On going work on alpha v4.0

Various issues to be solved before the beta version :[[BR]]

• ISOMIP & OVERFLOW — Issue with ln_zco, ln_zps, ln_sco ==>> SIMONA

• sbcisf: issue with drag coefficient: made all drag option available with ISF (cf !!gm comment replicated below)

  !!gm  NB  use pCdU here so that it will incorporate local boost of Cd0 and log layer case :
  !!         zustar(:,:) = SQRT( rCdU_top(:,:) * SQRT(utbl(:,:) * utbl(:,:) + vtbl(:,:) * vtbl(:,:) + r_ke0_top) )
  !! or better :  compute ustar in zdfdrg  and use it here as well as in TKE, GLS and Co
  !!
  !!     ===>>>>    GM  to be done this chrismas
  !!         
  !!gm end
  

• dynspg_ts.F90 ===>>> zwz zhf … calculation to be revisited (probably generic one is needed)

• dynbfr.F90 ==> move this routine in zdfdrg and call it in dynzdf if explicit drag are used

• diatmb ==>>> control by iom_use SVP + top/bottom velocities are not at mkbt mibt

• DIA ==>>> create a diagnostic manager called in step which calls all dia... routines (NB: one timing for all diag)

==>>> decide whether digs. are control by iom_use or namelist param (I prefer the former option)

• osmosis ==>>> move the restart inside zdfosm.F90 not in step.F90

• check all " !!gm " ==>>> solve the reported issues if possible

• bi-perio : create a "true" bi-periodic case that work in all MPI domain decomposition

• Remove the lbc_lnk_bdy (a agreement in needed for that)

• OFF_SRC dyndta replace the " USE => " and use a local array

• model time step : r2dt to be defined only 1 time (in step ?) ==>>> use r2dt everywhere (remove all z2dt)

• C1D moved in TEST_CASES ===>>> from Romain's work + remove key_c1d

• sbcice_if : introduce a sbc_ice_if_init and create the climatological file ==>>> Simona if you want ?

• Closea ==>>> test case to be created from ORCA2 ==>>> Simona?

• iceberg : #1602 (heat flux) and #1595 (ifs & icb)

• iceberg : use iceberg thickness integrated current ==>>> #1900 (dev of Merino to be committed)

• energy dissipation diag to be added as in v3.6 stable

• remove : key_trdmxl_trc & key_trdtrc

• create initial state of ORCA2 for TESO10

Note for Christian:

• p4zsbc ===>>> bug correction (misplaced logical)

• p4zflx (p4z_flx_init) :

  !!gm  BUG !!!   ===>>>  ln_presatm and ln_presatmco2 are used below, but read in namelist 
  !!gm                    at the end of the routine via a CALL to CALL p4z_patm( nit000 )
