AIR MAIL

Where today’s air came from

The air arriving over Northfield about 5,000 feet above the ground was over the North Atlantic three days ago, and over the western Atlantic a day ago, about 1,310 miles back along its path. Most of the nine paths traced from around the city agree. 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.
