A dataset of hourly sea surface temperature from drifting buoys [PDF]
Scientific Data, 2022 AbstractA dataset of sea surface temperature (SST) estimates is generated from the temperature observations of surface drifting buoys of NOAA’s Global Drifter Program. Estimates of SST at regular hourly time steps along drifter trajectories are obtained by fitting to observations a mathematical model representing simultaneously SST diurnal variability ...
