It would be nice to see how California compares in terms of emissions per resident. It's unclear why it would be much different from some neighboring states with smaller populations.
There was essentially no detected sulfyryl fluoride outside of California. They don't really guess why that is, but the authors do seem surprised by it
A caveat was that they don't have good detection networks in Florida, but determined that it must be significantly less than California due to the ability to detect emissions traveling away in South Carolina.
