Comparison of Temperature Trends Using an Unperturbed Subset of The U.S. Historical Climatology Network

Paper finds temperature trend estimates vary according to site classification, with poor siting leading to an overestimate of minimum temperature trends and an underestimate of maximum temperature trends.

Paper finds temperature trend estimates vary according to site classification, with poor siting leading to an overestimate of minimum temperature trends and an underestimate of maximum temperature trends. The temperature trend measured by unbiased ground based weather stations in the National Oceanic and Atmospheric Administration’s (NOAA) Historical Climatology Network (HCN) were just two thirds as strong as NOAA’s official temperature trends.
