Short summary
This study evaluates the implementation of predicted rime mass distribution a bin microphysics scheme. Based on the ‘fill-in’ concept, the model allows a smooth transition between unrimed and graupel ice particles. The implementation is tested for an idealized squall-line system and a heavy snowfall event observed by ground-based instruments in the Korean Peninsula. The new model version gives a better agreement with the observations with significant changes for precipitation.
