Purpose, Description

This is the flux calculator component of the IOW ESM. All coupling fields that are communicated between atmospheric and bottom models are passed through or calculated by this component. The commnuicated information is mapped from the models' grid to the exchange grid and vice versa.

changes

• enable bias corrections for exchanged fluxes
  • currently only the evaporation flux can be corrected in an additive fashion
  • however, module bias_corrections can be easily extended
  • correction is applied as anual cycle, i.e. for each month there should be a correction file (NetCDF) that contains a field that is added to the actual flux
  • these files must be placed in folder called corrections that is placed in the input folder called flux_calculator
  • the files must be named mass_evap-MM.nc for the evaporation correction
  • the MM indicates the month and goes from 01 to 12
• the Fortran code can now call python routines via the Fortrasn module call_python
  • currently this used to calculate the current month from the initial start time and the current time step *build script templates for new target machine have been added

changes

• fluxes can now be calculated according to
  • the MOM5 ocean model (formulars the same as in CCLM but with different transfer coefficients)
  • the RCO ocean model, Meier et al., SMHI REPORTS OCEANOGRAPHY No. 26, August 1999
  • caution this is still a bit experimental

changes

• initial release
• flux calculator can couple MOM5 ocean model and CCLM atmospheric model
