Abstract

"The UMR Mobile Aerosol Sampling System (MASS) has measured the particulate matter (PM) emissions from commercial aircrafts during the routine takeoff operation within 100m of a runway and 200m of a taxiway at a major US airport for two days in September 2004. The emissions were measured with Is time resolution using a differential mobility spectrometer (DMS500). The plumes were measured for 2 days, from over 400 commercial aircrafts, ranging from 717’s, 767’s, MD-88’s, to Turboprop’s. The wind field was most of the times favoring, allowing the runway plumes to be detected downwind by the sampling system. The departure timings and the corresponding aircraft details (ref: 049 27 28 29 - Aircrafts.xls) and the ambient atmospheric conditions which include the wind direction, velocity, relative humidity and temperature were recorded. The ambient conditions were recorded every minute during this period, (ref: AmbSep282004.xls, AmbSep292004.xls).

In order to interpret these PM data it is important to be able to uniquely identify a given aircraft with a specific emission plume. As is common at many airports departure frequency varies throughout the day. At high departure frequencies, the data gathered cannot be attributed to any specific single aircraft since the emission plumes arriving at the sampling system are convoluted by overlapping departures and from upwind aircraft stopping and starting while taxiing forward in a line towards the number one departure slot.

The data presented here are “first of a kind” PM measurements of advective plumes from commercial aircraft. Although it is planned to eventually interpret high frequency departure data, in this thesis only low frequency departure data specifically attributable to given aircraft will be studied. The data interpretation arising from this thesis will provide the foundation for the more complex high frequency data analysis."--Abstract, page iii.
