Project 12 - Climate

The direct impact of aviation on climate via the emission of greenhouse gases and particles is small relative to other anthropogenic sources. However, the potential impact of aviation on climate is unique because aviation associated sources occur at high altitudes where other anthropogenic sources are absent, and aircraft are the only major source of emissions above the Arctic Circle. The climatic and chemical impact of aviation emissions and the resulting contrails and contrail-enhanced cirrus in the troposphere and stratosphere may be significant. There are large uncertainties in relating aviation emissions to changes in radiative forcing or surface temperature, especially for contrail-associated pathways. The research seeks to find robust relationships between aircraft emissions and the properties of contrails generated by aircraft under a variety of atmospheric conditions using both a high-resolution large-eddy simulation model and telescoping global-regional climate model.
