Title: Change in Unusually Hot and Cold Temperatures in the Contiguous 48 States, 1948-2015
Abstract: This map shows trends in unusually hot and cold temperatures at individual weather stations that have operated consistently since 1948. In this case, the term “unusually hot” refers to a daily maximum temperature that is hotter than the 95th percentile temperature during the 1948–2015 period. Thus, the maximum temperature on a particular day at a particular station would be considered “unusually hot” if it falls within the warmest 5 percent of measurements at that station during the 1948–2015 period. The map shows changes in the total number of days per year that were hotter than the 95th percentile. Red upward-pointing symbols show where these unusually hot days are becoming more common. Blue downward-pointing symbols show where unusually hot days are becoming less common. For more information: www.epa.gov/climatechange/science/indicators
Purpose: These data were created to be used for the U.S. Environmental Protection Agency's Climate Change Indicators in the United States.
