Aerosol-cloud interactions in the Arctic and how we can study them using short- and long-term in-situ observations
Lecturer: Paul Zieger
Associate Professor, Stockholm University & Bolin Centre for Climate Research
Within this overview talk, we will present recent observational studies from the Arctic that reveal how a diverse array of aerosol particles - including Aitken mode particles, black carbon, and primary biological aerosol particles (PBAP) - play critical roles in Arctic cloud formation. By synthesizing long-term measurements from Zeppelin Observatory on Svalbard along with in situ data from Arctic Ocean expeditions on board the I/B Oden, the results highlight clear seasonal patterns, as well as various distinct features of e.g. PBAP contributing to warm-temperature ice nucleating particle concentrations. Overall, our findings demonstrate that both natural sources (from marine and terrestrial biospheres) and anthropogenic influences (such as Arctic haze) significantly affect the properties of cloud condensation nuclei and mixed-phase clouds, ultimately impacting radiative forcing and climate projections.
