Narrative:

GPWS was triggered at about 1000 ft AGL on approach to runway 28L at pit. We were on the localizer GS with gear down and flaps 15 degrees. We went around as per SOP and declared a missed approach to the tower. We were IMC at the time of the 'whoop, whoop.' tower vectored us around to another approach to runway 28L. Did the same approach, but stayed about 1/2 DOT high on the GS, broke out at about 800 ft AGL and landed normally.
