Counterflow Virtual Impactor (CVI) [Twohy]

Project:

ICE-L

Summary

The Counterflow Virtual Impactor (CVI) dataset is one of several aircraft data sets collected on the NSF/NCAR Research Aviation Facility (RAF) C-130Q Hercules aircraft (Tail Number N130AR) as part of the Ice in Clouds Experiment -L (ICE-L). The counterflow virtual impactor (CVI) separates droplets or ice crystals from the ambient aerosol and evaporates the condensed water, producing cloud droplet residual particles and water vapor. Cloud droplet number (as number of residual particles after evaporation) and condensed water content measurements were taken using the CVI onboard the NSF/NCAR C-130 from Nov 7-Dev 16, 2007. Data are in NASA Ames format. UPDATED 2011-02-01
