|
o pkg/atm_phys: |
| 8 |
|
- allows to add some damping on uVel,vVel (strength only function of k). |
| 9 |
|
o verification, ad-tests: |
| 10 |
|
- reduce length of the simulation for AD test: global_ocean.cs32x15.seaice, |
| 11 |
|
global_ocean_ebm and offline_exf_seaice.thsice. |
| 12 |
|
o verification/halfpipe_streamice: |
| 13 |
|
- found a bug in s/r pkg/streamice/streamice_advect_thickness which caused |
| 14 |
|
flux input boundary conditions to be ignored; a fix for this bug changed |
| 15 |
|
verification results for forward test. |
| 16 |
|
- add adjoint test. |
| 17 |
|
o pkg/ptracers: |
| 18 |
|
- allow to restart without SOM pickup (resetting SOM to zero). |
| 19 |
|
o pkg/gmredi: |
| 20 |
|
- New parameterisation for the calculation of K and (GM_PsiX,GM_PsiY) added. |
| 21 |
|
- It uses mixing length theory and suppression by steering level effects to |
| 22 |
|
calculate a diffusivity used in the Redi tensor (see Bates et al., submitted |
| 23 |
|
to JPO, for more details). |
| 24 |
|
- It also uses the diffusivity to calculate an eddy induced streamfunction |
| 25 |
|
based on a PV closure (rather than a buoyancy closure as in GM). |
| 26 |
|
- New files added to pkg/gmredi: |
| 27 |
|
gmredi_k3d.F calculates the diffusivity for the Redi tensor and the eddy |
| 28 |
|
induced overturning streamfunction (called from gmredi_calc_tensor) |
| 29 |
|
gmredi_calc_eigs.F calculates the eigenvalues and eigenvectors required |
| 30 |
|
for use in gmredi_k3d |
| 31 |
|
gmredi_calc_urms.F calculates the the rms eddy velocity used to calculate |
| 32 |
|
the eddy diffusivity |
| 33 |
|
|
| 34 |
|
checkpoint64i (2013/06/18) |
| 35 |
|
o pkg/cheapaml: |
| 36 |
|
- take src files from MITgcm_contrib/verification_other/offline_cheapaml/code |
| 37 |
|
that enable the use of seaice (pkg/thsice thermo & pkg/seaice dynamics) |
| 38 |
|
with pkg/cheapaml. |
| 39 |
|
o utils/python: add subpackage for cubed sphere function, first example is |
| 40 |
|
simple cs.pcol to plot 2D fields on a map |
| 41 |
|
o pkg/streamice: |
| 42 |
|
- This is a new package in MITgcm, which solves dynamic equations for ice |
| 43 |
|
sheets and ice streams |
| 44 |
|
- At the moment it is independent of atmosphere/ocean dynamics, or any |
| 45 |
|
other physical packages in MITgcm, even ShelfIce (although it is anticipat- |
| 46 |
|
ed that this will change) |
| 47 |
|
- There is a new verification exercise that tests it, halfpipe_streamice, |
| 48 |
|
evolves a 40x80 km ice stream/ice shelf (at coarse resolution) in a |
| 49 |
|
rectangular embayment |
| 50 |
|
- halfpipe_streamice is forward-only for now, will have TAF test soon |
| 51 |
|
- for questions, email dgoldber@mit.edu |
| 52 |
|
o pkg/thsice: |
| 53 |
|
- fix filling of snow-precip diagnostic (SIsnwPrc) (left from the removing |
| 54 |
|
of snowPrc from common bloc, on May 2nd, thsice_step_fwd.F revision 1.40); |
| 55 |
|
- remove diagnostics 'SI_FrcFx' ( now identical to 'SI_Fract' with new |
| 56 |
|
call sequence: ice-Thermo(thsice),ice-Dyn,ice-Advect ); |
| 57 |
|
- allow precip from pkg/cheapaml to make snow over seaice. |
| 58 |
|
o pkg/cfc: |
| 59 |
|
- move in separated header file (CFC_ATMOS.h) time-serie arrays of Atmos CFC |
| 60 |
|
- remove atmos CFC 2-D arrays from common bloc (now local variables) |
| 61 |
|
- change some hard-coded constant to run time parameter for reading and |
| 62 |
|
and interpolating atmospheric CFC ; keep same default as previously. |
| 63 |
|
- more flexible reading of Atmos CFC (number of records no longer hard-coded) |
| 64 |
|
- put arguments in standard order: myTime, myIter, myThid |
| 65 |
|
- use standard S/R GET_PERIODIC_INTERVAL for time interpolation of |
| 66 |
|
atmospheric CFC ; fix for the case myIter < PTRACERS_iter0. |
| 67 |
|
- fix calculation of surf tendencys for partial-cell and/or Non-Lin Free-Surf |
| 68 |
|
- new routine to print summary of CFC params and check for consistency. |
| 69 |
|
o pkg/seaice: add uice/vice to the parameter list of s/r seaice_advdiff, |
| 70 |
|
similar to thsice_advdiff. |
| 71 |
|
Note that for the B-grid case the routine parameters uc/vc are overwritten. |
| 72 |
|
o pkg/cfc: |
| 73 |
|
- change time interpolation for atmospheric CFC-11 (now same as for CFC-12); |
| 74 |
|
update output (CFC-11) of experiment cfc_example and tutorial_cfc_offline. |
| 75 |
|
- fix interpolation of atmphspheric CFC between Sorthern and Northern |
| 76 |
|
hemisphere value. |
| 77 |
|
o pkg/seaice: |
| 78 |
|
- allow to use seaice dynamics without pkg/exf (e.g., using pkg/cheapaml) |
| 79 |
|
o pkg/seaice: add Adams-Bashforth2 time discretization for ice dynamics; |
| 80 |
|
so far only for JFNK-solver, turn on with SEAICEuseAB2 = .TRUE. |
| 81 |
|
- requires an additional time level that is stored in the pickup |
| 82 |
|
- you can start with AB2 from a pickup without this time level with |
| 83 |
|
pickupStrictlyMatch = .false. |
| 84 |
|
|
| 85 |
|
checkpoint64h (2013/05/26) |
| 86 |
|
o pkg/cheapaml: |
| 87 |
|
- replace one ()**.5 with SQRT + use temp var "cdu = tau/Du" (coare3_flux); |
| 88 |
|
affect machine truncation (but exp cheapAML_box still pass with 13 digits). |
| 89 |
|
- consistent treatment of uWind,vWind location: assume everywhere in |
| 90 |
|
pkg/cheapaml that they are on C-grid (@ uVel,vVel location) |
| 91 |
|
(Note: was already the case for Tair,Qair advection); |
| 92 |
|
add option (INCONSISTENT_WIND_LOCATION) to recover old results. |
| 93 |
|
- compute diabatic forcing only in the interior (excluding overlap regions) |
| 94 |
|
- fill in array "Qsw" (for short-wave heating); |
| 95 |
|
- add diagnostic for precip ; fill-in diagnostics for cheapAML state vars |
| 96 |
|
before any update (consistent with MITgcm state var diagnostics); |
| 97 |
|
- cheapaml_fields_load.F & cheapaml_init_varia.F : only fill outer edges if |
| 98 |
|
non periodic ; + adjusted for uWind,vWind (C-grid). |
| 99 |
|
o pkg/seaice: |
| 100 |
|
- remove dependence of pkg/seaice versus pkg/exf (file: pkg/pkg_depend) and |
| 101 |
|
add explicitly pkg/exf in experiments that currently use pkg/seaice. |
| 102 |
|
- allows to compile pkg/seaice without pkg/exf. |
| 103 |
|
o tools/OAD_support: |
| 104 |
|
- use a local copy (ourRWCPinBd) to ensure index ourRWCP stays within bounds |
| 105 |
|
of array "ourStepOf" in function rvNextAction (revolve.F90). |
| 106 |
|
o pkg/aim_compon_interf renamed to pkg/atm_compon_interf |
| 107 |
|
- change pkg name (to be used with other atmospheric physics pkg) |
| 108 |
|
but by-pass CVS when making the new pkg so that we keep the CVS history. |
| 109 |
|
o pkg/offline: |
| 110 |
|
- call OFFLINE_FIELDS_LOAD from pkg/offline/offline_init_varia.F |
| 111 |
|
(previously called from pkg/dic_surfforcing_init.F) |
| 112 |
|
o model/src: |
| 113 |
|
- re-order sequence of calls within packages_init_variables.F, using |
| 114 |
|
standard order, except for: |
| 115 |
|
DIAGNOSTICS_INIT_VARIA and OFFLINE_INIT_VARIA (called @ the top), |
| 116 |
|
CTRL_MAP_INI and OBCS_INIT_VARIABLES (called @ the bottom) |
| 117 |
|
o new pkg: atm_phys |
| 118 |
|
- add entry point and source code (previously in contrib |
| 119 |
|
verification_other/atm_gray/code_gray/) for new pkg "atm_phys" |
| 120 |
|
(atmospheric physics pkg from P. O'Gorman and T. Schneider, JCl, 2008). |
| 121 |
|
- re-order sequence of calls within packages_readparms.F, |
| 122 |
|
packages_init_fixed.F and packages_write_pickup.F |
| 123 |
|
(but skip packages_init_variables.F because of TAF issues). |
| 124 |
|
- update contrib/*/atm_gray/ experiment. |
| 125 |
|
o pkg/seaice (ITD code): |
| 126 |
|
- simplify and fix the writing of pickup-files for ITD case |
| 127 |
|
o pkg/seaice (ITD code): |
| 128 |
|
- introduce floe size dependent lateral melt for ITD case; |
| 129 |
|
- cleaning (avoid division by zero, change to f77 syntax, remove tabs) |
| 130 |
|
- update seaice_itd experiment main output. |
| 131 |
|
o pkg/thsice: |
| 132 |
|
- remove snowPrc from common block THSICE_FLUX, in THSICE_VARS.h and |
| 133 |
|
declared it locally (without bi,bj) in thsice_main.F & aim_do_physics.F; |
| 134 |
|
changed accordingly pkg/atm2d. |
| 135 |
|
|
| 136 |
|
checkpoint64g (2013/05/01) |
| 137 |
|
o pkg/exf ALLOW_RUNOFTEMP |
| 138 |
|
- if defined, river and glacier runoff temperature can be read-in from |
| 139 |
|
runoftempfile; runoftempfile needs to have same format as runofffile |
| 140 |
|
o pkg/thsice (& pkg/bulk_force): |
| 141 |
|
- In case Energy-Reference-Level (ERL) is used (temp_EvPrRn=0), account |
| 142 |
|
for energy content of Precip + RunOff & Evap (like with pkg/exf). |
| 143 |
|
- change computation domain to always be the interior (without overlap). |
| 144 |
|
- fix bug (wrong overlap) when using EXF and stressReduction > 0. |
| 145 |
|
o verification/tutorial_global_oce_biogeo: |
| 146 |
|
- add preliminary OpenAD setup (still has problems) |
| 147 |
|
o pkg/seaice: |
| 148 |
|
- turn some parameters for choosing the convergence criterion of |
| 149 |
|
the inexact Newton method (JFNK) into runtime parameters for convenience |
| 150 |
|
- clean up seaice_calc_viscosities.F: remove/retire two options for |
| 151 |
|
SEAICetaZmethod (1,2), introduce area weighting for method 3; this changes |
| 152 |
|
the results of lab_sea/input because a division has been replaced by |
| 153 |
|
a multiplication with the reciprocal (sumNorm) |
| 154 |
|
- modify offline_exf_seaice/input.dyn_jfnk/data.seaice to improve |
| 155 |
|
convergence of solver (changes results, of course), and to test some |
| 156 |
|
new features |
| 157 |
|
o model/src: |
| 158 |
|
- remove unused (since Aug 2006) S/R SET_WRITE_GLOBAL_PICKUP and its call. |
| 159 |
|
- remove unused forcing field "dQdT" and associated parameter "dQdTFile". |
| 160 |
|
- move forcing adjustment (balancing surface forcing) in specific S/R |
| 161 |
|
where might also be applied exchanges (if needed) to forcing arrays. |
| 162 |
|
o pkg/shelfice: |
| 163 |
|
- allow to specify the Ice-Shelf mass per unit area (instead of |
| 164 |
|
shelficeLoadAnomaly) and do the conversion from one to the other |
| 165 |
|
- move loading from file of shelficeLoadAnomaly from SHELFICE_INIT_VARIA |
| 166 |
|
to SHELFICE_INIT_FIXED: (a) avoid some TAF recompution issues and |
| 167 |
|
(b) will be loaded in time (before calling INI_PRESSURE) in case it is |
| 168 |
|
needed in phi0surf for initial pressure calculation when useDynP_inEos_Zc |
| 169 |
|
- update isomip experiment forward output (get machine truncation error |
| 170 |
|
from conversion shelficeLoadAnomaly -> shelficeMass -> shelficeLoadAnomaly) |
| 171 |
|
o verification/offline_exf_seaice: |
| 172 |
|
revise data.seaice in input.thermo and input_ad and update results accordingly |
| 173 |
|
HO = 0.2, SEAICE_areaLossFormula = 2, |
| 174 |
|
SEAICE_growMeltByConv = .TRUE., |
| 175 |
|
SEAICE_doOpenWaterMelt = .TRUE., |
| 176 |
|
Improve consistency with input.thsice and fix the spurious 500m ice corners |
| 177 |
|
o verification/global_ocean.cs32x15: |
| 178 |
|
- set Energy Reference Level to liq. water @ 0 degC: temp_EvPrRn=0., |
| 179 |
|
in icedyn (thsice+seaice-dyn) test and update output. |
| 180 |
|
o verification/offline_exf_seaice: |
| 181 |
|
- adjust list of tested variables (with testreport) and update |
| 182 |
|
standard test output with better slection of monitored fields. |
| 183 |
|
o pkg/cd_code: |
| 184 |
|
- swtich off Adams-Bashforth on the 1rst iteration. Update output of |
| 185 |
|
experiment lab_sea.hb87 |
| 186 |
|
o tools/genmake2: |
| 187 |
|
- change default makedepend from the system default to tools/xmakedepend: |
| 188 |
|
When no makedepend is specified, select tools/xmakedepend it the test pass, |
| 189 |
|
otherwise select the system default (if exist and pass the test) or |
| 190 |
|
try to build cyrus-makedepend ; stop if none of the 3 works. |
| 191 |
|
o pkg/exf & pkg/thsice: |
| 192 |
|
- In case Energy-Reference-Level (ERL) is used (temp_EvPrRn=0), account |
| 193 |
|
for energy content of Precip + RunOff & Evap. Assumes: |
| 194 |
|
1) Rain has same temp as Air. |
| 195 |
|
2) Snow has no heat capacity (consistent with seaice & thsice pkgs) |
| 196 |
|
3) Run-Off comes at the temp of surface water (with same Cp) |
| 197 |
|
4) Evap over ocean is released to the Atmos @ surf-temp (=SST); should be |
| 198 |
|
put directly into Latent Heat flux & should use water-vapor heat capacity. |
| 199 |
|
5) Evap over snow/seaice (pkg/thsice) assumes constant Lf+Lv (consistent |
| 200 |
|
with snow having no Cp) => water vapor is released to Atmos @ 0^oC (=ERL). |
| 201 |
o pkg/seaice: simplify the use of CPP flags in JFNK-related files |
o pkg/seaice: simplify the use of CPP flags in JFNK-related files |
| 202 |
(compile when SEAICE_ALLOW_JFNK is defined) |
(compile when SEAICE_ALLOW_JFNK is defined) |
