Glenn McGregor: Data Archiving not required by the International Journal of Climatology

After nearly 2 months and several inquiries, the editor of the International Journal of Climatology has finally said that they do not require authors to provide supporting data. Given that funding agencies rely on academic journals to ensure that authors archive data (improperly abdicating their own responsibilities), the moral of this should be that the […]

Downloading KNMI Model Data

Lucia has been experimenting with model data downloaded from KNMI and I thought that I’d try to experiment with this a little from time to time. Unlike Benjamin Santer, Ph.D. of the U.S. federal Lawrence Livermore Labs, who refused to provide any assistance whatever in providing the data used in Santer et al, Geert Oldenburgh, […]

Santer and the 4 NOAA Coauthors

Apparently none of Santer’s four NOAA coauthors either received or sent any correspondence to Santer regarding the monthly data series used in Santer et al 2008. What a strange way to run a railroad.

Hello, Viet Nam!

Hey, NOAA, if you’re not too busy deleting data, you can drop in and say hello.

"Anomalous" in Finland

Occasionally, I’ve been criticized for spending too much time on NASA GISS. Since we aim to please even our severest critics, let’s spend a little time today on NOAA, which has just reported the second warmest October of all time. I downloaded the NOAA gridded data (who mercifully, in this case, at least use .gz […]

A Collation Utility for GISS dset1 and dset2

GISS has been providing a considerable amount of intermediate information on their results. Unfortunately, it’s been provided in binary format that is presumably suited for people who speak Fortran with a Unix accent. I presume that such people converse with one another in medieval Latin. It’s not very handy for people who use modern languages. […]

OK, What Caused the Problem?

Are you like me and a little puzzled as to exactly how the GHCN-GISS problem happened? GISS blamed their supplier (NOAA GHCN). Unfortunately NOAA’s been stone silent on the matter. I checked the Russian data at and there was nothing wrong with it. Nor is there anything wrong at GHCN-Daily for stations reporting there. […]

Should the Credibility Crunch Move to NOAA?

Some RC commenters are bemoaning the criticism that GISS is currently weathering. For example, Tamino: Although the error originated NOT with GISS but before numbers even got through their door, I’ve heard no cries for heads to roll at NOAA or NWS — just vicious attacks on GISS. As so often, Tamino simply makes stories […]

Memo to Gavin Schmidt

From: He Whose Name You are Not Allowed to Utter Gavin, you said: [Response: There are still (at least) four stations that have Oct data in place of september data but that didn’t report september data (Kirensk, Irkutsk, Bratsk, Erbogacen). I expect that the SEP=OCT check that NOAA did, just didn’t catch these. Still, this […]

Watch the Ball

NASA spokesman Gavin Schmidt announced at realclimate that Hansen et al had fixed the Russian (and elsewhere data), following corrections to the data made by their supplier (NOAA GHCN.) Even though errors of over 10 deg C had occurred over the world’s largest land mass, it only reduced GISS October temperature by 0.21 deg C […]
