5      ==============================      ==============================
6    
7    o AIM+thSIce: fix sign of Short-Wave through the Ice ;
8      update output.txt of exp. aim.5l_cs.thSI
9    o various mnc cleanups and improvements:
10      + shrink lookup tables by factor of ~4
11      + better error reporting when running out of lookup space
12      + able to handle longer path/file names (up to 500 chars)
13    o adjoint:
14      - Another overhaul of store dirs. for NLFS to eliminate  "hidden" recomputations.
15      - TBD: "hidden" mom_vecinv recomp. in dynamics
16    o change forcing_In_AB to affects both T,S forcing and Momentum forcing
17     (allow to differentiate between forcing components using new integer flags:
18      momForcingOutAB=1/0 & tracForcingOutAB=1/0)
19     and add new flag to put Dissipation tendency out of Adams-Bashforth.
20    o ecco
21      - enable trend removal from SSH anomaly obs.
22    o adjoint
23      - a fix for PmEpR when #undef EXACT_CONSERV
24      - fix of "hidden" recomp. in thermodynamics (no TAF warnings)
25      - try to fix "hidden" recomp. in forward_step for NLFS
26        (NLFS seems broken sometimes after I checked it in)
27    o seaice:
28     - add c-grid version of the dynamic solver:
29       + three new routines that are the c-grid substitute lsr, dynsolver
30         and ostres
31       + put a few fields that were local to dynsolver into global common
32         blocks, so that I can move the computation of stresses etc into
33         seaice_lsr (saves coding but may break the adjoint).
34     - replace more hardwired parameters by runtime parameters
35     - add ice masks that mask the rhs of the implicit solvers where there
36       is no ice (commented out in seaice_dynsolver, because i am not sure
37       if this works properly), eventually this should replace the clipping
38       of ice velocities in seaice_dynsolver to +/-40cm/s.
39    o remove the BUILD_INFO.h include from CPP_EEOPTIONS.h and explicitly
40      include it only where its needed
41    o move balancing of fluxes before the call of external_forcing_surf
42    o seaice:
43      - correct units of turning angles (now they are really in degrees)
44      - move computation of GWATX/Y out of main routine into dynsolver
45      - initialize GWATX/Y in seaice_init
46    o Apply mask on Fresh-Water flux (needed for SSH forcing).
47      update output.txt of exp. global_ocean_ebm & cpl_aim+ocn (affects cg2d residual)
48    o seaice: add runtime flags for turning angles (default to zero)
49    o Adding runtime parameter to exf/, ctrl/, to remove on-the-fly global mean
50      and trend from exf forcing and ctrl control adjustments
51    o fix variable aliasing in gad_calc_rhs that cannot be handled by TAF
52      (since checkpoint57x_post)
53    o change the default rotation period to 86164.s = the Earth rotation
54    o 1rst implementation of Implicit IGW using the 3-D solver (use3Dsolver=T)
55      and based on a reference stratification. Tested within hs94.cs-32x32x5.
56    o seaice advection: add code for choosing between the default (2nd order
57      central differences) and multiDim advection schemes provided by
58      pkg/generic_advdiff
59    o seaice:
60      - removed all references to SEAICE_GRID.h fields from
61        dynsolver, advect, diffus, lsr, without changing the results of lab_sea
62        (cubed-sphere configuration will change a little)
63      - grid computations in seaice_init are obsolete now.
64      - cleaned up code a little so that is easier to read (hopefully).
65      - added new (better?) discretizations of default advection and diffusion
66        (turn on with SEAICEuseFluxForm)
67      - replace 1 in 3d global fields by kSurface in growth.F
68      
69  checkpoint58a_post  checkpoint58a_post
70    o seaice:
71      - bug fix in advect.F
72  o shelfice:  o shelfice:
73    - separate shelfice load anomaly from pload (breaks with time    - separate shelfice load anomaly from pload (breaks with time
74      dependent forcing), => introduce constant field shelficeLoadAnomaly.      dependent forcing), => introduce constant field shelficeLoadAnomaly.
