|
o add parameter rotateGrid and Euler angles EulerPhi/Theta/Psi. For |
| 8 |
|
usingSphericalGrid, this allows to define the rotated grid coordinates |
| 9 |
|
via phiMin/thetaMin/dxSpacing/dySpacing, etc., but then re-compute the |
| 10 |
|
geographical coordinates according to the inverse of the rotation defined |
| 11 |
|
by the Euler angles, so that Coriolis parameter and online-interpolation by |
| 12 |
|
exf works with the geographical coordinates on XC/YC/XG/YG. |
| 13 |
|
Naturally, this feature does not work with all packages, so some |
| 14 |
|
combinations are prohibited in config_summary (flt, flt_zonal, ecco, |
| 15 |
|
profiles), because there the coordinates are assumed to be regular |
| 16 |
|
spherical grid coordinates. |
| 17 |
|
o pkg/gmredi,ctrl,ecco,autodiff,grdchk and model/src,inc: |
| 18 |
|
- introduce isopycnal diffusion coefficient control. |
| 19 |
|
o tools/adjoint_options: |
| 20 |
|
- additional control vector components. |
| 21 |
|
o pkg/mnc: have mnc create marginally meaning full coordinate variables |
| 22 |
|
(that is the grid indices) if usingCurvilinearGrid and NOT EXCH2 |
| 23 |
|
o pkg/mypackage: |
| 24 |
|
- add example of read/write pickup for state-var ; |
| 25 |
|
- add entry points to the main code for state-vars diags & write-pickup. |
| 26 |
|
o pkg/exf: rewrite of exf_getffieldrec.F to properly deal with year |
| 27 |
|
transitions for useExfYearlyFields |
| 28 |
|
- add new subroutine that determines the file to read from for |
| 29 |
|
use*YearlyFields = .TRUE. and .FALSE. |
| 30 |
|
- add a verification experiment to global_with_exf that tests |
| 31 |
|
useExfYearlyFields with USE_EXF_INTERPOLATION defined |
| 32 |
|
o pkg/obcs/exf: add useOBCSYearlyFields (=.FALSE.) to obcs with exf in |
| 33 |
|
analogy to useExfYearlyFields; rearrange obcs_prescribe_read: two new |
| 34 |
|
subroutines (which could be generated from a template, because they are |
| 35 |
|
almost identical), for now they are included in obcs_prescribe_read.F for |
| 36 |
|
simplicity |
| 37 |
|
o pkg/exf: |
| 38 |
|
- add a little more diagnostic to exf_interp_read (in analogy to |
| 39 |
|
mds_read_field, can be turned off with debugLevel < debugLevA=1) |
| 40 |
|
- improve vectorizability of exf_interp for TARGET_NEC_SX, makes code |
| 41 |
|
ugly but fast by unrolling short inner loops, inserting a unroll=8 |
| 42 |
|
directive in routine lagran, and splitting a loop and making do while the |
| 43 |
|
outermost loop (the latter requires the intoduction of index arrays) |
| 44 |
|
o pkg/obcs: replace obcs_apply_area/heff/hsalt/hsnow with obcs_apply_seaice |
| 45 |
|
o pkg/seaice: moved DIFFERENT_MULTIPLE from seaice_model to seaice_dynsolver |
| 46 |
|
http://forge.csail.mit.edu/pipermail/mitgcm-devel/2008-January/003173.html |
| 47 |
|
o verification/seaice_obcs: updated for restart test and latest options |
| 48 |
|
o pkg/seaice: add a new flag SEAICEuseTEM to use a slightly different |
| 49 |
|
ice rheology (so-called truncated ellipse, that gets rid of tensile stress); |
| 50 |
|
for now this is only available for the C-grid code and also within |
| 51 |
|
#ifdef SEAICE_ALLOW_TEM, because this option may slow down the EVP code |
| 52 |
|
|
| 53 |
|
checkpoint59m |
| 54 |
|
o pkg/seaice: use different time constant for melting (SEAICE_gamma_t) |
| 55 |
|
and freezing (SEAICE_gamma_t_frz) ice due to mixed layer temperature |
| 56 |
|
o gad_som : fix flux output (& diagnostics) to have same units as other |
| 57 |
|
advection scheme fluxes (was previously multiplied by deltaT). |
| 58 |
|
o added verification/seaice_obcs both to test seaice open boundaries |
| 59 |
|
and to provide an example matlab scrpt for generating them |
| 60 |
|
o added verification/lab_sea/input.salt_plume for testing pkg/salt_plume |
| 61 |
|
o pkg/salt_plume: clean up salt_plume_frac.F to |
| 62 |
|
remove redundancy in PlumeMethod 1 and 4 |
| 63 |
|
o pkg/kpp: added saltplume diagnostics |
| 64 |
|
o pkg/obcs and pkg/seaice: |
| 65 |
|
- do not set uice and vice to zero when OB*icefile are unspecified |
| 66 |
|
- OBCS_SEAICE_AVOID_CONVERGENCE is undefined by default |
| 67 |
|
- moved seaice tracer obcs after call to seaice_growth |
| 68 |
|
o pkg/salt_plume: added various options for salt plume depth |
| 69 |
|
criterion and for vertical distribution of the salt |
| 70 |
|
|
| 71 |
|
checkpoint59l |
| 72 |
|
o pkg/ptracers: new version of ptracers pickup: |
| 73 |
|
read meta file and write only fields which are needed to restart. |
| 74 |
|
( same logic as main pickup file ; also using pickupStrictlyMatch ) |
| 75 |
|
o pkg/seaice: |
| 76 |
|
- add timescale for melting due to warm mixed layer as a means of |
| 77 |
|
setting SEAICE_availHeatFrac more conveniently |
| 78 |
|
- add a CPP-flag/runtime parameter check for flooding algorithm |
| 79 |
|
- reformulated availHeat in seaice_growth.F to be independent of AREA |
| 80 |
|
o change units attribute of EmPmR netcdf variables to kg/m^2/s to reflect recent |
| 81 |
|
unit changes |
| 82 |
|
o pkg/obcs: added OBCS_SEAICE_AVOID_CONVERGENCE constraint |
| 83 |
|
o cg2d.F: add 3 compiler directives that speed up this routine by 30% on a NEC |
| 84 |
|
SX vector computer. |
| 85 |
|
o pkg/seaice: |
| 86 |
|
- removed SEAICE_FFIELDS.h and seaice_get_forcing.F |
| 87 |
|
seaice forcing fields can now be read only through pkg/exf |
| 88 |
|
- removed some unused halos |
| 89 |
|
o no longer write pickup from THE_MODEL_MAIN but always from FORWARD_STEP |
| 90 |
|
o pkg/exf: added useRelativeWind EXF_PARAM.h option for subtracting U/VVEL |
| 91 |
|
or U/VICE from U/VWIND before computing U/VSTRESS |
| 92 |
|
|
| 93 |
|
checkpoint59k |
| 94 |
|
o pkg/seaice: ICE2WATR=SEAICE_rhoIce/rhoConst for consistency between |
| 95 |
|
dynamics and thermodynamics. Set ICE2WATR=0.92 to reproduce older results. |
| 96 |
|
o fix un-initialised variable problem (in mom_vecinv & shap_filt): |
| 97 |
|
all experiments pass when compile with un-initialised var. checking option. |
| 98 |
|
o added pkg/salt_plume |
| 99 |
|
o script to test restart (for now, in MITgcm_contrib/jmc_script) |
| 100 |
|
o pkg/seaice: new read/write pickup version. |
| 101 |
|
read meta file and write only fields which are needed to restart. |
| 102 |
|
( same logic as main pickup file ; also using pickupStrictlyMatch ) |
| 103 |
|
o pkg/seaice: fix bug in seaice_ocean_stress (call of seaice_calc_strainrates) |
| 104 |
o lab_sea.hb87: modify the domain & update output.hb87.txt : |
o lab_sea.hb87: modify the domain & update output.hb87.txt : |
| 105 |
lat-long grid & no-slip BC in seaice-dynamics produce different sigma12 |
lat-long grid & no-slip BC in seaice-dynamics produce different sigma12 |
| 106 |
at j=1 & j=Ny+1 : this case is not treated correctly in the restart |
at j=1 & j=Ny+1 : this case is not treated correctly in the restart |
