Layer: Change in Unusually Cold Temperatures in the Contiguous 48 States, 1948–2020 (ID: 1)

Name: Change in Unusually Cold Temperatures in the Contiguous 48 States, 1948–2020

Display Field: Station

Type: Feature Layer

Geometry Type: esriGeometryPoint

Description: This map shows trends in unusually cold temperatures at individual weather stations that have operated consistently since 1948. In this case, the term "unusually cold" refers to a daily minimum temperature that is colder than the 5th percentile temperature during the 1948–2016 period. Thus, the minimum temperature on a particular day at a particular station would be considered “unusually cold” if it falls within the coldest 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 colder than the 5th percentile. Blue upward-pointing symbols show where these unusually cold days are becoming more common. Red downward-pointing symbols show where unusually cold days are becoming less common. For more information:
