MIT Lincoln Laboratory’s Aviation Weather Decision Support Laboratory introduces a range of advanced weather products and associated air traffic impact tools that are being developed to support the needs of the current and future aviation system. The lab is a venue to integrate relevant ATC operational data and to develop and refine decision support systems. The facility continuously assimilates and archives live air traffic and weather data from across the United States, including data streams from more than 150 NEXRAD radars, which are used to validate algorithm improvements to better detect hazardous winds, icing, or hail. Aviation weather algorithms and other technologies developed in this facility contribute to currently operating weather systems.
