The South Central Climate Adaptation Partnerships team developed a new tool to analyze minimum temperature variables

Graph titled Annual Count of Days less than or equal to 32 degrees F for the County(ies). The y axis is 'Days' (0-124). The x axis is 'Years' (1951-2023). Data from four counties are plotted, each showing a downward trend in the number of days over time.

The Southern Climate Impacts Planning Program (SCIPP), a Climate Adaptation Partnerships (CAP) team,  recently developed a new tool. The County-Level Minimum Temperature Explorer analyzes several variables related to minimum temperature in the contiguous U.S. from 1951 to the near present:

  • Freeze Days – number of days where the minimum temperature was less than or equal to 32°F.
  • Coldest Minimum Temperature – coldest county-wide minimum temperature annually.
  • Warmest Minimum Temperature – warmest county-wide minimum temperature annually.
  • Minimum Temperature Threshold – the number of days with greater than or equal to OR less than or equal to a user-defined temperature.

The tool can be used alongside SCIPP’s Temperature Trends Dashboard. It allows for five counties to be selected and compared at a time. As an example, the figure above shows Freeze Days for four counties within the SCIPP region. Analyzing minimum temperatures is important for understanding the impact of climate change. In many regions, minimum temperatures are changing more than local average and maximum temperatures. For more information about the methodology, datasets, and included variables, see the documentation tab of the tool.
