Good to talk to USA Today about changes in air quality trends in the U.S. and the role of wildfires. Nice interactive resource to check for your county.

Crisis: The Time to Act is Now
#Delhi and parts of Northern #India, experience highly #polluted #airquality year-round with spikes during the winter months (10 – 20x > Indian standard & > 100x #WHO guidelines for # PM2.5). (2/3)
We lay out a multi-pronged strategy and action plan that need to be executed urgently by all stakeholders to make the Capital (population of > 30M people) and other cities #smog-free and to make the growth #sustainable. Let us do it collaboratively.
See recent paper on #spatiotemporal trends in #PM25, while also noting that the #chemical composition of PM2.5 has changed quite a bit. Great work led by Bin Cheng who showed this variation by US region – at North Carolina, USA
@UNC_IE's @picai and Bin Cheng share results of their latest study with Newsweek.

The front page of tomorrow's @dailytarheel –
I shed many tears while typing up these heart-wrenching text messages sent and received by UNC students yesterday. Our campus was on lockdown for more than three hours.
Beyond proud of this cover and the team behind it.
If you are using HPC for your air quality assessments, see new guidance from @CMAS_Center on using cloud computing to run #CMAQ. 2023 Annual Conf in Chapel Hill will also have a half-day hands-on tutorial on how to configure and run CMAQ on a cloud instance. Advanced Regn reqd
