The key science objective involves understanding the evolution of linear contrail into cirrus clouds. We also seek to determine how this is influenced by background factors and how this evolution of contrail into cirrus interacts with the radiation field and ultimately has impact on climate.

Air travel and its associated emissions are growing faster than other sectors. These emissions are predicted to contribute a significant warming of climate over the coming century. One of aviation’s largest effects is likely to be that due to contrails and especially aviation induced cirrus, but these effects remain more-or-less unquantified (Forster et al., 2007). The two previous estimates have relied on correlating air traffic with cirrus coverage and have both large uncertainties and methodological problems. The ultimate aim of this proposal is, for the first time, to build a physically based parameterization of aviation induced cirrus to determine its role in climate change.

This campaign will aim to gather a diverse set of observations of different cloud types over land and ocean to trial a new 1D-Var code and develop techniques to allow the assimilation of cloud-affected radiances in the Met Office Unified Model for NWP.
