Book Description
"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 1s 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 ... 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 up;wind 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"--Abstract, leaf iii.

Book Description
"TRB's Airport Cooperative Research Program (ACRP) Report 97: Measuring PM Emissions from Aircraft Auxiliary Power Units, Tires, and Brakes presents the results of a comprehensive test program designed to measure particulate matter (PM) emissions from auxiliary power units and from tires and brakes during the landing phase of operations of in-service commercial aircraft. The research results are designed to provide a significant contribution to the characterization of emissions from these sources with the goal of helping airports improve the accuracy of their PM emissions inventories."--Publisher's description.

Book Description
Analysis of total pollution emissions from USAF aircraft requires basic data such as aircraft engine pollution emission factors and landing and takeoff (LTO) time-in-modes. The report updates the list of measured pollution emission factors specific to each major USAF aircraft engine type. Results of original research to define USAF LTO cycle times for nine operational modes per aircraft type are presented.

Book Description
This thesis examines the impact of aircraft emissions on local air quality by performing two analyses: an assessment of U.S. commercial aircraft contribution to county budgets of primary pollutants in nonattainment areas, and an assessment of the health effects caused by commercial aircraft emissions that serve as precursors to changes in ozone and ambient particulate matter (PM). Based on 148 airports located in 134 counties, this work found that for the base year 2002, the commercial aircraft contribution to county budgets of primary pollutants of CO, NOx, SOx, VOCs, PM2.5, and PM10 ranged from less than 0.01% to as high as 36.36% with an average contribution of 0.82%. The average contribution for CO was found to be 0.81%, NOx 1.73%, SOx 1.39%, VOCs 0.67%, PM2.5 0.24%, and PM0o 0.07%. In general, this research found public health detriments resulting predominantly from PM2.5 related to aircraft emissions. However, the inventories used for the health impacts analysis are not consistent with the inventories that are described above and have several known errors. Therefore the results are presented only to illustrate the methodologies rather than as a good estimate of the health impacts. Notably, ozone disbenefits occurred with the removal of aircraft emissions of NOx. Urban cores experienced increased levels of ozone resulting in a net increase in incidences of ozone-related health endpoints. There are several limitations to the work described in this thesis. In particular, the inventories used for assessing the health impacts may be in error by as much as +50% and the air quality simulations were completed for only 4 months of the year. Therefore, the primary contribution of this thesis is in providing a description of the methodologies that will be used later within a more comprehensive study.
