This work started already pre-covid, which makes me even happier to see it finally in print. Thanks to @ayanezserrano.bsky.social for tremendous leadership in pushing it all the way through!

Unaccounted impacts of diterpene emissions on atmospheric aerosol loadings Communications Earth & Environment - Diterpenes are an underestimated source of secondary organic aerosol, accounting for up to 13% of the secondary organic aerosol burden from isoprene,...

Happy to announce that our paper on "Unaccounted impacts of diterpene emissions on atmospheric aerosol loadings" has been published after years of efforts. Thank you!@mikaelehn.bsky.social @jpreixach.bsky.social @olgagarmash.bsky.social @apraplan.bsky.social @heidihellen.bsky.social

How a corpse plant makes its terrible smell − it has a strategy, and its female flowers do most of the work When a corpse flower bloomed on campus, atmospheric scientists got to work. What they discovered provides new evidence about the unique pollination strategies of a very unusual flower.

A rare bloom of Cosmo, CSU’s corpse plant, gave my group (Rose Rossell and @chemj.bsky.social) the chance to study corpse flower emissions in a fun collaboration with Tofwerk. Turns out to be an interesting, if stinky, story of pollination chemistry…

Sad I didn't manage to go to there myself this time, but thanks to Mace Head team for hosting these campaigns!

Climeworks’ capture fails to cover its own emissions The carbon capture company Climeworks only captures a fraction of the CO2 it promises its machines can capture. The company is failing to carbon offset the emissions resulting from its operations – wh...

There is some "amazing stuff" in here on Climeworks and carbon capture / carbon offsets model more generally.
brief🧵 after the caveat that I have no idea if what is reported is true (but it mostly doesn't matter whether/if the numbers are off by >10x)

EGU coming up next week! See below for details on our session on atmospheric organics. Hope to see many of you there!

High sensitivity of cloud formation to aerosol changes - Nature Geoscience In situ observations indicate a greater susceptibility of cloud droplet number to cloud condensation nuclei than is estimated from satellite observations, which suggests that aerosols exert a stronger...

Oma kokemus: ChatGPT sanoi osaavansa kääntää MatLab-scriptin Igor-koodiksi. Generoi testipätkästä ihan kivannäköisen koodin. Tarkemmin tarkasteltuna siellä oli kuitenkin paljon virheitä. Jopa for-loopin syntaxi pielessä. R ja Python varmaan AI:lle helpompia, mutta kannattaa aina tarkistaa tulos.

Hello Bluesky! EGU is pleased to be able to activate our account here, and share all the exciting news about the upcoming General Assembly: #EGU25, our #OpenAccess publications and more! Several of our Divisions will be making the move over from Twitter/X too, so keep an eye out for your favourites!

Just over a week until EGU abstract deadline (Jan 15)! Come join us to learn about atmospheric organics! Featuring invited speakers @riikkarinnan.bsky.social and Matthew Coggon.

Maybe they want to convey that there's still plenty of room for things to get much worse...?

EGU 2025 coming up next spring, check out our session on atmospheric organics!

Characterization of the Vaporization Inlet for Aerosols (VIA) for online measurements of particulate highly oxygenated organic molecules (HOMs) Abstract. Particulate matter has major climate and health impacts, and it is therefore of utmost importance to be able to measure the composition of these particles to gain insights into their sources...

My postdoc Jian Zhao did a great job in figuring out how to improve the performance of the vaporization inlet for aerosols (VIA). One of these days we need to do a direct comparison with the EESI-TOF to compare spectra and sensitivities for online detection of SOA.

On the potential use of highly oxygenated organic molecules (HOMs) as indicators for ozone formation sensitivity Abstract. Ozone (O3), an important and ubiquitous trace gas, protects lives from harmful solar ultraviolet (UV) radiation in the stratosphere but is toxic to living organisms in the troposphere. Addit...

Can we, in real-time, deduce the ozone formation regime by measuring highly oxygenated organics (HOM)? In theory, yes. In a simple lab system, yes. In ambient air, we are still looking into it. In any case, since HOM were discovered, we have thought about these links, so was nice to now test it.

Finally I can identify with your posts! 🙁

I cannot identify with a single thing you said in this post! 🙂

I hadn't checked X for quite a while. Following your post I now did, and finally made the choice to completely deactivate my account there.

Now that AGU has wrapped up, time to start thinking about EGU in April! Abstracts are due Jan 10. Consider submitting to our session on organics:

If you are interested in atmospheric organics and conferences in Vienna, please consider submitting an abstract to our session at EGU24!
