Due to wake turbulence, aircraft operating in the terminal area must maintain minimum separations on instrument approaches. This can be a significant constraint on the airport arrival rate. NASA's Aircraft Vortex Spacing System (AVOSS) project was undertaken to develop the technology to dynamically change aircraft arrival separations based upon atmospheric conditions and an understanding of vortex behavior. As part of this effort, a collection of meteorological sensor systems were deployed by Lincoln Laboratory and NASA at the Dallas/Fort Worth International Airport (DFW). These sensors, along with existing FAA and NWS systems, are used to create profiles of the atmosphere at the DFW airport. Scientific concept prototypes of the AVOSS was operated at Dallas/Ft. Worth in the summer of 1997-2000. The greatest challenge in preparing a single atmospheric profile for the wake vortex behavior models is merging data from sensors yielding different measurements of the same atmosphere. To meet this challenge, the AVOSS Winds Analysis System (AWAS) was developed to perform the data quality editing and fusion of sensor data.
