Temperature, Precipitation, and Drought

Temperature, precipitation, and drought data and products

National

  • Alaska Statewide Anomalies
    Alaska statewide temperature and precipitation anomalies, derived from a coarse gridding of GHCN-Monthly data.
  • ASOS Temperature Departure & Degree Day Maps
    Daily updates of temperature and precipitation versus normal for several hundred U.S. automated stations, including Alaska and Hawaii. Users can loop these images through a multi-day animation.
  • Climatological Rankings
    Monthly U.S., Statewide, Divisional, and Regional 1-12, 18, 24, 36, 48, 60-month, and Year-to-Date Temperature, Precipitation, Degree Days, and Palmer (Drought) Rankings
  • National Temperature Index
    Several different methodologies to estimate the temperature history of the contiguous United States, including NCDC's current operational version. Users can graph, compare and save the output from these different methods.
  • National Temperature and Precipitation Maps
    Current, 3-Month, 6-Month, 12-Month, and Year-to-Date National, Divisional, Statewide, and Regional Temperature and Precipitation Rank Maps
  • Time Series Plots
    Climate at a Glance: U.S. temperature, precipitation, and drought time series
  • U.S. Percentage Areas (Very Warm/Cold, Very Wet/Dry)
    This product shows, for each month, season and year since 1895, how much of the contiguous United States experienced extreme (top or bottom 10%) temperature and precipitation conditions.
  • Weekly Divisional Products
    Maps of weekly temperature and precipitation anomalies, and short term Palmer drought indices are produced from CPC data.
  • Statewide Temperatures
    State annual and seasonal time series and decadal average temperature maps

Global

  • Global Temp & Precip Maps
    Monthly, Seasonal, and Annual Global Temperature, Precipitation, and Extremes Maps
  • Global Surface Temperature Anomalies
    • Time Series Plots
      Climate at a Glance: global temperature anomalies time series
    • FAQ
      The Merged Land & Ocean Surface Temperature data are presented as anomalies (departures from a long-term average) on a five-degree by five-degree global grid. The period of record is January 1880 through the most recent month.
  • Upper Atmospheric Temperatures
    Temperature history for three different layers of the atmosphere: lower troposphere, middle troposphere, and lower stratosphere. These are different parts of the atmosphere than the more familiar surface temperature.
  • GHCN Gridded Products
    GHCN Monthly Global Gridded Temperature and Precipitation Products
