5      ==============================      ==============================
6    
7    o adjoint:
8      - Another overhaul of store dirs. for NLFS to eliminate  "hidden" recomputations.
9      - TBD: "hidden" mom_vecinv recomp. in dynamics
10    o change forcing_In_AB to affects both T,S forcing and Momentum forcing
11     (allow to differentiate between forcing components using new integer flags:
12      momForcingOutAB=1/0 & tracForcingOutAB=1/0)
13     and add new flag to put Dissipation tendency out of Adams-Bashforth.
14    o ecco
15      - enable trend removal from SSH anomaly obs.
16    o adjoint
17      - a fix for PmEpR when #undef EXACT_CONSERV
18      - fix of "hidden" recomp. in thermodynamics (no TAF warnings)
19      - try to fix "hidden" recomp. in forward_step for NLFS
20        (NLFS seems broken sometimes after I checked it in)
21    o seaice:
22     - add c-grid version of the dynamic solver:
23       + three new routines that are the c-grid substitute lsr, dynsolver
24         and ostres
25       + put a few fields that were local to dynsolver into global common
26         blocks, so that I can move the computation of stresses etc into
27         seaice_lsr (saves coding but may break the adjoint).
28     - replace more hardwired parameters by runtime parameters
29     - add ice masks that mask the rhs of the implicit solvers where there
30       is no ice (commented out in seaice_dynsolver, because i am not sure
31       if this works properly), eventually this should replace the clipping
32       of ice velocities in seaice_dynsolver to +/-40cm/s.
33    o remove the BUILD_INFO.h include from CPP_EEOPTIONS.h and explicitly
34      include it only where its needed
35    o move balancing of fluxes before the call of external_forcing_surf
36    o seaice:
37      - correct units of turning angles (now they are really in degrees)
38      - move computation of GWATX/Y out of main routine into dynsolver
39      - initialize GWATX/Y in seaice_init
40    o Apply mask on Fresh-Water flux (needed for SSH forcing).
41      update output.txt of exp. global_ocean_ebm & cpl_aim+ocn (affects cg2d residual)
42    o seaice: add runtime flags for turning angles (default to zero)
43    o Adding runtime parameter to exf/, ctrl/, to remove on-the-fly global mean
44      and trend from exf forcing and ctrl control adjustments
45    o fix variable aliasing in gad_calc_rhs that cannot be handled by TAF
46      (since checkpoint57x_post)
47    o change the default rotation period to 86164.s = the Earth rotation
48    o 1rst implementation of Implicit IGW using the 3-D solver (use3Dsolver=T)
49      and based on a reference stratification. Tested within hs94.cs-32x32x5.
50    o seaice advection: add code for choosing between the default (2nd order
51      central differences) and multiDim advection schemes provided by
52      pkg/generic_advdiff
53    o seaice:
54      - removed all references to SEAICE_GRID.h fields from
55        dynsolver, advect, diffus, lsr, without changing the results of lab_sea
56        (cubed-sphere configuration will change a little)
57      - grid computations in seaice_init are obsolete now.
58      - cleaned up code a little so that is easier to read (hopefully).
59      - added new (better?) discretizations of default advection and diffusion
60        (turn on with SEAICEuseFluxForm)
61      - replace 1 in 3d global fields by kSurface in growth.F
62      
63  checkpoint58a_post  checkpoint58a_post
64    o seaice:
65      - bug fix in advect.F
66  o shelfice:  o shelfice:
67    - separate shelfice load anomaly from pload (breaks with time    - separate shelfice load anomaly from pload (breaks with time
68      dependent forcing), => introduce constant field shelficeLoadAnomaly.      dependent forcing), => introduce constant field shelficeLoadAnomaly.
