Aircraft Greenhouse Gas Emissions during the Landing and Takeoff Cycle at Bay Area Airports
<p>The aviation industry is a growing industry and has global environmental impacts. Throughout all phases of air transit, pollutant emissions, including greenhouse gases (GHGs), are released. The goal of this study is to quantify and characterize these emissions produced from aircraft in the LTO …

Conceptual aircraft design for environmental impact : modeling operations for emissions assessment
Decisions that guide technology investment and policy-making for the future of air transportation will be based in part on the tradeoffs between environmental performance and economics. The Environmental Design Space (EDS) project explores the tradeoffs between noise, emissions, and economics for …

The air quality and health impacts of aviation in Asia
… in Asia by modeling the air quality in Asia and applying Concentration-Response Functions (CRFs) to the aviation-attributable PM2.5 perturbations. In order to quantify the perturbation to the ambient air quality due to aviation emissions, the Community Multiscale Air Quality (CMAQ) model---a …

Development of a rapid global aircraft emissions estimation tool with uncertainty quantification
… changing the radiative balance of the atmosphere and impact human health by adversely affecting air quality. Many tools used to quantify aircraft emissions are not open source and in most cases are computationally expensive. This limits their usefulness for studies that require rapid simulation, …

Assessment of a new metric system to regulate NOₓ aircraft emissions at cruise
… NOₓ emissions cause an increase of surface PM2.5 and O3 concentrations that adversely affect human health. This public health consideration has motivated the International Civil Aviation (ICAO) Committe on Aviation and Environment Protection (CAEP) to set standards aimed at constraining NOₓ …

Benefit-cost assessment of aviation environmental policies
… management tool (APMT), only consider climate and air quality impacts derived from aircraft emissions within the US. In addition, only landing and takeoff (LTO) emissions are considered. Barrett et al., however, has shown that aircraft cruise emissions have a significant impact on ground-level …

A neural relevance model for feature extraction from hyperspectral images, and its application in the wavelet domain
… Of recent interest is the identification of landmasses which can support the landing and takeoff of fixed wing and rotary aircraft where accurate classification of the surface cover is of utmost importance. In a supervised classification scenario, a natural question is whether a subset of the …
