Super proud of all my students this summer! Justin and Willow are two great undergrads who presented their summer research during the SURE symposium last week.

We have a new visitor to our garden! It is amazing how gently it can glide over the flowers.

I hope the bees are doing ok with all the smoke up here. This is from the weekend, I see far fewer outside right now.
#AGU26 A098 - Organic Gases, Aerosols, and Surface Chemistry: Sources, Transformations, and Human Exposure Across Outdoor and Indoor Environments Submit an abstract by August 5th! agu.confex.com/agu/agu26/pr...
Organic Gases, Aerosols, and Surface Chemistry: Sources, Transformations, and Human Exposure Across Outdoor and Indoor Environments
Air chemistry research has advanced along separate tracks for outdoor and indoor environments, yet the processes governing human exposure span both. Organic gases and aerosols cross the indoor-outdoor...

I'm very happy to share a new special issue in ES&T Air. "Indoor Air Chemistry in the Context of a Changing Climate" is now available: tinyurl.com/58yz7a5u This special issue was led by myself, Nicola Carslaw, and Yingjun Liu and we'd like to thank all the authors and reviewers who contributed!
Bump! Priority deadline July 15 🧪

It has been criminally underreported but Kelsey Pfendler has just rowed solo across the Pacific Ocean from the US coast to Hawaii in record time. A 2,400-mile unsupported journey in 43 days, 17 hours, and 55 minutes. Notably beating the Men’s record by 9 whole days.
I've never heard these calls before, this is so great!
Timeline cleanse: American pikas calling to each other in the Canadian Rockies. Sound on to hear the loud “MEEP!” made by these potato sized alpine mammals. They’re way off under those cliffs but the calls travel. *this is likely a niche post, but it’s one of my favorite sounds in the world.
That’s what happens when you get rid of the department of defense
It is ridiculous that journals want me to pay for a paper published in 1948.
ACS ES&T Air’s latest collection explores how the field of atmospheric chemistry has advanced thanks to the collaboration of industry, academic and federal scientists This list of papers offers insights into the value of cooperation that has shaped 30 years of atmospheric research buff.ly/n0GsJd8
my hot take is that this is the actual america 250. just a ton of different people coming together, showing people what makes America weird and fun. people being welcoming. and yeah there’s some bullshit too, which is also very true to America! but the good and community far outweighs it rn.
What a great article not only on faculty workloads, but how little our salaries actually factor in to most university budgets. A few highlights. First, our salaries are falling:
Does anyone else find that AI written text flows right through their mind? I know students are using it to try to learn in class, but I retain very little when I read it.
Things I never thought I would type: look at how they greeted the Algerian team arriving back at the DoubleTree in Lawrence, Kansas
We got a big bump in traffic yesterday when people learned about us on NPR. Thank you to @npr.org for covering our launch and bringing our story to people's attention! And thank you to all our new followers. We can do this together! 🌍️🧪💪 #ClimateAction #ClimateForUs #ProtectScience
Gutted to hear of the passing of V. “Ram” Ramaswamy, who had led NOAA's influential climate lab, GFDL, since 2008. He had a truly American success story and lasting legacy. May his memory be a blessing to his friends and family.

There were many beautiful flowers in the SF botanical garden, but this was my favorite. Such a beautiful dark color and it smells like chocolate!
I'm happy to share an editorial in ES&T Air highlighting the importance of collaboration in atmospheric chemistry between academic, federal, and industry scientists. As we face growing challenges in air quality, we must continue to support collaborative work at all scales. tinyurl.com/3szhhdtm

In California and I saw my first passion flower. What a crazy cool bloom!
I wish there was a way to send updates to previous proposal reviewers who rejected an idea when we, or someone else, prove an idea was possible.
