Hey, NOAA, if you’re not too busy deleting data, you can drop in and say hello.
Because of the puzzles in trying to replicate the NOAA graphic from archived data, I’ve also tried to replicate the HadCRU plots from archived data. Hu McCulloch has criticized the highly inappropriate use of Mercator projections by climate scientists and, as an exercise, I figured out a fairly simple method of plotting these results in […]
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 […]
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. […]
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 meteo.ru and there was nothing wrong with it. Nor is there anything wrong at GHCN-Daily for stations reporting there. […]
Released today on the promised schedule are CRUTEM3 and HadCRUT3 for October 2008. October 2008 was in the top 8 crutem3 (0.517 deg C)and in the top 6 hadcru3 (0.440 deg C) Octobers. Because our collective eyes right now are fairly attuned to the colors of these grids and how changes in individual stations affect […]
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 […]
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 […]
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 […]
In the last few days, NASA has been forced to withdraw erroneous October temperature data. The NASA GISS site is down, but NASA spokesman Gavin Schmidt said at their blog outlet that “The processing algorithm worked fine.” Schmidt blamed the failure on defects in a product from a NASA supplier and expressed irritation that NASA […]
