    • Global Historical Climatology Network (GHCN) Monthly Precipitation, Version 4

    Metadata Updated: September 1, 2024

    The Global Historical Climatology Network (GHCN) Monthly Precipitation, Version 4 is a collection of worldwide monthly precipitation values with measurement, quality control, and source flags for global locations. Values are in tenths of a millimeter and coverage is mostly global land masses with voids as expected in less populated areas. It offers significant enhancements over the previous version 2. It contains more values both historically and for the most recent months. Its methods for merging records and quality control have been modernized. It is used by the National Centers for Environmental Information (NCEI) to put recent months' precipitation into a historical context. The data set is updated each month and available through NCEI's data access portal.
