Abstract A new design for airborne cloud-water collection was implemented for testing onboard the NASA C-130 aircraft as part of the North Atlantic Aerosols and Marine Ecosystems Study (NAAMES). The technique involves the separation of droplets from the airstream using a swirl chamber induced via a stator - a set of eight turning vanes - followed by capture and collection of the water for subsequent offline analysis. The operating principle was based on a previous design reported in Straub and Collett (2004), and has been flown previously on the NCAR C-130. We aim to replicate the successes, and improve upon the reported shortfalls, of their design. Here we present details of the design process, laboratory testing, and preliminary results from NAAMES.
