AIR MAIL

Where today’s air came from

The air arriving over Hopkinton about 5,000 feet above the ground was over the western Atlantic three days ago, about 1,620 miles back along its path. The nine paths traced from around the city fan out, so treat that as a best guess. It rose from near the ground on the way. Near the ground the air came from Canada; at 10,000 feet, from Quebec. Traced back 72 hours through NOAA’s hourly RAP analyses and the GFS beyond them, nine paths at each of three heights.
