We worked with @dbm.bsky.social and @mvermeuel.bsky.social using their PTR and our leaf chambers to see RH effects on monoterpenes, MBO, organic acids, and MVK+MACR. While not previously explored in the literature, we think RH effects may explain the variability in previous VOC emission studies

Really excited to share this paper from Mj Riches @chemj.bsky.social showing a humidity dependence on VOC emissions from ponderosa pines. At higher RH, emissions increase substantially - and we explore a few possible mechanisms in the paper.

Among all the eye-popping numbers in the December summary linked below, it's also the first public appearance of this annual weather/climate visualization which I am quite fond of.

Larger version at climate.colostate.edu/co_cag/index... in case resolution here isn't so good. #cowx
Time series graph of temperature and precipitation for Colorado with respect to average, and beneath each graph is a map showing the temperature or precipitation anomalies for each month. This is for calendar year 2025, in which all months but January were warmer than average, and it was drier than average overall.

I usually love seeing my friends quoted in the NYTimes, but the reasons for @marinavance.bsky.social being the focus of this story are so sad. The damage to US science is terrible.

well… your skin lipids undergo ozonolysis pretty much continuously with ambient ozone, creating an array of ketones and aldehydes that you then breathe.

(Us indoor chemists can ruin anything. You’re welcome.)

Not quite the same, but as a grad student, I once ordered a cylinder of nitrogen oxide - or as I wrote it on the purchase order, “NO cylinder“. Cue much confusion about how I would get my calibration standard without a cylinder….

Thanks to Erica Hartmann for leading a newly published paper, "Ten questions concerning indoor dust."

What is it?
Where does it come from?
How does it mediate environmental exposures?
How does it affect chemicals indoors?

A Sharon Begley byline, almost 5 years after her death.

Upon hearing the news James Watson had died, a STAT reporter said in our Slack, "I wish I could read what Sharon would have written."

Incredible news: Sharon in fact did pre-write a Watson obit. And it is masterful and excoriating.

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?
jacquelyngill.bsky.social Jacquelyn Gill @jacquelyngill.bsky.social · Oct 6
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.
