OK, so I got interested in decoding the binary data sets at ftp://data.giss.nasa.gov/pub/gistemp/download/ as well. Wrote some Perl to slice and dice the data set into various series. I now have fully 1.6Gb less free hard drive space and I cannot figure out where my Sunday went :-)
I’ll tidy up the various scripts and post on my web site when I get a chance. The result of my attempt at visualizing TSurf1200 and SSTHadR2 combined is available on Google Video.
