Experiment Atlantic ERA 73


General Information


Purpose of the Experiment

The purpose of the experiment is the investigation of the sensitivity of the upwelling in the Atlantic eastern boundary currents to the wind- and radiation forcing. Solar radiation is reduced, Bodin formula is used.


Area and time coverage

  • regional model: 10°W - 18°E, 33°S - 8°N
  • initialisation time: 1999,07,20,0,0,0
  • first output time stamp: 1999.07.22
  • last output time stamp: 2009.06.24


Specific information

The model is integrated over about 10 model years. Important parameterisations:

  • positive mdfl swebe advection
  • kpp vertical mixing scheme
  • additional passive model tracer
  • Manizza shortwave radiation scheme - chlorophyll from satellite data
  • wave model and resuspension of sediments enabled
  • tidal mixing switched on
  • the sea level air pressure does not act onto the ocean


Specific namelist setup


Atmospheric forcing and OBC

  • QuikSCAT daily winds combined with NCEP 6-hourly data
  • ERA interim amosphere temperature, pressure and humidity for heat flux and moisture flux calculation, ERA precipitation
  • ERA interim clouds for short wave radiation
  • baroclinic OBC: 10 day temperature and salinity from ECCO simulations
  • barotropic OBC: 12 hourly sea level from ECCO simulations


Known errors and shortcomings and corrections


  • zmax_pen=800 in ocean_shortwave_gfdl_nml is changed to zmax_pen=1800
