o model/src: modifications relatd to atmosphere p*: |
| 8 |
|
- Switch to more accurate p* coordinate slope term (calc_grad_phi_hyd.F) |
| 9 |
|
- With p* or Sigma-P, use constant reference Pot.Temp (thetaConst) instead |
| 10 |
|
of vertical profile tRef in geopotential background and anomaly. |
| 11 |
|
- Acount for true p* correction in theta <-> T conversion in pkg/aim_v23 |
| 12 |
|
and pkg/atm_phys. |
| 13 |
|
- Update FWD output of experiments: aim.5l_cs (x2), fizhi-cs-32x32x40, |
| 14 |
|
fizhi-cs-aqualev20, fizhi-gridalt-hs, tutorial_held_suarez_cs, cpl_aim+ocn. |
| 15 |
|
o pkg/seaice: fix a bug in seaice_prepare_ridging.F, forgot a sqrt |
| 16 |
|
o pkg/ptracers: compute ptracer source/sink due to linear free surface. |
| 17 |
|
not used right now, but can be used in BGC packages to fix conservation. |
| 18 |
|
o pkg/dic, pkg/gchem: move tracer_meanarea to gchem, so it can be used by |
| 19 |
|
other packages too. |
| 20 |
|
o pkg/seaice/seaice_calc_ice_strength.F: replace SEAICE_rhoSnow by |
| 21 |
|
SEAICE_rhoIce in the Rothrock (1975)-type strength calculations (bug fix) |
| 22 |
|
o model/src: |
| 23 |
|
- since we have several heat capacity (even in model/src), define "recip_Cp" |
| 24 |
|
as local variable (no longer in common block) to avoid any confusion. |
| 25 |
|
- add thetaConst in PARAMS.h (to be used with pStar or sigma-P coords). |
| 26 |
|
o pkg/exf: |
| 27 |
|
- from Jeff Scott: add option (#define EXF_CALC_ATMRHO) to calculate local |
| 28 |
|
air density as function of air Temp, Humidity and atm pressure. |
| 29 |

checkpoint64w (2014/05/02) |
| 31 |
|
o verification: |
| 32 |
|
- update output_adm.txt files for experiment global_ocean.cs32x15 (seaice & |
| 33 |
|
seaice_dynmix) and lab_sea (primary test & noseaicedyn): moving/changing |
| 34 |
|
code from seaice_growth.F & seaice_advdiff.F to new ridging routines |
| 35 |
|
seaice_reg_ridge.F seaice_do_ridging.F affects AD gradient |
| 36 |
|
(down to 8-7 matching digits for global_ocean and 5-6 for lab_sea). |
| 37 |
|
o model/src: for atmosphere in p* coords: |
| 38 |
|
- store factor rStarFacC**atm_kappa (= pStarFacK) in common block |
| 39 |
|
- implement more accurate p* coordinate slope term (in calc_grad_phi_hyd.F), |
| 40 |
|
but not yet activated. |
| 41 |
|
o pkg/seaice: fix restart problem for ITD with new ice strength parameterisation: |
| 42 |
|
- move computation of opnWtrFrac = 1-AREA to before computing ice strength |
| 43 |
|
- this changes the results (but not for any verification experiment, because |
| 44 |
|
none tests this), but avoids having an extra field in the restart files |
| 45 |
|
o pkg/seaice: remove global variable TICE (not needed) |
| 46 |
|
- replace by TICES or local variable where necessary (cost_seaice_test, |
| 47 |
|
seaice_diagnostics_state) |
| 48 |
|
- move copying TICE to TICES from seaice_check_pickup to seaice_read_pickup |
| 49 |
|
- use specific read/write routines for reading and writing individual leves |
| 50 |
|
of a multilevel field |
| 51 |
|
o pkg/ctrl & model/inc: |
| 52 |
|
- move additional anomaly fields of control vars (related to options: |
| 53 |
|
ALLOW_KAPGM_CONTROL, ALLOW_KAPREDI_CONTROL and ALLOW_BOTTOMDRAG_CONTROL) |
| 54 |
|
from DYNVARS.h into new header file: CTRL_FIELDS.h |
| 55 |
|
o pkg/seaice: some small modifications to the ridging code |
| 56 |
|
- make fw2ObyRidge a global variable and add the freshwater flux to |
| 57 |
|
seaice_growth |
| 58 |
|
- pass actual thickness from seaice_prepare_ridging, so that it is |
| 59 |
|
computed only in one place and compute it in the same way as in |
| 60 |
|
seaice_growth |
| 61 |
|
- initialise more fields in seaice_do_ridging that where cause floating |
| 62 |
|
point exceptions over land |
| 63 |
|
o pkg/seaice: preparations for ridging code and first real ridging code |
| 64 |
|
- move most of "PART 1" of S/R seaice_growth into a new and separate |
| 65 |
|
S/R seaice_reg_ridge that will both regularize the state variable after |
| 66 |
|
advection call the actual ridging routine; |
| 67 |
|
- requires to make 5 fields global fields: d_HEFFbyNEG,d_HSNWbyNEG, |
| 68 |
|
d_AREAbyRLX,d_HEFFbyRLX,saltFluxAdjust; |
| 69 |
|
- remove ridging code from seaice_advdiff |
| 70 |
|
- clean up remaining part 1 of seaice_growth in an attempt to make it |
| 71 |
|
more readable (this is probably subjective) |
| 72 |
|
- call seaice_itd_redist once in the initialisation phase to have the initial |
| 73 |
|
conditions in the correct category |
| 74 |
|
- finally: add new ridging routine for ITD code |
| 75 |
|
|
