Abstract. We present and discuss a new dataset of gridded emissions covering the historical period (1850–2000) in decadal increments at horizontal resolution 0.5° latitude longitude. The primary purpose this inventory is to provide consistent reactive gases aerosols for use chemistry model simulations needed by climate models Climate Model Intercomparison Program #5 (CMIP5) support Intergovernmental Panel on Change (IPCC) Fifth Assessment report (AR5). Our best estimate year 2000 represents...

This study describes the methodology and results for calculating future global aviation emissions of carbon dioxide oxides nitrogen from air traffic under four IPCC/SRES (Intergovernmental Panel on Climate Change/Special Report Emissions Scenarios) marker scenarios: A1B, A2, B1, B2. In addition, a mitigation scenario has been calculated B1 scenario, requiring rapid significant technology development transition. A model aircraft movements (FAST) was used to calculate fuel use 2050 with...

Abstract Aviation emissions of nitrogen oxides (NO x ) alter the composition atmosphere, perturbing greenhouse gases ozone and methane, resulting in positive negative radiative forcing effects, respectively. In 1981, International Civil Organization adopted a first certification standard for regulation aircraft engine NO with subsequent increases stringency 1992, 1998, 2004 2010 to offset growth environmental impact air transport, main motivation being improve local quality assumed...

Aviation is seeking for ways to reduce its climate impact caused by CO2 emissions and non-CO2 effects. Operational measures which change overall flight altitude have the potential of individual effects, comprising but in particular We study changes altitude, specifically aircraft flying 2000 feet higher lower, with a set global models chemistry-transport, chemistry-climate general circulation integrating distinct aviation emission inventories representing such alternative altitudes,...

The atmospheric impact of aircraft NOx emissions are studied using updated inventories for the year 2006, in order to estimate photochemistry-related mitigation potential shifting cruise altitudes higher or lower by 2000 ft. Applying three chemistry-transport models (CTM) and two climate-chemistry (CCM) CTM mode, all including detailed tropospheric stratospheric chemistry, we short-lived radiative forcing (RF) from O3 range between 16.4 23.5 mW m−2, with a mean value 19.5 m−2. Including...

Comprehensive assessment of the environmental aspects flight movements is increasing interest to aviation sector as a potential input for developing sustainable strategies that consider climate impact, air quality and noise issues simultaneously. However, comprehensive assessments all three do not yet exist are in particular operational practice planning. The purpose this study present methodology which allows establish multi-criteria impact directly planning process. method expands concept...

Abstract. Aviation emissions are unique from other transportation emissions, e.g., road and shipping, in that they occur at higher altitudes as well the surface. of carbon dioxide, soot, water vapor have direct radiative impacts on Earth's climate system while nitrogen oxides (NOx), sulfur oxides, monoxide (CO), hydrocarbons (HC) impact air quality through their effects ozone, methane, clouds. The most accurate estimates aviation utilize three-dimensional chemistry-climate models gridded...

Black carbon (BC) emissions from aircraft engines lead to an increase in the atmospheric burden of fine particulate matter (PM2.5). Exposure PM2.5 sources, including aviation, is associated with increased risk premature mortality, and BC suspended atmosphere has a warming impact on climate. particles emitted also serve as nuclei for contrail ice particles, which are major component aviation's climate impact. To facilitate evaluation these impacts, we have developed method estimate mass...
