GISS does not provide a coherent archive of station data (such as is available at GHCN.) As reported before, Nicholas developed a technique for downloading station data within R. Downloading the entire data set (which takes a minute or so from GHCN on a highspeed network) is laborious but automatic. I did this in the […]
D’Arrigo, Wilson et al 2007 is an interesting article on the Divergence Problem, about which I plan to post from time to time. Since we’ve been discussing temperature data recently – with special discussions of GHCN data problems in Russia, China and Australia, I thought that it would be interesting to draw attention to an […]
It’s pretty amazing to see how enthusiastic climate scientists have been in checking the information in Swindle as compared with their virtually complete acquiescence with Inconvenient Truth. I guess it depends whose ox is being gored. Since we’ve been looking at gridcell issues, I took a look at the temperature graphic in Swindle which has […]
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 […]
GISS has a large collection of station data, both adjusted and unadjusted. Unlike many data archives, GISS do not permit you to either extract the entire data set from a single archive or from permanent individual files. You can obtain digital data for individual stations, but you have to go through a laborious process of […]
I made a subset of HadCRU3 to cover the continental U.S. and compared it to the USHCN-2000 version.
Although the USHCN version used in Hansen’s 1999 press release seems to be expunged from official U.S. government records, it was fortunately preserved by John Daly. Jerry Brennan sent me a link to a version preserved by John Daly yesterday, from which I was able to replicate the version in the 1999 press release, as […]
According to the National Climatic Data Center (NCDC),, covered here, a new Beta version of the U.S. Historical Climatology Network will be released next year. They say that the new data set uses “recent scientific advances that better address uncertainties in the instrumental record. Because different algorithms were used in making adjustments to the station […]
Another interesting post from Willis: James Hansen of NASA has a strong defense of model reliability here In this paper, he argues that the model predictions which have been made were in fact skillful (although he doesn’t use that word.) In support of this, he shows the following figure: (Original caption)Fig. 1: Climate model calculations […]
