Measurements of ice water content (IWC) and mean ice‐crystal size and concentration made by two in‐situ probes, CVI and PVM, were compared on the DC‐8 aircraft during SUCCESS flights in orographic ice clouds. The comparison of IWC in these wave clouds, that formed at temperatures of about −38 °C on April 30 and −62 °C on May 2, 1996, showed good agreement. The comparison of ice crystal concentrations agreed better for the April‐30 clouds than for the May‐2 clouds; and the effective radius compared for both probes and for remote retrievals from aircraft and satellite for a segment of the Berthoud wave cloud (May 2) agreed within 30%. The measured parameters of the ice crystals were similar to earlier measurements and recent modeling of cold wave clouds.
