Nice change of scenery during today's excursion to "Tavastland", currently docked in Landskrona. Thanks Madeleine for showing & explaining the ferry box setup. Measurements by #SMHI as part of @icossweden.bsky.social & data from other ships of opportunity contribute to the @icos-ri.eu Ocean Domain.

Inspiring presentations today at our annual Perennial workshop! Huge thanks to our PhD students Veronika and Anna for sharing their research, and to Kernza experts Tim and Doug for their deep insights into perennial grain agriculture.

The 2026 FLUXNET Secondment Program is open for applications!

The program supports extended visits of 2 - 6 weeks for early career scientists based in U.S. institutions to an international host institution to conduct research with eddy covariance data.

Our highly international Perennial team have met up in southern Sweden for a tour of sites growing the perennial wheat #Kernza (including our eddy covariance site in Alnarp) to start off a three day workshop

Forest inventory underway at our continuous cover forestry site, aimed at characterizing stand structure, growth dynamics and management outcomes. A key challenge involves quantifying natural regeneration by counting seedlings and saplings

Anna has spent a few days taking soil and root samples down to 2 m depth in our perennial wheat field. Hard work but she's has good help from Jonas and Ryan from SITES Lönnstorp... and from the Wintex soil corer

... endless cable meters for a side by side PAR sensor comparison. 20 sensors from the below canopy setup, 2 from the mast, 8 spare & on top 35 extra for a fPAR comparison between @icos-ri.eu & @copernicusecmwf.bsky.social GBOV within #NUBICOS

Great fieldwork days with our new batch of Master students, here at at our agricultural site. During these days, they have set up their own eddy covariance tower and practiced flux measurements using chambers, among other things.

Campbell CPEC310 EC tower set up 50 m away from our permanent flux tower investigating climate benefits of perennial crops compared to normal crop rotation. Great work by our students!

This summer @alindroth.bsky.social worked hard to set up soil & trunk CO2/CH4 chambers around our subcanopy EC system. Mikhail Mastepanov, designer & builder of the soil chambers, helped set up Ander's latest trunk chamber design yesterday.

Last week Linda & Johannes from @gfz.bsky.social visited to scan the forest around the @icos-ri.eu EC flux mast with a LIDAR drone. All went well, so they scanned the young stand at the @lufluxes.bsky.social EC mast too.

Today it was time for the second annual harvest of our perennial wheat #kernza. Perfect harvest weather and it seems like both grain and straw yield will be significantly higher than the first year.

Soon time for harvest at our #Kernza site in Alnarp,Southern Sweden. Exited to analyze 2 years of perennial crop EC flux measurements & compare the C balance to conventional crops (1 year rape seed & 1 year winter wheat).

Tobias and Peter adjusted the flux system height following harvest of the winter wheat, cleaned all sensors and cameras etc.

Nice cloud formation seen from the Hyltemossa.bsky.social tower yesterday!

We were lucky and all the rain and thunderstorms passed us, while it was calm and sunny.

First round of N2O flux measurements from ley (and more crops/treatments) in our new project is underway.

Minutes before the rain hit the Eddy covariance tower in Dahra, Senegal.

From Swedish forest to Savannah, fun to swap @hyltemossa.bsky.social for some days to help Aleksander with the GHG gradient setup & maintaining the EC system run by Torbern
@lufluxes.bsky.social @lunduniversity.bsky.social
lufluxes.bsky.social
Maintenance in full swing at the Dahra site, with Osman and Tobias as tower crew and Aleksander on the ground. Check and cleaning of the EC gas analyzer done and filters in the profile system swapped. So far all went smoothly.

While a heatwave is pounding Europe some of us got away to enjoy surprisingly slightly cooler weather in Senegal. 31 C only but very humid since it's the beginning of the rain season. Still pretty dry and bare in the the footprint of the Dahra EC tower though.

We managed to pick the hottest day of the year for installations of collars for N2O chamber measurements in agricultural trials at SITES Lönnstorp. Still relative cool compared to southern Europe these days...
