NB: the station numbers have an additional '0' appended, thus Heathrow

But these aren't raw data; they're monthly means! They've
already been heavily manipulated. Surely if these people
ask for the raw data, they should be supplied with
them ... that is, the raw observations, hourly or half-hourly,
latterly 1-minute or 5-minute logged obs, including all the other
elements. Should fill several warehouses, I reckon. Might keep
