Abstract:

Through a collaborative effort with NOAA/NCEP and NWS Honolulu, the University of Hawaii has implemented a global-scale WaveWatch III (WW3) 7-day model with a 5-day hourly forecast at approximately 50-km or 0.5-deg resolution. The global model is forced with NOAA/NCEP's Global Forecast System (GFS) winds. This model is designed to capture the large-scale ocean waves and provide spectral boundary conditions for the Hawaii and other Pacific regional WW3 models. While considerable effort has been made to implement all model components in a thorough, correct, and accurate manner, numerous sources of error are possible. As such, please use these data with the caution appropriate for any ocean related activity.

Purpose:

PacIOOS provides timely, reliable, and accurate ocean information to support a safe, clean, productive ocean and resilient coastal zone in the U.S. Pacific Islands region.

Credit:

The Pacific Islands Ocean Observing System (PacIOOS) is funded through the National Oceanic and Atmospheric Administration (NOAA) as a Regional Association within the U.S. Integrated Ocean Observing System (IOOS). PacIOOS is coordinated by the University of Hawaii School of Ocean and Earth Science and Technology (SOEST).

Statement:

2010-06-20T00:00:00Z New dataset.
2021-12-17T22:04:00Z Replaced erroneous sdir and wdir values with fill values over the period 2015-12-30 through 2017-07-10. Variable names had changed in source data unnoticed, resulting in directional spreading values in these two variables, not wave directions.
2023-09-11T19:25:00Z Aggregation now begins at 2013-01-01T21:00:00Z; will restore files since 2010-11-07T21:00:00Z if and when space permits.
2024-08-06T19:14:00Z Aggregation now begins at 2017-01-01T21:00:00Z; will restore older files if and when space permits.
