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…

Siting related temperature bias at the Dutch Meteorological Institute (KNMI)

“This a complicating factor for the homogenization of daily temperature series.” WUWT first reported on the issues with the KNMI De Bilt weather station in October 2009 here. About that time, Dr. Pielke Sr. and I were given access to a KNMI preliminary report on the siting and subsequent bias problems at De Bilt, but…
