I know I've been there before ,but the temp.in my fully exposed Stevenson
screen is currently 11C but the Davies on the shady side of the house is
8.3C !.
Obviuosly the screen must be the one noted for continuity,but it does rather
throw into doubt the validity of some of the other figures quoted elsewhere
at times don't we think ?

Where do you get hold of a Stevenson Screen?

Ron, I have run a Stevenson screen and a Davis passive radiation screen
next to each other (i.e. about 3 m apart) in an open and unobstructed
site for the past 18 months (and previously at my former site, 1 km
away, for 9 months in 1997-98).

The SS tends to be a little warmer by day, particularly in strong
sunshine and light winds, but rarely by more than 0.8 degC or so even
in midsummer. I suspect a 3 degC difference owes more to one being in
deep shade and the other in open sunshine ...

Trevor,

Got mine from www.met-check.co.uk (01296 7122354)

Made well enough, but the paint was a bit thin - put an extra coat on

But why are they so bloody expensive? I don't see why they should cost
more than, say £100.

Agree, they suppliers would argue the turnover is small.

The iron stand was poor. Came painted, but after just 2 weeks in the salty
sea air it was starting to rust, so had to paint that as well.

My 1stt Stevenson Screen was bought as a kit, which you had to paint & put
together, time consuming but it lasted 25 years. This one's a year old,
interesting to see how well it will last. You can't get kits anymore (as far
as I'm aware).

That's sad Graham ,if the kits are no longer available,like you I built mine
from a kit 25 years ago,and its still going strong .Can't see any reason why
it won't go on for ever providing its kept well painted,mind it was a bugger
to paint originally,all those slats three coats !, .had to spread it out
all over the lawn on newspaper,much to the disapproval of the boss.....

I used the spare bedroom to lay out and paint mine. The screen lasted from
1977 to 2004, by which time it was starting to rot quite badly.

So the sea air is now rustproof?
