Alternative Fuel Effects on Contrails and Cruise Emissions Data Timeseries

Here’s another video from the ACCESS project showing what a running time series of the data from our instruments looks like as we move into and out of the DC-8’s engine exhaust plume. For the project, we had a large number of instruments inside the chase plane that measure aerosol and trace gas concentrations and properties. To make these measurements, we would pull air into the plane through a small, 1/4-inch forward-facing stainless steel tube that was mounted to the top of the aircraft (Crown-Mounted Sa
