Abstract This report addresses aspects of an extensive aircraft wake turbulence measurement program conducted at San Francisco International Airport (SFO) over a two-year period. Specifically, this report describes the sensors used for data collection and the resulting data sets that were used for analysis of the Simultaneous Offset Instrument Approach (SOIA) procedure proposed for use at SFO. Three anemometer Windlines were deployed perpendicular to and between Runways 28L and 28R to measure and record wake vortex motion between the runways near the threshold and touchdown regions. Because Runways 28L and 28R are used for 80% of SFO arrivals, the SFO wake turbulence Windline dataset, comprising approximately 250,000 arrivals, is the largest ever accumulated. Pulsed Lidar wake measurements were made for approximately one month at a location where aircraft were approximately 500 feet above San Francisco Bay (about 9,000 feet from the thresholds). The ambient wind at 20 feet above ground was monitored on either side of the two runways, and a wind Sodar was used to measure wind profiles up to a height of 656 feet. Automated Surface Observation System (ASOS) winds at 33 feet above ground were also obtained.
