(Relative) Extreme Temperature Events

Project Information:

As part of a NOAA-funded grant to examine trends in a variety of different factors that relate to human thermal comfort, we developed four metrics based upon the Nairn and Fawcett (2014) idea of an Excess Heat Factor:

  • Extreme Heat Events (EHE)
  • Extreme Cold Events (ECE)
  • Relative Extreme Heat Events (REHE)
  • Realtive Extreme Cold Events (RECE)
