On ‘denying’ Hockey Sticks, USHCN data, and all that – part 2

In part one of this essay which you can see here, I got quite a lot of feedback on both sides of the climate debate. Some people thought that I was spot on with criticisms while others thought I had sold my soul to the devil of climate change. It is an interesting life when…

NOAA shows ‘the pause’ in the U.S. surface temperature record over nearly a decade

NOTE: significant updates have been made, see below. After years of waiting, NOAA has finally made a monthly dataset on the U.S. Climate Reference Network available in a user friendly way via their recent web page upgrades. This data is from state-of-the-art ultra-reliable triple redundant weather stations placed on pristine environments. As a result, these…

NOAA’s ‘Janus moment’ – while claiming ‘The American public can be confident in NOAA’s long-standing surface temperature record’, they fund an experiment to investigate the effects of station siting and heat sinks/sources on temperature data

NOAA’s impersonation of the two faced god Janus just proved my point about station siting issues with their actions that speak louder than words. While there’s all this caterwauling about my PBS News hour interview, and my statements were apparently so threatening that NOAA itself asked PBS to publish a rebuttal in their apologetic story…

Errors in Estimating Mean Temperature – Part II

Guest post by Lance Wallace Last week (Aug 30), Anthony Watts posted my analysis of the errors in estimating true mean temperatures due to the use of the (Tmin+Tmax)/2 approach widely used in thousands of temperature measuring stations worldwide: http://wattsupwiththat.com/2012/08/30/errors-in-estimating-temperatures-using-the-average-of-tmax-and-tmin-analysis-of-the-uscrn-temperature-stations/ . The errors were determined using the 125 stations in NOAA’s recently-established US Climate Reference…

Errors in Estimating Temperatures Using the Average of Tmax and Tmin—Analysis of the USCRN Temperature Stations

Guest post by Lance Wallace Abstract The traditional estimate of temperature at measuring stations has been to average the highest (Tmax) and lowest (Tmin) daily measurements. This leads to error in estimating the true mean temperature. What is the magnitude of this error and how does it depend on geographic and climatic variables? The US…

An ‘inconvenient result’ – July 2012 not a record breaker according to data from the new NOAA/NCDC U.S. Climate Reference Network

I decided to do myself something that so far NOAA has refused to do: give a CONUS average temperature for the United States from the new ‘state of the art’ United States Climate Reference Network (USCRN). After spending millions of dollars to put in this new network from 2002 to 2008, they are still giving…
