Can anyone tell me if there is an average thickness value for each
month
here in the UK?

and I wrote:
Treat these
figures as a good guide without being gospel (fairly happy with a +/-
1 dam possible error).

1961-1990 [dam]
Jan/Feb Jul/Aug
Aberdeen area: 529 552
London area: 533 558
[ 'corrected/amended' ... see below ]

I have now ploughed through the data available on the NOAA-CIRES Climate
Diagnostics Centre site
(http://www.cdc.noaa.gov/) :
I'm not quite clear what averaging period was used though the
implication is that it runs from:- 1968 to 1996, though elsewhere on the
site, different periods are used. However, it looks as if my figures
could do with a little amending, and I have also extracted monthly mean
thickness values for a point roughly in the middle of the CET 'triangle'
..... see below.

1968-1996 [dam]
Jan/Feb Jul/Aug
Aberdeen area: 531 552(u/c)
London area: 534 557

And for a notional point within the CET domain (see:-
http://www.metoffice.gov.uk/research...sdata/cet.html )

JAN 535
FEB 534
MAR 535
APR 538
MAY 544
JUN 551
JUL 555
AUG 556
SEP 552
OCT 548
NOV 541
DEC 538
