Ice crystal characterization in cirrus clouds: a sun-tracking camera system and automated detection algorithm for halo displays

Ice crystal characterization in cirrus clouds: a sun-tracking camera system and automated detection algorithm for halo displays

Halo displays in the sky contain valuable information about ice crystal shape and orientation: e.g., the 22° halo is produced by randomly oriented hexagonal prisms while parhelia (sundogs) indicate oriented plates. HaloCam, a novel sun-tracking camera system for the automated observation of hal...
