Measuring Precipitation on Willis' Boots

Willis writes in with latest FOI refusal from CRU, saying that they are unable to provide a list of the sites used in HadCRU3.

A Try for Thompson Data at PNAS

The recent success in getting at least some data from Phil Jones – which he had obstructed since my original request in 2003 – has caused me to refresh my attempts to get Lonnie Thompson to archive his data so that the scandalous inconsistencies between different versions can finally be appraised. Last year, he published […]

Loso: Varves in Alaska

I said that I post the graphic from Loso et al if someone sent it to me today. In fact, Loso et al is online here and interested parties can consult it for themselves. I don’t have time to comment on this study other than very briefly, but here are some of the key graphics.

FOI: The “Final” Answer on Jones et al 1990

I wrote again on Apr 17, 2007 on my FOI request observing that part (B) of my FOI request had not been answered: the identification of the stations used as comparanda in the calculations of Jones et al 1990. Thank you for your courtesy and attention in this matter, which has successfully resolved part (A) […]

Inversions from Partial Correlation Coefficients

Willis raised an interesting point about trying to invert series based on partial correlation coefficients with monthly temperatures. His post, together with UC’s response are collected here.

More North American Upper Treeline: Wilson-Luckman 2002, 2003

In our continuing quest for a North American upper treeline chronology that exemplifies the IPCC AR4 claim that additional data since TAR shows “coherent behavior” across multiple indicators, we turn now to the upper treeline proxies of Wilson and Luckman, 2002, 2003. They collected 20 Engelmann spruce sites in British Columbia in 1998, which together […]

Recyclable AbathyThermograph Instruments

Lyman et al have had to correct their paper on ocean cooling, as the effect that they observed has proved to derive in part from a bias from “Xpendable Bathy Thermograph (XBT) instruments”. They report The rapid decrease in globally integrated upper (0—750 m) ocean heat content anomalies (OHCA) between 2003 and 2005 reported by […]

CRU on Rural Data Exclusion

In their “explanation” of why Chinese rural data is not included in CRU, Jones says: None of the rural data (because of the annual resolution) entered subsequent versions of the Climatic Research Unit temperature database. This is obviously untrue as the “rural” sites in TR055 from which the Jones et al data derived had the […]

Reading a Thermometer

One of our readers asked how it was to read a thermometer. I’ve got a slightly different question: if I can locate daily maximum and minimum readings for Dulan airport on the internet, why can’t NOAA? This is not as trivial a point as it might seem, as it turns out that Dulan airport is […]
