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

Metadata Updated: February 27, 2019

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.
