🌱💦New insights into carbon–water coupling in dryland ecosystems: We quantified how soil moisture and temperature regulate respiration across Australia, revealing nonlinear responses. This marks the final publication of Eva-Marie Metz’s PhD: shorturl.at/Gq10h Eva, its been a pleasure☀️ All the best!

WMO’s GAW programme put together guidelines to help cities better measure and track their greenhouse gas emissions. Proud to have contributed as a chapter lead author to this global community effort. Guidelines: doi.org/10.59327/WMO... #climateactionscience #urbanemissions

New paper: 🌇 Combining column and in-situ observations helps reduce uncertainties in urban CH₄ emissions and better capture trends. Thanks Jun and all coauthors for the great teamwork! doi.org/10.1029/2025...

Our Institute of Environmental Phyiscs hosted the ITMS (Integrated Greenhouse Gas Monitoring System) General Assembly 2025. Day 1 was a great start! Inspiring keynotes and new insights into modelling results. Huge thanks to all presenters & attendees for good discussions! @uniheidelberg.bsky.social

✨ New paper! ✨ We ran WRF at 1 km over an urban area to test how physics schemes shape performance 🏙️ Urban & PBL schemes matter most 🌁 Station characteristics often dominate metrics Why it matters: Better models = better GHG monitoring doi.org/10.1016/j.at... 👏 Kudos to Lukas Pilz

🙌🏻 New paper in Earth System Dynamics showing how social norms & group structures shape (un)sustainable futures. 🤝 Congrats to Max Bechthold on his first first-author pub + for leading a great interdisciplinary collaboration. 👉Paper: doi.org/10.5194/esd-...

Exciting news: Our pyVPRM paper led by @theogl.bsky.social has been published in GMD. The flexible further development of VPRM works with Sentinel‑2, MODIS & VIIRS and delivers high‑resolution and improved carbon flux estimates. Read it: doi.org/10.5194/gmd-18-4713-2025

🦄 The UNICORN CO₂ network is growing! 🚨 Red dots = installed sensors Blue dots = confirmed locations coming soon 🌍 We’re building an urban network in Heidelberg and Mannheim of atmospheric CO₂ - one node at a time. Stay tuned… the first data is coming in soon! 📊✨

🌍 Excited to share an important piece of work led by Jeongmin Yun on African carbon dynamics. 🛰️ Using multiple satellite data products (including OCO-2), we explore what drives interannual variability across Africa’s diverse ecosystems. 🌿 Check it out here: doi.org/10.1029/2025...

🦄 Meet the UNICORN Team: Prof. Dr. André Butz 
@abutz.bsky.social leads UNICORN with a focus on spectroscopic techniques and novel instruments. André fosters collaborative research across disciplines. 🌐 www.iup.uni- heidelberg.de/en/research/atmosphere/atmosphere-and-remote-sensing-butz-group

Visited Wageningen University for Kims PhD defense. The campus was beautiful, the discussions with bright students were inspiring, and Kim gave a fantastic defense of an impressive thesis. Thanks so much for the invitation and warm welcome! 😊

🦄 Meet the UNICORN Team: Dr. Sanam Vardag @sanamnv.bsky.social leads the UNICORN team with expertise in greenhouse gas simulations and urban emission quantification. She is driven by a commitment to interdisciplinary collaboration for climate solutions. 🌐 www.iup.uni-heidelberg.de/en/research/...

We’ve launched UNICORN – the University Network for CO₂ in the Rhine-Neckar Metropolitan Area 🌍🌆   UNICORN establishes a dense, urban CO₂ monitoring network to support science-based climate policy at the city scale.   🔗 Website: www.iup.uni-heidelberg.de/en/research/...   @uniheidelberg.bsky.social

Today I gave a remote talk at IWGGMS-21 on studying semi-arid regions with GOSAT 🌍 Really enjoyed many great talks—though couldn’t catch them all due to the time shift. Grateful to be part of this community! #IWGGMS #GOSAT #RemoteSensing #NIES

🌍 Excited for our group's work at #EGU25! From GHG sensing to AI-driven emission estimates & climate feedbacks. 🚀 Full list of contributions here: www.linkedin.com/posts/dr-san... #ClimateScience #GHG #RemoteSensing

New study uses satellite CO₂ data to reveal what drives seasonal carbon fluxes in South American temperate ecosystems. Turns out, rewetting dry soils spikes respiration before plants start photosynthesizing. A key process global models are missing. #CarbonCycle #RemoteSensing doi.org/10.1029/2024...

The institute of environmental physics participated at the Girls Day 2025 to show girls how cool environmental physics can be and to motivate this career path www.iup.uni-heidelberg.de/en/node/552 #girlsday #empowerment #girlspower @uniheidelberg.bsky.social

Quantifying urban emissions is difficult due to high heterogeny of anthropogenic and biogenic emissions in cities. @sanamnv.bsky.social presents experimental urban network designs and emission quantification for enhanced emission verification. #UrbanGHGSummit #ICOSCities

It was a pleasure to host a workshop on atmospheric modelling within the ITMS project (“Integrated Greenhouse gas monitoring system for Germany”) project. I enjoyed fruitful discussions on how to best track Germany's greenhouse gas emissions. #ITMS #Heidelberg @uniheidelberg.bsky.social

🌍 New research on the southern African carbon cycle! 🛰️ We used satellite CO₂ data (2009–2018) to refine CO₂ flux estimates, revealing that photosynthesis drives interannual variability, while soil respiration after rewetting shapes the seasonal cycle. 📄 Read more: doi.org/10.5194/bg-2...

I am excited to share that I have been appointed by the Federal Minister for Digital and Transport Affairs, Dr. Volker Wissing, as a member of the scientific advisory board of the German meteorological service (DWD). www.iup.uni-heidelberg.de/en/about-us/... @uniheidelberg.bsky.social

Hello Bluesky-World! I just deleted my X account and I am ready to start a network on Bluesky.
