Global Historical Climatology Network - Monthly Temperature, Version 4 (BETA)

GHCN-M v4 Temperature

browse graphicGHCN-M v4 Station Map
**Only available as BETA release.** The GHCN-Monthly Temperature Version 4 dataset consists of monthly mean temperature - both raw and bias corrected data. A full operational release is planned for early 2018. The operational monthly mean temperature data remain available in version 3. The version 3 dataset also includes monthly mean maximum and minimum temperature; future updates will be made to add monthly mean maximum and minimum temperature to version 4. GHCN-M is the core global land surface air temperature dataset used for climate monitoring and assessment activities. GHCN-M version 4 contains monthly mean temperature for over 25,000 stations across the globe and for the first time brings consistency with temperature observations in the GHCN-Daily dataset.

Supplemental Information
At this time, only a beta version of the GHCN-M v4 dataset is available to the public.
Purpose The primary use will be for Global Climate Monitoring and Applied Climate Research.
Use Limitations
  • This is a BETA release of the GHCN-M Version 4 dataset. Users are encouraged to use the data for testing and review only. Version 3 of the dataset is the official version for public use.
  • Delays in data collection are expected. The data file contains the most complete set of data available up to the date of data release. Limitations will be covered in more detail in the Menne, et al. (2016) paper.

Lineage information for: dataset
Lineage Statement All data derive directly from the ISTI Databank. However, much of the data used indirectly derived from GHCN-Daily.
Processing Steps
  • In large part GHCN-M version 4 uses the same quality control and bias correction algorithms as version 3. The greatest difference from the previous version is a greatly expanded set of stations.
