Congratulations to John Mak and all of GOTHAAM. The NSF-NCAR video summary really captures the magic of atmospheric chemistry

🥲

I want to see Mamdani win in NYC tomorrow for a lot of reasons, but one of them is absolutely to watch Bill Ackman crash out

Interesting to wake up to this the weekend after Halloween. It's a shiny version, but I wonder if someone down the street had this as a decoration 🤡

A movie you've seen more than 7 times with a gif

This is very interesting. If true, it means we could see what prompts someone used to create things with LLMS that they post or publish.

All the generative AI junk that pops up everywhere makes me want to go back to typewriters and fax machines and hand written letters. There should be a global AI "off" switch for user systems.

CIRES is looking for an Associate Director for Science. This is an important role working directly with the CIRES Director and leadership on CIRES' science mission. Please share with colleagues who may be interested. jobs.colorado.edu/jobs/JobDeta...

Working on a paper with a graduate student is such a cool experience! It is so different compared to what I've done before.

This summer's GOTHAAM campaign to unravel the determining chemistry that affects air quality in the complex NYC metropolitan area - Led by John Mak and supported (A LOT) by NSF-NCAR Independent federal #science safeguards human health & the environment @ncar-acom.bsky.social

Some places in Jamaica will receive more rainfall from hurricane Melissa than London or Paris receives in a year! It’s noteworthy that scientists and technicians from NOAA’s National Hurricane Center who are tracking the storm are not being paid because of the Republican government shutdown.

One of the many things @ninalakhani.bsky.social does so well is show the very real, very now cost of climate change at the most human level. This story is devastatingly good: www.theguardian.com/environment/...

Noooooooo!

This is both a little sad, but also cool. We gave ourselves a ring!

I'm so happy to have served AAAR as secretary for the last 3 years. It was a great honor to work with the other members of the board and especially the presidents: Leah Williams, @vfmcneill.bsky.social , and Amy Sullivan! They are a wonderful group of leaders and mentors. #AAAR

So proud of my group for our first AAAR meeting! We had 3 poster presentations and one platform presentation. AAAR is a great meeting and it was so great to bring students to this fantastic community! #AAAR2025

All-time great plenary this morning on aerosol monitoring networks in the US and globally by Ann Dillner #AAAR2025

The David Sinclair award went to absolute powerhouse of aerosol science Jonathan Reid And Jason Surratt @surrattairchemlab.bsky.social was recognized by many generations of of his group members and AAAR for his excellence in teaching, mentoring and training 💖💖 #AAAR2025

Absolutely star studded awards ceremony this morning - Welcome new AAAR Fellows Jesse Kroll @jessekroll.bsky.social and Pat Keady! AAAR Fellows make up 0.2% of the AAAR membership. They are recognized for their significant contributions to aerosol research and service to AAAR #AAAR2025

I love when you go coat shopping and you try one on and it practically becomes part of your body. It's rare when things fit well.

Like a canary in coal mine…

The recent Chevron refinery fire highlights why we really need some of the agencies that have been, or that are being, shut down. The Chemical Safety and Hazard Investigation Board (CSB) is one of many that help keep ourselves and our communities safe. shorturl.at/bt2CK

I need a little timeline cleanse. I love the colors of a monarch against a flower. It's so cool how two colors I wouldn't normally pair work so well together in nature.

Semi-random question. Every now and then I accidentally archive an email in Gmail. I know how to undo this, but I don't understand that feature. Does anyone use that archiving on purpose? I'm trying to figure out how it could be helpful.

I am able to sponsor postdoctoral fellows through this program! www.chemistry.ucla.edu/bhaumik-priz...

We have a new PhD project to study ozone formation from fires. If interested in atmospheric chemistry, fires, living in Zurich, and studying at ETH, consider applying here: jobs.ethz.ch/job/view/JOP...

If you know folks that were impacted by the eligibility changes to the #GRFP last week, please consider signing/sharing this urgent petition to restore eligibility! 🙏 bsky.app/profile/omfi...

So they finally posted the GRFP info. The big news I see is that it's now closed to second years. This really sucks for students rotating to find a lab in their first year. IMO a year's warning would have been more appropriate. www.nsf.gov/funding/oppo...

Congratulations to Cora Young, @svocora.bsky.social, for the AGU Ascent award!! tinyurl.com/5v8fj8b7

As a geologist with some experience working with biologists, one of my favorite things is when they refer to certain snails as "terrestrial snails." I know this is to distinguish them from aquatic snails but it also implies the existence of extraterrestrial snails, which I am 100% in favor of.

Our paper examining the chemical conditions of past chamber studies is out! This work explores assumptions made when creating SOA parametrizations based on laboratory data, and can hopefully point to ways of improving model representation of SOA. pubs.acs.org/doi/full/10....

Chemicals "stick" to surfaces in houses, to a greater degree than some might expect. This is why you smell the popcorn you burnt long after you might expect it to vent from the house. (Full disclosure I am a co-author on this paper)... www.pnas.org/doi/10.1073/...

Living a moral life in an age of bullies requires collective action; it cannot be done alone. Each of us must organize and participate in a vast network of moral resistance. From this solidarity we will grow stronger. This is what our current moment requires.

My first NASA position, as a contractor in the Kepler Science Office, was on a H-1b visa. NASA ended up giving me a medal and now I’m the Chief Scientist of NASA Exoplanet Science Institute and an American citizen to boot. Seems like a net win for the US, no? But now this:

Rick introduced me to the world of research and environmental work. He believed in me and encouraged me at many times when it felt that no one else did, and I still look to him for wisdom and advice. And of course he is a hugely creative and inspiring pioneer in aerosols research. Cheers to Rick!

In the US, PM₂.₅ from wildfire smoke already kills about the same number of people as guns and cars (~40k each), but this will increase significantly with climate change. 😐

Kīlauea is showing some intermittent small eruptions that look very pretty in the dark! Live feed from USGS: m.youtube.com/watch?v=tk0t...

A great new position in my department. Please share with folks who may be interested!

Sometimes I look back through my photos and think about all the incredible plants/animals etc. we have on this planet. Why are we not doing everything we can do to protect them and our ecosystems?

Today we joined Natalie Mahowald, Lead Author of the IPCC 1.5SRE, to have a wide-ranging discussion on the topic of geoengineering, from the science to the governance challenges and ethical implications. Thanks to @cornelluniversity.bsky.social for organizing! www.youtube.com/watch?v=o15F...

At the arboretum today enjoying the colors and views at the end of the summer.

"Manufacturers, regulators and airlines have said these types of incidents are too infrequent, levels of contamination too low and scientific research on lasting health risks too inconclusive to warrant a comprehensive fix." There should not be such a high bar to enact change.
