    786 This parameter is used for [#splitting_mode splitting_mode] = 'const'. It defines the number into how many partiles one particle is divided. This means that, if all other splitting criterion's for one super droplet are fulfilled, splitting_factor-1 new particles (with the same properties as the origin super droplet) are created. The weighting factor of each of the super droplets is divided by the splitting_factor. For [#splitting_mode splitting_mode] = 'cl_av' and  'gb_av' this parameter is calculated automatically and given by the ratio of the actual weighting factor of a super droplet and the approximated number concentration for cloud droplets with a similar radius in a certain volume (grid volume).

    843       In splitting mode 'cl_av'  a critical radius [#radius_split radius_split] and a splitting function must be prescribed. The critical weighting factor is calculated while approximating a 'gamma', 'log' or 'exp'- drop size distribution. In this mode a drop size distribution (discretized in 100 bins in a range from 1.0 µm to 1 mm) is calculated as an average over all cloudy grid boxes. Super droplets which have a larger radius and larger weighting factor are split into 'splitting_factor' super droplets. In this case the [#splitting_factor splitting_factor] is calculated of weighting factor of the super droplet and the approximated number concentration for droplet of such a size. Due to the splitting, the weighting factor of the super droplet and all created clones is reduced by the factor of 'splitting_facor'.
