     Notes on tags used in MITgcmUV
     ==============================
 
+checkpoint46m_post
+o modified testscript to return -- when there are no lines of "%MON" output 
+o added new flag "quasiHydrostatic" for QH mode
+  and new routine quasihydrostaticterms()
+o added 2*Omega*Cos(phi)*W to u equations (non-hydrostatic Coriolis term)
+  New routine: mom_u_coriolis_nh()
+o fixed sign of non-hydrostatic metric terms in u and v equations.
+  Depend on correct sign of gravitySign.
+o added work.pc* to .cvsignore in aim directories using ifc
+o introduced flag for controllin non-hydrostatic metric terms
+o removed gravitySign from PARM04
+o switched to g77/ifc from pgf77 in aim experiments
+
+checkpoint46l_post
+o made convective adjustment work with pressure coordinates:
+ - changed the direction of k-loop in convective_adjustment.F for the
+   case of pressure coordinates (OCEANICP,ATMOSPHERIC buoyancyRelation)
+ - adjusted the reference pressure k-index in convective_adjustment.F
+ - adjusted the convection condition in convect.F (in analogy to
+   calc_ivdc.F)
+ - convective_adjustment no longer computes anything on the halos
+ - removed the warnings about negative salinity from find_rho.F and
+   find_alpha.F; instead the new routine look_for_neg_salinity, called
+   at the beginning of find_rho, find_alpha, and find_beta, does a 
+   check of the entire slice, if CPP-option 
+   CHECK_SALINITY_FOR_NEGATIVE_VALUES is defined
+checkpoint46l_pre
+
+checkpoint46k_post
+o fixed the verification/global_ocean.90x40x15 experiment:
+ - new bathymetry (the world according to A., JMC, and M.)
+ - new initial fields and forcing fields (*.bin files)
+ - new POLY3.COEFFS (for the next release one should switch to a full
+   equation of state: JMD95P or MDJWF)
+ - fixed several errors and redundancies in the data file
+ - experiment uses looped cells
+ - added matlab directory with diagnostic scripts for plotting of output
+
+o S/R aim_initialise.F replace S/R aim_init from file aim_do_inphys.F:
+ - read AIM physics parameters from a file (data.aimphys)
+ - set defaults values = F.Molteni paper (Clim.Dyn., 2002)
+
+checkpoint46j_post
+o split calc_exact_eta in 2 S/R : integr_continuity & update_etaH
+o move wVel computation at the end of the time step, in S/R integr_continuity
+o create specific S/R to exchange T,S before DYNAMICS (for stagger time step)
+o update timeave pkg for wVel diagnostic.
+checkpoint46j_pre
+
+checkpoint46i_post
+o Clean up AIM package (and keep the results unchanged):
+  include CPP_OPTION and use IMPLICT NONE in all routines ; 
+  declare all the variables _RL ; use _d 0 for all numerical constants.
+  use ifdef ALLOW_AIM everywhere. And now AIM can be used with g77 !
+
+checkpoint46h_post
+o cleaned up the use of rhoNil and rhoConst. 
+  - rhoNil should only appear in the LINEAR equation of state, everywhere 
+    else rhoNil is replaced by rhoConst, e.g. find_rho computes rho-rhoConst
+    and the dynamical equations are all divided by rhoConst
+o introduced new parameter rhoConstFresh, a reference density of fresh 
+  water, to remove the fresh water flux's dependence on rhoNil. The default
+  value is 999.8 kg/m^3
+o cleanup up external_forcing.F and external_forcing_surf.F
+  - can now be used by both OCEANIC and OCEANICP
+checkpoint46h_pre
+
+ Added code to convert surface volume flux (fresh water) into
+ a mass flux when using P coordinates in the ocean (OCEANICP).
+ Note: It assumes you have set rho0=rhoConst=density of fresh water.
+
+checkpoint46g_post
+o Include a new diagnostic variable phiHydLow for the ocean model
+  - in z-coordinates, it is the bottom pressure anomaly
+  - in p-coordinates, it is the sea surface elevation
+  - in both cases, these variable have global drift, reflecting the mass
+    drift in z-coordinates and the volume drift in p-coordinates
+  - included time averaging for phiHydLow, be aware of the drift!
+o depth-dependent computation of Bo_surf for pressure coordinates 
+  in the ocean (buoyancyRelation='OCEANICP')
+  - requires a new routine (FIND_RHO_SCALAR) to compute density with only 
+    Theta, Salinity, and Pressure in the parameter list. This routine is 
+    presently contained in find_rho.F. This routine does not give the
+    correct density for 'POLY3', which would be a z-dependent reference
+    density.
+o cleaned up find_rho
+  - removed obsolete 'eqn' from the parameter list.
+o added two new verification experiments: gop and goz
+  (4x4 degree global ocean, 15 layers in pressure and height coordinates)
+checkpoint46g_pre
+
+checkpoint46f_post
+o Enable tangent linear (forward mode) gradient checks:
+  - extended active file handling to g_... files
+  - added TANGENT_SIMULATION to theSimulationMode
+  - extended grdchk package accordingly
+o added tangent linear setup in verification/carbon/code_ftl
+o added adjoint setup in verification/front_relax/code_ad
+
 checkpoint46e_post
 o Added new equation of state -> MDJWF
