Hey Colorado residents, particularly people in Fort Collins, but also those who are somewhat near: my sister and brother in law are running a study on an easy, portable method to help maintain indoor air quality during adverse outside events (like smoke or pollution).

I think this explains what is going on with papers at JGR-Atmos - I have two stuck in reviewer purgatory for >90 days!?! Anyone else?

Jacquelyn Gill @jacquelyngill.bsky.social · 9d

The new Wiley journal review system is an absolute nightmare. Editorial assistants have been replaced by a clunky, AI-enabled website that makes it harder to find and invite reviewers. Associate editor workloads have increased. I'm not convinced the invitations to reviewers are even going through.

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

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.

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.

See below for the tumultuous past three weeks about funding new awards (separate from terminations...).
