AIS dataset containing weather and ocean conditions

The AIS dataset is provided by the National Oceanic and Atmospheric Administration (NOAA), spanning from January 2020 to December 2020. The trajectories of 140 individual vessels (including tankers and cargo) were collected. Weather and ocean conditions for the same period are obtained from the National Data Buoy Center (NDBC), collected from 15 buoys. Noise points were removed, and the linear interpolation method was applied to address the irregular time intervals and the absent points.   Then the time series were resampled at one-minute time steps.   The buoys data had undergone outlier cleaning, linear interpolation, and resampling at one-minute time steps. The time series of weather and ocean conditions were constructed by assigning the nearest buoy to the vessels along its trajectory.
