ACCACIA (Aerosol Cloud Coupling And Climate Interactions in the Arctic):

Arctic climate change has accelerated in the last few decades culminating in the record summer sea-ice minima of 2012. The retreat of Arctic sea-ice and warming of the Arctic atmosphere will impact the global climate. However, significant gaps exist in our understanding of the Arctic climate system.

This research focuses on modelling the processes affecting Arctic aerosol properties and aerosol-cloud interactions using global models (www.ukca.ac.uk) and observations from the ACCACIA campaign.

ACCACIA is a aircraft and ship campaign taking place in the spring (Mar- Apr) and summer (July) of 2013. The overarching objective of this study is to reduce the large uncertainty in the effects of aerosols and clouds on the Arctic surface energy balance and climate. Further information about the campaign can be found in our blog:

Ice Nucleation:

Although typically observed at very low concentrations (<1/cc), ice nuclei (IN) have been shown to initiate ice formation in mix-phased clouds. Ice formation can strongly impact cloud radiative properties and plays a significant role in precipitation formation. However, mechanisms for ice nucleation on aerosol are poorly understood and thus, neglected in many climate models.

This project uses experimental data from the ice nucleation group at the University of Leeds in combination with global atmospheric models to develop parametrisations for different IN species and quantify global IN concentrations and impacts.
