Project Number: 013 COMPLETE
Category: Alternative Fuels, Emissions
This project uses computer models to simulate the short- and long-term evolution of aircraft exhaust aerosol and contrail particles and gases. Researchers are using data from NASA’S Alternative Fuel Effects on Contrails and Cruise Emissions (ACCESS 2) field experiment to initialize the model and compare its results to the outcomes of real-world tests, including national and international emissions data. The experiment is designed to measure exhaust composition and contrail characteristics, as aircraft burn different types of fuel with varied engine thrust settings.
