My group has used the Brechtel CVI inlet on-board research aircraft extensively to explore the CCN properties of stratocumulus clouds off the coast of California with great success. Intercomparisons of the cloud drop concentrations measured by wing-mounted optical sizing probes and the CCN number concentrations measured at the same time by a condensation particle counter deployed on the CVI sample flow showed excellent agreement, in part because Brechtel dedicated the effort to characterize the drop size dependent losses in their system. Working with Brechtel over the years, they have consistently demonstrated their commitment to quality and customer service.
