PhD Position in Atmospheric Chemistry The Atmospheric Chemistry group at the Institute for Atmospheric and Climate Science (IAC) – ETH Zurich invites applications for a 4-year PhD position on “Exploring the lifecycle and climate effects of absorbing aerosol from fires”. Project background The Atmospheric Chemistry group at ETH conducts research exploring the processes controlling tropospheric composition (gases and particles) and their intersection with global change. Research makes extensive use of global modeling tools (GEOS-Chem and CESM) and analysis of large observational datasets. In many regions of the world, wildfire frequency and extent are increasing, driven by climate change. These fires emit a range of gas and particle phase compounds. These include absorbing organic aerosol, so called brown carbon (BrC). Fires also emit gas-phase compounds that can chemically transform to form absorbing BrC particles. The lifecycle and characteristics of atmospheric BrC are highly un
