📣 Next #CATCHseminar will be given by @pzieger.bsky.social & Michael Tjernström (Stockholm Uni) on "Atmospheric rivers and the onset of sea ice melt - The science behind ARTofMELT and first highlights". Date: Tues 16 Dec 2025, 14:00 UTC. Zoom link: www.catchscience.org @stockholm-uni.bsky.social

Cool, our ARTofMELT documentary about our expedition in 2023 won the "Best Science Film" Award at the Explorers Festival in Iceland! 🎉🥳👇🏼

Paper Highlight: Heutte, B., Angot, H., Chen, G.I., et al. (2025). Sources and composition of organic aerosols in the central Arctic during spring and summer. Environ. Sci. Technol., 59 (41), 21924-21940. doi.org/10.1021/acs....

Proud to have contributed to this new book about #bioaerosols 🦠 "Biological Highways in the Sky". In chapter 7, we present a summary on the "Release of primary biological aerosol particles from surface waters". Check it out (it's open access!) 👉🏼 www.quae-open.com/product/346/...

New research demonstrates that waves breaking near shorelines release large amounts of sea spray aerosols—boosting both cloud-seeding particle numbers and airborne particulate mass. Learn more in this week’s issue of #ScienceAdvances: https://scim.ag/4oVFiAX

Don't forget next week's #CATCHscience seminar!

NASA’s iconic Goddard Institute for Space Studies—home to Jim Hansen and hundreds more scientists, creator of the GISS model and keeper of the global temperature record—has been evicted from its longstanding NYC office above the “Seinfeld” restaurant. Why? The government told them to move out.

#MeetOurScientists: With the help of a cloud sampler, Aiden Jönsson is able to investigate the particles inside the clouds. Important to better understand aerosols and their interactions with clouds - and how future climate and weather will impact our lives.

New @catchscience.bsky.social paper out in @faradaydiscussions.rsc.org highlighting some of the key open questions in cold-region atmospheric science. Check it out! 👇🐻‍❄️ @bolincentre.bsky.social

Mark your agendas for the next #CATCHseminar by Christian Pilz on vertical properties of aerosols in the Arctic: Wednesday 18th June 2025 (13:00 UTC). More info and zoom link: www.catchscience.org/seminar-series @tropos-de.bsky.social

📣Are you an ECR interested and working on topics around Atmospheric Chemistry? Then join the 2nd IGAC-iCACGP ECR 2025 online conference, which will be organized around 3 different time zones. Abstract until 10th of Aug. More details here: www.ecr-igac-icacgp.org/2025/03/05/i...

75th anniversary and re-launch of the legendary Tellus Journal with amazing science talks and panel discussion at the Royal Swedish Academy of Sciences. @bolincentre.bsky.social

Check out the upcoming CATCH seminar next week Thursday by Christina McCluskey! 👇

Hej Langley, I and a lot of @catchscience.bsky.social will also be at EGU! We will also screen our #ARTofMELT documentary at the EGU GeoCinema. See you there!

New: A NOAA lab in Hawaii that is connected to the longest-running observation of global greenhouse gas concentrations is slated for closure in August, according to a list of lease terminations Democratic members of Congress shared with @washingtonpost.com.

If you have the chance to join a @faradaydiscussions.rsc.org conference, do it! It's an excellent event, where submitted papers are discussed lively and in detail by renowned scientists. I loved it and learned a lot!

By definition, numerical weather models require international data. The atmosphere knows no geopolitical boundaries: any model that begins and ends at its country’s border is unable to generate reliable predictions until after a weather system crosses its boundaries. Which defeats the purpose!

Check out this month's CATCH seminar! 👇

👉Join the information event on Feb 14th, 10-12 (CET) about our *new international master program in climate environment and energy* developed within CIVIS 👉 www.su.se/department-o...

19 years after I attended the European Course on Atmospheres (ERCA), from which I have many good memories, I'm back in Grenoble🇫🇷 now as a teacher 👴 at the new ERCA course (now only 2 instead of 5 weeks). Very excited to be here!

Had a fantastic time at the Nordic Aerosol Symposium (NOSA2025) @au.dk and could also explore beautiful Aarhus and its amazing art. Hope to be back 2025 in Lund, Sweden!

Don't forget to submit your abstract to our session @eurogeosciences.bsky.social "on aerosols, clouds, biogeochemistry over sea ice"! The deadline is Wednesday January 15, 13:00 CET! 👇 #interdisciplinaryscience

Excellent. More than 60 of the largest German and Austrian Universities are leaving X/Twitter due to the lack "cosmopolitanism, scientific integrity, transparency and democratic discourse" on this platform. Press release (in german): idw-online.de/de/news845520 #WissXit

I didn’t include YouTube in this comparison because it isn’t a text-based social media platform… but I happened to notice today that it has limited access to my video about wildfire myths and facts.

🎬 The #ARTofMELT documentary about our expedition to study the onset of sea ice melt is out now! Many nice insights and beautiful images from last year's voyage on the icebreaker Oden. Check out the film by S. Papadopoulou & G. Zetterberg, narrated by Kevin Noone 👉 api.screen9.com/preview/7E1Z...

Bioaerosols make it all the way up to the frozen North Pole, where they can impact clouds! 🦠🐻‍❄️☁️ Check out our new publication led by Julia Kojoj within a fantastic collaboration our H2020 project CRiceS 👉 b.tellusjournals.se/articles/10.... @Stockholm_Uni @AcesSthlmUni

Come to EGU in Vienna next spring! 🌼👇

One of the coolest benefits of working @Stockholm_Uni are the amazing and truly inspiring @NobelPrize lectures at Aula Magna. However, every time I get the feeling that I should have studied something different. Protein design is really fascinating. Wow.

In our new publication led by Julika Zinke, we used optical, fluorescence microscopy and mRNA techniques to study the emissions, enrichment and fluxes of bioaerosols🦠🌊 emitted from Baltic seawater. Check it out 👉 acp.copernicus.org/articles/24/...

Mark your calendars for the next upcoming CATCH seminar on sulfur chemistry in ice cores! Sounds cool! 👇

📢 Registration for the #eScience course is now open! Join us at beautiful @KristinebergC 🇸🇪 🇪🇺 from 5 to 15 May 2025 (+ 2 hybrid meetings). Next year's course will be part of @CleanCloud_HE with exciting new topics around aerosols, clouds and climate! 👉 www.su.se/department-o...

Great workshop last week in the French Alps! Getting ready for the next International Polar Year!

For one year, we measured bioaerosols *in situ* within clouds in the Arctic & studied their sources & potential link to mixed-phase clouds. And yes, we could directly identify them using microscopy! Check out our new paper 👉 acp.copernicus.org/articles/24/... #arctic #bioaerosols #clouds #aerosols

Update from Maïdo Observatory at La Reunion: short but strong rain events cause some impressive water streams running down the volcanic rocks towards our lab. This happens really fast. Luckily our mobile lab with instruments is placed on piles 🌦️🇷🇪🌋 @bolincentre.bsky.social
