AIR MAIL

Where today’s air came from

The air arriving over Brentwood about 5,000 feet above the ground was over the North Atlantic three days ago, and over the western Atlantic a day ago, about 1,290 miles back along its path. It rose from near the ground on the way. Near the ground the air came from Canada; at 10,000 feet, from New England. Traced back 72 hours through NOAA’s hourly RAP analyses and the GFS beyond them, nine paths at each of three heights.
