Puerto Rico, December 2004

A field project on the East Peak at Puerto Rico, with the objective to characterize cloud formation in the tropical trade wind region, using the Aerodyne AMS in combination with a counterflow virtual impactor (CVI) in order to study cloud droplet residual compostion.

In 2011 we returned for a follow-up project named "PRADACS".
