|
|

o real fresh water flux implemented with non-linear free-surface. |
o added 2*Omega*Cos(phi)*W to u equations (non-hydrostatic Coriolis term) |
| 7 |
|
New routine: mom_u_coriolis_nh() |
| 8 |
|
o fixed sign of non-hydrostatic metric terms in u and v equations. |
| 9 |
|
Depend on correct sign of gravitySign. |
| 10 |
|
o added work.pc* to .cvsignore in aim directories using ifc |
| 11 |
|
o introduced flag for controllin non-hydrostatic metric terms |
| 12 |
|
o removed gravitySign from PARM04 |
| 13 |
|
o switched to g77/ifc from pgf77 in aim experiments |
| 14 |
|
|
| 15 |
|
checkpoint46l_post |
| 16 |
|
o made convective adjustment work with pressure coordinates: |
| 17 |
|
- changed the direction of k-loop in convective_adjustment.F for the |
| 18 |
|
case of pressure coordinates (OCEANICP,ATMOSPHERIC buoyancyRelation) |
| 19 |
|
- adjusted the reference pressure k-index in convective_adjustment.F |
| 20 |
|
- adjusted the convection condition in convect.F (in analogy to |
| 21 |
|
calc_ivdc.F) |
| 22 |
|
- convective_adjustment no longer computes anything on the halos |
| 23 |
|
- removed the warnings about negative salinity from find_rho.F and |
| 24 |
|
find_alpha.F; instead the new routine look_for_neg_salinity, called |
| 25 |
|
at the beginning of find_rho, find_alpha, and find_beta, does a |
| 26 |
|
check of the entire slice, if CPP-option |
| 27 |
|
CHECK_SALINITY_FOR_NEGATIVE_VALUES is defined |
| 28 |
|
checkpoint46l_pre |
| 29 |
|
|
| 30 |
|
checkpoint46k_post |
| 31 |
|
o fixed the verification/global_ocean.90x40x15 experiment: |
| 32 |
|
- new bathymetry (the world according to A., JMC, and M.) |
| 33 |
|
- new initial fields and forcing fields (*.bin files) |
| 34 |
|
- new POLY3.COEFFS (for the next release one should switch to a full |
| 35 |
|
equation of state: JMD95P or MDJWF) |
| 36 |
|
- fixed several errors and redundancies in the data file |
| 37 |
|
- experiment uses looped cells |
| 38 |
|
- added matlab directory with diagnostic scripts for plotting of output |
| 39 |
|
|
| 40 |
|
o S/R aim_initialise.F replace S/R aim_init from file aim_do_inphys.F: |
| 41 |
|
- read AIM physics parameters from a file (data.aimphys) |
| 42 |
|
- set defaults values = F.Molteni paper (Clim.Dyn., 2002) |
| 43 |
|
|
| 44 |
|
checkpoint46j_post |
| 45 |
|
o split calc_exact_eta in 2 S/R : integr_continuity & update_etaH |
| 46 |
|
o move wVel computation at the end of the time step, in S/R integr_continuity |
| 47 |
|
o create specific S/R to exchange T,S before DYNAMICS (for stagger time step) |
| 48 |
|
o update timeave pkg for wVel diagnostic. |
| 49 |
|
checkpoint46j_pre |
| 50 |
|
|
| 51 |
|
checkpoint46i_post |
| 52 |
|
o Clean up AIM package (and keep the results unchanged): |
| 53 |
|
include CPP_OPTION and use IMPLICT NONE in all routines ; |
| 54 |
|
declare all the variables _RL ; use _d 0 for all numerical constants. |
| 55 |
|
use ifdef ALLOW_AIM everywhere. And now AIM can be used with g77 ! |
| 56 |
|
|
| 57 |
|
checkpoint46h_post |
| 58 |
|
o cleaned up the use of rhoNil and rhoConst. |
| 59 |
|
- rhoNil should only appear in the LINEAR equation of state, everywhere |
| 60 |
|
else rhoNil is replaced by rhoConst, e.g. find_rho computes rho-rhoConst |
| 61 |
|
and the dynamical equations are all divided by rhoConst |
| 62 |
|
o introduced new parameter rhoConstFresh, a reference density of fresh |
| 63 |
|
water, to remove the fresh water flux's dependence on rhoNil. The default |
| 64 |
|
value is 999.8 kg/m^3 |
| 65 |
|
o cleanup up external_forcing.F and external_forcing_surf.F |
| 66 |
|
- can now be used by both OCEANIC and OCEANICP |
| 67 |
|
checkpoint46h_pre |
| 68 |
|
|
| 69 |
|
Added code to convert surface volume flux (fresh water) into |
| 70 |
|
a mass flux when using P coordinates in the ocean (OCEANICP). |
| 71 |
|
Note: It assumes you have set rho0=rhoConst=density of fresh water. |
| 72 |
|
|
| 73 |
|
checkpoint46g_post |
| 74 |
|
o Include a new diagnostic variable phiHydLow for the ocean model |
| 75 |
|
- in z-coordinates, it is the bottom pressure anomaly |
| 76 |
|
- in p-coordinates, it is the sea surface elevation |
| 77 |
|
- in both cases, these variable have global drift, reflecting the mass |
| 78 |
|
drift in z-coordinates and the volume drift in p-coordinates |
| 79 |
|
- included time averaging for phiHydLow, be aware of the drift! |
| 80 |
|
o depth-dependent computation of Bo_surf for pressure coordinates |
| 81 |
|
in the ocean (buoyancyRelation='OCEANICP') |
| 82 |
|
- requires a new routine (FIND_RHO_SCALAR) to compute density with only |
| 83 |
|
Theta, Salinity, and Pressure in the parameter list. This routine is |
| 84 |
|
presently contained in find_rho.F. This routine does not give the |
| 85 |
|
correct density for 'POLY3', which would be a z-dependent reference |
| 86 |
|
density. |
| 87 |
|
o cleaned up find_rho |
| 88 |
|
- removed obsolete 'eqn' from the parameter list. |
| 89 |
|
o added two new verification experiments: gop and goz |
| 90 |
|
(4x4 degree global ocean, 15 layers in pressure and height coordinates) |
| 91 |
|
checkpoint46g_pre |
| 92 |
|
|
| 93 |
|
checkpoint46f_post |
| 94 |
|
o Enable tangent linear (forward mode) gradient checks: |
| 95 |
|
- extended active file handling to g_... files |
| 96 |
|
- added TANGENT_SIMULATION to theSimulationMode |
| 97 |
|
- extended grdchk package accordingly |
| 98 |
|
o added tangent linear setup in verification/carbon/code_ftl |
| 99 |
|
o added adjoint setup in verification/front_relax/code_ad |
| 100 |
|
|
| 101 |
|
checkpoint46e_post |
| 102 |
|
o Added new equation of state -> MDJWF |
| 103 |
|
- EOS of McDougall et al., 2002, JAOT, submitted |
| 104 |
|
- caveat: the equation of state is only valid for a smaller (more |
| 105 |
|
realistic?) range of values than JMD95P/Z and UNESCO |
| 106 |
|
- added masks to the calculation of pressure in store_pressure |
| 107 |
|
- added more check values for density in check_eos (ini_eos.F), some of |
| 108 |
|
the old check values are out of the range of the MDJWF-eos, so don't |
| 109 |
|
expect perfect matches for those |
| 110 |
|
checkpoint46e_pre |
| 111 |
|
|
| 112 |
|
checkpoint46d_post |
| 113 |
|
o fixed store_pressure to work with both buoyancy relation = 'OCEANIC' and |
| 114 |
|
'OCEANICP', also initialised field pressure correctly in ini_eos in the |
| 115 |
|
case of pressure coordinates. eosType='JMD95Z' in |
| 116 |
|
combination with buoyancyRelation='OCEANICP' now causes an error. |
| 117 |
|
o Changed p = pressure(i,j,k,bi,bj) to p = pressure(i,j,kRef,bi,bj) |
| 118 |
|
in find_alpha/beta. |
| 119 |
|
checkpoint46d_pre |
| 120 |
|
|
| 121 |
|
o Changed p = pressure(i,j,k,bi,bj) to p = pressure(i,j,kRef,bi,bj) |
| 122 |
|
so that JMD95Z and JMD95P give approptiate static stability in find_rho. |
| 123 |
|
|
| 124 |
|
checkpoint46c_post |
| 125 |
|
o Changes necessary for ocean in p-coordinates |
| 126 |
|
- Added new buoyancy relation = 'OCEANICP' |
| 127 |
|
- Added new parameters = gravitySign (this used to be contained inside |
| 128 |
|
the factor dRdZ which I added when we first switched to R coordinates). |
| 129 |
|
X GM/Redi is not compatible (yet) |
| 130 |
|
X bottom drag and no-slip need to be debugged. |
| 131 |
|
checkpoint46c_pre |
| 132 |
|
|
| 133 |
|
checkpoint46b_post |
| 134 |
|
o Added new equation of state -> JMD95Z and JMD95P |
| 135 |
|
- EOS of Jackett and McDougall, 1995, JAOT |
| 136 |
|
- moved all EOS parameters into EOS.h |
| 137 |
|
- new routines ini_eos.F, store_pressure.F |
| 138 |
|
o Added UNESCO EOS, but not recommended because it requires |
| 139 |
|
in-situ temperature (see JMD95) |
| 140 |
|
o Modified formatting for knudsen2.f in utils/knudsen2 and added |
| 141 |
|
unesco.f to be used with POLY3 |
| 142 |
|
checkpoint46b_pre |
| 143 |
|
|
| 144 |
|
checkpoint46a_post |
| 145 |
|
o Added (atmospheric) pressure loading |
| 146 |
|
- new field in FFIELDS.h, etc... |
| 147 |
|

| 148 |
|
o Changed hFacC to _hFacC in calc_phi_hyd.F |
| 149 |
|
o Added SHORTWAVE_HEATING to some files for consistency |
| 150 |
|
checkpoint46a_pre |
| 151 |

| 161 |
|
- modif's of existing cost functions |
| 162 |
|
o Adjoint-related bug fixes in kpp: |
| 163 |
|
- kpp_calc: sore of kpphbl avoids recomputation/call to S/R kppmix |
| 164 |
|
- kpp_routines: store of Rib avoids partial recomputation bug of TAF. |
| 165 |
|
o autodiff package |
| 166 |
|

| 194 |
|
o Removed f90 comments ("!") |

| 207 |
|
(TAF flow dependency) |
| 208 |
|
o in initialise_varia, moved call packages_init_variables |
| 209 |
|
before convective_adjustment_init |
| 210 |
|
(corresponding adjustment of TAF tape initialisation). |

|
o solve_for_pressure : set cg2d_x to zero where OBCS are applied |
| 218 |
|
|
| 219 |
|
checkpoint44h_post = checkpoint45 |
| 220 |
|
o Fix to restore differentiability: |
| 221 |
|
place at which packages_init_variables is called in |
| 222 |
|
initialise_varia is crucial for reverse control flow. |
| 223 |
|

(conflict on some platforms, e.g. IBM SP3) |
| 231 |
|
o modified carbon verif. |
| 232 |
|
|
| 233 |
|
checkpoint44h_pre |
| 234 |
|
o vertical grid option: allow to put the Interface at the middle between |
| 235 |
|
2 cell-centers ; replace delZ in pkg/kpp by drF. |
| 236 |
|
o GM Advective form: Tracers are advected using the residual transport (= |
| 237 |
|
Euler+GM-bolus); set param GM_AdvSeparate=T to return to previous form. |
| 238 |
|
|
| 239 |
|
checkpoint44g_post |
| 240 |
|
o fix surface correction term in multiDimAdvection (affects plume_on_slope |
| 241 |
|
results) ; ifdef missing in thermodynamics.F |
| 242 |
|
|
| 243 |
|
checkpoint44f_pre,checkpoint44f_post |
| 244 |
|
o added PTRACERS package |
| 245 |
|
This allows an arbitrary number of passive tracers to be integrated |
| 246 |
|
forward simultaneously with the dynamicaly model. |
| 247 |
|
+ Implemented so far: |
| 248 |
|
- basic forward algorithm (time-stepping, advection, diffusion, convection) |
| 249 |
|
- I/O and checkpointing |
| 250 |
|
- GM/Redi *but* using the GM/Redi coefficient of Salt |
| 251 |
|
+ Not implemented so far: |
| 252 |
|
- KPP |
| 253 |
|
- OBCS |
| 254 |
|
+ No specific example supplied (yet) but global_ocean.90x40x15 has the |
| 255 |
|
necessary data.ptracer file. Simply use -enable=ptracers and uncomment |
| 256 |
|
line in data.pkg. |
| 257 |
|
+ This package is disabled by default since it increases storage. |
| 258 |
|
|
| 259 |
|
|
| 260 |
|
o testscript: added -cleanup option |
| 261 |
