  Abstract: Systematic observations of atmospheric optical phenomena can reveal much about the physical properties of normally inaccessible layers of the troposphere, for example at cirrus altitude. Optical displays are influenced by the ice crystal shapes, sizes, orientations, and particle densities. This research aims to utilize these optical phenomena for remote probing of atmospheric conditions that affect the color, angular intensity distribution, brightness, and type of optical displays, including halos, parhelia, and pillars. An allsky camera serves for long-term observation and data collection on frequency, seasonal distribution, and type of optical displays at the University of Minnesota-Morris. We present our work on image analysis software for the automatic detection of the presence of common halo-related optical phenomena. In addition, we present our work on the development of a simulation aiming to correlate the observed angular intensity distribution with the types, sizes and orientations of ice crystals present in the generating layer.
