Climate at a Glance - Global Temperature Anomalies

Interactive global land and ocean temperature anomalies maps, available at the NOAA Climate at a Glance website, provide valuable illustrative data. The anomalies are based on 1981-2010 mean.

Where do these data come from?

Global temperature anomaly data come from the Global Historical Climatology Network-Monthly (GHCN-M) data set and International Comprehensive Ocean-Atmosphere Data Set (ICOADS). A combined global land and ocean temperature anomaly dataset was created from these resources.

  • What can I do with these maps?

    • Compare maps from January 1880 to present
    • Zoom into specific grid point to get data on that location

    How do I use the site?

    Select Monthly or Annual and use the pull-down menus to select the desired timeframe.

    Within the map, click on a 5° x 5° grid point to get more information about that location, including a Time Series.
