Have you explored the 2025 European Air Quality Assessment from #CopernicusAtmosphere? As emissions fell, air quality trends improved, yet PM2.5 & ozone episodes persisted, linked to winter cold spells, summer heatwaves, Saharan dust & severe wildfires on the Iberian Peninsula. @ecmwf.int ⬇️

What are dendrometers and why do we need a global dendrometer network? 💥Our first GDN paper is out! We document how it all started with a meeting in Norway, and outline some of the great potential that lies in creating a global community. Read: doi.org/10.1093/tree... Join: globaldendro.org

📂 New data alert! Final quality-controlled Level 2 Atmosphere data is out: hourly greenhouse gas measurements from 41 ICOS stations across Europe, now covering right up to 1 April 2026. 🔗 https://www.icos-cp.eu/news-and-events/news/level-2-atmosphere-data-released

Out in the field at the ICOS Hyltemossa station at a hot summer day: Theodora (our intern from Greece) assisting Matilda with methane measurements using stem chambers. A spruce tree, a ladder and climate science in action. Stay tuned for the results! @beccsweden.bsky.social

Another intake up! Hopefully we'll soon have BVOC/CH4/CO2 EC Flux, CO2/CH4/O3 profile & subcanopy CO2 EC & CO2/CH4 soil/trunk chamber measurements. Note the @icos-ri.eu 30m CO2 EC Flux & 150m GHG profile setup in the background @icossweden.bsky.social @beccsweden.bsky.social @lufluxes.bsky.social

And another day enjoying the sun above the canopy! Getting our BVOC Eddy covariance system ready for summer. @icossweden.bsky.social @lufluxes.bsky.social @lund-university.bsky.social @beccsweden.bsky.social

Who needs a beach if you have a mast and can take a sunbath above the canopy? Did some maintenance on the #ICOS Flux system while we were up there. @icossweden.bsky.social @icos-ri.eu @fluxnet.bsky.social @lufluxes.bsky.social @beccsweden.bsky.social @lund-university.bsky.social

How do extreme events affect economies across Europe? In the #ACCREU project, researchers examined both direct damages and their wider impacts on supply chains and interconnected economies. PIK's Jan Hassel explains. 👇 youtube.com/watch?v=yBFG... (Video produced in collaboration with CMCC.)

Another heat wave is hitting Europe. June started hot & will continue to be so. While not as scorching hot here in Southern Sweden the average temperature has increased rapidly in the last 20 years, seen in the climate stripes for CPH. #showyourstripes @edhawkins.org showyourstripes.info

Extreme Temperatures Around the World@extremetemps.bsky.social · 2mo ago

It's hard to fathom what Europe will live next week. Thousands of records will be brutalized in Spain,France,UK,Benelux,Germany,Swiss,Austria and than the East Paris might record 4 consecutive days 40C UK will ridiculize its June national record Germany 10 days 37C+ This is CRAZY

Making your plans for ICOS Science Conference 2026? Why not join an excursion after the conference ends! Options include a visit to @hyltemossa.bsky.social and a meet & greet event at ICOS Carbon Portal. Read more: www.icos-cp.eu/news-and-eve... #ICOS2026SC

A recent study addresses the long-standing energy balance closure problem within ecosystem flux measurements 🌳 By using datasets from ICOS and NEON, the study shows that a substantial part of this energy imbalance is caused by incomplete energy accounting. Read more: www.icos-cp.eu/news-and-eve...

Exiting stuff happening in Hyltemossa. First ever point cloud of our mast! Joke aside, Langning Huo & her team are monitoring the forest for early signs of stress. Read more in the post by @remote-sensing-slu.bsky.social A closer collaboration is in prep, so stay tuned. @icossweden.bsky.social

"With this system, we can see forest stress before it becomes visible to the human eye—sometimes weeks to months earlier", says Langning Huo when describing the co-aligned VNIR–SWIR–LiDAR hyperspectral drone system can be used for advanced forest stress detection www.slu.se/en/news/2025...

This year we have again 3 interns learning about #ICOS measurements & helping out in various projects. Below Theodora (Greece) is helping with soil sampling & tree trunk chamber measurement for @lufluxes.bsky.social and Clara & Clémence (France) monitor phenology for @remote-sensing-slu.bsky.social

In May 2026, Europe experienced a rapid climate transition from cooler-than-average conditions to an unusually early & intense heatwave. France, UK, Ireland, Portugal saw their highest May temperatures on record, according to Copernicus Climate Change Service’s latest bulletin: http://bit.ly/4ek0T1L

A busy week! Erica & Anders took soil samples. Matilda & Stig measured CH4, CO2, N2O from stem chambers. Great opportunity for our new intern Theodora, from Greece, to take part in different activities besides seeing our #ICOS measurements @icossweden.bsky.social @lufluxes.bsky.social @icos-ri.eu
