VOCALS Regional Experiment (REx) Field Program to address VOCALS science questions Chiefly sponsored by NSF and NOAA, with contributions from ONR, DoE, and international agencies When: Oct-Nov 2008 Scientific Program Overview NSF Proposal Robert Wood, VOCALS-REx PI, University of Washington Christopher Bretherton, GEWEX/GCSS Representative, University of Washington Barry Huebert, SOLAS Representative, University of Hawaii C. Roberto Mechoso, VOCALS Science Working Group Chair, UCLA Robert Weller, Woods Hole Oceanographic Institution

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.
