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. ; FMRC Best Dataset 2024-05-31T19:12:44Z https://pae-paha.pacioos.hawaii.edu/thredds/dodsC/ww3_global/WaveWatch_III_Global_Wave_Model_best.ncd 2024-05-31T19:12:44Z https://pae-paha.pacioos.hawaii.edu/erddap/griddap/ww3_global.nc?Tdir%5B(2021-12-31T00:00:00Z):1:(2021-12-31T23:00:00Z)%5D%5B(0.0):1:(0.0)%5D%5B(-77.5):1:(77.5)%5D%5B(0.0):1:(359.5)%5D%2CTper%5B(2021-12-31T00:00:00Z):1:(2021-12-31T23:00:00Z)%5D%5B(0.0):1:(0.0)%5D%5B(-77.5):1:(77.5)%5D%5B(0.0):1:(359.5)%5D%2CThgt%5B(2021-12-31T00:00:00Z):1:(2021-12-31T23:00:00Z)%5D%5B(0.0):1:(0.0)%5D%5B(-77.5):1:(77.5)%5D%5B(0.0):1:(359.5)%5D%2Csdir%5B(2021-12-31T00:00:00Z):1:(2021-12-31T23:00:00Z)%5D%5B(0.0):1:(0.0)%5D%5B(-77.5):1:(77.5)%5D%5B(0.0):1:(359.5)%5D%2Csper%5B(2021-12-31T00:00:00Z):1:(2021-12-31T23:00:00Z)%5D%5B(0.0):1:(0.0)%5D%5B(-77.5):1:(77.5)%5D%5B(0.0):1:(359.5)%5D%2Cshgt%5B(2021-12-31T00:00:00Z):1:(2021-12-31T23:00:00Z)%5D%5B(0.0):1:(0.0)%5D%5B(-77.5):1:(77.5)%5D%5B(0.0):1:(359.5)%5D%2Cwdir%5B(2021-12-31T00:00:00Z):1:(2021-12-31T23:00:00Z)%5D%5B(0.0):1:(0.0)%5D%5B(-77.5):1:(77.5)%5D%5B(0.0):1:(359.5)%5D%2Cwper%5B(2021-12-31T00:00:00Z):1:(2021-12-31T23:00:00Z)%5D%5B(0.0):1:(0.0)%5D%5B(-77.5):1:(77.5)%5D%5B(0.0):1:(359.5)%5D%2Cwhgt%5B(2021-12-31T00:00:00Z):1:(2021-12-31T23:00:00Z)%5D%5B(0.0):1:(0.0)%5D%5B(-77.5):1:(77.5)%5D%5B(0.0):1:(359.5)%5D

attribute	NC_GLOBAL	summary	String	Through a collaborative effort with NOAA/National Centers for Environmental Prediction (NCEP) and National Weather Service (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.
