Global Historical Climatology Network - Daily (GHCN-Daily), Version 3

Daily Summaries

browse graphicMap of GHCNd stations
The Global Historical Climatology Network - Daily (GHCN-Daily/GHCNd) dataset integrates daily climate observations from approximately 30 different data sources. Version 3 was released in September 2012 with the addition of data from two additional station networks. Changes to the processing system associated with the version 3 release also allowed for updates to occur 7 days a week rather than only on most weekdays. Version 3 contains station-based measurements from well over 90,000 land-based stations worldwide, about two thirds of which are for precipitation measurement only. Other meteorological elements include, but are not limited to, daily maximum and minimum temperature, temperature at the time of observation, snowfall and snow depth. Over 25,000 stations are regularly updated with observations from within roughly the last month. The dataset is also routinely reconstructed (usually every week) from its roughly 30 data sources to ensure that GHCNd is generally in sync with its growing list of constituent sources. During this process, quality assurance checks are applied to the full dataset. Where possible, GHCNd station data are also updated daily from a variety of data streams. Station values for each daily update also undergo a suite of quality checks.

Data Update Frequency Daily
PurposeGlobal Historical Climate Network includes daily land surface observations from around the world. The GHCNd was developed to meet the needs of climate analysis and monitoring studies that require data at a sub-monthly time resolution (e.g., assessments of the frequency of heavy rainfall, heat wave duration, etc.). The dataset includes observations from World Meteorological Organization, Cooperative, and CoCoRaHS networks. If observed, the station dataset includes max and minimum temperatures, total precipitation, snowfall, and depth of snow on ground. Some U.S. station data are typically delayed only 24 hours.
Use Limitations
  • The dataset cannot be used to quantify all aspects of climate variability and change without any additional processing. In general, the stations providing daily observations were not managed to meet the desired standards for climate monitoring. Rather, the stations were deployed to meet the demands of agriculture, hydrology, weather forecasting, aviation, etc. GHCNd data have not been homogenized to account for the potential artifacts associated with the various reporting practices at stations. Users must consider whether the potential for changes in systematic bias might be important for their particular application.

Processing Steps
  • The process of integrating data from multiple sources into the GHCNd dataset takes place in three steps: 1) screening the source data for stations whose identity is unknown or questionable; 2) classifying each station in a source dataset either as one that is already represented in GHCNd or as a new site; and 3) mingling the data from the different sources.
    Rationale: The first two integration steps are performed whenever a new source dataset or additional stations become available, while the actual mingling of data is part of the automated processing that creates GHCNd on a regular basis.
  • During each reprocessing cycle, the data are first passed through a "format checking program" that looks for problems such as impossible months or days, invalid characters in data fields, etc.
    Rationale: The primary purpose of the QC program is to ensure that the data integration procedures do not either introduce or retain records that violate the intended and documented GHCNd data format.
