I’ve calculated the trends for all 1221 USHCN stations after 1900 and plotted up the contour maps for the raw, time-of-observation adjusted and fully adjusted results. Pretty interesting results. Here’s the results for the “raw” data, the adjusted versions are shown below. Contour map of 20th century trends for 1221 USHCN stations – “raw” data. […]
Anthony Watts has three new sites: Lovelock, Electra and Fallon, and there’s something unexpected in them (Aside from the jet fighter discharging on the weather station – which is disappointing but almost expected by now.)
Anthony Watts has a couple more stations in hand (Electra and Fallon) about which I’ll comment later today. The detailed examination of USHCN stations fits into the prior debate initiated by the Davey and Pielke 2005 survey of sites in eastern Colorado. The original Davey and Pielke article was accompanied by an official response from […]
A CA reader has brought to our attention an interesting new article by Pielke Sr et al, Unresolved Issues with the Assessment of Multi-Decadal Global Land-Surface Temperature Trends, which disucsses microsite problems. There is a lengthy roster of co-authors: Roger A. Pielke Sr., Christopher A. Davey, Dev Niyogi, Souleymane Fall, and Jesse Steinweg-Woods, Ken Hubbard […]
I observed the other day that Eli Rabett had done a bait-and-switch, in which Eli showed a picture of a well-located new station at Niwot Ridge (started only in 2003) as a supposed refutation of criticisms of incinerators, barbecues and tennis courts at USHCN stations. In response, Eli observed his right to “carrot pick”. Rosanne […]
Karl and Hansen have condemned poor USHCN metadata and, perhaps anticipating the need for something like surfacestations.org, gave a stunning endorsement to dramatically improving the collection and dissemination of photographs and other detailed site information for U.S. weather stations. In a statement, they said: Are we making the measurements, collecting the data, and making it […]
Eli Rabett, a pseudonymous professor and blogger, fresh from simply inventing tittle-tattle about me (his fabricated story that my downloading of GISS data had “resulted in denial of service to everyone else”), has continued his descent with a bait-and-switch illustration of the supposed “Boulder station” in an effort to discredit the collection of microsite data […]
Anthony Watts announces the start-up of surfacestations.org, an effort to catalogue microsite information for weather stations used in the construction of surface temperature histories, an effort that is obviously highly worthwhile. Anthony: As many of you know from watching blog postings here, I have made it my mission to photograph, survey, and catalog every USHCN […]
The USHCN Station History Adjustment procedure is credited to Tom Karl in Karl and Williams 1987. Karl has been very prominent in the IPCC movement. That’s not to say that the potential adjustment is wrong or unjustified, but that the adjustment needs to be scrutinized with the same care as one would scrutinize an adjustment […]
I’ve plotted up some USHCN station information for the 18 sites closest to Susanville (why Susanville – it’s one of the Anthony Watts- Russ Steele sites that they happened to post on lately.) I’ve been reading Karl and Williams 1987 which sort of describes the USHCN Station History Adjustment method. I’ll talk about Karl and […]
