Narrative:
Arrived early in dtw terminal area from rno at XA40 local. We were #1 for approach. Approach control turned us in just outside revup OM. We were configured for landing but slightly high at revup. First officer was flying and did not descend quite fast enough to remain on GS. We suspected a slight tailwind might exist. At 900 ft AGL, received 1 'pullup' on GPWS and executed immediate missed approach. Received vectors for another approach and approach control confirmed some tailwind might exist. First officer conducted coupled approach to normal landing.
