Wow, Norman. Another really low sunshine figure. 40 hours so far in Copley.
Is your recorder well exposed or quite sheltered? Difficult to compare
sunshine as some have their electronic recorders on the top of tall masts to
catch every bit of sun. My Campbell Stokes is, obviously, at a more
realistic height of four feet above the ground. Ken Copley Teesdale
The recorder is pretty well exposed. It's at about 8 ft above ground, totally
open from N through E, SE and S to WSW. The only limitation is that, due to
the rising ground to the W and NW, we lose the last 45 minutes or so of
sunshine towards sunset except in the winter months. That's if it's sunny, of
course, which it isn't very often in late afternoon. Overall, I think my
sunshine figures are a very good representation of the sunshine that we get
here. I have checked the recorder and it does record 60 minutes sunshine
during an hour with unbroken sun so I have no doubt about its reliability. As
long as there are shadows it does respond. This is not a sunworshiper's
paradise!

Just done a bit of checking. The COL station at Middleton, about 25 km SE of
here, has an annual average of 1151 hours which is 20% higher than my average.
Buxton, about 10 km WSW of here, had an annual average of 1133 hours during the
period 1931-1960. That's 18% above my average. So, perhaps our loss of sunshine
in the late afternoons due to the lie of the land is a bit more significant
than I thought or perhaps this is just a particularly un-sunny place.
