Quantitative three-dimensional ice roughness from scanning electron microscopy

Editors’ Highlight—This paper presents a method for using scanning electron microscope imagery to infer surface morphology of tiny ice crystals. This method extracts three-dimensional information about the ice surfaces, and finds some unexpected features. There are long, deep valleys in some instances, and rounded hills in others. Characterizing these features may help to understand how rough ice surfaces behave in real cirrus clouds. At the same time, understanding how these rough surface features scatter radiation, will lead towards better understanding of how such ice crystals affect Earth’s climate.
