4      ==============================      ==============================
5    
6    checkpoint48h_post
7    o improve "ini_p_ground" when using finite difference form for calc_phi_hyd
8    o Added net flux to downward flux conversion to pkg/exf/exf_getffields.F
9    o Added SEAICE_initialHEFF to pkg/seaice
10    o ecco_the_model_main.F: SEAICE_WRITE_PICKUP must precede WRITE_CHECKPOINT
11    
12    checkpoint48g_post
13    --- EOS:
14    o compute locally the pressure for use in EOS: UNESCO, JMD95P, MDJWF
15      store total Potential in totPhyHyd for diagnostics & EOS.
16    o fix restart and overlap Pb when using Z-coord and EOS funct. of P
17    --- Pressure/geopotential gradient:
18    o use Ro_surf & R_low instead of hFac in cal_phi_hyd:
19    o NLFS + p-coord.: eta*Alpha' is not longer lagging 1.time-step behind
20      ( changes results of global_ocean_pressure )
21    o NLFS + z-coord.: add eta*Rho' contribution.
22    o accurate phiHyd when using interface-W at the middle between 2 centers
23     ( changes results of ideal_2D_oce )
24    o includes r* 2nd term in potential gradient.
25    
26    checkpoint48f_post
27    Merging from release1_p12:
28    o Modifications for using pkg/exf with pkg/seaice
29      - improved description of the various forcing configurations
30      - added basic radiation bulk formulae to pkg/exf
31      - units/sign fix for evap computation in exf_getffields.F
32      - updated verification/global_with_exf/results/output.txt
33    o Added pkg/sbo for computing IERS Special Bureau for the Oceans
34      (SBO) core products, including oceanic mass, center-of-mass,
35      angular, and bottom pressure (see pkg/sbo/README.sbo).
36    o Lower bound for viscosity/diffusivity in pkg/kpp/kpp_routines.F
37      to avoid negative values in shallow regions.
38      - updated verification/natl_box/results/output.txt
39      - updated verification/lab_sea/results/output.txt
40    o MPI gather, scatter: eesupp/src/gather_2d.F and scatter_2d.F
41    o Added useSingleCpuIO option (see PARAMS.h).
42    o Updated useSingleCpuIO option in mdsio_writefield.F to
43      work with multi-field files, e.g., for single-file pickup.
44    o pkg/seaice:
45      - bug fix in growth.F: QNET for no shortwave case
46      - added HeffFile for specifying initial sea-ice thickness
47      - changed SEAICE_EXTERNAL_FLUXES wind stress implementation
48    o Added missing /* */ to CPP comments in pkg/seaice, pkg/exf,
49      kpp_transport_t.F, forward_step.F, and the_main_loop.F
50    o pkg/seaice:
51      - adjoint-friendly modifications
52      - added a SEAICE_WRITE_PICKUP at end of the_model_main.F
53    
54    checkpoint48e_post
55    o New S/R for diagnostic of bottom pressure (phi0surf was missing in c48d_post)
56    o dynamics: change definition of computational domain & adapt mom_fluxform
57      accordingly ; when viscA4=0, allows to run the dynamics with Olx=Oly=2.
58    o following exp works with Olx=Oly=2 (and pass through checkbounds option):
59        adjust_nlfs.cs-32x32x1 adjustment.128x64x1 adjustment.cs-32x32x1
60        exp0 exp1 exp2 exp4 exp5 hs94.cs-32x32x5 hs94.128x64x5 hs94.1x64x5
61        global_ocean.90x40x15 global_with_exf global_ocean_pressure
62        inverted_barometer solid-body.cs-32x32x1
63      (high order AdvScheme and/or multiDimAd works with Olx=Oly=2 ? not sure)
64    
65    checkpoint48d_post
66    o in preparation for r*:
67     a) use pre-computed gradient of hydrostatic potential:
68        changes in timestep.F & mom_cdscheme.F affects results of ideal_2D_oce
69     b) move phi0surf from calc_phi_hyd to calc_grad_phi_hyd:
70        => affects results of glob_oce_pressure (different truncation error)  
71      update output.txt of ideal_2D_oce & global_ocean_pressure
72    
73    checkpoint48d_pre
74    o in preparation for r*:
75      new S/R (calc_grad_phi_hyd.F) to compute Hydrostatic potential gradient.
76      pass the 2 comp. of the grad. as arguments to momentum S/R.
77      but for the moment, only used if it does not change the results.
78    o add finite volume form of calc_phi_hyd for buoyancyRelation OCEANIC & OCEANICP
79    
80    checkpoint48c_post
81    Modifications in treatment of initial flux forcing controls
82    to avoid extra storing of flux fields.
83    
84    checkpoint48c_pre
85    o Added tidal_basin_2d experiment (currently 1D!)
86    o can use r* Coordinate with OBC (but Orlanski Rad. BC not yet implemented)
87    
88    checkpoint48b_post
89    o r* coordinate added in #ifdef NONLIN_FRSURF block.
90     (modification to pressure gradient not yet implemented)
91    o mom_fluxform: new S/R mom_calc_rtrans.F computes vertical transports
92      (for U & V) that are used for vertical advection of momentum.
93    
94    checkpoint48a_post
95    o In preparation for r*, use temp. array to compute vertical transport
96       in flux-form momentum pkg. => change results of few test-exp.
97      Update output of: exp4, exp5, front_relax, global_ocean_pressure,
98                        lab_sea, natl_box & plume_on_slope
99    
100  checkpoint48  checkpoint48
101  o fix small bug that was causing lot of warning (TIMER_STOP 'UPDATE_CG2D')  o fix small bug that was causing lot of warning (TIMER_STOP 'UPDATE_CG2D')
