Short summary
High-resolution images of ice crystals acquired by environmental scanning electron microscope reveal a wide array of surface complexities at scales from 100 nm to greater than 10 microns. These observations include ice crystals grown in the low-pressure microscope chamber and crystals grown externally under cirrus cloud conditions and then transferred for imaging. The results suggest that accounting for microscale complexity is critical for understanding cirrus interactions with radiation.
