Layer: Change in Unusually Hot Temperatures in the Contiguous 48 States, 1948–2016 (ID: 0)

Name: Change in Unusually Hot Temperatures in the Contiguous 48 States, 1948–2016

Display Field: Station

Type: Feature Layer

Geometry Type: esriGeometryPoint

Description: This map shows trends in unusually hot 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 1948–2016 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 1948–2016 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:
