What is it about the Gravesend site that makes it so warm?

The London MO is at least understandable, being in the middle of a heat
island.

Not 100% sure where the Gravesend site is, but the high readings could be
due in part to it being an urban site.

I think that the "Gravesend" site is not in Gravesend itself but somewhere
out on the Broadness peninsula, near the River Thames north of Swanscombe.
Not exactly an urban site, but I would appreciate more details as would, I
believe, many readers of the NG.

I seem to remember that PE believes that it is suspect, but whether that is
because of the frequency with which its readings appear in the high
temperature records or not, I do not know. Over to you, please, Philip!

The Gravesend (so-called) site is, as you say, on Swanscombe
Marshes, not far from the Thames. The Grid Reference is TQ 605766.
See http://www.ordnancesurvey.co.uk/oswebsite/getamap/
It is nearly a mile from the nearest large building (to the south
and southeast) but is very close to a tall radio mast which is said to
afford it some shelter, quite how I don't know. It does produce high
max's but this should not in itself disqualify it. I can't see
anything wrong with the site myself but more informed opinion may
differ.
