max. number of tracers)
170      * verification/global_ocean.90x45x15 adjoint now tests
171        NLFS and multiDimAdvection using DST3 (=30)
172      * verification/lab_sea now tests multiDimAdvection using DST3 (=30)
173    o pkg/kpp: add "_d 0" to real constant (if missing);
174      update output of exp: natl_box (10.digits); vermix (std, 7.digits)
175      and lab_sea, 3.FW (only 6,4,6 digits match) & AD (8.digits).
176    o prepare for "clever pickup" implementation: add new header file "RESTART.h"
177      for internal parameters related to restart process (formerly from PARAMS.h)
178      and add startAB parameter to argument list of S/R ADAMS_BASHFORTH2.
179    o more standard interface to {PKG}_WRITE_PICKUP with pickup suffix passed
180      as argument. (only atm2d & obcs write_pickup have not yet been updated)
181    o pkg/monitor:
182      - use GLOBAL_SUM_TILE instead of _GLOBAL_SUM
183      - fix mon_stats_rs (statistics over the full domain, even where field is zero)
184      - account for deep Atmosphere factor and density factor (anelastic)
185    o added open boundary conditions capability for seaice HEFF and AREA
186    o pkg/shelfice: add option for convservative form of Hellmer&Olbers (1989)
187      thermodynamics
188      - requires a little reorganization, which affects the testreport results
189        of isomip.htd (only 7 digits of cg2d agree) => update/modify experiment,
190        so that now the conservative form is tested
191      - add a few comments
192    o add missing cvs Header: or Name: in eesupp/*, pkg/* & verification/code*
193    o add a little bit of code to gad_os7mp_adv_?.F to help vectorization
194    o add new diagnostics to seaice: advective, diffusive fluxes (only for
195      multidim-advection, for scheme 2 they are not filled) and transports,
196      thermodynamic growth rates
197    o change units of EmPmR (inside the code, + within coupling interface)
198      from m/s to kg/m2/s (mass flux) but leave input file unchanged.
199      Affects results @ truncation level (cg2d match) and update output of
200       experiments: lab_sea(6), global_ocean.90x40x15(10),
201    global_ocean.cs32x15(11x3,10), natl_box(11), tutorial_global_oce_latlon(11)    global_ocean.cs32x15(11x3,10), natl_box(11), tutorial_global_oce_latlon(11)
202    + adjoint results: global_ocean_ebm(11) and lab_sea (12).    + adjoint results: global_ocean_ebm(11) and lab_sea (12).
203      Coupled set-up: allow to restart from previous pickups (cpl_oldPickup=T).
204    Next: will retire convertEmP2rUnit (simply using mass2rUnit instead).    Next: will retire convertEmP2rUnit (simply using mass2rUnit instead).
