Penhalvean Climatological Station Data 1991-1999 - Stithians Weather Station, Stithians, Cornwall, UK

During the years from 1991-1999, Mr. Ashley Wood diligently recorded very comprehensive Climatological data as a voluntary co-operating observer for the Meteorological Office at his Penhalvean Farm weather station. He did not want all of his hard work to go to waste and be lost forever. So, with this in mind, he kindly arranged to pass all of his recorded data on to me (via Mr. Phil Blease, who is the Chairman of Stithians Parish Council) and these were handed to me by Phil on 7th October, 2020. I am very pleased to say that all of Ashley’s data is now fully digitised and has been added to our Stithians Weather website to ensure that it will be preserved forever for everyone to see!

The first to be added is a small explanatory pamphlet that is called ‘Instructions for Completing Monthly Returns on Metform 3208B’.

The full data for Penhalvean from1991-1999 then follows, month by month and year by year.
