7 |
|
o move balancing of fluxes before the call of external_forcing_surf |
8 |
|
o seaice: |
9 |
|
- correct units of turning angles (now they are really in degrees) |
10 |
|
- move computation of GWATX/Y out of main routine into dynsolver |
11 |
|
- initialize GWATX/Y in seaice_init |
12 |
|
o Apply mask on Fresh-Water flux (needed for SSH forcing). |
13 |
|
update output.txt of exp. global_ocean_ebm & cpl_aim+ocn (affects cg2d residual) |
14 |
|
o seaice: add runtime flags for turning angles (default to zero) |
15 |
|
o Adding runtime parameter to exf/, ctrl/, to remove on-the-fly global mean |
16 |
|
and trend from exf forcing and ctrl control adjustments |
17 |
|
o fix variable aliasing in gad_calc_rhs that cannot be handled by TAF |
18 |
|
(since checkpoint57x_post) |
19 |
|
o change the default rotation period to 86164.s = the Earth rotation |
20 |
|
o 1rst implementation of Implicit IGW using the 3-D solver (use3Dsolver=T) |
21 |
|
and based on a reference stratification. Tested within hs94.cs-32x32x5. |
22 |
|
o seaice advection: add code for choosing between the default (2nd order |
23 |
|
central differences) and multiDim advection schemes provided by |
24 |
|
pkg/generic_advdiff |
25 |
|
o seaice: |
26 |
|
- removed all references to SEAICE_GRID.h fields from |
27 |
|
dynsolver, advect, diffus, lsr, without changing the results of lab_sea |
28 |
|
(cubed-sphere configuration will change a little) |
29 |
|
- grid computations in seaice_init are obsolete now. |
30 |
|
- cleaned up code a little so that is easier to read (hopefully). |
31 |
|
- added new (better?) discretizations of default advection and diffusion |
32 |
|
(turn on with SEAICEuseFluxForm) |
33 |
|
- replace 1 in 3d global fields by kSurface in growth.F |
34 |
|
|
35 |
|
checkpoint58a_post |
36 |
|
o seaice: |
37 |
|
- bug fix in advect.F |
38 |
|
o shelfice: |
39 |
|
- separate shelfice load anomaly from pload (breaks with time |
40 |
|
dependent forcing), => introduce constant field shelficeLoadAnomaly. |
41 |
|
Its default is 0., but it may be computed more cleverly from (unknown) |
42 |
|
t- and s-profiles (tRef, sRef) and actual EOS. For now this has to be |
43 |
|
done offline. A good approximation of the pressure load anomaly is |
44 |
|
necessary to avoid large initial adjustment processes underneath |
45 |
|
deep-reaching shelfice. |
46 |
|
- small fix in ISOMIP shelfice_thermodynamics |
47 |
|
- add more sophisticated thermodynamics of Hellmer (1989), this is |
48 |
|
now the default |
49 |
|
- give a few constants more intuitive names |
50 |
|
o add code to balance EmPmP and Qnet at the end of do_ocean_physics. Useful |
51 |
|
if bulk formulae are used in long integration (especially EmPmR). Turn |
52 |
|
on with balanceEmPmR = .true. or balanceQnet = .true. in data, PARM01 |
53 |
|
if balancePrintMean, the imbalance that is substracted is printed to |
54 |
|
STDOUT. |
55 |
|
o fix bug (typo) in obcs_apply_eta.F |
56 |
|
o add a new package shelfice which enables us to model the circulation |
57 |
|
underneath shelf-ice with draughts of hundreds of meters. |
58 |
|
- works |
59 |
|
- to do: + include improved thermodynamics |
60 |
|
+ check whether kSurfC (from model/inc/SURFACE.h) can be used |
61 |
|
instead of new field kTopC |
62 |
|
+ can we use topoFile, Ro_surf and existing code in ini_depth.F |
63 |
|
instead of new field R_shelfIce and new code in ini_depth.F |
64 |
|
and ini_mask_etc.F? |
65 |
|
+ adjust vertical mixing schemes? |
66 |
|
o seaice pkg: |
67 |
|
- add a cpp-flag to include a simple formula for a salinity dependent |
68 |
|
freezing point of sea water at the surface |
69 |
|
- change the contents of SEAICE_TEST_ICE_STRESS_1 so that zonal and |
70 |
|
meridional stresses are now different (and hopefully correct) |
71 |
|
o AIM pkg: change threshold on large-scale condensation to conserve Heat. |
72 |
|
update results of aim.5l_LatLon test ; fix title & units of AIM diagnostics |
73 |
|
and change 3 diagnostics names (OSR,OSRCLR,KM -> TSR,TSRCLR,DRAG) |
74 |
|
o pkg/diagnostics: add options and parameters for regional-statistics |
75 |
|
diagnostics ; define regions by reading a region-mask from a file |
76 |
|
(might add other options later) |
77 |
|
o pkg/bulk_force: |
78 |
|
- add option and parameters to use AIM surface-flux formulae. |
79 |
|
- Change loading part: S/R BULKF_FIELDS_LOAD only take care of bulkf_fields ; |
80 |
|
others forcing fields (defined in PARM05, parameter file "data") are loaded |
81 |
|
from S/R EXTERNAL_FIELDS_LOAD, as usually (with useBulkforce = T or F). |
82 |
|
- initialise all bulkf_fields in bulkf_init.F ; do in-lining of exf_bulkcdn.F |
83 |
|
- use the right EXCH call for uwind,vwind (to work on CS-grid). |
84 |
|
- re-arrange header files (move parameters from BULKF.h to BULKF_PARAMS.h) |
85 |
|
and parameters (note: calcWindStress replaces .NOT.readwindstress). |
86 |
|
- cleaner interface with pkg/thSIce (new S/R THSICE_GET_PRECIP). |
87 |
|
|
88 |
|
checkpoint58 |
89 |
|
o add "--embed-source" option to genmake2 which, when the supporting |
90 |
|
tools can be compiled (as determined by genmake2) will turn on the |
91 |
|
embed_files package which then embeds the entire MITgcm source code |
92 |
|
(*.[fFhc] + Makefile) used for the build within the executable |
93 |
|
- requested by CNH but off by default |
94 |
|
- adds a paltry <9MB to the mitgcmuv executable in most cases |
95 |
|
- only writes the output when useEMBEDSRC in eedata is true |
96 |
|
o clean up 3-dim. relaxation codes: |
97 |
|
* Fix I/O inconsistency in pkg/rbcs: replace precFloat32 by readBinaryPrec |
98 |
|
* Remove 3-dim. relaxation code from pkg/exf (now use only pkg/rbcs) |
99 |
|
* Thanks to Tom Haine for testing! |
100 |
|
|
101 |
|
checkpoint57z_post |
102 |
|
o make CG3D solver compatible with Free-surface at k > 1 (p-coordinate): |
103 |
|
affects output (@ truncation level) of exp. plume_on_slope ; updated. |
104 |
|
o fix the pickup behavior for obcs in combination with ptracers |
105 |
|
o fix a bug in ptracers_external_fields_load |
106 |
|
o no AB-2 at the first iteration for Gw (consistent with Gu,Gv,Gt,Gs ...) |
107 |
|
affects results of NH experiments (but all our NH tests have Gw[it=1]==0 !!) |
108 |
|
o transfered surface NH pressure to eta field (if exactConserv). |
109 |
|
o gmredi: fix bugs in slope tapering ldd97 (depthZ had the wrong sign) |
110 |
|
and update lab_sea output.txt file. |
111 |
|
o completing 3-dim. relaxation code: additional term |
112 |
|
1/tau*( theta(i,j,k) - thetaStar(i,j,k) ) |
113 |
|
in S/R EXTERNAL_FORCING_T (file external_forcing.F) |
114 |
|
* At compile time, in "EXF_OPTIONS.h" set |
115 |
|
#define ALLOW_CLIMTEMP_RELAXATION |
116 |
|
#define ALLOW_CLIMSALT_RELAXATION |
117 |
|
* At runtime in "data", under &PARM03 set (e.g., units in seconds) |
118 |
|
tauThetaClimRelax3Dim = 15552000.0, |
119 |
|
tauSaltClimRelax3Dim = 15552000.0, |
120 |
|
* 3 cases: |
121 |
|
1) Use a constant-in-time 3-dim. field |
122 |
|
2) Provide 12 3-dim. fields corresponding to Jan., ... , Dec. |
123 |
|
3) Real-time relax. to time-evolving prescribed field |
124 |
|
o Adding Laplacian-type smoothness constraint on |
125 |
|
initial and boundary (forcing) controls (ic, bc) |
126 |
|
* enable at compile-time via |
127 |
|
ALLOW_SMOOTH_IC_COST_CONTRIBUTION, ALLOW_SMOOTH_BC_COST_CONTRIBUTION |
128 |
|
* enable at run-time via mult_smooth_ic = 1, mult_smooth_bc = 1 |
129 |
|
* Absolute scale somewhat unclear so far |
130 |
|
* no area weighting was included since no other cost term does so far |
131 |
|
|
132 |
|
checkpoint57y_post |
133 |
|
First step for a NLFS adjoint |
134 |
|
o initially suppress rStar (new flag DISABLE_RSTAR_CODE) |
135 |
|
o new init. routines for calc_r_star, calc_surf_dr |
136 |
|
o still need to deal with ini_masks_etc |
137 |
|
o testreport seemed happy |
138 |
|
checkpoint57y_pre |
139 |
|
|
140 |
|
o obcs: always reset wVel & eta (to zero or prescribe it) at the OBs. |
141 |
|
o add new package rbcs (for relaxing ptracers at boundaries/depth/surface etc) |
142 |
|
o add new offset feature to offline pkg (plus minor cleanup) |
143 |
|
o cfc fixes for final year of integration |
144 |
|
o clean up GCHEM_OPTIONS.h/DIC_OPTIONS.h (all options should |
145 |
|
be in GCHEM_OPTIONS). |
146 |
|
|
147 |
|
checkpoint57x_post |
148 |
|
o fix testreport Pb in multiple test experiment. |
149 |
|
o cleanup our namelist syntax in verification: |
150 |
|
- make it more F95 standards compliant (some work still needed) |
151 |
|
- allows the vast majority of our tests to work with gfortran |
152 |
|
o Non-Hydrostatic: |
153 |
|
- put all NH variables (formerly in DYNVARS.h & GW.h) in NH_VARS.h |
154 |
|
- fix exchange calls for CS-grid using the new EXCH_S3D_RL. |
155 |
|
o Allow to apply AB on T,S rather than on AB(gT,gS): |
156 |
|
- implemented within #ifdef ALLOW_ADAMSBASHFORTH_3 |
157 |
|
- use the same arrays (gtNm,gsNm) to hold tracer field at previous |
158 |
|
time-steps (if AB(T,S)) and tendencies (if AB(gT,gS)). |
159 |
|
- need a "clever" read_pickup to restart from the other AB formulation |
160 |
|
o move local commom bloc /GlobalLo/ (used for singleCpuIO) in EESUPPORT.h |
161 |
|
o remove some unused variables (reduces number of compiler warnings) |
162 |
|
o adjoint |
163 |
|
* Disable useVariableViscosity for adjoint for time being |
164 |
|
(there are a number of extensive recomputations) |
165 |
|
* Initialize certain variables needed for adjoint |
166 |
|
|
167 |
|
checkpoint57w_post |
168 |
|
o pkg/mdsio: use MAX_LEN_FNAM (instead of hard coded 80) for file-names |
169 |
|
fix the singleCpuIO RS version of MDSWRITEFIELD |
170 |
|
and add a WARNING if using globalFiles=T with multi-processors. |
171 |
|
o write grid-file(s) in only one format (MDS or MNC): default=MNC (if |
172 |
|
using MNC); can force MDS output by setting writegrid_mnc=F in data.mnc |
173 |
|
o tracer advection scheme: |
174 |
|
add DST-2 (=Lax-Wendroff) & 1rst order upwind schemes (the way to get |
175 |
|
those 2 schemes before, changing GAD_FLUX_LIMITER.h + to recompile, |
176 |
|
was not very convenient). |
177 |
|
add implicit version for DST-3 & DST3_Flux_Limit vertical advection; |
178 |
|
(further tests needed for the implicit DST & Flux-Limiter schemes). |
179 |
|
o PTRACERS: added namelist parameter PTRACERS_ref in analogy to tRef |
180 |
|
and sRef for convenience, handy, when you want to initialize |
181 |
|
ptracers in a large domain with a constant non-zero value. Also, |
182 |
|
untangle ptracers_init.F a little. |
183 |
|
|
184 |
|
checkpoint57v_post |
185 |
|
o change dome exp. to use variable viscosity in side-drag terms. |
186 |
|
o remove all the files from the cfc_offline test since they are now |
187 |
|
incorporated into tutorial_cfc_offline which has been producing |
188 |
|
identical results for a few days of testing |
189 |
|
o add new parameter: sideDragFactor to enable half-slip-side BC |
190 |
|
and change side-drag S/R to use viscosity from mom_calc_visc |
191 |
|
(can switch back by setting sideDragFactor=0.); affects results at |
192 |
|
truncation level; regenerate output for exp.: global_ocean.cs32x10(x3), |
193 |
|
global_ocean_ebm, global_ocean_pressure, matrix_example & MLAdjust(x5). |
194 |
|
o vorticity & strain are now computed without masking, to account for |
195 |
|
no-slip-side BC in variable viscosity calculation ; mask is applied |
196 |
|
anyway later on, before computing advection/coriolis terms. |
197 |
|
o modify exp4 to test new obcs support for reading from external files |
198 |
|
and for passive tracers |
199 |
|
o fix behavior of ptracers_monitor when monitor output is written to a |
200 |
|
netcdf-file; still not independent of monitor.F (writes in the same |
201 |
|
file). |
202 |
|
o change default value of tRef (put a uniform, meaningful value for ocean |
203 |
|
& atmos) and initialize sRef (was missing, as Martin mentioned). |
204 |
|
o Redefine viscC?Leith*. Change the coefficients of Leith viscosity |
205 |
|
to be proportional to enstrophy dissipation length. Thus, |
206 |
|
viscC?leith?_new=pi*(viscC?leith?_old)^(1/3) |
207 |
|
This is now consistent with Smagorinsky and with the manual. |
208 |
|
|
209 |
|
checkpoint57u_post |
210 |
|
o OBCS and PTRACERS: add open boundary support for passive tracers |
211 |
|
- either use homogenous (pseudo) v.Neumann conditions or prescribe |
212 |
|
OB-values from file; this is not different from the way theta and salinity |
213 |
|
are treated |
214 |
|
- however, Orlanski-radiation conditions are not supported, and the model |
215 |
|
will stop if you use pTracers and Orlanski at the same time. |
216 |
|
- beefed up the rountine obcs_external_fields_load: now only those open |
217 |
|
boundary values are overwritten with values from files for which there |
218 |
|
are really files, otherwise the OB-fields remain untouched. This makes |
219 |
|
it possible to use different OBs at different ends of the domain (as |
220 |
|
with EXF) |
221 |
|
o reduce number of exch calls in shap_filt (s2). |
222 |
|
o CS-grid: fix divergence contribution to Leith viscosity. Affects (@ |
223 |
|
truncation level) 4/5 MLAdjust test results (11&12 digits match). |
224 |
|
|
225 |
|
checkpoint57t_post |
226 |
|
o test biharmonic viscosity + no-slip with exp: global_ocean.cs32x15.viscA4 |
227 |
|
o finish adding brackets (coriolis S/R, vecinv) in multi-terms sum to get |
228 |
|
same truncation, independent of the face number: affects affects several |
229 |
|
test. exp.: Update global_ocean.cs32x15 (+.thsice) & MLAdjust (all 5). |
230 |
|
o fix bug in mom_v_sidedrag (biharmonic viscosity was counted 2 times); |
231 |
|
note that biharmonic viscosity + no-slip was not tested in any experiment. |
232 |
|
o fix bug in non-linear free-surf side-drag ; generate new output for |
233 |
|
global_ocean.cs32x15(+.thsice) & global_ocean_pressure. |
234 |
|
o make mnc honor the writeBinaryPrec flag for most kinds of output |
235 |
|
o eesupp: split EEPARAMS into EESIZE/EEPARAMS and add a vector global sum |
236 |
|
o minor change in averaging W (mom_vi_?_vertshear.F) that affects truncation |
237 |
|
error; update output from global_ocean.cs32x15(+.thsice) & MLAdjust (all 5). |
238 |
|
o add brackets in multi-terms sum to get same truncation, independent of |
239 |
|
the face number (manage to get exactly same value of gU,gV at the cs-edge) |
240 |
|
affects several test. exp. Update global_ocean.cs32x15 (+.thsice). |
241 |
|
o Clean, new version of mom_calc_visc. Adds a new feature, viscAhRemax |
242 |
|
and viscA4Remax, which allow one to limit the minimum viscosity by specifying |
243 |
|
a maximum grid-scale Reynolds number. Also, changes all length calculations |
244 |
|
in the case of grid anisotropy to geometric mean of dx**2 and dy**2. |
245 |
|
Suggested values of viscosity parameters found in mom_calc_visc. |
246 |
|
Many new viscosity diagnostics available. |
247 |
|
|
248 |
|
checkpoint57s_post |
249 |
|
o Add clearing-house for viscosity calculations, mom_calc_visc and |
250 |
|
correct numerous bugs in LeithD and Smagorinsky discretizations. |
251 |
|
mom_calc_visc now allows for Smagorinsky, Leith and LeithD to be |
252 |
|
used simultaneously, and to be used in mom_vecinv and mom_fluxform. |
253 |
|
Mom_vecinv can be used with standard viscous calculation (mom_vi_hdissip.F) |
254 |
|
and with Strain-Tension viscous term calculation (mom_hdissip.F). |
255 |
|
The Strain-Tension form is now called with useStrainTensonVisc=.true. |
256 |
|
ViscAhStrain and viscAhTension are now retired. |
257 |
|
o diagnostics "VISCAHD" & "VISCA4D" replace "VISCAH" & "VISCA4". |
258 |
|
o In response to JMC's bug report, genmake2 now ignores any soft-links |
259 |
|
that it finds in the *current* directory when searching for files. |
260 |
|
Soft-links found in any other source directories will still work as |
261 |
|
they did before. |
262 |
|
o add HAVE_SETRLSTK define and useSETRLSTK flag (eedata) which calls |
263 |
|
a C routine to unlimit the stack size |
264 |
|
o mnc-ify pkg/aim snapshot vars |
265 |
|
o mnc-ify pkg/land as requested by Daniel |
266 |
|
o various changes to mnc including: |
267 |
|
- all files use the new "BASENAME[[.ITER].{t|f}NUM].nc" format |
268 |
|
- output can now be grouped so that all files within a group |
269 |
|
change the ITER portion of their names in lock-step together |
270 |
|
- can now read ("global") PER-FACE (in addition to PER-TILE) files |
271 |
|
and works with both EXCH1 and EXCH2 (but needs more testing) |
272 |
|
- writing works for all verification test cases w/ g77 on Linux |
273 |
|
|
274 |
|
checkpoint57r_post |
275 |
|
o make MNC variable initialization happen earlier |
276 |
|
o add diagnostics for (almost) each term of the momentum Eq. |
277 |
o remove SST,SSS,UVEL_k2,VVEL_k2 diagnostics. |
o remove SST,SSS,UVEL_k2,VVEL_k2 diagnostics. |
278 |
o move pkg timeave out of pkg-groups "oceanic" & "atmospheric" (pkg/pkg_groups) |
o move pkg timeave out of pkg-groups "oceanic" & "atmospheric" (pkg/pkg_groups) |
279 |
o remove MINIMAL_TAVE_OUTPUT option ; |
o remove MINIMAL_TAVE_OUTPUT option ; |
