Canadian Forest Fire Weather Index (FWI)
Years of record
- N/A
Fire weather indices are used to quantify the meteorological conditions that can lead to fire ignition and spread. They are used to communicate fire danger levels to emergency and fire fighting management, as well as the public on short time scales, and also for understanding long-term changes in fire regimes or wildfire risk. Several fire weather indices exist, each…

GHCNDEX: Gridded Temperature and Precipitation Climate Extremes Indices (CLIMDEX data)
Years of record
- to
GHCNDEX provides gridded, station-based indices of temperature- and precipitation- related climate extremes. It is intended for climate change detection and attribution studies, climate model evaluation, and operational monitoring of extreme climatic events. Twenty-six indices, including daily maximum and minimum temperatures, number of frost days, maximum 1-day…

HadEX3: Gridded Temperature and Precipitation Climate Extremes Indices (CLIMDEX data)
Years of record
- to
HadEX3 provides gridded, station-based indices of temperature- and precipitation- related climate extremes and supersedes HadEX2. It is intended for global and continental climate monitoring, climate change detection and attribution studies and climate model evaluation. Twenty-nine indices, including daily maximum and minimum temperatures, number of frost days, maximum 1…

NOAA ThreadEx Long-term Station Extremes for America
Years of record
- to
ThreadEx is a data set of extreme daily temperature and precipitation values for 270 locations in the United States. For each day of the year at each station, ThreadEx provides the top 3 record high and low daily maximum temperatures, the top 3 record high and low daily minimum temperatures, the top 3 daily precipitation totals, along with the years the records were set…

U.S. Climate Extremes Index (CEI)
Years of record
- to
The U.S. Climate Extremes Index (CEI) was first presented in 1995 as a framework for quantifying observed changes in climate within the contiguous United States. At present, the CEI evaluates the percent area of extremes in the distribution of much above/below average (top/bottom 10% of occurrence) temperatures, precipitation, drought, and tropical cyclone wind…
