Icing Characterization Based on In-situ Aircraft and Remote Sensing Platform Observations

An aircraft has been outfitted with microwave radiometer[1], cloud particle spectral[2], and liquid water content[3] sensors for icing condition detection and avoidance research. Complementary ground-based microwave radiometer[4], cross polarization lidar[5] and weather radar[6] observations are planned, along with high resolution weather model analysis. We present initial findings from this unique cloud microphysics investigation focused on icing environments.
