The HOLODEC (Holographic Detector for Clouds) flew during the IDEAS 3 (Instrument Development and Education in Airborne Science Phase 3) project in August and September 2003 over northeastern Colorado. Holography, unlike imaging has no depth of focus, thus HOLODEC has a constant and well defined sample volume. Holography also records information in all three spatial dimensions. HOLODEC can measure the 3-D position, size and 2-D projected shape of ice crystals. It can therefore detect which ice crystals are shards and which are natural because shards will appear as strongly localized high concentrations of ice crystals in its sample volume. Presented are small and large ice crystal (10µm to 2000µm) number densities and size distributions from HOLODEC compared to that of the PMS 2DC, 2DP, and SPEC HVPS probes flown during IDEAS 3.
