This summer's GOTHAAM campaign to unravel the determining chemistry that affects air quality in the complex NYC metropolitan area - Led by John Mak and supported (A LOT) by NSF-NCAR Independent federal #science safeguards human health & the environment @ncar-acom.bsky.social

Field demo from rapidly changing northern ecosystems. This shows a violent stream of methane bubbles venting through thawing permafrost soils to the sky. Video credit to Tom Douglas and Torre Jorgenson. Curious bog dog is a Friday bonus.

Out this week in npj Climate and Atmospheric Science: VCPs, biogenic VOCs and traditional anthropogenic PM respond to heat and smoke to drive summer PM pollution outside NYC, highlighting vulnerabilities of urban air quality under global change. @chemdelphine.bsky.social @dbm.bsky.social

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.

Come join us in NYC! We are hiring an Assistant Prof. in my Dept at Columbia - info below. Review of applications starts in October.

Atmospheric Physics faculty position at Univ of Toronto - help us make use of satellite and aircraft capabilities that are on their way in Canada! jobs.utoronto.ca/job/Toronto-...

Nice article about the DOE report and how the scientific community is responding www.newsweek.com/why-trumps-m...

On Friday, June 20 we lost contact with our methane-measuring satellite. Despite considerable efforts we were unable to reestablish contact. This morning we learned that the satellite has lost power, and it is anticipated to be unrecoverable. methanesat.org/project-upda...

Cuts have consequences, illustrated. As seen on TV 📺

200+ scientists are in the middle of a marathon livestream to show why weather and climate science is so important and needs all our help to continue. It is here: wclivestream.com/watch

Given the news about Harvard and maybe more coming: my university (Queen's, Canada) has some spots/funding for students accepted to US institutions who need a new spot. If you know of students in that situation they can reach out or check here: www.queensu.ca/grad-postdoc...

⏰ I’m advertising not 1️⃣ but 3️⃣ positions!⏰, one RA and two #PhD s (fully funded 4 year EU/UK fees) as part of my team at @tcddublin.bsky.social looking at how roots work in natural ecosystems and influence greenhouse gas fluxes 🌏 🍃 🌲 💻

I will give one of the talks, and I hope if you’ve ever been funded by a US government grant, you will do the same. Everyone else, please turn in.

The Five Boro Bike Tour is an awesome 40 mile ride through NYC. I highly recommend it. This year I did a slightly modified version so I could stop at 44 miles. But it meant I got to see the NYPD escort the lead pack of 32,000 bicycles out of Central Park in style!

And PLEASE do not use your gas stove or oven if you rely on a window for ventilation of the exhaust (ie. most apartments in NYC).

We are searching for a Group Leader in Experimental Atmospheric Chemistry! You can find details in the link; please share with qualified colleagues! jobs.ethz.ch/job/view/JOP...

Huge wildfire burning in the Hamptons. Many of the trees in this area have died from pine-beetle infestation, & the whole tip of LI is "abnormally dry" after a year of on-and-off drought. And this is one of the richest parts of the country. Yes, #ClimateChange IS going to hurt the affluent too.

Adding to what Dan and others have said: Measuring air quality at diplomatic posts in places like Beijing, Delhi, and Lahore, using EPA standard technology, and openly sharing it with the public, has been a force pushing along progress toward better air quality in all those locations.

The Iditarod route will be over 1100 miles this year due to lack of snow... apnews.com/article/idit...

Hello out there scientists. If you're having meetings or grants or anything else impacted by freeze of NSF meetings, please feel free to reach out to me to share your story. Signal: thealexknapp.79 Email: [email protected]

One way to make fieldwork more personal is to measure from an observatory that you can see from your subway stop 🤣

🧊🔥 New paper @natclimchange.bsky.social: After millennia as a carbon deep-freezer for the planet, a third of the Arctic-boreal zone is now a CO2 source to the atmosphere. The int’l research team was led by @annvirkk.bsky.social ⬇️ Learn more: permafrost.woodwellclimate.org/after-millen...

Collaborative synthesis #science like this is crucial to understanding climate trends and advancing pan-Arctic monitoring efforts. Congratulations @annvirkk.bsky.social @woodwellclimate.bsky.social & all co-authors, incl. @roseatmos.bsky.social @thissideofthearctic.org! 🗺️ by @gfiske.bsky.social

#JPL has so far been safe as well thanks to round the clock work of our first responders. But over 150 JPLers have lost homes that we know of so far. We are raising funds to support them through Caltech! Please consider supporting: caltech.imodules.com/controls/ema... Thank you!

The stratospheric polar vortex will be in strong vortex mode at Christmas, with average zonal winds at 10 hPa reaching over 60 m/s. The last time we had such a strong vortex in December was nine years ago, in 2015 (as per NASA MERRA-2 reanalysis: ozonewatch.gsfc.nasa.gov/meteorology/...).

We've seen massive N2O plumes in NYC over the years and it took me forever to link it to a wastewater treatment plant 3(!) km away. I just couldn't believe something that far away could be the source. But seeing ppm levels of N2O outside the plant made me a believer! Lesson: measure N2O in cities.

Happy Solstice, everyone! ❄️🌍

New from @mvermeuel.bsky.social @dbm.bsky.social @timothybertram.bsky.social @chemdelphine.bsky.social and colleagues (+ me): A vertically-resolved canopy improves chemical transport model predictions of ozone deposition to north temperate forests in @agu.org JGR-Atmos. doi.org/10.1029/2024...

Do you want to know the atmospheric concentrations of methane, CO2 and CO around New York City? The first version of our Data sharing website is live! nyaaq.ldeo.columbia.edu/content/data... The page is still a work in progress. What are we missing? What other info would be useful?

I usually just attend research talks at #AGU24 but this SY session looks really interesting. Oral session this morning at M4 in the Marquis. Poster session this afternoon. agu.confex.com/agu/agu24/me...

📢#WeAreHiring! I am looking for a #postdoc (2yr position) either in ecological modelling or experimental trait-based ecology to join us in Northern Biodiversity and Ecosystem functioning group at @helsinkiuni.bsky.social Thanks for reposting! jobs.helsinki.fi/job/Helsinki...

🧪 Hey , here is a starter pack for those interested in #atmoschem prepared by @coletteheald.bsky.social go.bsky.app/GgmWgSo

So... #AGU24 is next week. Can we bsky-source a list of talks/posters to attend? Classes are full on till the end of this week and then I have grading to do. Nevermind the proposal that is due on the Monday of AGU!? So, who wants to suggest what/where/when I can't miss next week?

13 days left to apply for this PhD position in my group. Please forward to talented Masters students in atmospheric chemistry!

We're hiring at the U. of Arkansas! Asst. Prof. with the aim of a research program focus on circular bioeconomy systems, teaching, service, and mentoring graduate students and research staff. Tenure will accrue in Dept. Biol. & Agric. Engr. Apply: uasys.wd5.myworkdayjobs.com/en-US/UASYS/...

Today, I got to tell one of my favourite jokes in class (teaching spectroscopy). Q: What happens to rainbows when they commit a crime? A: They go to prism. Don't worry, it's a light sentence. #ChemSky 🧪

Yes, if scientists can stop us from emitting 40+ billion tonnes of CO₂ every year. No amount of CO₂ removal, solar radiation modification, or synthetic fuels will help unless we stop burning fossil fuels.

🧪 Now that the higher resolution image arrived (MODIS), it is easier to make out what is dust and non-dust just by eye (or a trained eye, 😀) . Unfortunately, no images from the Sentinel/Landsat. @sheffielddust.bsky.social

The Philippines have now been hit by four typhoons in the span of just 10 days. Can't say I recall ever seeing this before.

Does anyone know why the #airquality in Bosnia-Herzgovina is so bad (even relative to places around)? I know there is a valley but this seems a lot and it has been for the few weeks I have been looking! map.purpleair.com/1/b/i/lt/mAQ...
