Its not bad but I can tell straight away there a few ommisions just in
Cumbria. ( private and meto sites)

The Met Office have a good link of their stations, updated last year
and my station is on the map as Brampton No3, not sure what happened
to 1 and 2 !

Normally Met Office climat or rainfall sites will be numbered if there
are minor site moves over time, or different instruments are in use -
so often rainfall sites can be 'XYZ', 'XYZ No. 2' etc. and a pre-
existing rainfall station 'upgraded' into a climate site will normally
pick up the existing name including 'No. x'. Did you have an earlier
rainfall site by any chance? If not, there may have been earlier
rainfall or perhaps even climat records made in Brampton which may
have been confused with your current records if just the name was used
for the 'new' site.

As I recall, the policy  regarding same/close sites was that the sites
retained the name and were numbered where the record was felt likely
to be homogeneous - although of course sometimes any change would not
be apparent until some time afterwards - but if the site move was
significant or homogeneity was/was likely to be affected, then the
site name was changed - so you could have (for example) 'Newtown' and
'Newtown, University' (which is more specific and durable than 'new
site'). Sometimes this was done retrospectively with long records when
being examined for homogeneity, urban effects etc. Exceptions were
occasionally made for airfields where the site name tended to remain
the same (the site at Heathrow has moved several times since it
started records in 1946, for example, yet all the records are
consolidated as 'Heathrow').

I should say that the version currently online is showing its age now
and hasn't had a proper update and makeover for quite a while - it
actually ends up being a surprisingly large drain on time and effort
to keep this sort of map accurate and fully up to date. However, the
good news is that there is a new version actively in preparation, but
which probably won't be ready for at least another 2-3 weeks. I'll
post a note here when the new version goes online.

More generally, it is always difficult to know which stations to place
on such a map. There are now probably and at a rough guess 500-1000
UK-based AWS stations that are set up to upload data to the web
(although at any one time the number of active stations is smaller for
various reasons, eg school-based stations often go offline during
holidays; private stations often seem to encounter upload problems
etc)

There is a temptation to try and categorise the stations as to data
quality. Personally I'm not not convinced of the value of uploading
data that is clearly less than ideal in quality eg because of poor
sensor exposure or accuracy, but it would be a huge and unrewarding
job trying to categorise every station according to its data quality
and anyway some users seem to derive a lot of satisfaction from having
successfully met the technical challenge of setting up an online AWS
even if data quality is sometimes relegated to secondary importance.
(Though perhaps there is scope for stations to apply for something
like a COL grading if they wished to and these could be shown in a
distinctive way on a map).

Then there are several other networks of course with publicly viewable
data like Weather Underground, AWEKAS, the various Weather Display
related projects such as the 'Mesomap', the new Davis Weatherlink
(worldwide) website with contributions only at present from 6555 IP
loggers at www.weatherlink.com (see the Map option and zoom in on the
UK) and various others.

But not clickable links, unlike the other one.

I noticed that.

If only I had the budget to follow suit... (sigh)
