Homogenization of Temperature Data: An Assessment

Kevin Cowtan


The retrospective calibration, or homogenization, or historical temperature records has recently been questioned in the public discourse on climate change. In this report I re-examine the underlying assumptions and reproduce most of the relevant results. More importantly, I document each step and provide all of the computer code, so that citizen scientists with the appropriate skills can reproduce and extend my results.

This web site provides material relating to the report "Homogenization of Temperature Data: An Assessment".
