|
|
| 6 |
|
o staggerTimeStep & multi-Dim-Advec: Exch(U,V) added |
| 7 |
|
o staggerTimeStep & NLFS: rescale T & S surface tendencies. |
| 8 |
|
affects (truncation error) output of lab_sea & natl_box exp.: updated |
| 9 |
|
o change pickup _cd & _ptracers (old pickup restart: usePickupBeforeC54=.T.) |
| 10 |
|
|
| 11 |
|
checkpoint54a_post |
| 12 |
|
o re-write staggerTimeStep: step fwd U,V and then T,S (reverse the order). |
| 13 |
|
o change pickup file (to restart from old pickup, set usePickupBeforeC54=.T.) |
| 14 |
|
o get a perfect restart when using RealFreshWaterFlux + NLFS (not finished) |
| 15 |
|
o update output of all exp. that use staggerTimeStep (except hs94.cs & 2D) |
| 16 |
|
+ internal_wave (shift in writing cg2d_ini_res) |
| 17 |
|
checkpoint54a_pre |
| 18 |
|
|
| 19 |
|
o require forcing_In_AB=.FALSE. and remove surfaceTendencyTice from pkg/seaice |
| 20 |
|
- modified verification/lab_sea and natl_box_adjoint accordingly |
| 21 |
|
|
| 22 |
|
checkpoint54 |
| 23 |
|
checkpoint53g_post |
| 24 |
|
o prepare splitting of thermodynamics: store convect.counter in common block |
| 25 |
|
o store d.etaH/dt (instead of Div.hV) in common ; affects (truncation error) |
| 26 |
|
output of: global_ocean.cs32x15, global_ocean_pressure & internal_wave |
| 27 |
|
o cnh's modifs to gad_advection.F for cube-sphere multi-dim advection |
| 28 |
|
o new parameter "nShapS": allow to treat differently S from T (nShapT) |
| 29 |
|
o separate Vert.Advec.Scheme from horizontal Advec.Scheme (T & S) |
| 30 |
|
o restore adjointability |
| 31 |
|
|
| 32 |
|
checkpoint53f_post |
| 33 |
|
o modifications that affect AIM experiment results (update output.txt): |
| 34 |
|
- no advection of S at top interface Nr (pkg/generic_advdiff) |
| 35 |
|
- air surf. temp: use lower value between T0 & T1 (phy_suflux_prep.F) |
| 36 |
|
o AIM pkg: |
| 37 |
|
- include stability function into surf.Flux derivative relative to Tsurf |
| 38 |
|
- calculate clear-sky radiation & surface temp. change (for diagnostics) |
| 39 |
|
|
| 40 |
|
checkpoint53e_post |
| 41 |
|
o merged cylindrical coord configuration |
| 42 |
|
o added rotating_tank experiment |
| 43 |
|
checkpoint53e_pre |
| 44 |
|
|
| 45 |
|
checkpoint53d_post |
| 46 |
|
o faulks upgraded: re-generate output.txt that have changed: |
| 47 |
|
global_ocean.cs32x15(.thsice), global_ocean_ebm, lab_sea, natl_box |
| 48 |
|
o Added Bryan and Lewis, 1979, vertical diffusivity profile |
| 49 |
|
o pkg/land: fix problem in land_impl_temp.F when Ts arround freezing. |
| 50 |
|
o added Sadourny discretization of Coriolis |
| 51 |
|
- moved some PARAMETERS from mom_*_coriolis.F to PARAMS.h |
| 52 |
|
- re-enabled use of omega3 (useAbsVorticity) |
| 53 |
|
o added Leith (Phys. Fluids, 1968, 10, 1409-1416) variable viscosity for |
| 54 |
|
vector-invariant equations |
| 55 |
|
- note: does *NOT* yet use same variable visc. for no-slip BC's. |
| 56 |
|
o recoded the lateral boundary conditions for non-hydrostatic w, this time |
| 57 |
|
hopefully without new bugs |
| 58 |
|
- still to do: biharmonic friction for non-hydrostatic w |
| 59 |
|
o bug fix for mom_*_sidedrag: rA -> rAs,rAw |
| 60 |
|
o regenerated output for global_ocean_ebm (using -ieee) |
| 61 |
|
o fix mom_common/mom_*_sidedrag.F to recover numeric output prior to creation |
| 62 |
|
of mom_common/ |
| 63 |
|
- simple re-arrangement of instructions within computing loop |
| 64 |
|
checkpoint53d_pre |
| 65 |
|
|
| 66 |
|
checkpoint53c_post |
| 67 |
|
o new version of coupler for AIM+thSIce and Ocean models |
| 68 |
|
- new fields (SSS,h_MixLayer ...) are exchanged through the coupler |
| 69 |
|
- land: change Evaporation of snow |
| 70 |
|
- aim with thSIce: fix bug in snow-precip. |
| 71 |
|
o changes to calc_gw.F |
| 72 |
|
- bug fix for w^2 term near the bottom boundary |
| 73 |
|
- (hopefully) improve the lateral slip boundary condtions for use with |
| 74 |
|
partial/looped cells |
| 75 |
|
- because the bug fix changes two verification experiments anyway (exp5 |
| 76 |
|
and plume on slope), change the lateral boundary condition from half slip |
| 77 |
|
to the value of no_slip_sides |
| 78 |
|
o ebm package wasnt quite up to the parallel task. Fixed that. |
| 79 |
|
o Adjoint of EBM package + verification |
| 80 |
|
* TLM OK |
| 81 |
|
* ADM not sufficient accuracy yet (needs further testing) |
| 82 |
|
|
| 83 |
|
checkpoint53b_post |
| 84 |
|
o Commiting new energy balance model to repository |
| 85 |
|
* package is pkg/ebm |
| 86 |
|
* verif. is verification/global_ocean_ebm |
| 87 |
|
* references are in ebm_driver.F |
| 88 |
|
C * X. Wang, P. Stone and J. Marotzke, 1999: |
| 89 |
|

| 90 |
|
C Sensitivity to atmospheric moisture transport. |
| 91 |
|
C J. Climate 12(1), 71-82 |
| 92 |
|
C * X. Wang, P. Stone and J. Marotzke, 1999: |

| 99 |
|
C J. Climate 7(12), 1870-1882 |
| 100 |
|
o Will need long integration testing. |
| 101 |
|
checkpoint53b_pre |
| 102 |
|
|
| 103 |
|
o created pkg/mom_common in preparation for variable viscosity code |
| 104 |
|
o renamed and split ini_mnc_io |
| 105 |
|
o pkg/land: only liquid water can diffuse or run-off |
| 106 |
|
o AIM using land: soil wetness availability account for snow |
| 107 |
|
o added printMapIncludesZeros to EEPARMS namelist |
| 108 |
|
|
| 109 |
|
checkpoint53a_post |
| 110 |
|
o restore TAMC compatiility for exf_constants.h |
| 111 |
|
(no usage of _d in .h) |
| 112 |
|
o Additional storing in KPP in an attempt to fix |
| 113 |
|
TAMC problem with adjoint of KPP code. |
| 114 |
|
(no success...) |
| 115 |
|
Identical code works fine with TAF. |
| 116 |
|
o Fixed verification/natl_box_adjoint experiments. |
| 117 |
|
Initial conditions for Experiments 4 and 5 are now |
| 118 |
|
set to "SEAICE_initialHEFF=0", which is more reasonable, |
| 119 |
|
and hence gives results closer to that of Experiment 2. |
| 120 |
|
Experiment 6 requires "SEAICE_initialHEFF=1" and is working once again. |
| 121 |
|
|
| 122 |
|
checkpoint53 |
| 123 |
|
o stable checkpoint with up to date adjoint |
| 124 |
|
TLM tests only run for 1st grdchk at the moment. Its unclear if |
| 125 |
|
this is a code problem or a problem with resetting code for g_ |
| 126 |
|
variables that is being autogenerated wrong. |
| 127 |
|
Otherwise: |
| 128 |
|
o code is testing well on Linux (P4 and AMD), SGI Alitix and Irix. |
| 129 |
|
o IBM and HPQ tests could not be run because NCAR (IBM) and NCCS (HPQ) |
| 130 |
|
are both still in chaos following their security messes. |
| 131 |
|
|
| 132 |
|
checkpoint52n_post |
| 133 |
|
o various build (mostly genmake2) changes including: |
| 134 |
|
- ability to build/run more easily within Cygwin and MacOS X |
| 135 |
|
- more complicated Makefiles with a stronger dependence on Gnu Make |
| 136 |
|
o pkg/seaice modifications |
| 137 |
|
- added SEAICE_deltaTtherm and SEAICE_deltaTdyn in order to reduce cost |
| 138 |
|
of pkg/seaice. For time being, SEAICE_deltaTtherm = deltaTtracer |
| 139 |
|
and SEAICE_deltaTdyn must be integer multiple of SEAICE_deltaTtherm |
| 140 |
|
- changed proxy for geostrophic velocity and updated |
| 141 |
|
verification/lab_sea/results/* accordingly |
| 142 |
|
- removed ADI dynamic solver from pkg/seaice |
| 143 |
|
- replaced all occurrences of 1/CSTICE or 1/CSUICE |
| 144 |
|
they caused a segmentation fault under certain circumstances |
| 145 |
|
- removed unused field WATR |
| 146 |
|
o bug fix in exf-package: |
| 147 |
|
- u/vwind are defined at tracer/pressure points. The values of u/vwindmask |
| 148 |
|
now reflect that. |
| 149 |
|
o small fixes in the cal-package: |
| 150 |
|
- set reference date to first of January for the 'model'-calendar |
| 151 |
|
- failing of cal_CheckDate in cal_FullDate now actually results in a |
| 152 |
|
warning |
| 153 |
|
o small modifications in exf-package to increase flexibility: |
| 154 |
|
- change climtempfreeze from a constant to a runtime parameter that |
| 155 |
|
is specified in data.exf_clim (default = -1.9) |
| 156 |
|
- introduce runtime parameter windstressmax (default = 2.0) that is |
| 157 |
|
specified in data.exf |
| 158 |
|
o fix in pkg/thsice: |
| 159 |
|
- update Evap (Tsf changes) to be consistent with Latent heat flux |
| 160 |
|
- maintain snow precipitation unchanged (even if Tsf >=0). |
| 161 |
|
both affect global_ocean.cs32x15/(.thsice) results ; update output.txt.thsice |
| 162 |
|
|
| 163 |
|
checkpoint52m_post |
| 164 |
|
o commented out call to cal_GetMonthsRec in swfrac.F and added some comments; |
| 165 |
|
this does not change any of the results, because myIter=0 in swfrac always |
| 166 |
|
lead to jwtype=2 (the default anyway), but the call makes little sense |
| 167 |
|
as a default |
| 168 |
|
o no SHORTWAVE HEATING lost at the bottom; affects lab_sea output; updated |
| 169 |
|
o re-work pkg/thsice interface with ocean & bulk_force pkg to allow |
| 170 |
|
atmospheric model (AIM) to use it ; add a "slab ocean" component. |
| 171 |
|
o pkg/aim_v23 : add interface to call thermodynamic sea-ice (thsice) |
| 172 |
|
o update global_ocean.cs32x15/output (.thsice) after changes in pkg/thsice |
| 173 |
|
o extending useSingleCpuIO option to work with new exch2 I/O format |
| 174 |
|
- old-style, missing-tile I/O is still accessible by defining CPP |
| 175 |
|
option MISSING_TILE_IO in pkg/mdsio/MDSIO_OPTIONS.h |
| 176 |
|
o monitor package can write to NetCDF files and/or STDOUT |
| 177 |
|
o fix re-definition bug in MNC_GRID_INIT_ALL() |
| 178 |
|
o doc/api_reference added |
| 179 |
|
- a framework for building an API Reference Manual using all |
| 180 |
|
the "protex" comments embedded in the code |
| 181 |
|
- see pkg/generic_advdiff, pkg/mnc for examples |
| 182 |
|
o MNC: |
| 183 |
|
- make myThid the last argument for all subroutines |
| 184 |
|
- new default for the grid files: NO halos |
| 185 |
|
- add useMNC and other run-time flags |
| 186 |
|
- separate per-file-group handling of the unlimited dimension |
| 187 |
|
- early initialization of MNC w/ flags read at the eeboot stage |
| 188 |
|
and lookup tables set in initialize_fixed |
| 189 |
|
- write all MNC output to a freshly-created directory |
| 190 |
|
o thermodynamics sea-ice (thsice) is now tested with testreport. |
| 191 |
|
o test exp. advect_cs: use the standard cs32 grid ; update output. |
| 192 |
|
o Added functionality to grdchk: |
| 193 |
|
pick global i,j,k position (or nearest wet) where to perform check. |
| 194 |
|
|
| 195 |
|
checkpoint52l_post |
| 196 |
|
o new land formulation: |
| 197 |
|
a) use ground enthalpy as prognostic variable to ensure exact |
| 198 |
|
energy conservation. |
| 199 |
|
b) account for water temperature and for latent heat of freezing |
| 200 |
|
in all processes (rain, run-off, ground storage) |
| 201 |
|
c) compute surface and ground temperature implicitly. |
| 202 |
|
o aim_v23 modification for new land model: |
| 203 |
|
a) Treat separately land / ocean / sea-ice surface fluxes |
| 204 |
|
to allow implicit computation of land & sea-ice surface temp. |
| 205 |
|
b) add snow precipitation. |
| 206 |
