Measurement of Emissions

Project Category: 
Emissions
Project Number: 
9

Project 9's objectives were to characterize the emissions (both small particles and condensable gaseous species) from aircraft and airports through measurements, understand and model the microphysical processes associated with particle formation, and determine the health effects of emissions.

Outcomes

Database of PM & HAPS emissions from aircraft, along with plume models.

Aviation particulate matter emissions research, previously known as UNA-UNA (Un-named Airline - Un-named Airport)) Study. There were two components to this study – a dedicated engine test and an airport study where advected plumes were sampled from commercial transports during normal airport operations. This report describes both measurement activities, and shows the tremendous promise for a fresh perspective on the magnitude and nature of aviation emissions under real-world conditions, the analysis and interpretation of which was greatly informed by the dedicated engine tests.
