If you look my blog I've done just that, but that's not using rainfall from
a 'real' site but is a composite value made up from many sites in a region.
What I really would like is daily values for a site in the SW that extends
back at least 40 years or more.

Its quite obvious from the lack of response that no one has a long period
rainfall record or seems to know of one which is a pity.

==============

Bruce I have an ongoing project to look into climate change over Dartmoor
that will involve extracting rainfall data for Princetown from British
Rainfall going back into the 19th Century. This work has been commissioned
so I have to take my time and do it properly and will be unable to release
results until it has been published. Have you read my paper on Extreme
Rainfalls in the Twentieth Century published many years ago in
Meteorological Applications? This work has been extended by Paul Davies in
the Met Office taking it into the 21st Century. The conclusion so far is
that there has been a steep increase during the 21st Century but nothing
sig. before then. The definition of extreme takes into account orographic,
frontal and convective with the rainfall depth exceeding a threshold
according to duration. The rainfalls *very roughly* are local 1:100 year
return period for frontal and orographic and 1:10000 year return period for
convective storms. I'm not entirely convinced that your more simple approach
will be robust enough, but good luck anyway. Let me know if you would like
to see some papers, I think I have them at home in computer format.
