Barabinsk, Russia 57N, 77E

I’ve been going through the process of reconciling gridded data and station data in one Russian gridcell. Most of my effort to date has been spent on creating tools for accessing and collating data archives into organized time series formats so that others don’t have to go through the same trials and tribulations of sorting […]

Gridcell 62N, 77E: Tarko-Sale, Russia

Today I’m going to discuss another Russian gridcell 62.5N; 77.5E, which is one of the gridcells that was identified by IPCC as having a particularly strong trend . Warwick Hughes previously analyzed this cell because of this here, with this map highlighting the location of the Tarko-Sale gridcell in the top left corner of the […]

Malye Karmakuly, Russia (#2)

Since I’ve been able to closely replicate one HadCRU3 gridcell from GHCN v2 data, it’s interesting to compare other HadCRU3 gridcells to GHCN versions. I’ve looked through a number of gridcells and each one has its own issues. Today, I’ll do a comparison of Malye Karmakuly, Novaya Zemlya, which we’ve discussed before, and the corresponding […]

Phil Jones and the Kazakh Copper Smelter (47N 67E)

Before I get to Phil Jones and the Kazakh copper smelter, I wish to report that, somewhat to my own amazement, I’ve been able to get a surprisingly close approximation of a few HadCRUT3 gridcells from third-party data. Here is a comparison of the annualized HadCRUT3 gridcell 47N;67E as compared to GHCN v2 for Karsakpay […]

Phil Jones and the Great Leap Forward

The other key network in the seminal Jones et al 1990 on urbanization (relied upon in AR4) is their Chinese network. The idea that China between 1954 and 1983 – the age of Chairman Mao and the Great Leap Forward – could have achieved consistency in temperature measurement that eluded the U.S. observing system (with […]

Phil Jones and the Dutiful Comrades

Beneath the seemingly placid world of U.S. weather co-operatives, recent analysts have found a turbulent world of changing observation times, with regime change after regime change. Hansen and Karl have been forced – unwillingly, I’m sure – to adjust past temperatures downwards. In contrast to the seemingly almost Iraqian chaos of the U.S. weather observation […]

Jones and the Russian UHI

A couple of years ago, before I got involved in proxy studies, I was interested in the UHI question and wrote to Phil Jones to request the data used in Jones et al 1990, his study purporting to show the unimportance of urban warming. Jones said that it was on a diskette somewhere and too […]
