Charts from the AIGFS (Artificial Intelligence Global Forecast System) model are now becoming available on TWO. They're stepped at 6 hour intervals out to 384 hours ahead. The datasets appear to (currently) contain fewer variables than the GFS physics based operational model.

The charts below are from today's 00Z update, t+384

I've seen suggestions that AIGFS will be more accurate than ECM AIFS but can't confirm that is the case.

PS: Updates will be irregular for a couple of days.
