Traffic count

UTC · 1-minute buckets · Occ: distinct aircraft observed inside the volume during each minute. E/H: recorded entries during the current minute and the previous 59 minutes, using available logs. Missing minutes between two recorded values use their rounded average. Periods without observations on both sides remain empty. An aircraft first seen inside a sector has unknown entry time and is not counted as an entry.

Source: recorded IFR positions, retained for 7 days. Counts use the current volume definitions and capacities. Airport volumes count observed takeoffs/landings in E/H; they have no occupancy area.
