Abstract
A system and method for ice crystal detection and qualification are disclosed. The system for ice crystal detection may include an aircraft weather radar and processing circuitry. The aircraft weather radar may perform scans at one or more elevations at successive times. The processing circuitry may calculate power and reflectivity values based on the scans. The processing circuitry may further compare the power and reflectivity values to threshold values to determine the presence of ice water content. The processing circuitry may display different colors on a display for areas in which the power and reflectivity values are lower than the threshold values.
