Are you just interpreting the maps, Julian, or are there some figures
for Mickleham that I can not see?


I am afraid that I was merely interpreting the maps Ken (looking closely,
guessing locations; not too difficult as the input to the maps will be the
climat. and synoptic stations). I can't even quote any averages for the site as
my 30 aves. booklet is at work. Thank goodness some met. stations are in the
bottom of dry valleys, though doubtless Chipstead valley - and probably other
sites - are more extreme. A colleague who lives very nearby has a distinctly
frosty back garden.

Further browsing reveals that sometimes when you request a ground frost map you
receive an air frost map. Overall though, probably the best feature on the M O
website yet.
