4      Notes on tags used in MITgcmUV      Notes on tags used in MITgcmUV
5      ==============================      ==============================
6    
7    o remove "exp5" (replaced by tutorial_deep_convection).
8    o pkg/obcs: add code to fix topography gradients normal to open boundaries;
9      this requires computing the index fields OB_Jn/Js/Ie/Iw in obcs_readparms;
10      the code can be turned on by setting OBCSfixTopo = .true. in data.obcs
11      --> changes results in dome, exp4, internal_wave, seaice_obcs, and
12      tutorial_plume_on_slope.
13    o tutorial_deep_convection :
14      update the set-up and increase resolution and domain size ; start
15      from pseudo initial conditions = output at t=120mn in order to see
16      something happening when running testreport.
17    o pkg/seaice: add os7mp as an advection scheme
18                  add check for advection schemes
19                  add a flag for restoring T and S underneath sea ice
20    o pkg/my82: add netcdf-support and diagnostics
21    o thsice pkg:
22      - Now hsMax limits snow height by turning it into ice following
23        flooding scheme (and now conserving energy)
24      - Slight rewriting of the formula in thsice_calc_thick.F
25      - Parameter rhowi eliminated to be replaced by floodFac = (rhosw-rhoi)/rhos
26      --> changes results of global_ocean.cs32x15.icedyn and global_ocean.cs32x15.thsice
27    
28    checkpoint59p
29    o gchem / dic / cfc :
30      - add useDIC, useCFC , read from "data.gchem" (& hold in GCHEM.h);
31      - add new parameter files: "data.dic" & "data.cfc" ;
32      - various re-arrangement in initialisation & header file ;
33      - fix tutorial_global_oce_biogeo for multi-threaded test.
34    o pkg/dic: test for "pickup_dic" file when restarting ;
35      if no pickup-file, can restart with a re-initialised pH (same as it did
36      before) providing pickupStrictlyMatch is set to False.
37    o change argument list of S/R PTRACERS_WRITE_PICKUP & MYPACKAGE_WRITE_PICKUP
38      + fix call to S/R GGL90_WRITE_PICKUP & DIC_WRITE_PICKUP
39    o add a "warning" (to Error msg file) when an Active Tracer is not using AB-2
40      and staggerTimeStep is off (needed for stability of Internal-wave dynamics).
41    o move out of PARAMS.h & data the last pieces of old-ptracer code: tauTr1ClimRelax,
42     & lambdaTr1ClimRelax ; put those 2 params in PTRACERS_PARAMS.h & data.ptracers
43       (note: not clear to me what lambdaTr1ClimRelax is still used for ...)
44    o pkg/mom_vecinv: - new parameter "selectVortScheme" to select which
45       scheme to use for vorticty-term ;
46     - compute upwindVorticity=T case within mom_vi_u/v_coriolis_c4.F
47       (with default selectVortScheme, return to original discretisation)
48     - remove weird combination (e.g.: upwindVorticity & highOrderVorticity)
49    o pkg/seaice: add a line to the summary to indicate grid type (B/C)
50    o in mom_calc_visc, fix average value of viscAh_W & viscA4_W next to the
51      bottom ; only used with variable horizontal viscosity and non-hydrostatic.
52      also fix diagnostics VISCAHW & VISCA4W.
53    
54    checkpoint59o
55    o dome/code/obcs_calc.F: avoid division by zero (detected using gfortran).
56    o change the loop ordering in most gad_*_adv_x.F to improve vectorization:
57      move a few statemens out the main loop into separate loops
58    o pkg/shelfice:
59      - sort out freshwater flux; convert freshwater fluxes to mass fluxes
60        (kg/m^2/s), does not break tests, because in verification/isomip,
61        rhoConstFresh=rhoConst (by accident)
62      - rearrange computation of tLoc, sLoc, pLoc to make code more efficient
63      - move S/R find_rho_scalar, pkg/ecco/sw_ptmp.F, pkg/ecco/sw_adtg.F into
64        new file model/src/seawater.F, so that they are available for all pkgs.
65      - convert potential temperature into in-situ temperature. This changes the
66        isomip tests => update tests
67    o add a flag writePickupAtEnd (default=true) to be able to suppress
68      writing a pickup at the last timestep
69    o tools/mpack-1.6 :
70      - disable automake (not working) and autoconf (not needed).
71      - update to version 1.6.4 which fix MD5 code on some 64 bits platforms
72        also cleaner with much less compilation warnings.
73    o pkg/profiles:
74      rename profiles_interp_mean_genericgrid as profiles_interp_mean_gg
75      (for "less than 32 characters name" compiler requirement)
76    o pkg/obcs and pkg/exf: added capability to specify seaice open boundary
77      conditions that have a different sampling frequency than S/T/U/V obcs
78    o pkg/diagnostics (stats-diags):
79      - fix global Min/Max in case 1 processor get only empty tiles
80    o genmake2: replace (4 times)
81         make genmake_tc_1.o >> genmake_warnings 2>&1
82      with
83         COMM="$CC $CFLAGS -c genmake_tc_1.c"
84         echo $COMM >> genmake_warnings
85         $COMM >> genmake_warnings 2>&1
86      to make genmake2 always see the value of CC as specified in the optfile.
87    o generic_advdiff: - prather advection scheme (SOM) coded for CS-grid.
88      - add diagnostics for 1srt & 2nd Order moments and sub-grid variance.
89      - modify verification advect_cs test to test SOM-advection on CS-grid.
90    o pkg/ctrl:
91      - Rewrite of ctrl_map_ini_ecco.F,
92        introducing a generic routine (ctrl_map_ini_gen.F).
93      - Modification of ctrl_bound/adctrl_bound handling control vector bounds.
94    
95    checkpoint59n
96    o pkg/diagnostics: for large number of diagnostics, store diagnostic mate
97      number in dedicate array "hdiag":
98      - new version of S/R DIAGNOSTICS_ADD2LIST : DIAGNOSTICS_ADDTOLIST
99        with 1 more argument (mate number); modify old version DIAGNOSTICS_ADD2LIST.
100      - many small changes (integer format) for large number of diagnostics
101      - start to use DIAGNOSTICS_ADDTOLIST (necessary for diagnostics with
102        a counter mate) in pkg diagnostics, ptracers, thsice & aim_v23.
103    o add parameter rotateGrid and Euler angles EulerPhi/Theta/Psi. For
104      usingSphericalGrid, this allows to define the rotated grid coordinates
105      via phiMin/thetaMin/dxSpacing/dySpacing, etc., but then re-compute the
106      geographical coordinates according to the inverse of the rotation defined
107      by the Euler angles, so that Coriolis parameter and online-interpolation by
108      exf works with the geographical coordinates on XC/YC/XG/YG.
109      Naturally, this feature does not work with all packages, so some
110      combinations are prohibited in config_summary (flt, flt_zonal, ecco,
111      profiles), because there the coordinates are assumed to be regular
112      spherical grid coordinates.
113    o pkg/gmredi,ctrl,ecco,autodiff,grdchk and model/src,inc:
114      - introduce isopycnal diffusion coefficient control.
115    o tools/adjoint_options:
116      - additional control vector components.
117    o pkg/mnc: have mnc create marginally meaning full coordinate variables
118      (that is the grid indices) if usingCurvilinearGrid and NOT EXCH2
119    o pkg/mypackage:
120      - add example of read/write pickup for state-var ;
121      - add entry points to the main code for state-vars diags & write-pickup.
122    o pkg/exf: rewrite of exf_getffieldrec.F to properly deal with year
123      transitions for useExfYearlyFields
124      - add new subroutine that determines the file to read from for
125        use*YearlyFields = .TRUE. and .FALSE.
126      - add a verification experiment to global_with_exf that tests
127        useExfYearlyFields with USE_EXF_INTERPOLATION defined
128    o pkg/obcs/exf: add useOBCSYearlyFields (=.FALSE.) to obcs with exf in
129      analogy to useExfYearlyFields; rearrange obcs_prescribe_read: two new
130      subroutines (which could be generated from a template, because they are
131      almost identical), for now they are included in obcs_prescribe_read.F for
132      simplicity
133    o pkg/exf:
134      - add a little more diagnostic to exf_interp_read (in analogy to
135        mds_read_field, can be turned off with debugLevel < debugLevA=1)
136      - improve vectorizability of exf_interp for TARGET_NEC_SX, makes code
137        ugly but fast by unrolling short inner loops, inserting a unroll=8
138        directive in routine lagran, and splitting a loop and making do while the
139        outermost loop (the latter requires the intoduction of index arrays)
140    o pkg/obcs: replace obcs_apply_area/heff/hsalt/hsnow with obcs_apply_seaice
141    o pkg/seaice: moved DIFFERENT_MULTIPLE from seaice_model to seaice_dynsolver
142      http://forge.csail.mit.edu/pipermail/mitgcm-devel/2008-January/003173.html
143    o verification/seaice_obcs: updated for restart test and latest options
144    o pkg/seaice: add a new flag SEAICEuseTEM to use a slightly different
145      ice rheology (so-called truncated ellipse, that gets rid of tensile stress);
146      for now this is only available for the C-grid code and also within
147      #ifdef SEAICE_ALLOW_TEM, because this option may slow down the EVP code
148    
149    checkpoint59m
150    o pkg/seaice: use different time constant for melting (SEAICE_gamma_t)
151      and freezing (SEAICE_gamma_t_frz) ice due to mixed layer temperature
152    o gad_som : fix flux output (& diagnostics) to have same units as other  
153      advection scheme fluxes (was previously multiplied by deltaT).  
154    o added verification/seaice_obcs both to test seaice open boundaries
155      and to provide an example matlab scrpt for generating them
156    o added verification/lab_sea/input.salt_plume for testing pkg/salt_plume
157    o pkg/salt_plume: clean up salt_plume_frac.F to
158      remove redundancy in PlumeMethod 1 and 4
159    o pkg/kpp: added saltplume diagnostics
160    o pkg/obcs and pkg/seaice:
161      - do not set uice and vice to zero when OB*icefile are unspecified
162      - OBCS_SEAICE_AVOID_CONVERGENCE is undefined by default
163      - moved seaice tracer obcs after call to seaice_growth
164    o pkg/salt_plume: added various options for salt plume depth
165      criterion and for vertical distribution of the salt
166    
167    checkpoint59l
168    o pkg/ptracers: new version of ptracers pickup:
169      read meta file and write only fields which are needed to restart.
170      ( same logic as main pickup file ; also using pickupStrictlyMatch )
171    o pkg/seaice:
172      - add timescale for melting due to warm mixed layer as a means of
173        setting SEAICE_availHeatFrac more conveniently
174      - add a CPP-flag/runtime parameter check for flooding algorithm
175      - reformulated availHeat in seaice_growth.F to be independent of AREA
176    o change units attribute of EmPmR netcdf variables to kg/m^2/s to reflect recent
177      unit changes
178    o pkg/obcs: added OBCS_SEAICE_AVOID_CONVERGENCE constraint
179    o cg2d.F: add 3 compiler directives that speed up this routine by 30% on a NEC
180      SX vector computer.
181    o pkg/seaice:
182      - removed SEAICE_FFIELDS.h and seaice_get_forcing.F
183        seaice forcing fields can now be read only through pkg/exf
184      - removed some unused halos
185    o no longer write pickup from THE_MODEL_MAIN but always from FORWARD_STEP
186    o pkg/exf: added useRelativeWind EXF_PARAM.h option for subtracting U/VVEL
187      or U/VICE from U/VWIND before computing U/VSTRESS
188    
189    checkpoint59k
190    o pkg/seaice: ICE2WATR=SEAICE_rhoIce/rhoConst for consistency between
191      dynamics and thermodynamics. Set ICE2WATR=0.92 to reproduce older results.
192    o fix un-initialised variable problem (in mom_vecinv & shap_filt):
193      all experiments pass when compile with un-initialised var. checking option.
194    o added pkg/salt_plume
195    o script to test restart (for now, in MITgcm_contrib/jmc_script)
196    o pkg/seaice: new read/write pickup version.
197      read meta file and write only fields which are needed to restart.
198      ( same logic as main pickup file ; also using pickupStrictlyMatch )
199    o pkg/seaice: fix bug in seaice_ocean_stress (call of seaice_calc_strainrates)
200    o lab_sea.hb87: modify the domain & update output.hb87.txt :
201      lat-long grid & no-slip BC in seaice-dynamics produce different sigma12
202      at j=1 & j=Ny+1 : this case is not treated correctly in the restart
203      process. Fixed here by closing the domain at the Northern boundary.
204    o pkg/rw: cleaning-up: call directly new MDSIO S/R MDS_READ/WRITE_FIELD.
205    o pkg/mdsio: add new arguments to MDS_READ/WRITE_FIELD for reading/writing
206      a set of consecutive levels in/from a 3-D array.
207    o pkg/ptracers:
208      use a 2 characters string ioLabel to identify tracer (if more than 99 tracers).
209      to-do: fix pkg/diagnostics when large number of diagnostics are defined.
210    
211    checkpoint59j
212    o in pkgs: dic, obcs, offline, rbcs:
213      standard way to compute coeff. for time interpolation between 2 time reccords
214      which retains full precision (& make results less dependent on compiler).
215      update output of exp: tutorial_cfc_offline & tutorial_global_oce_biogeo.
216    o pkg/cfc: if compiled with exf and seaice, cfc now can use fields from those
217      packages instead of reading ice cover and wind speed separately
218    o split PTRACERS.h in 2 header files: PTRACERS_FIELDS.h & PTRACERS_PARAMS.h
219     (keep a temporary version of PTRACERS.h in verification/OpenAD/code_ad_openad
220      to allow to compile customized code before the update)
221    o cleaning-up:
222      - fix CPP instruction syntax in pkg/obcs
223      - replace (some) call to MDSIO S/R with call to RW interface S/R ; and
224        add #ifdef ALLOW_MDSIO elsewhere (allows to compile without pkg/mdsio)
225      - fix some threads issue in IO parts.
226    o pkg/dic:
227      - add tons of "_d 0" (--> much better testreports !)
228       and then update outputs of tutorial_global_oce_biogeo
229    o pkg/mom_fluxform:
230      add a special version of momentum advection intended to conserve momentum
231      next to a bathymetry step or a coastline edge. (default = off = #undef)
232    o new read/write pickup version:
233      - for now, only implemented for main (mdsio) pickup file.
234      - write out only what is needed to restart; merge pickup_nh , pickup_ph
235        and main pickup together.
236      - read meta file; read only what is needed to restart; stop if a field
237        is missing (if pickupStrictlyMatch=T, = the default) or try to restart
238        if it make sense (even if the restart is not perfect).
239      - if no meta file, assume that pickup to read corresponds exactly to
240        a pickup that would currently be written.
241      - read pickup written in the old format (until checkpoint59i) if it
242        recognizes an old meta file (no field-list).
243      - add a meta file in exp. which starts from a pickup: 2 cases:
244        a) minimal meta file (with just file precision) + pickupStrictlyMatch=F
245         e.g.: global_ocean.90x40x15/input/pickup.0000036000.meta
246        b) a meta file describing the content of the associated pickup file
247         e.g.: tutorial_global_oce_biogeo/input/pickup.0004248000.meta
248    o pkg/mdsio & pkg/rw:
249      - new routine to read a meta file ; new set of routine to read
250        Multiple-fields file (with meta file).
251    o added open boundary conditions capability for seaice
252        HSNOW, HSALT, UICE, and VICE
253    
254    checkpoint59i
255    o adjoint:
256      * fix multiDimAdvection adjoint
257        (partial recomputation problem by TAF for fVerT(:,:,kDown)
258        and comlev1 size definition (maxpass vs. max. number of tracers)
259      * verification/global_ocean.90x45x15 adjoint now tests
260        NLFS and multiDimAdvection using DST3 (=30)
261      * verification/lab_sea now tests multiDimAdvection using DST3 (=30)
262    o pkg/kpp: add "_d 0" to real constant (if missing);
263      update output of exp: natl_box (10.digits); vermix (std, 7.digits)
264      and lab_sea, 3.FW (only 6,4,6 digits match) & AD (8.digits).
265    o prepare for "clever pickup" implementation: add new header file "RESTART.h"
266      for internal parameters related to restart process (formerly from PARAMS.h)
267      and add startAB parameter to argument list of S/R ADAMS_BASHFORTH2.
268    o more standard interface to {PKG}_WRITE_PICKUP with pickup suffix passed
269      as argument. (only atm2d & obcs write_pickup have not yet been updated)
270    o pkg/monitor:
271      - use GLOBAL_SUM_TILE instead of _GLOBAL_SUM
272      - fix mon_stats_rs (statistics over the full domain, even where field is zero)
273      - account for deep Atmosphere factor and density factor (anelastic)
274    o added open boundary conditions capability for seaice HEFF and AREA
275    o pkg/shelfice: add option for convservative form of Hellmer&Olbers (1989)
276      thermodynamics
277      - requires a little reorganization, which affects the testreport results
278        of isomip.htd (only 7 digits of cg2d agree) => update/modify experiment,
279        so that now the conservative form is tested
280      - add a few comments
281    o add missing cvs Header: or Name: in eesupp/*, pkg/* & verification/code*
282    o add a little bit of code to gad_os7mp_adv_?.F to help vectorization
283    o add new diagnostics to seaice: advective, diffusive fluxes (only for
284      multidim-advection, for scheme 2 they are not filled) and transports,
285      thermodynamic growth rates
286    o change units of EmPmR (inside the code, + within coupling interface)
287      from m/s to kg/m2/s (mass flux) but leave input file unchanged.
288      Affects results @ truncation level (cg2d match) and update output of
289       experiments: lab_sea(6), global_ocean.90x40x15(10),
290      global_ocean.cs32x15(11x3,10), natl_box(11), tutorial_global_oce_latlon(11)
291      + adjoint results: global_ocean_ebm(11) and lab_sea (12).
292      Coupled set-up: allow to restart from previous pickups (cpl_oldPickup=T).
293      Next: will retire convertEmP2rUnit (simply using mass2rUnit instead).
294    
295    checkpoint59h
296    o pkg/exf:
297      - improve vectorization by moving if-statement out of loops in
298        exf_mapfields, exf_radiation
299      - exf_bulkformulae.F: introduce 2D fields and vectorize code
300    o pkg/kpp: added the salt plume scheme (ALLOW_SALT_PLUME) to KPP package
301    o testreport:
302      - allow to test for Qnet & SeaIce monitor output; clean-up ALLOW_BULK_OFFLINE
303        monitor & update offline_exf_seaice exp. output.
304      - AD testing: pass/FAIL according to Grad. output accuracy (instead of Cost)
305    o pkg/seaice:
306      - bug fix in the evp solver: boundary conditions were affected be
307        masking of zMax/zMin (changes results)
308      - minor bug fix in boundary conditions in seaice_calc_strainrates
309        (changes results for no_slip)
310      - seaice_lsr.F: make interpolation of eta dependent on boundaries
311      - replace hardcoded lower limit for zeta (zMin) by runtime parameter
312      - add a test to lab_sea, that tests the Hibler and Bryan (1987) ocean
313        stress formulation and no-slip boundary conditions
314    o pkg/ptracers: Temporary fix for PTRACERS_useGMRedi & PTRACERS_useKPP
315      in gad_calc_rhs.F ; add few safety stops in initialisation phase.
316    o pkg/seaice: a first HSALT time stepping equation has been checked in
317    o pkg/seaice: replaced maskW with seaiceMaskU and maskS with seaiceMaskV
318      in seaice_lsr.F; this solves the pkg/seaice-pkg/obcs problem
319      without requiring DO-IF statements
320    o pkg/thsice:
321      use continuous power-law function for partition of energy between lateral
322      melting/freezing and thinning/thickening ; old code using step function
323      still available with #undef THSICE_FRACEN_POWERLAW
324      update output of exp: aim.5l_cs.thSI, global_ocean.cs32x15.icedyn & .thsice
325    o testreport: change AD testing : check against results/output_adm.txt
326      using same scripts as for forward test.
327    
328    checkpoint59g
329    o adjoint testing: in preparation for changing testreport:
330      - output format: cost and grad written on separated lines
331      - ad output results in directory "results" (instead of "results_ad")
332    o pkg/seaice: adding ice salinity HSALT as a prognostic variable
333    o pkg/seaice: changes for using pkg/seaice with pkg/obcs
334  o pkg/ecco: allow user defined cost function contributions  o pkg/ecco: allow user defined cost function contributions
