AIR MAIL

Where today’s air came from

The air arriving over Isle au Haut about 5,000 feet above the ground has hardly traveled: three days ago it was within 60 miles of here, drifting in light winds. It rose from near the ground on the way. Near the ground the air came from Canada; at 10,000 feet, from the western Atlantic. Traced back 72 hours through NOAA’s hourly RAP analyses and the GFS beyond them, nine paths at each of three heights.
