How important are local sources and long-range transport of aerosol particles for the IN and CCN concentration in the Arctic?

Poster

The appearance of IN and CCN in the Arctic and their vertical distribution is of importance for Arctic low-level mixed-phase clouds. We use a combination of field measurements and regional modeling to derive vertical IN/CCN profiles. The profiles are compared for a situation with predominantly locally emitted aerosol particles to a situation dominated by long-range transport of aerosol particles.

The Aerosol Society recognises the importance of our diverse community and believe that to produce the best quality science we must encourage a proactive and inclusive approach to equality. This can be achieved by developing and retaining a diverse range of talented people to achieve their full potential free from discrimination. We acknowledge our role in engaging with the wider aerosol science community to develop a fair and friendly environment by promoting equality, diversity and inclusion for all, recognising that we come from varying backgrounds and experiences.
