      Geoff,

        I know you don't want me to send you something now. I mentioned ages
    ago (last year) about some work on the London UHI I'd been doing.
       Here is the paper. It's just been accepted for Weather. I've to make
    slight changes to the English, that have taken me 20 minutes.
       The bottom line is that there is no urban-related warming at St James Park
    since 1900. The paper quantifies what the UHI is, but it has got no worse
    since 1900.
       Make sure you're not saying anything to contradict this in the urban annex
    of your report.
      Chris and I are glad that Colin spotted the mistake with the change factors
    being slightly offset. Mistake has been there a while! Shouldn't
    make much difference to the WG maps/tables.
      When you've got some time ask me about wind!
    Cheers
    Phil
