Dr. Wall told me she created SOGES at CSU so that faculty had a refuge where scholarly conversation and collaboration could flourish, unhindered by academic barriers. She succeeded in that vision, in a space where many before her did not. Thank you, Diana.

Boom. This new annual PM2.5 limit (9 ug/m3) chosen by EPA represents great progress towards cleaner, healthier air for everyone. In Colorado, you can expect visibility to improve along the Front Range as a result. stocks.apple.com/AKFmRuyA7Tr2fW…

Teardown-> model of the PM sensor shows
1. It’s a PM counter, not a nephelometer.
2. It can count 0.3-0.5 um particles and that’s about it.
3. It CANNOT report PM size distributions, PM coarse, PM10

Worried about all that smoke outside? Wearing a well-fitting N95 outdoors will make a big difference. @projectn95

Buildings breathe. If it's smoky outside, you should be taking precautions to protect your health indoors as well as out. I walked through every possible home configuration I could think of with John Volckens (window a/c? central a/c?) to find out what to do. heatmap.news/wildfire-smoke…

If you’re worried about inhalation, go grab that mask you set aside on May 11. It will help…a lot.

Good morning ! Feeling run down? Itchy eyes? Sore throat? Headache? It’s probably not your allergies. We have a massive .5 intrusion from Canada. Stay indoors and run those air cleaners! Real-time info here: fire.airnow.gov

Imagine how your lungs would feel if your kitchen stove was an open fire burning indoors... Campfires are for camping, not everyday cooking. Thanks to Nate Seltenrich Environmental Health Perspectives for spreading the word on this global health and climate issue. ehp.niehs.nih.gov/doi/10.1289/EH…

Seeing 'The Mask Mandates Did Nothing' trending is an illustration of how opinion editors at mainstream outlets spread disinformation about science and cause mass harm.
