Narrative:

At 800 AGL on approach to runway 16R at den the master warning lights illuminated followed immediately by 'windshear windshear windshear' being announced by the GPWS. In addition; windshear was illuminated on the captain's ADI. I immediately firewalled the throttles; double-clicked the go around switches; rotated towards 15 degrees nose up and performed the escape maneuver. On approach I had established a normal 700 foot per minute descent rate and upon initiation of the escape maneuver the descent rate was arrested; however for 2-3 seconds the aircraft did not climb despite full power and an approximately 15 degree nose up attitude. Shortly thereafter approach control announced a microburst alert. I continued the escape maneuver to 9000 MSL and the subsequent approach to 17R was uneventful.
