There seems to be some confusion (well at least I'm confused) about just
how warm January was.

Some reliable sites are giving a mean of 7.9C, e.g.

http://www.bbc.co.uk/weather/feeds/35234711

http://www.metoffice.gov.uk/climate/uk/summaries

but they do talk about the "UK mean", which I've never heard mentioned
before, and if I have, I always assumed they just meant the CET
temperature (which is a bit like PIN number I know).

On the other hand other pages give a CET of 9.7C:

http://www.metoffice.gov.uk/hadobs/h..._mean2015.html

which is ridiculously high. I at first assumed it was a typo for 7.9, but
others are assuring me not.

Anyway in the know like to clarify it for me please?


The MetO calculate regional and UK means using the scanned/digitised records
right back to 1910. Why 1910 - haven't a clue, but I suspect it is as far
back as the funding allowed them to do it. The CET is a totally different
animal.
