-Switch on/off splitting algorithm for cloud droplets (if cloud_droplets is set .TRUE.). If [#splitting splitting] is set .TRUE. every time step the splitting algorithm is executed. The algorithm split particles which fulfill certain criterion's into several super droplets with a reduced number of represented particles of every super droplet. The splitting algorithm can be steered by several parameters (a critical radius, a critical weighting factor,..). This mechanism allows an improved representation of the right tail of the drop size distribution with a feasible amount of computational costs. The limits of particle creation should be chosen carefully! The idea of this algorithm is based on Unterstrasser and Soelch, 2014.

 '' 'const' ''
-      In splitting mode 'const' a critical radius  (radius_split) a critical weighting factor (weight_factor_split) and a splitting factor (splitting_factor) must  be prescribed. Super droplets which have a larger radius and larger weighting factor are split into 'splitting_factor' super droplets. Therefore, the weighting factor of  the super droplet and all created clones is reduced by the factor of 'splitting_factor'.

 '' 'cl_av' ''
-      In splitting mode 'cl_av'  a critical radius (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 1.0E-6 m 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 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'.
