What surprises me is that all this material, including the hand-tabulated
observations and the paragraphs of text, was still being produced during war

Yes. I see that, not surprisingly, there was a gap from about April 1945
for just over a year.

It's marvellous that it has survived but a bit sad that it has been made
available only through the auspices of NOAA in the USA.

Indeed. It's also sad that one can't see archived Met Office data being
made available any time soon.

It's a pity that the files have been made available only in PDF and TIFF
formats; I suspect that JPGs would have been a fraction of the size with
no noticeable loss in quality.
