|
o pkg/offline: |
| 8 |
|
- comment out unused field-array: ICEM, ConvectCount, hflx[01], icem[01]; |
| 9 |
|
- add S/R OFFLINE_CHECK to print offline parameter summary |
| 10 |
|
and stop if loading a file that is not used; |
| 11 |
|
- enable to calculate GMRedi tensor, KPP mixing and convective index |
| 12 |
|
when the corresponding file(s) is/are not specified (but pkg is used). |
| 13 |
|
o OpenAD: |
| 14 |
|
- do not define OAD_DEBUG (in tools/adjoint_options/adjoint_oad) to get |
| 15 |
|
smaller standard output) and generate new (smaller) output (on baudelaire |
| 16 |
|
using gfortran with -ieee) for exp. tutorial_tracer_adjsens |
| 17 |
|
o model/src: |
| 18 |
|
- call EXTERNAL_FORCING_SURF outside bi,bj loops (in do_oceanic_phys.F), |
| 19 |
|
(where external_forcing_adjust was called) and change list of arguments; |
| 20 |
|
- merge external_forcing_adjust.F into external_forcing_surf.F |
| 21 |
|
- put surface relaxation of SST & SSS in new S/R (forcing_surf_relax.F) |
| 22 |
|
which also contains balancing surface relaxation (ALLOW_BALANCE_RELAX, |
| 23 |
|
previously in file "balance_relax.F", now removed); remove corresponding |
| 24 |
|
arrays in FFIELDS.h. |
| 25 |
|
- EXTERNAL_FORCING_SURF is now called when using pkg/offline; implement |
| 26 |
|
a hack for getting back surfaceForcingS (loaded from file) when using |
| 27 |
|
ALLOW_OLD_VIRTUALFLUX (pkg/dic, in DIC_OPTIONS.h) in offline set-up. |
| 28 |
|
- update output of AD test experiment global_ocean.cs32x15.seaice_dynmix |
| 29 |
|
(was getting only 11 digits for AD-grad, due to different truncation |
| 30 |
|
error in AD code). |
| 31 |
|
|
| 32 |
|
checkpoint64j (2013/07/04) |
| 33 |
|
o pkg/offline: |
| 34 |
|
- to enable the use of other features with pkg offline (e.g., obcs), |
| 35 |
|
also call S/R DO_OCEANIC_PHYS in offline run - more modifs to come. |
| 36 |
|
- comment out "allowFreezing" (now active) in 2 offline testing exp. |
| 37 |
|
o pkg/exf ALLOW_RUNOFTEMP |
| 38 |
|
- fix sign and make compatible with temp_EvPrRn .NE. UNSET_RL |
| 39 |
|
- ahdded RUNOFTEMP test to verification/global_ocean.cs32x15/input.seaice |
| 40 |
|
- changes verification/global_ocean.cs32x15/results/output.seaice.txt |
| 41 |
|
o pkg/atm_phys: |
| 42 |
|
- allows to add some damping on uVel,vVel (strength only function of k). |
| 43 |
|
o verification, ad-tests: |
| 44 |
|
- reduce length of the simulation for AD test: global_ocean.cs32x15.seaice, |
| 45 |
|
global_ocean_ebm and offline_exf_seaice.thsice. |
| 46 |
|
o verification/halfpipe_streamice: |
| 47 |
|
- found a bug in s/r pkg/streamice/streamice_advect_thickness which caused |
| 48 |
|
flux input boundary conditions to be ignored; a fix for this bug changed |
| 49 |
|
verification results for forward test. |
| 50 |
|
- add adjoint test. |
| 51 |
|
o pkg/ptracers: |
| 52 |
|
- allow to restart without SOM pickup (resetting SOM to zero). |
| 53 |
|
o pkg/gmredi: |
| 54 |
|
- New parameterisation for the calculation of K and (GM_PsiX,GM_PsiY) added. |
| 55 |
|
- It uses mixing length theory and suppression by steering level effects to |
| 56 |
|
calculate a diffusivity used in the Redi tensor (see Bates et al., submitted |
| 57 |
|
to JPO, for more details). |
| 58 |
|
- It also uses the diffusivity to calculate an eddy induced streamfunction |
| 59 |
|
based on a PV closure (rather than a buoyancy closure as in GM). |
| 60 |
|
- New files added to pkg/gmredi: |
| 61 |
|
gmredi_k3d.F calculates the diffusivity for the Redi tensor and the eddy |
| 62 |
|
induced overturning streamfunction (called from gmredi_calc_tensor) |
| 63 |
|
gmredi_calc_eigs.F calculates the eigenvalues and eigenvectors required |
| 64 |
|
for use in gmredi_k3d |
| 65 |
|
gmredi_calc_urms.F calculates the the rms eddy velocity used to calculate |
| 66 |
|
the eddy diffusivity |
| 67 |
|
|
| 68 |
|
checkpoint64i (2013/06/18) |
| 69 |
|
o pkg/cheapaml: |
| 70 |
|
- take src files from MITgcm_contrib/verification_other/offline_cheapaml/code |
| 71 |
|
that enable the use of seaice (pkg/thsice thermo & pkg/seaice dynamics) |
| 72 |
|
with pkg/cheapaml. |
| 73 |
|
o utils/python: add subpackage for cubed sphere function, first example is |
| 74 |
|
simple cs.pcol to plot 2D fields on a map |
| 75 |
|
o pkg/streamice: |
| 76 |
|
- This is a new package in MITgcm, which solves dynamic equations for ice |
| 77 |
|
sheets and ice streams |
| 78 |
|
- At the moment it is independent of atmosphere/ocean dynamics, or any |
| 79 |
|
other physical packages in MITgcm, even ShelfIce (although it is anticipat- |
| 80 |
|
ed that this will change) |
| 81 |
|
- There is a new verification exercise that tests it, halfpipe_streamice, |
| 82 |
|
evolves a 40x80 km ice stream/ice shelf (at coarse resolution) in a |
| 83 |
|
rectangular embayment |
| 84 |
|
- halfpipe_streamice is forward-only for now, will have TAF test soon |
| 85 |
|
- for questions, email dgoldber@mit.edu |
| 86 |
|
o pkg/thsice: |
| 87 |
|
- fix filling of snow-precip diagnostic (SIsnwPrc) (left from the removing |
| 88 |
|
of snowPrc from common bloc, on May 2nd, thsice_step_fwd.F revision 1.40); |
| 89 |
|
- remove diagnostics 'SI_FrcFx' ( now identical to 'SI_Fract' with new |
| 90 |
|
call sequence: ice-Thermo(thsice),ice-Dyn,ice-Advect ); |
| 91 |
|
- allow precip from pkg/cheapaml to make snow over seaice. |
| 92 |
|
o pkg/cfc: |
| 93 |
|
- move in separated header file (CFC_ATMOS.h) time-serie arrays of Atmos CFC |
| 94 |
|
- remove atmos CFC 2-D arrays from common bloc (now local variables) |
| 95 |
|
- change some hard-coded constant to run time parameter for reading and |
| 96 |
|
and interpolating atmospheric CFC ; keep same default as previously. |
| 97 |
|
- more flexible reading of Atmos CFC (number of records no longer hard-coded) |
| 98 |
|
- put arguments in standard order: myTime, myIter, myThid |
| 99 |
|
- use standard S/R GET_PERIODIC_INTERVAL for time interpolation of |
| 100 |
|
atmospheric CFC ; fix for the case myIter < PTRACERS_iter0. |
| 101 |
|
- fix calculation of surf tendencys for partial-cell and/or Non-Lin Free-Surf |
| 102 |
|
- new routine to print summary of CFC params and check for consistency. |
| 103 |
|
o pkg/seaice: add uice/vice to the parameter list of s/r seaice_advdiff, |
| 104 |
|
similar to thsice_advdiff. |
| 105 |
|
Note that for the B-grid case the routine parameters uc/vc are overwritten. |
| 106 |
|
o pkg/cfc: |
| 107 |
|
- change time interpolation for atmospheric CFC-11 (now same as for CFC-12); |
| 108 |
|
update output (CFC-11) of experiment cfc_example and tutorial_cfc_offline. |
| 109 |
|
- fix interpolation of atmphspheric CFC between Sorthern and Northern |
| 110 |
|
hemisphere value. |
| 111 |
|
o pkg/seaice: |
| 112 |
|
- allow to use seaice dynamics without pkg/exf (e.g., using pkg/cheapaml) |
| 113 |
|
o pkg/seaice: add Adams-Bashforth2 time discretization for ice dynamics; |
| 114 |
|
so far only for JFNK-solver, turn on with SEAICEuseAB2 = .TRUE. |
| 115 |
|
- requires an additional time level that is stored in the pickup |
| 116 |
|
- you can start with AB2 from a pickup without this time level with |
| 117 |
|
pickupStrictlyMatch = .false. |
| 118 |
|
|
| 119 |
|
checkpoint64h (2013/05/26) |
| 120 |
|
o pkg/cheapaml: |
| 121 |
|
- replace one ()**.5 with SQRT + use temp var "cdu = tau/Du" (coare3_flux); |
| 122 |
|
affect machine truncation (but exp cheapAML_box still pass with 13 digits). |
| 123 |
|
- consistent treatment of uWind,vWind location: assume everywhere in |
| 124 |
|
pkg/cheapaml that they are on C-grid (@ uVel,vVel location) |
| 125 |
|
(Note: was already the case for Tair,Qair advection); |
| 126 |
|
add option (INCONSISTENT_WIND_LOCATION) to recover old results. |
| 127 |
|
- compute diabatic forcing only in the interior (excluding overlap regions) |
| 128 |
|
- fill in array "Qsw" (for short-wave heating); |
| 129 |
|
- add diagnostic for precip ; fill-in diagnostics for cheapAML state vars |
| 130 |
|
before any update (consistent with MITgcm state var diagnostics); |
| 131 |
|
- cheapaml_fields_load.F & cheapaml_init_varia.F : only fill outer edges if |
| 132 |
|
non periodic ; + adjusted for uWind,vWind (C-grid). |
| 133 |
|
o pkg/seaice: |
| 134 |
|
- remove dependence of pkg/seaice versus pkg/exf (file: pkg/pkg_depend) and |
| 135 |
|
add explicitly pkg/exf in experiments that currently use pkg/seaice. |
| 136 |
|
- allows to compile pkg/seaice without pkg/exf. |
| 137 |
|
o tools/OAD_support: |
| 138 |
|
- use a local copy (ourRWCPinBd) to ensure index ourRWCP stays within bounds |
| 139 |
|
of array "ourStepOf" in function rvNextAction (revolve.F90). |
| 140 |
o pkg/aim_compon_interf renamed to pkg/atm_compon_interf |
o pkg/aim_compon_interf renamed to pkg/atm_compon_interf |
| 141 |
- change pkg name (to be used with other atmospheric physics pkg) |
- change pkg name (to be used with other atmospheric physics pkg) |
| 142 |
but by-pass CVS when making the new pkg so that we keep the CVS history. |
