o pkg/seaice: fix a bug computing areaS in seaice_calc_lhs/rhs (J-J -> J-1) |
o tools: |
| 8 |
that affects runs when SEAICEscaleSurfStress=.TRUE. (only for JFNK) |
- add a hack in "remove_comments_sed" (used only with TAF) for recent |
| 9 |
|
version of OpenMPI (shipped with FC.23): comment out the new header |
| 10 |
|
file "mpif-sizeof.h" which causes problems to TAF. |
| 11 |
|
o pkg/seaice: |
| 12 |
|
- change the termination criterion so that maxits (SEAICElinearIterMax) |
| 13 |
|
has an effect |
| 14 |
|
- unify iteration parameters for implicit solvers (JFNK and Picard) |
| 15 |
|
SEAICEnonLinIterMax replaces SEAICEnewtonIterMax/NPSEUDOTIMESTEPS |
| 16 |
|
SEAICElinearIterMax replaces SEAICEkrylovIterMax/SOLV_MAX_ITER |
| 17 |
|
SEAICEpreLinIterMax replaces SOLV_MAX_ITER in preconditioner |
| 18 |
|
SEAICEpreNL_IterMax replaces NPSEUDOTIMESTEPS in preconditioner |
| 19 |
|
SEAICEnonLinTol replaces JFNKgamma_nonlin |
| 20 |
|
- remove S/R SEAICE_FGMRES_DRIVER and put content into S/R SEAICE_JFKN |
| 21 |
|
- add new Picard-Krylov solver, compile with SEAICE_ALLOW_KRYLOV and |
| 22 |
|
use with SEAICEuseKrylov |
| 23 |
|
o pkg/seaice/seaice_lsr.F |
| 24 |
|
fix small bug: replace zetaZ by zetaZloc in S/R seaice_lsr_rhsu/v; only |
| 25 |
|
relevant if SEAICEuseStrImpCpl=T, and even then it does not seem to have |
| 26 |
|
an effect. |
| 27 |
|
o pkg/seaice: add two new parameters |
| 28 |
|
- SEAICEuseLSR to simplify the logic in seaice_dynsolver (this |
| 29 |
|
parameter is not in any namelist) |
| 30 |
|
- SEAICEusrPicardAsPrecon to allow s/r seaice_lsr to be used as |
| 31 |
|
a preconditioner for the non-linear Newton iteration of the JFNK |
| 32 |
|
solver |
| 33 |
|
o pkg/seaice/seaice_lsr.F: replace 1./SEAICE_deltaTdyn with recip_deltaT, |
| 34 |
|
affects some experiments at truncation level: |
| 35 |
|
- global_ocean.cs32x15.icedyn (11 digits), |
| 36 |
|
- global_ocean.cs32x15.seaice (11 digits), |
| 37 |
|
- seaice_itd (12 digits), seaice_itd.lipscomb07 (12 digits) -> update |
| 38 |
|
- also update global_ocean.cs32x15 adjoint and tangent-linear results |
| 39 |
|
o pkg/salt_plume & pkg/thsice: |
| 40 |
|
- for coupled set-up with pkg/thsice in ATM and pkg/salt_plume in OCN, |
| 41 |
|
connect salt_plume flux to ATM-OCN coupling pkgs interface: |
| 42 |
|
a) in ATM: also cumulate salt-plume flux in S/R THSICE_SALT_PLUME (for |
| 43 |
|
export to coupler interface) even without compiling pkg/salt_plume ; |
| 44 |
|
b) in OCN: apply coupler salt-plume flux to pkg/salt_plume field |
| 45 |
|
(saltPlumeFlux) just before exch call, in S/R SALT_PLUME_DO_EXCH. |
| 46 |
|
o pkg/dic: |
| 47 |
|
- use the updated seaice fraction (from seaice pkgs) for DIC forcing |
| 48 |
|
instead of the previous time-step value ; done in new S/R DIC_FIELDS_UPDATE |
| 49 |
|
called from the top of dic_biotic_forcing.F (instead of in DIC_FIELDS_LOAD); |
| 50 |
|
- move also update with values from ATM-OCN Coupler in the same new S/R |
| 51 |
|
(previously done in ocn_apply_import.F). |
| 52 |
|
o tools/adjoint_options: |
| 53 |
|
- specify explicitly "-f77" or "-f90" in default ad-optfile since TAF (default) |
| 54 |
|
has been changed on Jan 14, 2016. |
| 55 |
|
o pkg/ggl90: |
| 56 |
|
- add alternative discretisation of vertical shear (off by default), to |
| 57 |
|
compute the mean (@ grid-cell center) of vertical shear compon instead of |
| 58 |
|
vertical shear of mean flow (@ grid-cell center). |
| 59 |
|
- add correct parenthesis in ALLOW_GGL90_SMOOTH code to get the same truncated |
| 60 |
|
results on adjacent faces of cubed-sphere grids; this fix the restart. |
| 61 |
|
o pkg/atm_compon_interf: |
| 62 |
|
- skip time-ave over cpl_atmSendFrq of Sea-Level Pressure (atmSLPr) and just |
| 63 |
|
pass last value, stored directly before export to CPL ; |
| 64 |
|
Note: this affects results of Coupled set-up where OCN uses useImportSLP=T |
| 65 |
|
- remove atmSLPr from pickup files (no longer needed for restart) |
| 66 |
|
|
| 67 |
|
checkpoint65s (2016/01/13) |
| 68 |
|
o eesupp & genmake2: |
| 69 |
|
- first check for Function ETIME and, if it fails, then check for subroutine |
| 70 |
|
ETIME and consistent output; use the appropriate version in timers.F |
| 71 |
|
o model/src: |
| 72 |
|
- to check restart test, add option to apply EXCH to U,V earlier, just before |
| 73 |
|
integr_continuity; turned off by default. |
| 74 |
|
o pkg/dic: |
| 75 |
|
- remove CPP option USE_ATMOSCO2 (not needed) |
| 76 |
|
o tools/tst_2+2: |
| 77 |
|
- try to ignore difference between +0 and -0 in binary file, causing test |
| 78 |
|
to fail for no good reason. |
| 79 |
|
o eesupp & genmake2: |
| 80 |
|
- put back modif from Jinxuan Zhu - change etime fct call to S/R call - |
| 81 |
|
but also check (in genmake2) that test runs and returns meaningful results. |
| 82 |
|
o coupler pkgs: |
| 83 |
|
Finish implementation of optionally-exchanged variable switches (started on |
| 84 |
|
Nov 12) with addition of few more exchanged fields, including 2-way exchange |
| 85 |
|
of pkg/thsice vars to allow to use seaice dynamics (from pkg/seaice) & seaice |
| 86 |
|
advection in OCN component; this requires sequential coupling. |
| 87 |
|
coupler (pkg/atm_ocn_coupler): |
| 88 |
|
- add argument msgUnit and iter number to CPL_SEND/RECV_ATM/OCN_FIELDS |
| 89 |
|
routines (useful for debug). |
| 90 |
|
- only export/import optionally exchanged fields (RunOff, seaice, Salt-Plume |
| 91 |
|
flux, DIC fields) if corresponding switch is ON. |
| 92 |
|
- add option to export RunOff to OCN (to use for DIC river input) |
| 93 |
|
- add 2-way thSIce vars exchange; check for consistent cpl_sequential setting. |
| 94 |
|
components (pkg/atm_ & ocn_compon_interf): |
| 95 |
|
- to save memory space in ATM & OCN comp: add some #ifdef ALLOW_${PKG} around |
| 96 |
|
optionally exchanged fields; add a check & stop in cpl_readparms.F. |
| 97 |
|
ATMCPL.h: ALLOW_LAND for RunOff, ALLOW_THSICE for seaice, ALLOW_AIM for CO2; |
| 98 |
|
OCNCPL.h: ALLOW_SALT_PLUME, ALLOW_DIC for DIC, ALLOW_THSICE for 2-W thsice. |
| 99 |
|
- rename: fracIce -> sIceFrac_cpl (<- match coupler var name) |
| 100 |
|
+ in ATM: fracIceTime -> sIceFracTime ; seaIceTime -> sIceMassTime. |
| 101 |
|
- add 2-way thSIce vars exchange ; add Salt-Plume flux ; add RunOff in OCN. |
| 102 |
|
- hold in common block coupler optionally-exchanged variable switch |
| 103 |
|
and set default "useImportXXX" accordingly; + check & stop if inconsistent. |
| 104 |
|
- add diagnostics for all imported fields from coupler (in both OCN & ATM); |
| 105 |
|
this is intended to replace the OCN cplFldtave.* output files (not updated |
| 106 |
|
to contain new additional exchanged fields). |
| 107 |
|
o pkg/dic: |
| 108 |
|
- fix an other bug (also from 2014/08/30) in dic_atmos.F, in dic_int1=3 code. |
| 109 |
|
o pkg/thsice: |
| 110 |
|
- when coupled to ATM (useCoupler) with thSIce_skipThermo=T, skip reading |
| 111 |
|
and writing of thsice pickup files. |
| 112 |
|
o pkg/atm_compon_interf: |
| 113 |
|
- move all field individual export-call out of cpl_export_import_data.F |
| 114 |
|
into new S/R ATM_EXPORT_FIELDS |
| 115 |
|
o pkg/atm_compon_interf: |
| 116 |
|
- store state variables (for now, only thSIce fields) just before beeing |
| 117 |
|
exported (in cpl_export_import_data.F, like on ocean side) instead of from |
| 118 |
|
atm_store_my_data.F like all exported fluxes. |
| 119 |
|
- new version of pickup_cpl: write field names into meta file and read meta |
| 120 |
|
file to find field postion in pickup. Also only write/read fields meeded for |
| 121 |
|
restart (same logic as main pickup file ; also using pickupStrictlyMatch) |
| 122 |
|
o pkg/dic: |
| 123 |
|
- fix bug (added on 2014/08/30) in dic_atmos.F for the case dic_int1= 2 or 3. |
| 124 |
|
o pkg/seaice: add new parameter SEAICEpressReplFac to choose between |
| 125 |
|
pressure replacement method (=1., default) or original Hibler (1979) (=0.) |
| 126 |
|
value can be from domain [0,1] to average between the two methods |
| 127 |
|
o pkg/atm_phys: |
| 128 |
|
- allow to provide 2-d map of albedo and mixed-layer depth from files (but |
| 129 |
|
hold fixed in time). |
| 130 |
|
|
| 131 |
|
checkpoint65r (2015/12/21) |
| 132 |
|
o pkg/seaice: |
| 133 |
|
fix bug in tridiagonal solvers for SEAICE_OLx/y>0, this affects the JFNK |
| 134 |
|
solver (offline.dyn_jfnk) and global_ocean.cs32x15.seaice -> updated |
| 135 |
|
o pkg/seaice: |
| 136 |
|
- fix a bug in computing areaS in (J-J -> J-1) that affects runs |
| 137 |
|
when SEAICEscaleSurfStress=.TRUE., |
| 138 |
|
- apply areaW and areaS in S/R seaice_calc_lhs |
| 139 |
o pkg/atm_phys: |
o pkg/atm_phys: |
| 140 |
- add diagnostics for 3-D, Nr+1 levels diagnostics of radiative fluxes |
- add diagnostics for 3-D, Nr+1 levels diagnostics of radiative fluxes |
| 141 |
(shortwave & longwave, net & downward) and diagnostics of temp. tendency |
