A comprehensive study by He et al. (2026) reveals that the choice of tree species in urban greening programs plays a critical role in shaping urban air quality, particularly ground-level ozone pollution. Key Findings Dominance…
In November, a meeting was held in Innsbruck between the partners of the Interreg Italy-Austria Breathing project, which is coordinated by Arpav. Breathing Team November 2025
VOCentinel at IAO: A New Era of Continuous VOC Monitoring In summer 2025, a prototype of IONICON’s new VOCentinel was successfully deployed at the IAO of the University of Innsbruck, where it is now carrying…
Longterm urban eddy covariance observations of methane and other trace gases reveal characteristic anthropogenic emission hotspots Extended Poster EGU25-5202 Synopsis: Long-term urban eddy covariance observations of methane, CO2 and other trace gases allow to constrain…
Mapping CH4 in urban areas is still challenging because emissions are often diffuse. A new study https://doi.org/10.1016/j.atmosenv.2024.120743 finds evidence of urban superemitters that can substantially incrase emissions.
A recent paper by Pfannerstil highlights the potential of airborne eddy flux measurements (Temperature-dependent emissions dominate aerosol and ozone formation in Los Angeles | Science). They show that up to 60% of the VOC reactivity…
We are proud to be part of the new FWF funded project on the future of mountain forests under a drier climate. The Future of Mountain Forests – Universität Innsbruck (uibk.ac.at) Mountain regions are especially…
The fraction of ozone near the surface in urban areas tends to be overestimated in atmospheric models. New observations at the IAO reveal a possible explanation, which is presented in the following paper https://www.science.org/doi/10.1126/sciadv.add2365 Short…
Entering our 6th year of #urban #CO2 flux observations. We will start posting flux data on http://www.europe-fluxdata.eu/ So far we have collected 5 years of CO2 (H2O), heat, momentum and NOx fluxes, 3+ years of…
The paper by Nicolini et al., shows the variability and reduction potential of CO2 emissions across Europe. Data show first measured evidence of a consistent reduction of CO2 emissions, proportional to the stringency of restrictions.…
