Nearshore wave time-series: CMIP6 future period 2020-2050 - U.S. Canada border to Norton Sound, Alaska

netCDF files are self-contained and attribute information may be found in the header of the file itself. These files are available for Attributes are latitude, longitude and depth for each location, as well as significant wave heights (Hs), mean wave period Tm (Tm0,-1), mean wave period Tm01 (Tm0,1)and mean wave direction(Dm) for the 1979-2019. Additionally, flags advise caution where necessary when using the data. Flag_D is used for time steps when the wave and/or wind directions at the model boundary differ by more than 15 degrees between the CMIP6 data and the value determined from the downscaled wave database (DWDB). 20 degrees is maximum difference that wind and wave directions are allowed to differ, otherwise the timestep is set to NaN. Flag_S indicates possible inconsistencies between adjacent time series locations, caused by either the use of different offshore CMIP6 locations in the alongshore directions, or by a switch from one numerical model domain to another. Additionally, values for which the difference in Hs is greater than 0.15 m are flagged to inform the user of this difference. Flags are set for differences greater than 0.20 m (Flag_Hs020), 0.25 m (Flag_Hs025), 0.50 m (Flag_Hs050), 0.75 m (Flag_Hs075) and 1 m (Flag_Hs100). For all flags, 1 indicates this condition is true and 0 that it is not true. Transect IDs are associated with each location and are named in the following scheme: [A1A2A3_N1_N2], where [A1A2A3_N1_N2] is a unique ID for each transects that corresponds to the wave parameter output in the file. A1 is an identifier for the type of transect exposure (E for exposed transects, or S, sheltered, describing transects along Bays and Lagoons). A2 can be either E (east), C (central), or W (west), describing the general location in A3, which is abbreviated by either B (Beaufort Sea) or C (Chukchi Sea). N1 is a numerical baseline ID, and N2 the numerical transect order, starting from the Canada border. For files which include ‘BeringStrait_to_NortonSound’ in their file name, the ID consists only of [A1_N1_N2] where A1 is NSD. File names reflect the geographic area, the time period and the isobath for which the files contain data. For example, WaveTimeSeries_CMIP6_fut_KotzebueSound_to_BeringStrait_10mDepth.nc contains data for locations from Kotzebue Sound to the Bering Strait (also see browse graphic) for the future (202-2050) period along the 10 m isobath. Note that not every transect necessarily contains unique wave data. Due to the grid resolution, output location along the isobaths might overlap.
