Data are organised in four files: EUArr.npy, EUDep.npy, USArr.npy, and USDep.npy. The file name encodes the region and the type of delays (arrival and departure). Each file is a standard NumPy array, that can be opened with the corresponding Python library. It contains a single four-dimensional tensor of size 30 x 100 x d x 24, the four dimensions respectively represent the 30 airports of the region, the 100 independent realisations of the generation process, the d days available for each region (610 for EU and 1,825 for US), and the 24 hours of the day.

Synthetic time series of hourly delays, in 30 airports in Europe and US.
