Hadley Centre Central England Temperature (HadCET) dataset + DMI+ NOAH The CET dataset represents the world’s longest continuous instrumental temperature record. Danish temperature data have been superimposed for comparison. The earliest Danish measurements were taken from the top of the Round Tower in Copenhagen and subsequently converted to a national average, with an estimated uncertainty of ±0.5 °C. Also shown are global temperature values from NOAA (National Oceanic and Atmospheric Administration), adjusted by adding 13.7 °C (the IPCC’s assumed preindustrial average) plus global anomaly for 1980 +0.51 °C, resulting in an approxima...
