Various records of and trends in extreme weather
- U.S. Climate Extremes Index (CEI) — The U.S. Climate Extremes Index (CEI) was developed to quantify observed changes in climate within the contiguous United States. Time series graphs and data files of the CEI (from 1910 to the present) are available for the following periods: Annual, Spring, Summer, Autumn, Winter, Cold Season, Warm Season and Hurricane Season. Elements included in the index include: Temperature, Precipitation and PDSI.
- National Climate Extremes Committee (NCEC) — Established in 1997 the NCEC's main goal is to assess the scientific merit of extreme climatological/meteorological events.
- U.S. State Climate Extremes Committee (SCEC) — The State Climate Extremes Committee (SCEC) was created in 2006 in response to the need for proper and comprehensive evaluation of meteorological observations which may have tied or exceeded existing statewide all-time record values.
- U.S. Climate Extremes — Locations and values of climatological extremes in the U.S.
- U.S. Streaks — Stations that experience consecutive days with temperature/precipitation values which exceed or fall short of various thresholds
- U.S. Billion-Dollar Weather and Climate Disasters — Information and interactive tools on economic losses, deaths, and other impacts for U.S. weather and climate disasters where overall damages/costs reached or exceeded $1 billion
- U.S. Records — Daily Weather Record tool built using climate and weather data from Climate Data Online (CDO)
