|
o seaice: add an EVP solver following Hunke and Dukowicz (1997) and the |
| 8 |
|
documentation of CICE. Turn on by defining SEAICE_ALLOW_EVP in |
| 9 |
|
SEAICE_OPTIONS.h and SEAICEuseEVP=.true. in data.seaice. Works only |
| 10 |
|
with SEAICE_CGRID defined. |
| 11 |
|
o move calendarDumps from "data" to "data.cal" and clean-up the code |
| 12 |
|
with a simple call to pkg/cal S/R: CAL_TIME2WRITE |
| 13 |
|
o add useEXF & useCAL flags (for now, set in hard-coded way) |
| 14 |
|
o add S/R to compute NH-metrics terms & Coriolis f' in vertical momentum |
| 15 |
|
(were missing in NH mode, and wrong in quasihydrostatic mode). |
| 16 |
|
waiting for Chris updated version of calc_gw to add those CALLs. |
| 17 |
|
o fix bug in quasihydrostatic S/R ; |
| 18 |
|
add a test for this option: global_ocean.90x40x15.qshyd |
| 19 |
|
o new S/R "SET_PARMS": set parameters that might depend on the use of some pkgs. |
| 20 |
|
(called from INITIALISE_FIXED, after INI_PARMS & PACKAGES_READPARAMS) |
| 21 |
|
o add on/off flag useOffLine for package OFFLINE |
| 22 |
|
o seaice: |
| 23 |
|
- modify advection so that it works also on the C-grid |
| 24 |
|
- extend loop ranges in seaice_lsr and seaice_dynsolver; fixes |
| 25 |
|
problem in multi-tile runs with C-grid |
| 26 |
|
- add flags for clipping ice velocities and/or masking solver forcing |
| 27 |
|
- fix drag (ocean on ice) formulation and a bug that caused noise in the |
| 28 |
|
C-grid solver |
| 29 |
|
- added a few comments to seaice_diffusion.F |
| 30 |
|
- separate C-grid and B-grid versions more cleanly (UVM and seaiceMaskU/V |
| 31 |
|
are now exclusive) |
| 32 |
|
- add a new ocean-ice stress coupling method (Hibler and Bryan, 1987) which |
| 33 |
|
required re-ordering the code a little: |
| 34 |
|
+ make DAIRN global variable (defined in SEAICE) |
| 35 |
|
+ move computation of the viscosities eta and zeta into a new separate |
| 36 |
|
routine (because I need to recompute them in seaice_ocean_stress.F) |
| 37 |
|
|
| 38 |
|
checkpoint58b_post |
| 39 |
|
o AIM+thSIce: fix sign of Short-Wave through the Ice ; |
| 40 |
|
update output.txt of exp. aim.5l_cs.thSI |
| 41 |
|
o various mnc cleanups and improvements: |
| 42 |
|
+ shrink lookup tables by factor of ~4 |
| 43 |
|
+ better error reporting when running out of lookup space |
| 44 |
|
+ able to handle longer path/file names (up to 500 chars) |
| 45 |
|
o adjoint: |
| 46 |
|
- Another overhaul of store dirs. for NLFS to eliminate "hidden" recomputations. |
| 47 |
|
- TBD: "hidden" mom_vecinv recomp. in dynamics |
| 48 |
|
o change forcing_In_AB to affects both T,S forcing and Momentum forcing |
| 49 |
|
(allow to differentiate between forcing components using new integer flags: |
| 50 |
|
momForcingOutAB=1/0 & tracForcingOutAB=1/0) |
| 51 |
|
and add new flag to put Dissipation tendency out of Adams-Bashforth. |
| 52 |
|
o ecco |
| 53 |
|
- enable trend removal from SSH anomaly obs. |
| 54 |
|
o adjoint |
| 55 |
|
- a fix for PmEpR when #undef EXACT_CONSERV |
| 56 |
|
- fix of "hidden" recomp. in thermodynamics (no TAF warnings) |
| 57 |
|
- try to fix "hidden" recomp. in forward_step for NLFS |
| 58 |
|
(NLFS seems broken sometimes after I checked it in) |
| 59 |
|
o seaice: |
| 60 |
|
- add c-grid version of the dynamic solver: |
| 61 |
|
+ three new routines that are the c-grid substitute lsr, dynsolver |
| 62 |
|
and ostres |
| 63 |
|
+ put a few fields that were local to dynsolver into global common |
| 64 |
|
blocks, so that I can move the computation of stresses etc into |
| 65 |
|
seaice_lsr (saves coding but may break the adjoint). |
| 66 |
|
- replace more hardwired parameters by runtime parameters |
| 67 |
|
- add ice masks that mask the rhs of the implicit solvers where there |
| 68 |
|
is no ice (commented out in seaice_dynsolver, because i am not sure |
| 69 |
|
if this works properly), eventually this should replace the clipping |
| 70 |
|
of ice velocities in seaice_dynsolver to +/-40cm/s. |
| 71 |
|
o remove the BUILD_INFO.h include from CPP_EEOPTIONS.h and explicitly |
| 72 |
|
include it only where its needed |
| 73 |
|
o move balancing of fluxes before the call of external_forcing_surf |
| 74 |
|
o seaice: |
| 75 |
|
- correct units of turning angles (now they are really in degrees) |
| 76 |
|
- move computation of GWATX/Y out of main routine into dynsolver |
| 77 |
|
- initialize GWATX/Y in seaice_init |
| 78 |
|
o Apply mask on Fresh-Water flux (needed for SSH forcing). |
| 79 |
|
update output.txt of exp. global_ocean_ebm & cpl_aim+ocn (affects cg2d residual) |
| 80 |
|
o seaice: add runtime flags for turning angles (default to zero) |
| 81 |
|
o Adding runtime parameter to exf/, ctrl/, to remove on-the-fly global mean |
| 82 |
|
and trend from exf forcing and ctrl control adjustments |
| 83 |
|
o fix variable aliasing in gad_calc_rhs that cannot be handled by TAF |
| 84 |
|
(since checkpoint57x_post) |
| 85 |
|
o change the default rotation period to 86164.s = the Earth rotation |
| 86 |
|
o 1rst implementation of Implicit IGW using the 3-D solver (use3Dsolver=T) |
| 87 |
|
and based on a reference stratification. Tested within hs94.cs-32x32x5. |
| 88 |
o seaice advection: add code for choosing between the default (2nd order |
