It seems there is a new version of the Spencer and Christy MSU product out (see here; S+C must be about the only people that still allow directory listing on their web sites). This is a provisional product and its not clear that there is any great point in talking about it, especially when RSS is likely more reliable.
However, CA have picked it up and the usual nonsense flows out again… but the bit I want to pick out is the bizarre assertion (by McI, comment 19) that of “the cooperative approach of S&C”. As far as I know, no-one has seen their computer code [Oops: see uupdate]. RSS made a major correction to S+C in fixing a sign error for them (which S+C have still not explicitly admitted) but had to do this by back-engineering, since… their code wasn’t available. TP even explicitly asks if anyone has audited this stuff… but of course, no-one is interested in doing that, especially not McI.
[Update: a bit more interestingly, there is a new Fu+J in J Climate which basically says “we still think we’re right” -W]
[Uupdate: According to a Christy email published on CA, Christy did give some – perhaps the vital parts – of his code to RSS. I’m still curious about the time frames of all this, though -W]
