Brechtel - Model 1204 - Aircraft Based Counterflow Virtual Impactor Inlet System (CVI) Brochure

 The Brechtel Model 1204 CVI is a virtual impactor inlet ideal for probing the detailed properties of actual CCN inside real clouds. The CVI was developed for aircraft deployment so researchers could explore aerosol-cloud interactions across a broad spectrum of cloud types and under different air mass source region conditions. Extensively wind-tunnel tested to characterize size-dependent transmission efficiencies, the CVI inlet has been successfully deployed in multiple field campaigns where excellent agreement was found between wing-mounted cloud probes and instruments sampling the CCN from the CVI.
