Hi Tim, A new (available file). It should fix the negative excessions, and I have a hunch that it might fix the means too. You see, I noticed that the mean differences were all negative.. you can probably guess the rest, given the other fixes I've just made! ... The hot spike in Guatemala SON has been removed in the new version. That looks much better.
... hot spikes in France, Italy and Austria in JJA in 2003 have been reduce slightly too. Not sure if this is right or not ... Could Jul & Aug 2003 have been so hot that some observations validly did exceed the +3SD outlier check?
There are various other erroneous hot spikes that have now been correctly removed ... ... there are some cold spikes in both previous and latest 2008 updates... Have you turned on only outlier checking for +3SD, and not for -3SD? There are some early 20th century differences that I'm not too bothered about, though it would be nice to know why they arise. ... It's very worrying, as they really should be ~identical! Normals are read from the original (sacrosanct) climatology files so they shouldn't have changed at all.”
(1) hot spikes have been corrected. (2) cold spikes still there.
