Think of how many beer gardens we could build with CMAQ money if State/Lake cost slightly less than $444 million

EPA's ORD destruction is a prime example. And core knowledge from teams like CMAQ dev are moving decades of expertise to air quality science overseas.

Flexing the easy-to-flex federal highway pots like CMAQ & STP is an apolitical, technical process

Believe it or not, it's true of SEPTA's 2026 budget as well!

SEPTA gets $40M of CMAQ flex highway cash this year even with all the cuts. And nobody is mad or thinks it's political

The CMAQ-funded road widening projects will continue until the air quality improves.

Not enough discussion of the Dec. 4, 2025 SCAG Regional Council approval of the Federal Fiscal Year 2026-27 and 2027-28 STBG/CMAQ funding recommendations for $1.25 billion across 132 projects within the SCAG region. Happened the same time as the Metro Board meeting.

It's true (close to it). $167MM in CMAQ, $65MM local, $277MM in Surface Transportation Block Grants (there's your increase), and the rest is change. True local funding at 86%

I was four months into my transportation career and was fortunate to hear this talk at the Bicycle Colorado event. It changed how I saw our agency’s project scoring process and eventually we made some changes after conversations about how certain CMAQ projects actually induced more driving.

This is a very cool visualization but keep in mind AirTox is a screening tool, meaning that it provides a very rough average and upper bound for modeled exposure
(and is even tougher than input models CMAQ and AERMOD)

eg these tools are best used for where to take actual exposure measurements

NEW: Formaldehyde contributes more to outdoor cancer risk than any other toxic air pollutant in the US. It comes from cars, trucks, planes and a combination of emissions cooked in the atmosphere.

For the first time, EPA modeled this risk down to the census block — and we mapped it.

📢 Une avancée historique pour un milieu artistique plus équitable ! 🎉

C’est officiel ! Le RAAV, aux côtés du CMAQ et de quatre grands musées québécois, a signé une première entente collective historique, en présence de Monsieur Mathieu Lacombe, ministre de la Culture et des Communications.

A lot of car trips would be replaced if drivers across our region had easy access to high-quality shared electric bikes at reasonable prices. Federal money is available for it. Whatcha thinking, @mplscargobikelibrary.com? Ready for a massive new funding source? share.google/0cb3HBr5U9cW...

The public hearing as part of the thoroughfare plan amendment for the two-way conversion of McKinney & Cole/Carlisle was TEN years ago. I pitched the idea to Uptown in 2014 and we secured funding from the city bond and federal CMAQ funds in 2017.

Maybe there's an offline barrier to finding CMAQ money, maybe the already-programmed CMAQ uses are too important, or something else?

But the fact is that CMAQ highway funds are flexing to SEPTA this year as previously and apolitically scheduled

This is wonky centrist stuff, not radical

Ellie's first first author paper in our group @ucirvine.bsky.social! We evaluate how well an atmospheric model can predict water-soluble organic gases. It's a novel model evaluation and provides insight for future model development.
Gas-Phase Water-Soluble Organic Carbon: CMAQ Model Evaluation in Baltimore County
Prediction of gas-phase water-soluble organic carbon (WSOCg), a precursor for secondary organic aerosol formed through processing in atmospheric waters (aqSOA), has not yet been evaluated in models. We pair the WSOCg predictions from the U.S. EPA’s Community Multiscale Air Quality (CMAQ) model with continuous mist chamber measurements during February–March 2015 and August 2016 in Baltimore County, MD. We simulate mist chamber collection of WSOCg from CMAQ’s atmosphere with application of compound-specific collection efficiencies as a function of Henry’s law. CMAQ predictions of WSOCg mass concentrations are highest in August, while measurements are highest during February–March. CMAQ does not replicate the average diurnal pattern of the measured WSOCg in any month. The CMAQ prediction of directly emitted VOCs that oxidize to form WSOCg is more reasonable, and the model skill for nitrogen dioxide (NO2) and ozone (O3) is relatively excellent in comparison (R2 = 0.5 and R2 = 0.6, respectively; p ≈ 0). These findings suggest that representation of organic gases and their chemistry in this CMAQ simulation is sufficient to accurately predict the criteria pollutants NO2 and O3, but not necessarily the chemical transformations that produce WSOCg, an important precursor for aqSOA.

Should rethink how we do that CMAQ cost efficiency analysis in light of the Paris case example!
It's official. The Revolution happened, and the bicycles won.
