|
o pkg/cfc: |
| 8 |
|
- change time interpolation for atmospheric CFC-11 (now same as for CFC-12); |
| 9 |
|
update output (CFC-11) of experiment cfc_example and tutorial_cfc_offline. |
| 10 |
|
o pkg/seaice: |
| 11 |
|
- allow to use seaice dynamics without pkg/exf (e.g., using pkg/cheapaml) |
| 12 |
|
o pkg/seaice: add Adams-Bashforth2 time discretization for ice dynamics; |
| 13 |
|
so far only for JFNK-solver, turn on with SEAICEuseAB2 = .TRUE. |
| 14 |
|
- requires an additional time level that is stored in the pickup |
| 15 |
|
- you can start with AB2 from a pickup without this time level with |
| 16 |
|
pickupStrictlyMatch = .false. |
| 17 |

|
checkpoint64h (2013/05/26) |
| 19 |
|
o pkg/cheapaml: |
| 20 |
|
- replace one ()**.5 with SQRT + use temp var "cdu = tau/Du" (coare3_flux); |
| 21 |
|
affect machine truncation (but exp cheapAML_box still pass with 13 digits). |
| 22 |
|
- consistent treatment of uWind,vWind location: assume everywhere in |
| 23 |
|
pkg/cheapaml that they are on C-grid (@ uVel,vVel location) |
| 24 |
|
(Note: was already the case for Tair,Qair advection); |
| 25 |
|
add option (INCONSISTENT_WIND_LOCATION) to recover old results. |
| 26 |
|
- compute diabatic forcing only in the interior (excluding overlap regions) |
| 27 |
|
- fill in array "Qsw" (for short-wave heating); |
| 28 |
|
- add diagnostic for precip ; fill-in diagnostics for cheapAML state vars |
| 29 |
|
before any update (consistent with MITgcm state var diagnostics); |
| 30 |
|
- cheapaml_fields_load.F & cheapaml_init_varia.F : only fill outer edges if |
| 31 |
|
non periodic ; + adjusted for uWind,vWind (C-grid). |
| 32 |
|
o pkg/seaice: |
| 33 |
|
- remove dependence of pkg/seaice versus pkg/exf (file: pkg/pkg_depend) and |
| 34 |
|
add explicitly pkg/exf in experiments that currently use pkg/seaice. |
| 35 |
|
- allows to compile pkg/seaice without pkg/exf. |
| 36 |
|
o tools/OAD_support: |
| 37 |
|
- use a local copy (ourRWCPinBd) to ensure index ourRWCP stays within bounds |
| 38 |
|
of array "ourStepOf" in function rvNextAction (revolve.F90). |
| 39 |
|
o pkg/aim_compon_interf renamed to pkg/atm_compon_interf |
| 40 |
|
- change pkg name (to be used with other atmospheric physics pkg) |
| 41 |
|
but by-pass CVS when making the new pkg so that we keep the CVS history. |
| 42 |
|
o pkg/offline: |
| 43 |
|
- call OFFLINE_FIELDS_LOAD from pkg/offline/offline_init_varia.F |
| 44 |
|
(previously called from pkg/dic_surfforcing_init.F) |
| 45 |
|
o model/src: |
| 46 |
|
- re-order sequence of calls within packages_init_variables.F, using |
| 47 |
|
standard order, except for: |
| 48 |
|
DIAGNOSTICS_INIT_VARIA and OFFLINE_INIT_VARIA (called @ the top), |
| 49 |
|
CTRL_MAP_INI and OBCS_INIT_VARIABLES (called @ the bottom) |
| 50 |
|
o new pkg: atm_phys |
| 51 |
|
- add entry point and source code (previously in contrib |
| 52 |
|
verification_other/atm_gray/code_gray/) for new pkg "atm_phys" |
| 53 |
|
(atmospheric physics pkg from P. O'Gorman and T. Schneider, JCl, 2008). |
| 54 |
|
- re-order sequence of calls within packages_readparms.F, |
| 55 |
|
packages_init_fixed.F and packages_write_pickup.F |
| 56 |
|
(but skip packages_init_variables.F because of TAF issues). |
| 57 |
|
- update contrib/*/atm_gray/ experiment. |
| 58 |
|
o pkg/seaice (ITD code): |
| 59 |
|
- simplify and fix the writing of pickup-files for ITD case |
| 60 |
|
o pkg/seaice (ITD code): |
| 61 |
|
- introduce floe size dependent lateral melt for ITD case; |
| 62 |
|
- cleaning (avoid division by zero, change to f77 syntax, remove tabs) |
| 63 |
|
- update seaice_itd experiment main output. |
| 64 |
|
o pkg/thsice: |
| 65 |
|
- remove snowPrc from common block THSICE_FLUX, in THSICE_VARS.h and |
| 66 |
|
declared it locally (without bi,bj) in thsice_main.F & aim_do_physics.F; |
| 67 |
|
changed accordingly pkg/atm2d. |
| 68 |
|
|
| 69 |
|
checkpoint64g (2013/05/01) |
| 70 |
|
o pkg/exf ALLOW_RUNOFTEMP |
| 71 |
|
- if defined, river and glacier runoff temperature can be read-in from |
| 72 |
|
runoftempfile; runoftempfile needs to have same format as runofffile |
| 73 |
|
o pkg/thsice (& pkg/bulk_force): |
| 74 |
|
- In case Energy-Reference-Level (ERL) is used (temp_EvPrRn=0), account |
| 75 |
|
for energy content of Precip + RunOff & Evap (like with pkg/exf). |
| 76 |
|
- change computation domain to always be the interior (without overlap). |
| 77 |
|
- fix bug (wrong overlap) when using EXF and stressReduction > 0. |
| 78 |
|
o verification/tutorial_global_oce_biogeo: |
| 79 |
|
- add preliminary OpenAD setup (still has problems) |
| 80 |
|
o pkg/seaice: |
| 81 |
|
- turn some parameters for choosing the convergence criterion of |
| 82 |
|
the inexact Newton method (JFNK) into runtime parameters for convenience |
| 83 |
|
- clean up seaice_calc_viscosities.F: remove/retire two options for |
| 84 |
|
SEAICetaZmethod (1,2), introduce area weighting for method 3; this changes |
| 85 |
|
the results of lab_sea/input because a division has been replaced by |
| 86 |
|
a multiplication with the reciprocal (sumNorm) |
| 87 |
|
- modify offline_exf_seaice/input.dyn_jfnk/data.seaice to improve |
| 88 |
|
convergence of solver (changes results, of course), and to test some |
| 89 |
|
new features |
| 90 |
|
o model/src: |
| 91 |
|
- remove unused (since Aug 2006) S/R SET_WRITE_GLOBAL_PICKUP and its call. |
| 92 |
|
- remove unused forcing field "dQdT" and associated parameter "dQdTFile". |
| 93 |
|
- move forcing adjustment (balancing surface forcing) in specific S/R |
| 94 |
|
where might also be applied exchanges (if needed) to forcing arrays. |
| 95 |
|
o pkg/shelfice: |
| 96 |
|
- allow to specify the Ice-Shelf mass per unit area (instead of |
| 97 |
|
shelficeLoadAnomaly) and do the conversion from one to the other |
| 98 |
|
- move loading from file of shelficeLoadAnomaly from SHELFICE_INIT_VARIA |
| 99 |
|
to SHELFICE_INIT_FIXED: (a) avoid some TAF recompution issues and |
| 100 |
|
(b) will be loaded in time (before calling INI_PRESSURE) in case it is |
| 101 |
|
needed in phi0surf for initial pressure calculation when useDynP_inEos_Zc |
| 102 |
|
- update isomip experiment forward output (get machine truncation error |
| 103 |
|
from conversion shelficeLoadAnomaly -> shelficeMass -> shelficeLoadAnomaly) |
| 104 |
|
o verification/offline_exf_seaice: |
| 105 |
|
revise data.seaice in input.thermo and input_ad and update results accordingly |
| 106 |
|
HO = 0.2, SEAICE_areaLossFormula = 2, |
| 107 |
|
SEAICE_growMeltByConv = .TRUE., |
| 108 |
|
SEAICE_doOpenWaterMelt = .TRUE., |
| 109 |
|
Improve consistency with input.thsice and fix the spurious 500m ice corners |
| 110 |
|
o verification/global_ocean.cs32x15: |
| 111 |
|
- set Energy Reference Level to liq. water @ 0 degC: temp_EvPrRn=0., |
| 112 |
|
in icedyn (thsice+seaice-dyn) test and update output. |
| 113 |
|
o verification/offline_exf_seaice: |
| 114 |
|
- adjust list of tested variables (with testreport) and update |
| 115 |
|
standard test output with better slection of monitored fields. |
| 116 |
|
o pkg/cd_code: |
| 117 |
|
- swtich off Adams-Bashforth on the 1rst iteration. Update output of |
| 118 |
|
experiment lab_sea.hb87 |
| 119 |
|
o tools/genmake2: |
| 120 |
|
- change default makedepend from the system default to tools/xmakedepend: |
| 121 |
|
When no makedepend is specified, select tools/xmakedepend it the test pass, |
| 122 |
|
otherwise select the system default (if exist and pass the test) or |
| 123 |
|
try to build cyrus-makedepend ; stop if none of the 3 works. |
| 124 |
|
o pkg/exf & pkg/thsice: |
| 125 |
|
- In case Energy-Reference-Level (ERL) is used (temp_EvPrRn=0), account |
| 126 |
|
for energy content of Precip + RunOff & Evap. Assumes: |
| 127 |
|
1) Rain has same temp as Air. |
| 128 |
|
2) Snow has no heat capacity (consistent with seaice & thsice pkgs) |
| 129 |
|
3) Run-Off comes at the temp of surface water (with same Cp) |
| 130 |
|
4) Evap over ocean is released to the Atmos @ surf-temp (=SST); should be |
| 131 |
|
put directly into Latent Heat flux & should use water-vapor heat capacity. |
| 132 |
|
5) Evap over snow/seaice (pkg/thsice) assumes constant Lf+Lv (consistent |
| 133 |
|
with snow having no Cp) => water vapor is released to Atmos @ 0^oC (=ERL). |
| 134 |
|
o pkg/seaice: simplify the use of CPP flags in JFNK-related files |
| 135 |
|
(compile when SEAICE_ALLOW_JFNK is defined) |
| 136 |
|
o pkg/thsice: |
| 137 |
|
- fix oceanic flux diagnostics & timeave (left from new sequence of calls |
| 138 |
|
implementation): move THSICE_AVE call after the advection (called directly |
| 139 |
|
from thsice_do_advect.F). |
| 140 |
|
o verification/global_ocean.90x40x15 and OpenAD: |
| 141 |
|
New experiment for OpenAD is identical to the one in input_ad except that |
| 142 |
|
multiDimAdvection=.FALSE., |
| 143 |
|
There is still an issue with this. |
| 144 |
|
o pkg/thsice: |
| 145 |
|
- account for ice velocity (ocean relative velocity) in turbulent heat flux |
| 146 |
|
at the base of the ice; update output of global_ocean.cs32x15 (icedyn) |
| 147 |
|
and offline_exf_seaice (main test). |
| 148 |
|
|
| 149 |
|
checkpoint64f (2013/03/31) |
| 150 |
|
o verification/OpenAD: |
| 151 |
|
- new (smaller, without OAD_DEBUG) output_oadm.txt generated using gfortran. |
| 152 |
|
o verification/isomip, pkg/shelfice and OpenAD: |
| 153 |
|
- add OpenAD setup to this exp and make shelfice package work with OpenAD |
| 154 |
|
o verification/tutorial_global_oce_biogeo: |
| 155 |
|
- update AD and TLM output after turning off ALLOW_FE (in DIC_OPTIONS.h) |
| 156 |
|
o verification/offline_exf_seaice: |
| 157 |
|
- replace adjoint experiment (now similar to fwd input.thermo/ setup). |
| 158 |
|
o verification/tutorial_tracer_adjsens, pkg/ptracers and OpenAD: |
| 159 |
|
- add OpenAD setup to this exp and make ptracers package work with OpenAD |
| 160 |
|
o pkg/seaice/seaice_evp.F: |
| 161 |
|
mask the asymmetric contribution of the ice-ocean stress (when |
| 162 |
|
the turningAngle is non-zero) over open water to avoid stripes |
| 163 |
|
in the EVP-solutions after many EVP-substeps. This does not change |
| 164 |
|
the verification experiment (because turningAngle=0 in that experiment), |
| 165 |
|
but will affect other EVP solutions with turningAngle.ne.0 |
| 166 |
|
o verification, AD & TLM output: |
| 167 |
|
- new TAF version 2.3.10 (previously 2.3.8) add more parenthesis in multiple |
| 168 |
|
additions and multiplications which affect results at machine truncation |
| 169 |
|
level. Update few AD output (1D_ocean_ice_column, bottom_ctrl_5x5, |
| 170 |
|
lab_sea.noseaicedyn & offline_exf_seaice) and TLM output |
| 171 |
|
(1D_ocean_ice_column & tutorial_tracer_adjsens.som81) which had only 12 |
| 172 |
|
digits of matching. |
| 173 |
|
o pkg/seaice: |
| 174 |
|
modify lsr-algorithm so that it vectorizes AND converges by using a |
| 175 |
|
"zebra" method: split vector loop into two with step size 2; this |
| 176 |
|
solves a general convergence problem for the JFNK solver on a vector |
| 177 |
|
computer. It has the potential to even improve convergence for |
| 178 |
|
non-vector machines, but it does change the results so it is turned |
| 179 |
|
off by default. To turn on define CPP-flags SEAICE_VECTORIZE_LSR and |
| 180 |
|
SEAICE_VECTORIZE_LSR_ZEBRA in SEAICE_OPTIONS.h |
| 181 |
|
|
| 182 |
|
checkpoint64e (2013/03/05) |
| 183 |
|
o pkg/ecco and several verification experiments: |
| 184 |
|
Remove special versions of the_model_main.F, the_main_loop.F, forward_step.F |
| 185 |
|
from ecco package, and revert to unified routine in model/src/ |
| 186 |
|
Adjust verification experiments accordingly, especially gloal_oce_llc90 |
| 187 |
|
Should conclude long-standing work by Gael to reconsile the_main_loop with |
| 188 |
|
ECCO and will enable OpenAD's revolve loop in ECCO setup. |
| 189 |
|
o pkg/generic_advdiff: |
| 190 |
|
- implement compressible flow method for multi-dim advection (similar to |
| 191 |
|
gad_som_advect.F); add new option "GAD_MULTIDIM_COMPRESSIBLE" (since |
| 192 |
|
TAF generates many recomputations) to use it; no yet coded with implicit |
| 193 |
|
vertical advection. |
| 194 |
|
- change experiment advect_cs (new output) and advect_xy (same output) |
| 195 |
|
to test compressible flow multi-dim advection. |
| 196 |
|
o pkg/generic_advdiff: |
| 197 |
|
- fix SOM advection for unusual cases (linear Free-Surf in r*, other |
| 198 |
|
cases where linear Free-Surf is not @ k=1, e.g., useShelfIce) |
| 199 |
|
o pkg/seaice: |
| 200 |
|
- fix bug in the no-slip implementation in seaice_calc_strainrates.F, this |
| 201 |
|
bug affects two verification experiments (lab_sea and lab_sea.hb87), |
| 202 |
|
recover old (wrong) results by setting noSlipFac = 2. in |
| 203 |
|
seaice_calc_strainrates.F; |
| 204 |
|
- add another averaging method for etaZ (etaZmethod=3), a mix of 2 and 0 |
| 205 |
|
- add runtime parameter SEAICE_JFNKepsilon for that finite difference |
| 206 |
|
gradient in the Jacobian times vector operation (s/r seaice_jacvec) |
| 207 |
|
- fix line search in seaice_jfnk.F (s/r seaice_jfnk_update) |
| 208 |
|
o pkg/seaice: reorganize seaice_lsr.F to be able to reuse more code: |
| 209 |
|
- new subroutines seaice_lsr_tridiagu/v |
| 210 |
|
- introduce loop bounds i/jmin/max to be able to use a restricted |
| 211 |
|
additive Schwarz method, but not used for now. |
| 212 |
|
- rename SEAICE_CALC_LSR_COEFFS into SEAICE_LSR_CALC_COEFFS |
| 213 |
|
- use new subroutines seaice_lsr_tridiagu/v in s/r seaice_preconditioner |
| 214 |
|
o OpenAD support |
| 215 |
|
Reorganize S/R call for overall time-stepping loop to facilitate |
| 216 |
|
OpenAD revolve loop replacement |
| 217 |
|
(new S/R main_do_loop.F) |
| 218 |
|
o model/src: |
| 219 |
|
- add 3-D array 3rd dimension to argument list of S/R ADAMS_BASHFORTH2/3; |
| 220 |
|
- pkg/cheapaml: remove local S/R ADAMS2d and use instead standard S/R |
| 221 |
|
ADAMS_BASHFORTH2. |
| 222 |
|
o pkg/cheapaml: |
| 223 |
|
- add new parameter (default=F, same as before) to disable full domain |
| 224 |
|
(including land) periodicity in X & Y dir. |
| 225 |
|
- new S/R CHEAPAML_COPY_EDGES to copy relaxation field into edges of |
| 226 |
|
prognostics field ; merge the 2 S/R cycle_2d_tracer and timestep_2d_tracer |
| 227 |
|
into single S/R CHEAPAML_TIMESTEP. |
| 228 |
|
|
| 229 |
|
checkpoint64d (2013/02/17) |
| 230 |
|
o pkg/monitor (angular momentum): |
| 231 |
|
- do not add Eta contribution to the total AM if using rigid-lid; |
| 232 |
|
- correct for Adams-Bashforth in zonal-wind part (instead of in AM_eta). |
| 233 |
|
- horizontal discretisation: compute Zonal wind contribution separately for |
| 234 |
|
each component (instead of from cell centered averaged) and use the 4 |
| 235 |
|
grid-cell corner averaged value of Omega*(R*cos_Phi)^2 in AM_eta part. |
| 236 |
|
- Check that AM is conserved with linear dynamics (momAdvection=F and linear |
| 237 |
|
FreeSurf) if using vectorInvariant momentum. |
| 238 |
|
o model/src (horizontal grid): |
| 239 |
|
- move initialisation of all horizontal grid arrays to null value |
| 240 |
|
from specific horizontal grid S/R to main S/R INI_GRID; |
| 241 |
|
- add 2 new arrays to project model C-grid velocity on to zonal direction |
| 242 |
|
(similar to AngleCosC & -AngleSinC but at U and V point location) and |
| 243 |
|
compute them in S/R CALC_GRID_ANGLES. |
| 244 |
|
o pkg/seaice: replace a hard coded parameter by a runtime parameter |
| 245 |
|
SEAICE_JFNK_tolIter |
| 246 |
|
o pkg/seaice: introduce a restricted additive Schwarz (RAS) method in |
| 247 |
|
preconditioner for JFNK (run LSR into the overlaps as far as possible, |
| 248 |
|
i.e OLx/y-2, but overwrite the solution in the overlaps) |
| 249 |
|
- extend loop range in seaice_calc_viscosity |
| 250 |
|
- add new parameters SEAICE_OLx/y (default = OLx/y-2) |
| 251 |
|
- add flexible loop ranges to seaice_preconditioner, seaice_calc_lsr_coeffs |
| 252 |
|
- slightly modify loops in tridiagonal solver lsr-preconditioner |
| 253 |
|
- by default remove the extra exchange in seaice_preconditioner with a |
| 254 |
|
replacement of an undocumented CPP flag by SEAICE_PRECOND_EXTRA_EXCHANGE |
| 255 |
|
- modify offline_exf_seaice so that old results without RAS are reproduced |
| 256 |
|
for output.dyn_jfnk.txt |
| 257 |
|
in seaice_fgmres.F (unrelated to RAS) |
| 258 |
|
- add a cpp-flag option for a re-ordered mapping (potentially more |
| 259 |
|
efficient), but because this changes the results, turn it off by |
| 260 |
|
default |
| 261 |
|
- replace the save statement by local common blocks |
| 262 |
|
o utils/matlab: |
| 263 |
|
- fix tile-offset in rdmnc.m when output was produced using EXCH2. |
| 264 |
|
- update cs_grid/bk_line scripts to use load_grid.m (in utils/matlab) |
| 265 |
|
instead of local script "load_cs.m". |
| 266 |
|
o pkg/seaice: |
| 267 |
|
- fix a serious bug in seaice_fgmres.F, s/r seaice_scalprod, connected |
| 268 |
|
to the scalarProductMetric and the unrolling. By chance this does not |
| 269 |
|
change the verification experiment, because of the particular domain |
| 270 |
|
decomposition |
| 271 |
o pkg/diagnostics: |
o pkg/diagnostics: |
| 272 |
- change default missing_value from UNSET_RL to -999. |
