o pkg/seaice |
| 8 |
|
- beginning code for a seaice tracer package, |
| 9 |
|
but currently only used for seaice age: SEAICE_AGE |
| 10 |
|
SEAICE_num = 4 |
| 11 |
|
iTracer = 1: area-weighted ice age |
| 12 |
|
= 2: volume-weighted ice age |
| 13 |
|
= 3, 4: template for one-year vs. multi-year ice |
| 14 |
|
data.seaice has new namelist SEAICE_PARM03 for arrays related to |
| 15 |
|
SEAICE_num |
| 16 |
|
|
| 17 |
|
checkpoint62t (2011/03/05) |
| 18 |
|
o pkg/obcs: |
| 19 |
|
- obcs_apply_uv.F: change to a 2 steps method, first tangential component; |
| 20 |
|
then normal component. This ensures that the normal component is set |
| 21 |
|
correctly even when it conficts with tangential setting from an other OB. |
| 22 |
|
Affects results of test-experiment seaice_obcs: update the output.txt |
| 23 |
|
o pkg/obcs: |
| 24 |
|
- add code to monitor statistics of dynamical fields at OB. |
| 25 |
|
- take OBCS_BALANCE code out of obcs_calc.F into new S/R OBCS_BALANCE_FLOW : |
| 26 |
|
- fix to OBCS_BALANCE code (right hFac ; deal with simple OB intersection). |
| 27 |
|
- change default: balance the Net inflow through all OB (instead of balancing |
| 28 |
|
each OB separately); keep the old method if setting OBC_balanceFacX < 0. |
| 29 |
|
- switch on useOBCSbalance in dome experiment: only correct Western OB outflow |
| 30 |
|
to match Nortern OB inflow (OBCS_balanceFacN=0). |
| 31 |
|
o pkg/seaice: |
| 32 |
|
- redefined actual sea ice age to be ICEAGE/HEFF ifdef SEAICE_AGE_VOL |
| 33 |
|
o pkg/seaice (seaice_growth v 1.113): |
| 34 |
|
- reverting seaice_growth to v 1.111 in order to have code with exact bit |
| 35 |
|
compatibility with MITgcm_contrib/ifenty/Fenty_seaice_thermo_code_merge |
| 36 |
|
CPP option SEAICE_OCN_MELT_ACT_ON_AREA removed in v 1.112 is reintroduced |
| 37 |
|
runtime flag SEAICEareaFormula is kept but is inactive |
| 38 |
|
o model/src: |
| 39 |
|
- add new param to scale curvilinear grid distance and area when using |
| 40 |
|
a different sphere radius from the grid-files. |
| 41 |
|
- test/check multi-threads EXCH applied to local variable (cg2d_x) |
| 42 |
|
o adjoint: |
| 43 |
|
- enable adjoint of Stevens OB |
| 44 |
|
- add dummy_in_dynamics to enable extraction of ADJrhoinsitu |
| 45 |
|
(a bit delicate because of potentially modified adj. common block structure; |
| 46 |
|
current switch is ALLOW_AUTODIFF_MONITOR_DIAG, could be changed later) |
| 47 |
|
|
| 48 |
|
checkpoint62s (2011/02/15) |
| 49 |
|
o pkg/seaice (seaice_growth v 1.112): |
| 50 |
|
- introduce SEAICEareaFormula run time parameter, which selects the recipe for |
| 51 |
|
computing the ice cover tendency from effective thickness tendencies. Include |
| 52 |
|
Ian Fenty's formula. |
| 53 |
|
- remove 'undef SEAICE_OCN_MELT_ACT_ON_AREA' which may now be achieved using |
| 54 |
|
SEAICEareaFormula. |
| 55 |
|
- simplify notations for the various d_HEFF/d_AREA terms. |
| 56 |
|
o pkg/gmredi: |
| 57 |
|
- add Boundary-Value-Problem bolus transport (Ferrari etal, OM 2010) code |
| 58 |
|
from Christopher Wolfe (UCSD); add partial cell factor in vertical derivative; |
| 59 |
|
add a verification test-run (front_relax.bvp) to test GM_useBVP. |
| 60 |
|
o pkg/seaice (seaice_growth v 1.111): |
| 61 |
|
- for SEAICE_DO_OPEN_WATER_GROWTH, replace Gael's implementation with Ian's. |
| 62 |
|
- the new SEAICE_DO_OPEN_WATER_MELT allows open-water air-sea heat fluxes to |
| 63 |
|
also melt ice. |
| 64 |
|
o pkg/seaice: |
| 65 |
|
- McPhee formula for Ice-Ocean fluxes (provided by Ian Fenty). |
| 66 |
|
- can be used by #define MCPHEE_OCEAN_ICE_HEAT_FLUX in SEAICE_OPTIONS.h |
| 67 |
|
o pkg/cheapaml: |
| 68 |
|
- from Nico Wienders: New version of this package. |
| 69 |
|
o pkg/flt: |
| 70 |
|
- add CPP options to prevent floats to re-enter the opposite side of |
| 71 |
|
a periodic domain (default: keep periodicity) |
| 72 |
|
o pkg/gmredi: |
| 73 |
|
- apply exchange to GM_PsiX,GM_PsiY to get valid values near CS-corners |
| 74 |
|
(needed for multi-dim advection). |
| 75 |
|
- switch on GM Advective form in global_ocean.cs32x15 and update output.txt |
| 76 |
|
o model/src: |
| 77 |
|
- fix wrong re-setting of addMass array (ALLOW_ADDFLUID) for atmospheric run. |
| 78 |
|
o tutorial_tracer_adjsens |
| 79 |
|
- extend to NLFS and replace maskC by hFacC |
| 80 |
|
(change reference output accordingly) |
| 81 |
|
|
| 82 |
|
checkpoint62r (2011/01/24) |
| 83 |
|
o testreport: |
| 84 |
|
- add option -deloutp (-do) to remove output file after successful run |
| 85 |
|
- add option -mfile (-mf) for MPI machile-file and for each test-exp, |
| 86 |
|
extract exact list of procs from this file ; adjust COMMAND by |
| 87 |
|
replacing TR_MFILE & TR_NPROC with local machile-file & Nb of MPI procs. |
| 88 |
|
o pkg/ecco: replace old ineffective way of penalizing deviations from |
| 89 |
|
first guess (of obcs) with code by Matt Mazloff |
| 90 |
|
o pkg/ctrl: add code that allows the use of ALLOW_OBCS?_CONTROL without |
| 91 |
|
exf/cal |
| 92 |
|
- ctrl_init: fix initialisation (computation of diffrec) for obcs-ctrl |
| 93 |
|
and handle case of obcs?period == 0 |
| 94 |
|
Not affected by these changes: There is still an inconsistency in |
| 95 |
|
the computation of start/endrec for the obcs variables for ALLOW_CAL |
| 96 |
|
defined (see comment by Menemenlis, 7-Mar-2003) |
| 97 |
|
- make S/R ctrl_get_gen_rec return something meaningful even if |
| 98 |
|
ALLOW_CAL is not defined |
| 99 |
|
- ctrl_getobcs?: simplify code so that it does not need to use |
| 100 |
|
S/R exf_swapfields |
| 101 |
|
o testreport: |
| 102 |
|
allow to test MPI with different number of processors for each experiment: |
| 103 |
|
create file "SIZE.h.mpi" in each build dir. |
| 104 |
|
Note: update of "-command" argument not yet implemented. |
| 105 |
|
o model/src, pkg/autodiff, pkg/ecco, pkg/seaice: |
| 106 |
|
alleviate the need for additional 3D tapes when using |
| 107 |
|
the non-inear free surface in the adjoint. This is done |
| 108 |
|
by adding an 'update' of hfacc etc. to their current |
| 109 |
|
value at the beginning of forward_step.F. |
| 110 |
|
o pkg/seaice |
| 111 |
|
seaice_lsr: move stress-divergence computations out of outer pseudo- |
| 112 |
|
timestepping loop |
| 113 |
|
o pkg/obcs/obcs_prescribe_read.F: move 'CALL OBCS_EXTERNAL_FIELDS_LOAD' |
| 114 |
|
up, so that the calls of the ctrl_* subroutines are really at the end |
| 115 |
|
of the routine. |
| 116 |
|
o pkg/gmredi: |
| 117 |
|
allow to specify a 2-D horizontal map and a 1-D vertical profil |
| 118 |
|
as scaling factor for Isopycnal diffusivity (Redi) and GM diffusivity. |
| 119 |
|
o pkg/seaice: |
| 120 |
|
move lsr iterations from seaice_dynsolver to seaice_lsr. |
| 121 |
|
o pkg/seaice: |
| 122 |
|
reduce memory footprint of seaice mutldim advection tapes, |
| 123 |
|
by using a 2D tape independent of the generic_advdiff ones, |
| 124 |
|
and setting GAD_AREA=1 etc. rather than GAD_AREA=101 etc. |
| 125 |
|
|
| 126 |
|
checkpoint62q (2010/12/29) |
| 127 |
|
o model/src: |
| 128 |
|
- check horizontal grid-spacing for unset or zero/negative values. |
| 129 |
|
- change AD test hs94.1x64x5 to be truly a 2-D set-up. |
| 130 |
|
o pkg/flt: |
| 131 |
|
- use (recent) mdsio S/R MDS_READVEC_LOC instead of local FLT_MDSREADVECTOR |
| 132 |
|
- precision of input and output files set according to readBinaryPrec |
| 133 |
|
and writeBinaryPrec (previously always 64.b), pickup remains at 64 bits. |
| 134 |
|
- initial float position from tiled file was not converted to index space |
| 135 |
|
(looks like a bug): fixed to make it similar to initial pos. global file. |
| 136 |
|
o global_ocean.cs32x15: |
| 137 |
|
change SIZE.h of AD set-up to get same tiling as with MPI. |
| 138 |
|
Update output_adm, output_adm.thsice (pass@14) & output_adm.seaice (fail@11) |
| 139 |
|
o model/src: |
| 140 |
|
add flag to control printing of domain fields (bathymetry, hFac ...) in |
| 141 |
|
ini_mask_etc (call to plot_fieds_xy*). |
| 142 |
|
o pkg/thsice: |
| 143 |
|
if useEXF, some forcing fields are not valid in overlap: fixed by computing |
| 144 |
|
over the interior only + apply EXCH at the end (like with SEAICE advection). |
| 145 |
|
o pkg/mdsio: |
| 146 |
|
- add 2 arguments to S/R MDS_PASS_R4/8toRL/S for overlap size of buffer |
| 147 |
|
to copy to/from, so that it can be used to replace MDS_PASS_WH_R8toRL/RS. |
| 148 |
|
- change barrier call for safe multi-threads access to 3-D shared buffer. |
| 149 |
|
- MDS_READ/WRITEVEC_LOC use buffers from MDSIO_BUFF_3D.h (instead of local ones) |
| 150 |
|
- replace call to MDS_PASS_WH_R4/8toRL with call to MDS_PASS_R4/8toRL and |
| 151 |
|
remove the 4 S/R MDS_PASS_WH_R4/8toRL/S. |
| 152 |
o pkg/flt: |
o pkg/flt: |
| 153 |
- add fourth-order Runge-Kutta integration |
- add fourth-order Runge-Kutta integration |
| 154 |
- add basic exch2 support (only 1 facet supported so far!) |
- add basic exch2 support (only 1 facet supported so far!) |
