    v36 v37  
    160160The implementation for the Lorenz-96 model has a wide range of options. For the full set, we recommend to check the list in the file init_pdaf.F90 in the directory lorenz96. Essentially all of the options can be specified on the command line in the format '-VARIABLE VALUE', where VARIABLE is the name of the variable in the program and VALUE is its value. The experiments in `runasml.sh` are executed like
    161161{{{
    162 ./pdaf_lorenz_96 -total_steps 5000 -step_null 1000 -dim_ens 30 -filtertype 1 -forget 0.99 -file_asml t1_N30_f0.99.nc
     162./pdaf_lorenz_96 -total_steps 5000 -step_null 1000 -dim_ens 30 -filtertype 6 -forget 0.99 -file_asml t1_N30_f0.99.nc
    163163}}}
    164164The meaning of the different options is the following:
    … …  
    167167|| dim_ens || ensemble size || 30
    168168|| file_asml || the name of the output file || assimilation.nc ||
    169 || filtertype || Specifies the filter to use; 1 sets the SEIK filter || 1 ||
     169|| filtertype || Specifies the filter to use; 6 sets the filter ESTKF || 1 ||
    170170|| forget  || value of the forgetting factor for multiplicative variance inflation || 1.0 ||
    171171|| step_null || initial time step of experiment. This specifies the offset of the observations which are generated from a model forward run. A value 1000 avoids the spin-up phase of the model || 0 ||
