Look good to me.

@gspetro-NOAA - Thank you for making the previously suggested changes! I've found two spelling issues, and I had a question regarding the VX_NDIGITS_ENSMEM_NAMES variable (should the example show the same values, such as "mem002" to "mem02"). Once these have been addressed, I'll give my approval.

@mkavulich - During the SRW App CM meeting on September 21, you offered to review the documentation updates in this PR. I'm checking to see if you are still planning on reviewing these changes. If you are, then I will hold off on approving and merging this PR until you have had the opportunity to review these changes. Otherwise, I will go ahead, give my approval, and merge this PR. Please let me know as soon as possible whether you would like to review these changes or not. Thank you very much!

@MichaelLueken @gspetro-NOAA apologies for letting this slip! I'm reviewing now.

Thanks for this big effort @gspetro-NOAA, this looks like it was a lot of work! Sorry the review took so long, and I admit that I didn't deeply read all the wording changes towards the end, mostly concentrating on the variable names for correctness.

Only a couple of these are corrections, most of these are optional changes so feel free to rebut my suggestions.

Thanks for addressing those comments, and opening the new issue #922
