I stand with NCAR! Research at NCAR benefits society through accurate forecasts with lower economic losses/property destruction, better air quality, a healthier ecosystem, and educating the next generation. #NCAR #saveNCAR

Congratulations to recent PhD student Dan Moore: greenhouse gas and ammonia emissions from the wastewater sector require mitigation and are critical to global, urban net zero plans. @SloanFoundation @WaterResearch nature.com/articles/s4422… engineering.princeton.edu/news/2025/10/0…

@JACPton @Princeton They subsided, hard to see much right now, but I would recommend to occasionally look for the rest of this evening. If another “substorm” happens, it will return. Hard to know if the whole storm is subsiding (doesn’t look like it yet) or if this is just the usual ebb and flow.

@PrincetonZondlo @Princeton Made me look, couldn’t see it

Atmospheric chemistry in action, even in twilight, with the moon, and in light polluted central NJ: aurora!

@HopkinsLabUCR @MichaelVRod3 @UCRCNAS @ucr_sacnas Congratulations, Michael!

Couldn't be prouder of Dr. Michael Rodriguez!!! A true all around environmental scientist able to collaborate, work in the lab and field, use computing tools, and communicate science to broad audiences. Good luck on the postdoc at UC Merced! @MichaelVRod3 @UCRCNAS @ucr_sacnas

Hey, @UPS That case of scientific instruments to be delivered **overnight** to NASA Armstrong **last** Monday 12/11 that you are “investigating” with no info for days? It is about to enter the Land of Oz. Is your customer service the witch of the East or West?

Super fun group/alumni dinner with such talented people - thanks, everyone! A most rewarding part of my job!

Professor Mark Zondlo @PrincetonZondlo will present “Mysteries and Challenges of Agricultural Emissions to the Atmosphere” TODAY at 12:30 p.m. for our second fall ’23 HMEI Faculty Seminar. #agriculture #emissions #atmosphere environment.princeton.edu/event/mysterie…

One of the best media descriptions of a field project ever - happy to ride along with NOAA AEROMMA on the NASA DC-8. Kudos to @KrisHabermehl for conveying both thorough info and excitement in reporting! #AEROMMA cbsnews.com/chicago/video/…

A long time in the making, OPALS (Open-Path Ammonia Laser Spectrometer) flew on the NASA DC-8 aircraft successfully - thanks to the many who helped get us here!

This week, @NOAA satellites are monitoring even more thick smoke from #wildfires burning in Canada that has been blowing over the eastern and central U.S., triggering air quality alerts in many areas. Learn more in our latest #EarthFromOrbit video: bit.ly/43vzZgx

@mollyaseltzer Thanks for the opportunity to talk about this and for those who participated with the great questions! Thursday will be improving in the mid-Atlantic/NE but it just means somewhere else will be getting the worst (Ohio, w PA). Stay safe out there!

I had the pleasure of interviewing air quality expert @PrincetonZondlo about what's going on with the air & the Canadian wildfires. This thread has top takeaways & watch the full interview on Princeton's Youtube channel.

People asked me how they could ensure the air inside was healthy if they didn't have a central air filter or air purifier. Here is a simple do-it-yourself project that is as effective, Corsi-Rosenthal box: cleanaircrew.org/box-fan-filter…

The peak hourly PM2.5 Air Quality Index (AQI) values today in Trenton, NJ (PM2.5 AQI=172, corresponding to PM2.5=~99 µg/m³) exceed the previous record (daily) values (from July 2002).

What can you do to avoid the very unhealthy air? Avoid outside especially exercise (N95 mask otherwise), recirculate air inside through central HVAC filters, and turn on air purifier within room. And think about what other parts of the world go through on a near daily basis...

Visible satellite (overlaid with air quality stations) shows the heaviest smoke impinging upon Princeton now, expect even more degradation of air quality in the next few hours.

Smoke & haze continue to move in from the north. In this satellite loop, you can see a thicker plume over central NY and northern PA which will be shifting in over the next few hours. Expect a reduction in visibility, poor air quality & the smell of smoke. #NYwx #NJwx #CTwx
