     Notes on tags used in MITgcmUV
     ==============================
 
+o tracer advection: 
+ - clean-up and simplify calc_common_factors.F
+ - make a local copy of velocity and pass it (as u,v,r_Trans) to DST tracer 
+   advection subroutine (but still not used within DST advection S/R)
+o rename pkg aim_ocn_coupler to atm_ocn_coupler (later on, will be used without aim)
+
+checkpoint58j_post
+o new driver S/R: LOAD_FIELDS_DRIVER to load external forcing fields
+  from file (collects calls previously in FORWARD_STEP)
+o move call to SEAICE_MODEL from FORWARD_STEP to DO_OCEANIC_PHYS
+o adjoint store dir. adjusted accordingly
+o genmake2
+  replace target "ad_taf" by $(EXE_AD) ; add $(EXE_AD) to the make CLEAN list.
+
+checkpoint58i_post
+o pkg/seaice: add parameter that allows to scale/turn off effect of seaice 
+  on wind stress (SEAICEstressFactor defaults to 1.)
+o Total number of Timers is finite (<=40): comment out 2 non-essential one
+  in the_main_loop.F to avoid Pb (e.g., when running fizhi test)
+o vector_invariant: fix highOrderVorticity(=4.th.Order) advection 
+  on CS-grid: no longer loosing mass.
+o exf & curvilinear-grid: no longer modify longitude xC & xG.
+o pkg/ggl90: fix sloppy output and fix a bug
+o pkg/seaice: added SEAICEuseEVPpickup parameter
+  - Set to false in order to start EVP solver with
+    non-EVP pickup files when using SEAICEuseEVP
+  - fix sign error in diffusion in seaice_calc_rhs
+
+checkpoint58h_post
+* Modifications for bottom topography control
+  o replace hFacC by _hFacC at various places
+  o replace ALLOW_HFACC_CONTROL by ALLOW_DEPTH_CONTROL
+  o add non-self-adjoint cg2d_nsa
+  o update autodiff support routines
+  o re-initialise hfac after ctrl_depth_ini
+  o works for 5x5 box, doesnt work for global_ocean.90x40x15
+* Adding verification for 5x5 box (4-layer) bottom topography control
+
+checkpoint58g_post
+o pkg/diagnostics: implement "periodic averaging diagnostics" (e.g.,
+   used for mean seasonal cycle, mean diurnal cycle); add an example
+   in verification/global_ocean.cs32x15/input.thsice/data.diagnostics
+o pkg/ggl90: 
+  - add parameter (minimum surface kinetic energy)
+  - fix bug (avoiding division by zero)
+o couple pkg/thsice to pkg/seaice:
+  - modify advection in seaice to accomodate new scalar fields to be advected
+  - only muliDimAdection scheme work with seaice/thsice
+  - mapping of thsice-variables to seaice-variables, back and forth
+  - does not break the verification experiments, but does not give the
+    desired results either
+o pkg/seaice
+  - make (default) second order advection a bit less confusing?
+
+checkpoint58f_post
+o couple pkg/thsice and pkg/exf (as a preparation for coupling pkg/thsice 
+  to pkg/seaice): 
+  - new routines thsice_map_exf and thsice_get_exf provide the interface
+  - add an additional formal parameter to thsice_solve4temp 
+o pkg/exf:
+  - add new fields wspeed, snowprecip (to be able to couple to thsice)
+  - correct Stefan-Boltzmann constant
+  - new parameter for longwave surface emittance
+  - separate some stuff from exf_bulkformulae into new routines  
+    exf_radiation, exf_wind
+  - add new parameters and constants: longwave emissivity for ocean, ice 
+    and snow, evaporation parameters over ice
+  - decouple wind/stress computation from ALLOW_BULKFORMULA: always compute
+    either wind from stress or stress from wind
+o pkg/thSIce:
+- split thsice_step_fwd.F in 2 S/R: thsice_step_temp.F & thsice_step_fwd.F
+- put i,j loops inside S/R: THSICE_ALBEDO, THSICE_SOLVE4TEMP, THSICE_EXTEND
+   and THSICE_CALC_THICKN
+- for now, call to THSICE_GET_BULKF remains inside i,j loops.
+- add CPP option: ALLOW_DBUG_THSICE and header file THSICE_DEBUG.h
+  to make debugging easier.
+- affects results (@ truncation level) of global_ocean.cs32x15.thsice: update output
+o pkg/bulk_force: 
+  - clean-up comments and parameters ; 
+  - add new Bulk-Formulae from Large and Yeager, 2004, NCAR/TN-460+STR ;
+o fix bug in aim+thsice albedo: snow & ice thickness arguments were switched;
+  generate new output for test-experiment: aim.5l_cs.thSI
 o results_ad : rename "output.txt_adm" to "output_adm.txt" and change
- testreport accordingly
+  testreport accordingly
