VOCALS Regional Experiment (REx)

VOCALS-Rex will collect datasets required to address a set of issues that are organized into two broad themes:

• Aerosol-cloud-drizzle interactions in the marine boundary layer (MBL) and the physicochemical and spatiotemporal properties of aerosols

• Chemical and physical couplings between the upper ocean, the land, and the atmosphere.
