Happy to see our paper published in @PNASNews today!! We show that tundra vegetation can substantially boost its volatile isoprene emissions in response to rising temperatures. A great collaboration with many colleagues @ERC_Research #TUVOLU @Riikka_Rinnan pnas.org/eprint/DJPWMAH…

We are looking for a PhD student! Do you want to analyze gas and particle urban pollution in Barcelona using real-time mass spectrometry? See link for further info 👇🏼

🌳🔥És possible un incendi com el de Los Angeles al @parcncollserola? L'alumnat de @EscolaPoveda ha mesurat les condicions d'humitat, llum, temperatura i flora per trobar-ne la resposta amb Albert Egea, Roger Seco i @natalimorenop de l'@IDAEA_CSIC per trobar-hi resposta

It would be great if you can replicate/adapt/improve our work for your own experiments!!

We also provide the list of commercial parts used for flow control, valve switching, and data recording.

🤔 Thinking of building a multi-enclosure system for biosphere-atmosphere gas exchange studies? Check out how we did it for the "Fluxtron" at the Guenther lab @uciess doi.org/10.1016/j.chem… 👇🏼

I would like to introduce our new paper in Nature Communications, which is the result of a highly successful international collaboration with @VOLT_center , @Riikka_Rinnan , @atzukac , @LundJing , @lejishvettikkat , and other great collaborators. We found that the sedges in the Arctic have a different temperature response curve compared to other known isoprene emitters, which explains the high temperature sensitivity of isoprene emission observed through whole-ecosystem flux measurements. By integrating our findings, the updated model predicted a 20% increase in isoprene emissions from the high-latitude regions in the Northern Hemisphere. We also found that the existing model had underestimated the long-term trend of isoprene emissions by 55% for high-latitude regions with Arctic warming nature.com/articles/s4146….

Last week I gave 2 talks to students: 1️⃣ @INSCelesBellera middle schoolers (13-year-olds) about air pollution caused by automobiles 🚙💨 2️⃣ @FisicaUB master students about the use of micrometeorology 🌀 to measure ecosystem gas fluxes and a visit to IDAEA's air monitoring cabins

Please RT: looking for a post-doc in VOC and eddy-covariance in our exciting #ECOSENSE project.

🌞Open positions alert!🌞 We are soon announcing several positions at @VOLT_center in Copenhagen. Lab manager, data analyst, postdoc, PhD student... Stay tuned!

Big #thanks to all the staff at the Abisko Scientific Research Station @polarforskning and the students and other colleagues based in the area for their help during all these years!! Funding by @AgEInves and @DFF_raad

4️⃣ Use a helicopter to lift the box off the forest and move it to a trailer for further ground transportation. Looking forward to the results of these 3 years of field data collection, including a caterpillar outbreak 🐛 this year. [Video by Thomas Holst]

🧵How to wrap up 3 years of #birch #volatile #eddyCovariance measurements in 4 easy steps 👇🏼 @IDAEA_CSIC @Riikka_Rinnan @DrAmySmart @VOLT_center @science_ku 1️⃣ Manually transport the @ionicon #PTRMS box through the forest to the #Abisko #Stordalen eddy covariance tower

Today I will share results of the trace gas flux campaigns in the subarctic of the last few years 🇸🇪 🇧🇻 🇩🇰 #BVOCs #EddyCovariance #tundra #birch 🌡️ #temperature 🐛 #herbivory Come to session ST.05 at 11:45h to find out more! #AEET2023 And at 11:40h @AnaYanezSerrano #bryophytes

8️⃣ "Modeling isoprene emission response to drought and heatwaves within MEGAN using evapotranspiration data and by coupling with the Community Land Model", led by Hui Wang doi.org/10.1029/2022MS…

7️⃣ "Satellite-derived Constraints on the Effect of Drought Stress on Biogenic Isoprene Emissions in the Southeast US", led by Prof. Yuxuan Wang doi.org/10.5194/acp-22…

Many things happened in 2022 that I did not share here yet. 🥳 First of all, at the end of the year I got a permanent position @IDAEA_CSIC 👇🏼
