Well, I found it. Eureka that is, but what I found was rather depressing. I visited the USHCN climate stations of record both old and new at Eureka, California on July 30th and I can’t decide which site is more out of compliance with sitings standards. The original location was on the 4th story roof […]
WMO guidelines state that weather stations should be at least 100 feet from paved areas. As we see the USHCN pictures unfold, we’re obviously seeing one site after another in non-compliance with this requirement, a point notably made in connection with Tucson (Univesity of Arizona) site, where the location was particularly gross, but the point […]
This is the climatological station of record for Odessa, Washington. It is at the residence of a COOP weather observer administered by NOAA. The photo was taken by surfacestations.org volunteer surveyor Bob Meyer. In addition to the proximity to the house and the asphalt being less than the 100 foot published NOAA standard, we have […]
Peterson 2003 stated: Contrary to generally accepted wisdom, no statistically significant impact of urbanization could be found in annual temperatures. Last week, Peterson sent me a list of the 289 sites used in this study, together with the classification into urban and rural. As I noted previously, there are many puzzles in the allocation of […]
I posted up the list of 289 sites from Peterson 2003 purporting to show that the difference between “urban” and rural sites was negligible. (See related posts here and here.) As noted before, the definition of “urban” includes such metropolises as Wahpeton ND and Hankinson ND. Cottage Grove 1S OR is classified as “urban”, while […]
Eli Rabett and Tamino have both advocated faith-based climate science in respect to USHCN and GISS adjustments. They say that the climate “professionals” know what they’re doing; yes, there are problems with siting and many sites do not meet even minimal compliance standards, but Hansen’s software is able to “fix” the defects in the surface […]
Continuation of Unthreaded #16
Peterson (2003) online here is an influential study cited by IPCC AR4 purporting to show that the urbanization effect is negligible. It concluded: Using satellite night-lights—derived urban/rural metadata, urban and rural temperatures from 289 stations in 40 clusters were compared using data from 1989 to 1991. Contrary to generally accepted wisdom, no statistically significant impact […]
Obviously the big issue in climate is the impact of 2 times CO2. While my own issues tend to be statistical, this site obviously attracts many readers who want to jump straight to discussion of thermodynamics and theories of atmospheric physics. Articles like G and T obviously inflame such tendencies. For some reason, people who […]
There’s been some recent discussion about how only rural stations have been used in the GISS analysis, and those rural stations are qualified by looking at night time DOD satellite photos, and doing a count of visible streetlights within a radius to quantify UHI potential or lack thereof. The “best” stations are labeled “lights=0” One […]
