5      ==============================      ==============================

7    o build_options: ifort+mpi_aces optfile (following Constantinos advise):
8      allow different versions of ifort (8 or 9) and different versions
9       of mpi (mpich or mpich2) to be used with the same optfile.
10      requires to load a netcdf module and set MPI_INC_DIR (see comments inside
11       optfile). Change testing scripts (example_scripts/ACESgrid) accordingly.
12    
13    checkpoint61r
14    o pkg/seaice:
15     - clean up the 3-time levels of UICE,VICE,HEFF,AREA in three steps:
16      1. introduce fields for time step (N-1)
17      2. do not use levels 2 and 3 anymore (but keep them)
18      3. replace 3D versions of UICE,VICE,HEFF,AREA by 2D versions. This
19         includes changes to pkg/thsice/thsice_get_velocity.F,
20         model/src/external_forcing_surf.F, pkg/obcs/obcs_apply_seaice.F, and
21         pkg/obcs/obcs_apply_uvice.F.
22     - completely remove code for leap-frog time stepping for second order
23       advection
24     - adjusted adjoint accordingly;
25       gradient checks have improved by an order of magnitude!
26    
27    checkpoint61q
28    o pkg/seaice: fix bug in free slip boundary conditons for LSOR solver
29     - the boundary conditions along open boundaries are unclear, because the
30       associated masks are set to zero and are thus treated as closed when
31       applying the slip-boundary conditions.
32     - move initialisation of grid variables from seaice_init_varia to _fixed
33    o adding doc/diags_changes.txt
34    o model/src:
35      do_the_model_io: rename few pkg S/R which are called from do_the_model_io,
36       to avoid "_diags" naming if no relation to pkg/diagnostics.
37      ini_theta,ini_salt: fix (at least compile the code) reading from NetCDF
38       file and only call PLOT_FIELD_XYZ if debugMode=T.
39      remove few PLOT_FIELD_XY calls outside initialisation.
40      remove few unnecessary BARRIER.
41    o pkg/salt_plume: add SaltPlumeSouthernOcean to allow disabling
42      of salt_plume package in Southern Ocean
43    o pkg/thsice:
44     - fix hOceMxL in overlap (needed for sea-ice advection);
45       update output of experiment global_ocean.cs32x15.icedyn.
46    o pkg/seaice:
47     - make the (placeholder-)tracer IceAge a little more meaningful
48      by avoiding ridging of age due to convergent ice flow
49     - add diagnostics for surface temperature, atmospheric and oceanic
50       heat flux, and atmospheric and oceanic ice growth
51    
52    checkpoint61p
53    o eesupp (global_max & global_sum):
54     - add one more element to buffer (start at index 0) for GL_MAX/SUM output;
55     - remove starting & endding barrier (no longer needed)
56    o pkg/mdsio, writelocal:
57       works also in multi-threaded when LOCBIN_IO_THREAD_SAFE is undefined
58       (remove the STOP): uses shared buffer IO to store data from all threads
59       and then let master-thread write nThreads tiles.
60    o pkg/mdsio (read/write field):
61     - tiled IO done in 1 piece (all levels at a time);
62     - new header file "MDSIO_BUFF_3D.h" with 3-D buffers.
63     - multi-threaded: allow to read/write local (non-shared) array
64       (was already working with singleCpuIO ; now works also without);
65       => no longer needs barrier call after reading a file (added inside
66       mds_read/write field).
67     - move barrier calls outside gather/scatter_2d to mds_read/write_field
68  o pkg/obcs/exf  o pkg/obcs/exf
69      - exf_getffieldrec.F: add a few ". _d 0" and
70                            add code to catch the case fldperiod = 0.  
71    - obcs_precribe_read.F: change if statements so that they match    - obcs_precribe_read.F: change if statements so that they match
72                            the variable type (_RL)                            the variable type (_RL)

87      remove 2nd exch call in exch2_s3d_rx (no longer needed).      remove 2nd exch call in exch2_s3d_rx (no longer needed).

90      - added SEAICE_CLIM_AIR code, which permits modulation of surface air
91        temperature and humidity over sea ice based on climatological values.
