I'm looking for historical, daily locations of the North Atlantic Track (NAT, published daily as NOTAM) system for the past 10/20 years. I've already contacted what feels like dozens of organizations (FAA, Gander, Shanwick, ...) but no-one seems to actually archive the NAT locations.

I'd be extremely grateful for any pointers towards possibilities to acquire these data, be it free or paying.

  • $\begingroup$ @D_S thanks for the pointer; however, I cannot seem to be able to find NAT advisories using their search form ... $\endgroup$
