3      Notes on tags used in MITgcmUV      Notes on tags used in MITgcmUV
4      ==============================      ==============================
5    
6    o removed gravitySign from PARM04
7    o switched to g77/ifc from pgf77 in aim experiments
8    
9    checkpoint46l_post
10    o made convective adjustment work with pressure coordinates:
11     - changed the direction of k-loop in convective_adjustment.F for the
12       case of pressure coordinates (OCEANICP,ATMOSPHERIC buoyancyRelation)
13     - adjusted the reference pressure k-index in convective_adjustment.F
14     - adjusted the convection condition in convect.F (in analogy to
15       calc_ivdc.F)
16     - convective_adjustment no longer computes anything on the halos
17     - removed the warnings about negative salinity from find_rho.F and
18       find_alpha.F; instead the new routine look_for_neg_salinity, called
19       at the beginning of find_rho, find_alpha, and find_beta, does a
20       check of the entire slice, if CPP-option
21       CHECK_SALINITY_FOR_NEGATIVE_VALUES is defined
22    checkpoint46l_pre
23    
24    checkpoint46k_post
25    o fixed the verification/global_ocean.90x40x15 experiment:
26     - new bathymetry (the world according to A., JMC, and M.)
27     - new initial fields and forcing fields (*.bin files)
28     - new POLY3.COEFFS (for the next release one should switch to a full
29       equation of state: JMD95P or MDJWF)
30     - fixed several errors and redundancies in the data file
31     - experiment uses looped cells
32     - added matlab directory with diagnostic scripts for plotting of output
33    
34    o S/R aim_initialise.F replace S/R aim_init from file aim_do_inphys.F:
35     - read AIM physics parameters from a file (data.aimphys)
36     - set defaults values = F.Molteni paper (Clim.Dyn., 2002)
37    
38    checkpoint46j_post
39    o split calc_exact_eta in 2 S/R : integr_continuity & update_etaH
40    o move wVel computation at the end of the time step, in S/R integr_continuity
41    o create specific S/R to exchange T,S before DYNAMICS (for stagger time step)
42    o update timeave pkg for wVel diagnostic.
43    checkpoint46j_pre
44    
45    checkpoint46i_post
46    o Clean up AIM package (and keep the results unchanged):
47      include CPP_OPTION and use IMPLICT NONE in all routines ;
48      declare all the variables _RL ; use _d 0 for all numerical constants.
49      use ifdef ALLOW_AIM everywhere. And now AIM can be used with g77 !
50    
51    checkpoint46h_post
52    o cleaned up the use of rhoNil and rhoConst.
53      - rhoNil should only appear in the LINEAR equation of state, everywhere
54        else rhoNil is replaced by rhoConst, e.g. find_rho computes rho-rhoConst
55        and the dynamical equations are all divided by rhoConst
56    o introduced new parameter rhoConstFresh, a reference density of fresh
57      water, to remove the fresh water flux's dependence on rhoNil. The default
58      value is 999.8 kg/m^3
59    o cleanup up external_forcing.F and external_forcing_surf.F
60      - can now be used by both OCEANIC and OCEANICP
61    checkpoint46h_pre
62    
63     Added code to convert surface volume flux (fresh water) into
64     a mass flux when using P coordinates in the ocean (OCEANICP).
65     Note: It assumes you have set rho0=rhoConst=density of fresh water.
66    
67  checkpoint46g_post  checkpoint46g_post
68  o Include a new diagnostic variable phiHydLow for the ocean model  o Include a new diagnostic variable phiHydLow for the ocean model
69    - in z-coordinates, it is the bottom pressure anomaly    - in z-coordinates, it is the bottom pressure anomaly
