Surreal time.
I have a large archive here going back many years, been active via networks for longer than most. Some is online.
Trawling looking for useful content to do with a large CET article I am writing I noticed a postscript file (not PDF), open, is the above. (which is bitmap of the ps)
My immediate thought was Climategate followed by clang, not in that disk directory. Timestamp is 2000, plot ceases before 2000.
Usenet archived on Google groups is the IDL version announcement dated 1997, contemporary to my stamp of 2000 assuming it was on a CRU server or similar.

Trawling the net I find someone asked about the parentage of a thumbnail and presentation image… well here it is. It seems f055 was Tim Osborn’s ID so presumably he must have plotted it, finding it’s way to a public access server. This makes sense given a second file would be of interest to me, timed a few minutes differently, NAO.dat (data to end 1997), a specialism of Jones and Osborn.
Why I saved a copy of a plot of no interest? Probably thought it was a document.
A side effect of this is showing there was at least one, maybe many plots available to the public. Perhaps others are lying around. Presumably just of historic interest given subsequent events.

Ah excellent, I hoped someone would be able to place a context.
I’ll send my bill 🙂

SR, quoting a message dated 18/11/1997?
