Interesting to see when Mann et al will become aware of this, the impulse response of lowpassmin.m is quite longer than in the hadcrut smoothing case..

I’ve been trying to familiarize myself with the inner workings of SSA. It looks like there may be some useful aspects of the methodology, but I’m not sure that smoothing as done by the team is necessarily one of them.

Original Matlab version also now available at
http://data.climateaudit.org/scripts/rahmstorf/

Note my other comment showing that the Rahmstorf huffing and puffing merely ends up yielding a triangular filter.

I can’t seem to locate ssatrend.m with google. Any hints as to where it might be available?

R version here now: http://data.climateaudit.org/scripts/rahmstorf/functions.rahmstorf.txt

Jean S wrote about m-version here (comment #15495)

Need to try #54 with M=15, as that value seems topical now ;)
