  1. An Overview of the 1999 Coastal Predictive Skill Experiment at LEO-15 Scott Glenn, Oscar Schofield, John Fracassi, Mike Crowley, Sage Lichtenwalner Rutgers University Doug Webb Webb Research Corporation Chris von Alt Woods Hole Oceanographic Institution

  2. NOPP Objectives • Establish a National Littoral Laboratory • Deploy a Real-Time Multi-Disciplinary Coastal Ocean Observatory • Develop a Data-Assimilative Coupled Ocean-Atmosphere Coastal Forecast Model • Encourage Community Involvement Through an Open-Access Architecture

  3. NOPP Objectives • Operate the System in a Continuing Series of Coastal Predictive Skill Experiments 1998 - Improve Nowcast Skill • Assimilation of remote sensing surface data, and • Shipboard/AUV adaptive sampling subsurface data 1999 - Improve Forecast Skill • Improved surface, bottom and lateral boundary conditions • New turbulent closure schemes • Physical/bio-optical adaptive sampling with ships and AUV’s
