Both jackets are actually modifications of the Atlantis season 4/5 jackets. The ridiculous centre pleat from the back of the Atlantis jackets is gone, the back of Tamara's jacket is totally plain. I don't have a pic of the back at the moment but there's a few times you can see the back in some of the episodes. The fabric has reverted back to black ripstop as was used throughout SG-1.
If you zoom in you can see the telltale squares.
This pic shows how the pattern is the same, even down to the decorative topstitching on the front seams. (Apologies on the size of the pic.)

I'm part way through sewing this jacket using Simplicity pattern 3628 as suggested by Mozzie and Starfire Phoenix for the female SGA jackets. Fortunately ripstop in black is now available at Spotlight after an absence of some time. The only changes I've identified are the pocket flaps on the front, which I suspect are false pockets, the epaulets, and the pocket on the sleeve. Fortunately Tamara's uniform is plain on the back, so there's no further modification required there.
The men's jackets on the other hand, although doing away with the centre pleat, now have bifold pleats at the shoulders, just like the WEP style from SG-1 as can be seen here...

Not quite sure how I'll tackle that when I decide to do a male uniform.
