Accuracy of measurements of cloud ice water content by the Nevzorov probe

This article studies the accuracy of measurements of cloud ice water content (IWC) in glaciated clouds using the airborne Nevzorov LWC/TWC probe. The Nevzorov probe is a constant temperature hot-wire instrument for measurement of liquid water content (LWC) and total (ice+liquid) water content (TWC). IWC was calculated from measurements of TWC and LWC. The phase discriminating capability was tested in a wind tunnel using frozen sprays. The IWC measured in natural clouds by the Nevzorov probe was compared to that calculated from PMS OAP-2D images. It was found that IWC derived from the Nevzorov and OAP-2D imagery correlates well. __________________________________
