Particula Paper: Announcement and Call for users

[Gorkowski]

@mahf708 @wkchuang

Here is the paper draft, https://github.com/Gorkowski/Particula_2025_AST_Letter or through overleaf https://www.overleaf.com/read/fjyvxyhhtrtd#386516 view only.

Not sure how we want to handle this as open/closed writing process (and how that works with journal copywrite). But give it a read and let's discuss soon.

I would like to get a short letter out, so people know and can use it before AAAR.

I have the main narrative drafted, if you have time to read it.

Still have to add citations and supplemental information.

I say let's meet and discuss
