Though not sure if this just means brick and mortar cults…. Like momma used to make (no shortage of metaverse cults)

Tragic

Come on Joan Didion

I like the tracked changes holdover error getting us started on page 2

vividly remember playing apples to apples in elementary school and the favorite card was always the supermodels card (caption “long legs = big bucks”)

not sure if/what it says about that era

There’s other interesting science in here too, I think (eg how changes in nighttime o3 buffer NOx reductions vis-a-vis ammonium nitrate formation). Hopefully a little something for everyone 🙂

Also surprising is how much effort has been made to match purple air to the FRM/FEM when it performed the best in high ammonium nitrate periods. Our mantra in the field is generally that purple air is over-reporting, but it makes me question many of the corrections we’ve made to that instrument

Susanne Hering (👸) and Glen Cass first pointed out (in 1999) that the FRM is biased for semi volatile species like ammonium nitrate. It is surprising we haven’t adopted even nylon filters so that we can accurately report the PM. It is clear that a great control strategy follows speciated data

This is a super optimistic finding. Yes, ammonium nitrate is underreported. However, that it is ammonium nitrate and shows a dependence on NOx bequeaths a plan. electrification of the vehicle fleet, while good for climate, can still be impactful in 2025 for air quality

I think the most important finding here is that since ammonium nitrate is still pervasive in PM2.5, reducing NOx (eg mobile sources, diesel, off road) is still critical. If the PM was only organic, the control strategy is less clear (especially since we are still fighting over SOA sources)

Thank you🙂🙂🙂🙂🙂 had to fight to keep that phrase in lol
