Narrative:
We were nearing the top of descent on our filed and cleared route that included the kooly RNAV STAR to phx. We expected and briefed the arrival for runway 25L. We then received a clearance to fly direct to squez and descend via the KOOLY4 for landing runway 25L. We set the MCP [altitude alert] to 4;000 ft for a managed descent. In the descent I realized that it was time for a new ATIS so I requested one through ACARS. Upon passing FL180 we set the altimeters to the just received ATIS altimeter setting (30.37). I am not certain of the exact sequence of the following events; but we received a clearance to delete the speeds on the arrival and change to runway 25R. This runway does not have an ILS; so we needed to spend some time determining what approach page matches the identifier in the FMGC; in this case I believe it was RNAV Y 25R. About this time we were crossing squez and the controller informed us ATIS was now tango and the new altimeter setting. We reset our altimeters; and I requested the new ATIS since we had sierra. After resetting to the new setting (30.03) we realized that this was a large difference. Soon the captain discovered that I had requested; received; and told him the altimeter for pdx and not phx. At this point we realized that we had likely crossed squez low.the rest of the flight was normal. The approach planning and briefing was conducted in a non hurried manner which included review of the notams and runway performance. The captain is conscientious and disciplined; and he creates an atmosphere in which I should be able to perform my best. In the future I will read the ATIS line by line to try to avoid making the same mistake.
Original NASA ASRS Text
Title: When the First Officer aboard the A320 inadvertently picked up the ATIS for PDX vice their destination; PHX; the altimeter thus obtained may have caused the flight to cross their active waypoint; SQUEZ below the required 15;000/12;000 FT window before they discovered their error.
