Short summary

This paper introduces BinMod1D, a new open-source Python package that allows users to easily, quickly, and explicitly calculate the distribution evolution of rain or snow particles undergoing collision-coalescence and collisional breakup in three different model modes. Validated against known solutions and meteorological scenarios, it is intended for developing reference solutions for assessing the performance of radar, machine learning, and AI models in estimating particle distributions.
