 ngvar Kamprad Chair Lecture: "Arctic Aerosols – Tiny drivers and tracers
  of climate change"\n\nAbstract\nThe Arctic is warming two to three times 
 faster than the global average\, a phenomenon called Arctic amplification.
  While some processes responsible for the amplified warming are well known
  (e.g.\, the snow and ice albedo feedback)\, there are several mechanisms 
 that remain poorly understood and unconstrained. Among those are the clima
 te-relevant effects of aerosols. Aerosols interact directly with solar rad
 iation through scattering and absorption. They also change the short- and 
 longwave radiative properties of clouds. Through both effects\, they direc
 tly affect Arctic surface temperatures. Sources of aerosols in the Arctic 
 are both anthropogenic and natural\, and there is a strong seasonality in 
 the aerosol amount and properties due to the complex Arctic meteorology an
 d cryosphere-ocean-atmosphere interactions. As the Arctic warms\, increase
 d anthropogenic activities introduce new emission sources within the regio
 n\, while distant\, but important\, mid-latitude sources have declined due
  to better air quality regulations. At the same time\, Arctic warming invo
 kes changes in natural sources of aerosols and their precursors\, making t
 he task of constraining their climate effects more complex and creating an
  urgency to translate these fundamental processes into numerical models to
  simulate future Arctic change.\n\nAbout the speaker\nJulia Schmale is ten
 ure track assistant professor at EPFL since 2019 heading the Extreme Envir
 onments Research Laboratory at ALPOLE at EPFL Valais Wallis. She holds a m
 aster degree in environmental engineering from the University of Leoben\, 
 Austria\, and obtained her PhD from the Max Planck Institute for Chemistry
  and Johannes Gutenberg University in Mainz\, Germany\, on the chemical co
 mposition of aerosols in the troposphere using aircraft-based mass spectro
 metry. Julia held a postdoc position at the Laboratory of Atmospheric Chem
 istry\, Paul Scherrer Institute\, Villigen\, Switzerland\, before becoming
  a group leader there. Starting from her PhD\, Julia dedicated her researc
 h to exploring the atmospheric chemical composition in polar and mountain 
 regions with a specific focus on interactions with the cryosphere\, ocean\
 , land\, biosphere and anthroposphere. Her work aims to understand how cli
 mate change drives and alters these interactions and which feedback loops 
 are to be expected. Her research has mainly been based on field studies in
  the Arctic\, Antarctic and central Asia. She has taken leading roles in t
 he Antarctic Circumnavigation and MOSAiC expeditions.  \nIn addition\, Ju
 lia has a strong interest in science-policy interactions\, which she pursu
 ed at the Institute for Advanced Sustainability Studies in Potsdam\, Germa
 ny on the topic of the energy - air pollution - climate change nexus. Amon
 gst other\, she is also a lead author of the Expert Group on Short-lived C
 limate Forcers of the Arctic Monitoring and Assessment Program and represe
 nts Switzerland in the International Arctic Science Committee Atmosphere W
 orking group.\n
