Mapping urban methane (CH4) emissions

Von Thomas Karl

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.

Mapping Urban Haze

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…

What is the future of mountain forests?

Ein interdisziplinäres FWF-Projekt untersucht, wie zunehmende Trockenheit Bergwälder und Atmosphäre–Ökosystem-Rückkopplungen verändert.

Half a decade of Trace Gas Flux Observations

Von Thomas Karl

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…
