* atmospheric p*: geopotential anomaly scaled by (p/p_0)^kappa instead of (p/p_0) * add a curious option (select_rStar=1,nonlinFreeSurf=4) to test p* * specific volume (used to compute geopotential) includes water vapor effect
o avoid using any hFac in calc_phi_hyd ; use Ro_surf,R_low instead. NLFS + p-coord.: eta*Alpha' is not longer lagging 1.time-step behind ( change results of global_ocean_pressure ) NLFS + z-coord.: add eta*Alpha' contribution. accurate phiHyd when using interface-W at the middle between 2 center. ( change results of ideal_2D_oce ) o includes r* 2nd term in potential gradient.
left from previous modifications.
o New S/R for diagnostic of bottom pressure (phi0surf contribution was missing in checkpoint48d_post)
in preparation for r*: a) use pre-computed gradient of hydrostatic potential: changes in timestep.F & mom_cdscheme.F affect results of ideal_2D_oce b) move phi0surf from calc_phi_hyd to calc_grad_phi_hyd : => affects results of glob_oce_pressure (different truncation error)
in preparation for r*: new S/R (calc_grad_phi_hyd.F) to compute Hydrostatic potential gradient. pass the 2 comp. of the grad. as arguments to momentum S/R. for the moment, only used if it does not change the results.
* allows a more accurate definition of Ro_Surf (selectFindRoSurf=1) when using P-coordinate; only implemented for atmospheric config.
differentiable version of checkpoint46n_post o external_fields_load now part of differentiation list o pressure needs multiple storing; would be nice to have store_pressure at beginning or end of forward_step, e.g. by having phiHyd global (5-dim.) (NB: pressure is needed for certain cases in find_rho, which is also invoked through convective_adjustment). o recomputations in find_rho for cases 'JMD95'/'UNESCO' or 'MDJWF' are OK. o #define ATMOSPHERIC_LOADING should be differentiable o ini_forcing shifted to begining of initialise_varia
Added new routine quasihydrostaticterms() and flag "quasihydrostatic" which is false by default and enables QH mode. Exlcusive with nonhydrostatic flag.
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
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)
Changes necessary for ocean in p-coordinates - Added new buoyancy relation = 'OCEANICP' - Added new parameters = gravitySign (this used to be contained inside the factor dRdZ which I added when we first switched to R coordinates). X GM/Redi is not compatible (yet) X bottom drag and no-slip need to be debugged.
Added pressure loading term and experiment based on Wunsch and Stammer (1997) o new field in FFIELDS.h, etc... o new cpp flag ATMOSPHERIC_LOADING o Changed hFacC to _hFacC in calc_phi_hyd.F o Added SHORTWAVE_HEATING to some files for consistency
Deleted single apostrophy (').
Bringing comments up to data and formatting for document extraction.
Removed maskUp (no longer needed).
add several forms of the geopotential integration with partial cell.
Modifications/fixes to support TAMC differentiability (mostly missing or wrong directives).
Modifications and additions to enable automatic differentiation. Detailed info's in doc/notes_c37_adj.txt
change units of PhiHyd (ocean) to have unified units for all potential Phi
Made sure each .F and .h file had the CVS keywords Header and Name at its start. Most had header but very few currently have Name, so lots of changes!
Merged changes from branch "branch-atmos-merge" into MAIN (checkpoint34) - substantial modifications to algorithm sequence (dynamics.F) - packaged OBCS, Shapiro filter, Zonal filter, Atmospheric Physics
Rescaling of forcing fields done immediately after reading fields.
Modifications to include TAMC directives, tape key computations and initialisations to make code TAMC compatible. Routines the_model_main.F and initialise_fixed.F are left unchanged for the moment. (P.H.)
Changes to allow for atmospheric integration builds of the code
Consistent isomorphism changes
Consistent isomorphism chages

Isomorphism consistency changes
Spelling change!
