A new dataset of sea surface temperature (SST) has been generated from the observations of the drifting buoys of NOAA's Global Drifter Program. Estimates of SST at regular hourly time steps along drifter trajectories are obtained using a novel approach which consists in fitting to observations a mathematical model representing simultaneously SST diurnal variability and SST low-frequency variability. Subsequent estimates of non-diurnal SST, diurnal SST anomalies, and total SST as their sum, are derived with their respective standard uncertainties. This Lagrangian SST dataset has been developed to match the existing hourly dataset of position and velocity from drifters, notably providing new opportunities to investigate upper-ocean processes controlling SST variability.
