Perpetual years

Running perpetual years

Perpetual years: Running the same year over and over again.

Pick the year you wanto to run. The beginning of this year also has to be the start year ('CLIMAT_startdate') of your simulation.

Set run to perpetual years

To run perpetual years you have to set in your 'gemclim_settings.nml', namelist 'gement' the parameter 'E_schm_perpetual' to the year you want to run over and over again.

    E_schm_perpetual = 1981 ,

Take care of leap years

Unless you are running a leap year set:

    Leap_years_L    = .false.  ( in 'gemclim_settings.nml', namelist 'physics_cfgs' )

    CLIMAT_leap_year=NO;     ( in 'configexp.dot.cfg' )

Lateral boundary conditions

When running LAM make sure that the nest_info-archive for December also contains data for January 1st of the same year.

SST & sea ice

In the file 'configexp.dot.cfg' set 'CLIMAT_anclim' to an empty file.
The scripts need a file to link to but the model must not find anything usable in it.

Set 'UM_EXEC_climato' to a file which contains the climatology (for each month) for 'TM' and 'LG' you want.
Make sure that 'IP2' contains the correct month.
