Temperatures for the contiguous U.S. are based on data from the U.S. Historical Climatology Network Version 2 (Menne et al., 2008). Temperatures for Alaska, Hawaii, and Puerto Rico are based on data from the Cooperative Observers Network adjusted to remove non-climatic influences such as changes in instruments and observer practices and changes in the station environment (Menne and Williams, 2008). U.S. time series on page 27 is calculated with data for the contiguous U.S., Alaska, and Hawaii. U.S. map on page 28 lower left includes observed temperature change in Puerto Rico. Winter temperature trend map in the agriculture section, page 76, is for the contiguous U.S. only. References for this endnote: Menne, M.J., C.N. Williams, and R.S.
