"Impact of dry intrusion events on the composition and mixing state of particles during the winter Aerosol and Cloud Experiment in the Eastern North Atlantic (ACE-ENA)."

Science
Figure 1. Representative carbon speciation map of a subset of particles collected during dry intrusion event. From journal.
The paper presents detailed chemical imaging of individual atmospheric particles collected over the Azores during long-range transport events.
Impact
Observations indicate that entrainment of particles from long-range continental sources alters the mixing state population and cloud condensation properties of aerosol in the region.
Summary
The work provides field observation data to inform atmospheric models that simulate sources and particle composition in the eastern North Atlantic.
