This work hinged on combining bulk ACSM and speciated GCxGC measurements plus a vast array of other instruments - and a boatload of data analysis. Congratulations @emfranklin.bsky.social & thanks to @dbm.bsky.social @roseatmos.bsky.social @mvermeuel.bsky.social @reobrien.bsky.social + the FROG team

New paper on what drives organic aerosol in NY - anthropogenic chemicals have emerged as 2x traffic sources, while wildfire smoke is persistent and substantial - and we see evidence that it enhances biogenic SOA.

Spooky season approaches, so I'm going to repost some of my Halloween comics from years past.

A four panel comic called Happy Halloween From The Birds. In panel 1, a pileated woodpecker has pecked its huge gaping rectangular holes in a pumpkin. In panel 2, a yellow-bellied sapsucker has pecked a face using its standard rows of small holes. In panel 3, a satin bowerbird has carved a pumpkin into a bower and placed its favorite blue candies all around it. In panel 4, a loggerhead shrike has impaled mini pumpkins on a fence's metal spikes and is saying "fight me."

I do not want the video. I will never watch the video. I usually won’t even give the video the effort of complaint.

I just want to read the news story. Give me the text. This would be my Ted Talk but that would be text too.

NSF today released instructions for the next round of applicants to its Graduate Research Fellowship Program. A key group—second-year Ph.D. students—is no longer eligible, and students who are still able to apply will face an unusually narrow timeframe. https://scim.ag/3KlQkQk

‘Completely shattered.’ Changes to NSF’s graduate student fellowship spur outcry

The announcement comes months later than usual, leaving many would-be applicants stranded

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…

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.

So it’s been about four years in the making, but #GOTHAAM is finally happening. We’re two weeks in with a phenomenal team - and some impressive datasets! Three Farmers flew today and we had a blast taking transects of urban pollution plumes and then studying stratification over the ocean!

A rule of thumb for tsunamis is that in open ocean, they move at similar speeds to commercial airliners. If you're ever curious how long it would take for a tsunami to get from one place to another, look up the duration of a similar-length flight.

🧪 NEW: NSF staff were told yesterday to stop "all funding actions" until... "further notice."

That includes new increments on continuing grants.

I am so sad to see this. This organization is essential for understanding pollution and its impacts. The people who work there are incredibly dedicated, experienced, and world leaders. This is incredible loss of national investment and capacity.

Yeah, I think there is a certain amount of mixing correlation and causation in that interpretation of this plot… I think one would have to separate out by cause of death (heart attacks or just more car accidents because people are walking around more in the spring and summer in Europe?).

This is such a loss. I've served on the selection committee for this program for the past three years, because it has funded so many incredible people doing such important research over the years. It should be expanding to meet the new challenges of climate change, but instead is totally defunded.

Now we aren’t allowed to have in person panels.

Screenshot from NSIDC that says: "Dear Colleague:
