TOPAZ EnKF with BGC assimilation

main update

Following updates are for making TOPAZ EnKF flexible for hycom configuration options:

  • hycom configuration files, regional.grid.(a,b) and regional.depth.(a,b), are read through new modules:
m_get_mod_cnfg.F90
m_io_hycom.F90
  • depth read from regional.depth.(a,b) is used for making land mask in Prep_Routines/m_get_def_wet_point.F90 without using meanssh.uf

notes:

  • This change removes requirement of depth*.uf file to provide depth information both to EnKF and prepobs.
  • configuration-specific meanssh.uf and re_sla.nc are still required for SLA data prepobs.
  • BGC observations: SCHL, CHL, POC, NIT, SIL, PHO, OXY are NOT ready to be assimilated.

TODO:

  • read meanssh.nc only for SLA assimilation.
  • register SCHL, CHL, POC, NIT, SIL, PHO, OXY.
  • add m_global_analysis.F90 for ecoregion-dependent parameter estimation.
  • add analysis masks based on mixder layer depth, sea ice concentration and surface nitrate concentration.
