checkpoint44f_pre,checkpoint44f_post |
| 7 |
|
o added PTRACERS package |
| 8 |
|
This allows an arbitrary number of passive tracers to be integrated |
| 9 |
|
forward simultaneously with the dynamicaly model. |
| 10 |
|
+ Implemented so far: |
| 11 |
|
- basic forward algorithm (time-stepping, advection, diffusion, convection) |
| 12 |
|
- I/O and checkpointing |
| 13 |
|
- GM/Redi *but* using the GM/Redi coefficient of Salt |
| 14 |
|
+ Not implemented so far: |
| 15 |
|
- KPP |
| 16 |
|
- OBCS |
| 17 |
|
+ No specific example supplied (yet) but global_ocean.90x40x15 has the |
| 18 |
|
necessary data.ptracer file. Simply use -enable=ptracers and uncomment |
| 19 |
|
line in data.pkg. |
| 20 |
|
+ This package is disabled by default since it increases storage. |
| 21 |
|
|
| 22 |
|
|
| 23 |
|
o testscript: added -cleanup option |
| 24 |
|
o Shap_filt: a) new shap_filt S/R to use no-slip BC with S2 filter |
| 25 |
|
b) enable to filter 2D fields. |
| 26 |
|
|
| 27 |
|
checkpoint44e_pre,post |
| 28 |
|
o re-wrote convective adjustment to use pre-calculated weights |
| 29 |
|
Affects: model/src/convective_adjustment.F, convective_adjustment_ini.F |
| 30 |
|
Adds: model/src/convective_weights.F, convectively_mixtracer.F |
| 31 |
|
Original calls to convect() still in place. |
| 32 |
|
|
| 33 |
|
chkpt44d_pre,post |
| 34 |
|
o added missing EXCLUDE_MONITOR flags |
| 35 |
|
o changed "e" to "_d" in gmredi_slope_limit, gmredi_slope_psi |
| 36 |
|
(incompatible typ in MIN/MAX expressions caused problems |
| 37 |
|
on IBM SP3) |
| 38 |
|
o in genmake added variable MAKEDEPEND |
| 39 |
|
plus resetting for case SunOS |
| 40 |
|
o added timer_stats.c routine for IBM SP3 |
| 41 |
|
o removed variables in dynamics |
| 42 |
|
!!! I forgot to create tag chkpt44d_pre !!! |
| 43 |
|
!!! But chkpt44d_pre = chkpt44c_post !!! |
| 44 |
|
|
| 45 |
|
o real fresh water flux implemented with non-linear free-surface. |
| 46 |
|
|
| 47 |
|
chkpt44c_pre,post |
| 48 |
|
o few fix (mask in shap_s2, EmPmR in external_field_load, |
| 49 |
|
USE_NATURAL_BCS in solve_for_P); |
| 50 |
|
o add arguments myIter & myTime to S/R obcs_calc & solve_for_P |
| 51 |
|
|
| 52 |
|
checkpoint44b_pre/_post |

|
|
| 64 |
|
o check parameters & config (chkpt44a_pre,post) |

| 84 |
|

| 90 |
|
for the case ALLOW_KPP |
| 91 |

| 95 |
|
to work with protex |
| 96 |
|
|
| 97 |
|
checkpoint40 |
| 98 |
|
o moved calc_gs, calc_gt and calc_tr1 back to model/src |
| 99 |
|
o added FLT (floats) package from Arne along with demo. experiment |
| 100 |
|
o re-arranged Adams-Bashforth scheme for tracers to allow easier |
| 101 |
|
implementation of forward-in-time forcing terms |
| 102 |

|
|
| 116 |
|
checkpoint40pre8 |
| 117 |
|
o new package rw/ |
| 118 |
|
Added method for dumping intermediate local arrays: |
| 119 |
|
mdsio_writetile - same as mdsio_writefield except works from inside |
| 120 |
|
bi,bj loop |
| 121 |
|
mdsio_writelocal - same as mdsio_writetile except works for local |
| 122 |
|
arrays |
| 123 |
|
write_local_r? - higher-level wrapper for mdsio_writelocal |
| 124 |
|
Controlled by diagFreq. Defaults to zero (ie. no dumps) |
| 125 |
|
Example given at end of mom_vecinv.F that dumps some local arrays. |
| 126 |
|
o replaced calc_mom_rhs.F by mom_fluxform.F/mom_vecinc.F to |
| 127 |
|
control flux-form versus vector invariant code. |
| 128 |
|
Switch is runtime flag vectorInvariantMomentum (defaults to false) |
| 129 |
|
or genmake -DISABLE ... |
| 130 |
|
o TAMC-related update to cope with mom_fluxform.F/mom_vecinc.F |
| 131 |
|
(additional storing is now needed for case vecinv; |
| 132 |
|
currently nothing implemented to switch this storing off |
| 133 |
|
in case fluxform is used since no CPP flag available). |
| 134 |
|
|
| 135 |
|
checkpoint40pre7 |
| 136 |
|
o bug fix in dynamics.F |
| 137 |

| 140 |
|
related to TAF |
| 141 |
|
|
| 142 |
|
checkpoint40pre6 |
| 143 |
|
o split dynamics into thermodynamics & dynamics |
| 144 |
|
o corresponding split of calc_diffusivity into |
| 145 |
|
calc_diffusivity, calc_viscosity |
| 146 |
|
(kpp_calc_diff, kpp_calc_visc). |
| 147 |
|
o Added diffkr, kapgm to control variables |
| 148 |
|
o bug fix in gmredi_slope_limit for ldd97 |
| 149 |
|
|
| 150 |
|
checkpoint40pre5 |
| 151 |
|
o proper initialization of Adams-Bashforth time stepping |
| 152 |
|
+ uses forward step for very first step of model (iter=0) |
| 153 |
|
o re-generated *all* output since almost all output is modified by this |
| 154 |
|
change (sorry but we've been putting this one off for about 2 years) |
| 155 |
|
+ natl_box, aim.5l_Equatorial_Channel and aim.5l_zon-ave were |
| 156 |
|
*not* regenerated since they are already out of date and I don't |
| 157 |
|
want to create the impression that they are suddenly working. |
| 158 |
|
o removed KAP stuff for DEC's |
| 159 |
|
o modified/added many .cvsignore files in */code and */input |
| 160 |
|
o added new expt "solid-body.cs-32x32x1" |
| 161 |
|
+ this uses an alternative form of ini_curvilinear_grid.F which |
| 162 |
|
is not necessarily any better than the current one... |
| 163 |
|
|
| 164 |
|
checkpoint40pre4 |
| 165 |
|
o added re-initialisations of utrans,vtrans,rtrans in |
| 166 |
|
calc_common_factors which are crucial for TAF. |
| 167 |
|
o extended iMin,jMin range for calc_common_factors, |
| 168 |
|
calc_diffusivity |
| 169 |
|
o added option ALLOW_PASSIVE_TRACER |
| 170 |
|
o a few minor updates and fixes |
| 171 |
|
|
| 172 |
|
checkpoint40pre3 |
| 173 |
|
o created calc_gtr1.F for gad package |
| 174 |
|
o split the_main_loop and re-introduced forward_step |
| 175 |
|

| 176 |
|
|
| 177 |
|

checkpoint39 |
| 184 |
|

| 185 |
|
(mainly missing or wrong directives) |
| 186 |
|
o Corrected common blocks when fooling TAMC to produce adjoint I/O |
| 187 |
|
in addummy_in_stepping |
| 188 |
|

| 189 |
|
o Enabled "sliced" (xz-,yz-) exchanges, needed for obcs. |
| 190 |
|
o Included following packages: |
| 191 |
|
cal: calendar |
| 192 |
|
exf: external forcing |
| 193 |
|
ecco: essential routines to control use of cal, exf |
| 194 |
|
(NB: this is not the full ECCO environment) |
| 195 |
|
o disabled some packages by default in genmake |
| 196 |
|
|
| 197 |
|
checkpoint38 |
| 198 |
|
o see notes_c37_adj.txt |
| 199 |
|
o corrected wrong layer index in external_forcing_t |
| 200 |
|
o replaced the_main_loop/forward_step by the_main_loop |
| 201 |
|
o removed forceoutput from write_state |
| 202 |
|
(replaced criteria for initial/final state) |
| 203 |
|
o added runtime flag for pre-C35 pickups: usePickupBeforeC35 |
| 204 |
|
|
| 205 |
|
checkpoint37 |
| 206 |
|
o mdsio.F routine split and packaged in pkg/mdsio |
| 207 |
|
(mdsio.F and mdsio_gl.F still exist in eesupp/src but are not |
| 208 |
|
used unless genmake -disable=mdsio) |
| 209 |
|
o allow a more precise surface-geopotential gradient for the atmosphere |
| 210 |
|
taking into account the change in space of Alpha (=1/rho) at the surface. |
| 211 |
|
o variable "etaN" (replace cg2d_x) is the surface R-anomaly [r unit] |
| 212 |
|
(ocean: sea surface height [m] / atmos: surface pressure anomaly [Pa]) |
| 213 |
|
o Change units: Phi_Hydrostatic (=phiHyd), Phi_Surface(=cg2d_x) and |
| 214 |
|
Phi_NonHydrostatic (=cg3d_x), all have now the dimension of a potential |
| 215 |
|
[m2/s2] (pressure/rhoConst in the ocean ; Geo-Potential in the atmosphere). |
| 216 |
|
o Time-Average diagnostics defined as a pseudo package "timeave". |
| 217 |
|
o pickup files : old pickup (before c35) did not work with new code (c35 |
| 218 |
|
and after) unless activating 2 commented lines in initialise-varia. |
| 219 |
|
o Non-Hydrostatic pickup file Pb fixed. |
| 220 |
|

| 226 |
|
o AIM become a standard package ; clean unused CPP_kees |
| 227 |
|
|
| 228 |
checkpoint35 |
checkpoint35 |
| 229 |
o subtantial rewrite of dynamics.f |
o subtantial rewrite of dynamics.f |
| 230 |
o allows staggered time-stepping |
