\f0\fs24 \cf0 This dataset contains SWIFT data measured in the December 2019 experiment conducted in the NE Pacific, funded by NSF-OCE 1756040. These data were used in the manuscript \'93Rapid deterministic wave prediction using a sparse array of buoys\'94 published in Ocean Engineering (2021). Additional SWIFT data is available at swiftserver.apl.washington.edu. This data and code is provided without warranty.\

Each .nc file contains processed SWIFT data collected in December 2019 field experiment. Raw wave time series have been linearly interpolated to a common time base based on the coarsest sampling frequency used in each contemporaneous burst. Missing values have been replaced with NaN. File naming convention indicates day and time of deployment: \
swiftdata_(year)(month)(day)UTC(hr)(mn).nc\
\
\
Variable definitions:\
\
time: UTC time stamp of contemporaneous records in MATLAB datum format\
geo_x, geo_y: local Cartesian coordinates\
lon,lat: Earth geodetic coordinates\
swift_id: SWIFT serial number\
nu: scalar bandwidth\
Tp: peak wave period in seconds\
driftspd: buoy drift speed [m/s]\
driftdirT: buoy drift direction [degrees from true North]\
z: surface displacement measurements\
u: surface east velocity measurements\
v: surface north velocity measurements\
spec_f: frequency vector used in directional wave spectrum [Hz]\
spec_theta: directional bins used in wave spectrum [degrees]\
spec_Etheta: Directional wave spectrum averaged over previous hour of data [m^2 s^-1 deg-^1]\
forecast_buoy_id: Serial number of down-wave target buoy omitted from reconstruction.\
