Spent the day installing our Picarro formaldehyde instrument at the ASCENT site in Denver.
I have heard rumors that the European Union is planning to end the TROPOMI measurements onboard the Sentinel-5P satellite, now that Sentinel-5 is in orbit. If you are as concerned about this as I am, please consider sharing this post and/or signing this letter: www.ipetitions.com/petition/tro...
Petition TROPOMI's Future
Urge the EU to continue the TROPOMI measurements.

This is quite extraordinary- scientists set a kind of trap for AI chat bots by inventing a fake disease. AI told people it was real and… the deliberately bogus preprints started being cited in peer reviewed literature 🫣 🧪 #MedSky www.nature.com/articles/d41...
Scientists invented a fake disease. AI told people it was real
Bixonimania doesn’t exist except in a clutch of obviously bogus academic papers. So why did AI chatbots warn people about this fictional illness?

A new paper from Madison Rutherford studies SOA formation from the use of germicidal UV in an office. She also found that many VOCs increased in the office when the GUV lamps were on, apparently from surface reactions of ozone or direct irradiation by the lamps. doi.org/10.1021/acsestair.5c00475
Measurements and Modeling of GUV222-Driven Increases in SOA Concentrations in an Unoccupied Office
The COVID-19 pandemic led to heightened interest in germicidal ultraviolet (GUV) lamps, which can deactivate bacteria and viruses in infectious aerosols. Recently, lamps using 222 nm (GUV222) light to...

I am very proud of this paper from Will Dresser in our group: he participated in a laboratory study led by Shantanu Jathar to investigate the emissions from the burning of building materials. What we found is that emissions of some toxics like benzene are far higher from the burning of plastics.
Being nice to CU is a big thing in Korea. Many of their convenience stores advertise it. @colorado.edu

Two new graduate students are joining our group. Heejoo Kang comes from the Gwangju Institute of Science and Technology and is interested in formaldehyde. Audrey Lyp holds a BS from the University of Wisconsin-Madison and wants to work on wildfire impacts on the atmosphere. Welcome both!
Great to see so much support from our community for NCAR.
As 2025 is drawing to a close, it is time to commemorate the group's highlights and one lowlight. Our group had a great year despite all the upheaval in the science world. Let’s get started.
Unfortunately, I will not be at the AGU Fall Meeting this year. There is too much work left as Department Chair, plus I am prioritizing the travel of my students. Our group will be represented by Lindsey Anderson, Drew Blauth and Nathan Sweet.
Oh no! Sanitas Brewing is closing. A mainstay for meeting fellow scientists. Many ideas must have been born here. The place also kept us sane during the pandemic when we met weekly to eat and drink on the outside patio. sanitasbrewing.com/boulder-sani...

I am able to sponsor postdoctoral fellows through this program! www.chemistry.ucla.edu/bhaumik-priz...
Bhaumik Prize Postdoctoral Fellows Program – UCLA
The Departments of Chemistry and Biochemistry and Physics and Astronomy at the University of California, Los Angeles (UCLA) invites nominations for the Bhaumik Prize Postdoctoral Fellows Program. This newly instated program seeks to bring the brightest young scientists to UCLA to expand their scientific training, make new discoveries, and network with interdisciplinary scientists of all stages. The Bhaumik Prize Postdoctoral Fellows Program is made possible by the philanthropy of physicist and entrepreneur Dr. Mani L. Bhaumik. The program supports three fellows annually for a three-year postdoctoral position.
