There's a readable version of the longer list chart here:

Here is a longer list for pre-1960 rainfall observers doing 40+ years if pre-1900 or 45+ years after that.

Thanks, an excellent article. A key detail of global warming due to combustion is that the CO2 carbon dioxide molecule generated is a greenhouse gas whereas the source O2 oxygen molecule consumed by combustion is not.

Most of the observations were made by telegraph clerks originally, e.g. in 1868 :

Daily rainfall for Southchurch in Essex for 1852. Nearly all dry days from the start of March (and even back into February) to May 10th.

Her daily readings are part of the enormous set of daily rainfall sheets scanned in by the Met Office archive last year, e.g. Honingham Hall, Norfolk for 1885:

Your image is from the Roy Military map though ?

One other misread: February 1943 4.44 should be 4.74

Records from Civil Engineers might also turn up. A few months ago I came across monthly rainfall figures for 1852 (and sometimes nearby years and daily figures) from about 20 Irish sites quoted in the Drainage section the 1853 'Board of Public Works Ireland' report.

Something like this (Textract's text/numbers, I put the grid together)

I got something similar using a screenshot of your image, but only right-to-left reversed, not top-to-bottom. I tried again with just the top-left part of the table (Day 1-10 and hour 1 to Noon) and it comes out sensibly, so I think the full image has overwhelmed it.

I think the Textract results have swapped top and bottom, and possibly left and right too ? UOON on the bottom row is Noon in table heading row. The 'qui' values are the 'mb' s
