This study focuses on the current generation of commercially available Optical Array Probes instrument families (CIP and 2D-S), and includes perhaps the first detailed laboratory comparison of these instruments with particle velocities approaching jet aircraft speeds (190 m s-1). We demonstrate how electronic time response impacts small particle counting efficiency as a function of particle velocity, and how dead time affects cloud particle measurements. Our laboratory results are corroborated with in-situ cloud measurements of a CIP and 2D-S probe at airspeeds up to 170 m s-1. We also present comparisons of the Depth of Field studies for these probes, suggesting that variations in sample volume calculations must be developed for newer instruments. Together these results highlight the need for the development of improved 2D imaging probe analysis techniques, and reconsideration of some archived cloud microphysics datasets. Improvements in the efficacy of 2D in-situ data will result in more representative cloud PSDs. Reducing uncertainties in observed PSDs is of critical importance as any errors become more pronounced when for calculating cloud radiative properties (2nd moment) and cloud water content (3rd moment).
