Monthly CET on Hadley Centre's pages
 

Is it my imagination, or have they removed every reference
to monthly CET after December 2003? Some of us
pointed out a large and very-difficult-to-explain jump in
their published CET (from 6.6ºC to 7.0ºC I think) for
March 2004 some time ago, and I was trying to discover
whether they had reverted to the much more reasonable
earlier figure yet, but it's now vanished. (My own calculation
had put it at 6.55ºC). I see that Met Office's monthly
summary page retains a CET of 6.6ºC for March.
