Part III. Appendix 4: User Outreach3) The parameters that require measurement by a system like ISOOS include:a. Deep water directional wave gagingb. Sufficient nearshore directional wave measurement capability to validate propagation models,and to account for modification by wind over the shelfc. Wind measurement on the shelfd. Long wave and sealevel variation measurement in deep water (GPS makes this easy, now)e. Rapid response broad area assessment of beach and dune health following severe hazards.f. Seasonal broad area 3D mapping of beaches, dunes and cliffs.4) The measurements must lead to useful products. Although they will have archival value, theymust provide pre-hazard warnings or post-hazard data in a timely and useful form. Therefore,models which convert measurements into easily understood web pages, radio announcements oreven siren blasts are a necessary part of the system. The overall reliability of the system must bevery high because users will rely on it. Forecasts must be updated rapidly, often and be sufficientlyaccurate that they will be taken seriously by those in harms way. For coastal hazard information,hourly updates would seem to be sufficient.Richard J.
