Monthly Summaries of the Global Historical Climatology Network - Daily (GHCN-D)

Monthly Summaries

Monthly Summaries of Global Historical Climatology Network (GHCN)-Daily is a dataset derived from GHCN-Daily. The data are produced by computing simple averages or monthly accumulations of the daily observations. The meteorological elements calculated for the data set include, but are not limited to: monthly maximum and minimum temperature, monthly precipitation (i.e., rainfall and snow water equivalent), snowfall and snow depth. Users of these monthly summaries have access to simple meteorological summaries for tens of thousands of stations worldwide.

Users must cite this data as: Monthly Summaries of the Global Historical Climatology Network - Daily (GHCN-D). [indicate subset used]. NOAA National Climatic Data Center. [access date].

General Documentation
  • Monthly Summaries Landing Page
    Monthly summaries provides monthly averages and extremes of temperature and precipitation (where these elements are observed) using global daily station data. The data are computed using observations from World Meteorological Organization, Cooperative, and CoCoRaHS networks.

Lineage StatementValues are simple averages or monthly accumulations calculated from the GHCN-D dataset. For more information, please review documentation associated with the dataset.
Processing Steps
  • NOAA created the National Centers for Environmental Information (NCEI) by merging NOAA's National Climatic Data Center (NCDC), National Geophysical Data Center (NGDC), and National Oceanographic Data Center (NODC), including the National Coastal Data Development Center (NCDDC), per the Consolidated and Further Continuing Appropriations Act, 2015, Public Law 113-235. NCEI launched publicly on April 22, 2015.
