Short summary

Arctic low clouds containing both droplets and ice crystals strongly impact sea ice and therefore require accurate modeling. Using a high-resolution atmospheric model, we found that particle and ice concentrations, alongside ice crystal shape, strongly dictate the simulated cloud. Therefore, these specific properties should be prioritized during future Arctic observational campaigns. Furthermore, atmospheric models must be able to represent a variety of ice crystal shapes.
