4      Notes on tags used in MITgcmUV      Notes on tags used in MITgcmUV
5      ==============================      ==============================
6    
7    o eesupp/src:
8      - change default for opening scratch files to avoid STATUS='SCRATCH'
9      - close scratch files with STATUS='DELETE'
10      - changes affect eeset_parms.F and open_copy_data_file.F and many routines
11        that read namelists (because they close the scratch files)
12      - you can revert to old default by setting USE_FORTRAN_SCRATCH_FILES
13        in CPP_EEOPTIONS.h (tested in ideal_2D_oce/code & lab_sea/code_ad)
14    o pkg/atm_phys:
15      - fix unset arguments in (unused) S/R surface_flux_0d.
16    o eesupp/src:
17      - add argument "procId" to S/R EESET_PARMS to fix  scratchFile1 & 2 setting
18        (case TARGET_BGL or TARGET_CRAYXT) for early call (from eeboot_minimal.F):
19        called with myProcId in eeboot.F and with mpiMyWId in eeboot_minimal.F
20    o pkg/streamice:
21      - remove blank between _EXCH_XY_RL and "()", which my Apple Xcode
22        preprocessor /usr/bin/cpp cannot interpret; 3 instances in total in
23        streamice_driving_stress_fd.F and streamice_advect_2dtracer.F
24    o pkg/diagnostics:
25      - new option to allow to cumulate thickness-factor (hFac) weighted field
26        (if field permitted); implemented by changing sign of "jdiag" pointer
27        (> 0: cumlulate field, < 0: cumulate hFac weighted field).
28        a) restricted to 3-d (Nr levels), level centered diagnostics at U,V or Cell
29           center position (gcode(2)='U','V','M' & gcode(3,5,9:10)='R',' ','MR')
30        b) for now, activated by setting fileFlags 3rd character to 'h'.
31    
32    checkpoint66i (2017/07/18)
33    o pkg/cheapaml:
34      - add parameter "useRelativeWind", default set to False; this change the
35        previous setting which was always using relative wind.
36    o add hooks for the Parallel Data Assimilation Framework PDAF
37        (http://pdaf.awi.de/) in eeboot_minimal.F and the_main_loop.F;
38        to use set CPP-flag USE_PDAF in CPP_EEOPTIONS.h
39    o pkg/exf:
40      - interpolation of vector fields (exf_interp_uv.F): fix bug in calculation
41        of South-Pole mean value.  
42      - interpolation near the poles, case where second additional row is at the
43        pole (or beyond the pole and moved to the pole): change first addition row
44        value to a linear interpolation between pole and 1rst (S.pole)/last (N.pole)
45        row (instead of just a copy of it).
46    o pkg/seaice:
47      - prevent JFNK and KRYLOV solvers from trying to reduce a residual of 0
48      - add the option to compute no-slip du/dy, dv/dx (i.e.
49        the offdiagonal strain rate e12) by a second order approximation
50        on the boundary; works only with JFNK, KRYLOV, or EVP solvers, because
51        it is too messy to implement for the implicit LSR matrix.
52        SEAICE_2ndOrderBC = .FALSE. by default
53    
54    checkpoint66h (2017/06/02)
55    o pkg/seaice:
56      - add new routines to compute stress tensor components and stress tensor
57        divergence to be reused in s/r seaice_lsr and s/r seaice_calc_lhs
58      - change names of diagnostics SIsigI/II (commonly used for invariants)
59        to SIsig1/sig2 (more common for principal components) to avoid confusion
60  o pkf/exf:  o pkf/exf:
61    - add a stop if useRelativeWind with un-updated uwind/vwind (e.g., constant);    - add a stop if useRelativeWind with un-updated uwind/vwind (e.g., constant);
62      similarly, stop if rotateStressOnAgrid with constant wind-stress.      similarly, stop if rotateStressOnAgrid with constant wind-stress.
