Atmospheric research in the heart of the Alps
We investigate atmospheric composition, surface exchange and transport by connecting advanced chemical measurements with micrometeorology and mountain meteorology.
We connect atmospheric chemistry with atmospheric physics in complex environments to understand why atmospheric composition changes where people and ecosystems meet.
Research
From molecular fingerprints to city-scale fluxes and atmospheric columns, our work is organised around four connected research areas.
We quantify urban emissions and investigate how chemistry, turbulence and Alpine topography shape pollutant concentrations.
Explore 02We study volatile compounds, carbon and water exchange, and the feedbacks linking vegetation stress to atmospheric chemistry.
Explore 03Ground-based spectroscopy links local observations with atmospheric columns, global networks and satellite products.
Explore 04High-frequency instruments, eddy covariance and open analysis workflows turn complex observations into defensible fluxes.
ExploreObservatory & laboratories
The Innsbruck Atmospheric Observatory is the central interface between long-term measurements, intensive campaigns, instruments, data products and collaboration.
National Facility · IAO InnsbruckEuropean research infrastructure
The Innsbruck Atmospheric Observatory connects its urban–Alpine site with the European research infrastructure for aerosols, clouds and trace gases.

Selected projects
Our projects connect long-term observations, field campaigns and method development across spatial and temporal scales.
Long-term and campaign measurements constrain NOx, CO₂, methane and VOC emissions above Innsbruck.
ExploreEddy-covariance observations investigate diffuse, vertically distributed post-meter emissions from the built environment.
ExploreA multidisciplinary FWF programme studies how drier conditions affect carbon, water, plant stress and ecosystem services.
