Hi UC,

Do you have the papers Thom (1954) “THE RATIONAL RELATIONSHIP BETWEEN HEATING DEGREE DAYS AND TEMPERATURE” and Thom (1966) “NORMAL DEGREE DAYS ABOVE ANY BASE BY THE UNIVERSAL TRUNCATION COEFFICIENT”?

I just got them and they seem to have the very basic statistical model used to calculate monthly station temperature means that Jones implicitly assumes in all his papers, and that forms the basis for the USHCN series. If you don’t have them, and would like pdf copies, drop me a line by email.
