“…Also related, multiple metrics of NAS performance have been used to cluster similar days [6]. Clustering spatiotemporal weather-impact scenarios to facilitate the weather-impact-scenario-driven strategic ATM decision support framework has also been recently studied [3,4,12]. Three distance measures were used to cluster spatiotemporal weather-impact scenarios [3]: 1) total capacity-based measure, which is calculated by summing capacities over all time points and sectors for each scenario and using the total capability of each scenario to calculate pairwise scenario distances; 2) timeaggregated sector capacity-based measure, which is calculated by summing capacities over all time points for each sector and then using the 2-norm difference of the sector vector as pairwise scenario distances; and 3) single sector capacity-based measure, which is calculated by selecting an important sector to represent each scenario and using the 2-norm difference of its time vector as pairwise scenario distances.…”

“…These two-element vectors are then used to compute the pairwise scenario distances based on their Euclidean distances. It was noted that summing weather-impact intensities along one dimension does not retain the spatial topology or temporal sequence, and thus may cause problems such as the inability to differentiate time sequences with opposite ordering ("metric symmetry") [4].…”
