NOAA produces ocean surface (10 m level) wind forecasts by applying diagnostic boundary layer procedures to the large-scale wind forecast produced by N~C's global atmospheric model.

As noted in Table E-3, current marine weather forecasts do not meet these perceived requirements. Coastal users, including recreational boaters and fishermen, commercial fishermen, marinas, port authorities, and others, require highly accurate

will provide valuable data for this area, although it will also require expert interpretation by government or private sector value-added groups before it is useful to civilian end users. The expansion of the GMWAVE model to other coastal ranges during the next year should allow the 50 km spatial requirement of nearshore users to be met, although two-dimensional information will still not be readily available to civilian users.

National Weather Service The National Weather Service is the major source of user friendly forecast information. NWS offices provide coastal forecasts, offshore forecasts, and high-seas forecasts as well as gale and storm and special marine warnings.

The nearshore constituency is considerably larger than the high-seas constituency, and there are also significant benefit factors to be considered relative to the impact of improved forecast on environmental issues within the oil, gas, and waste disposal industries. It was the working group's conclusion that the coastal region would likely derive the greatest benefit of meeting perceived forecast requirements.

· Regarding the USCG's military mission it was pointed out that accurate wind and wave forecasts are required to plan and execute port approach operations, that is, minesweeping. · Spatial resolution, temporal resolution, forecast horizon, and accuracy requirements were detailed in the USCG's comments and covered all ranges of the perceived requirements outlined Table E-2 (depending on the area and specific mission application)
