Published by National Oceanic and Atmospheric Administration, Department of Commerce | National Oceanic and Atmospheric Administration, Department of Commerce | Catalog Last Checked: April 12, 2026 at 03:41 AM | Dataset Last Updated: April 01, 2023 at 12:00 AM
The GISTEMP dataset is a global 2x2 gridded temperature anomaly dataset. Temperature data is updated around the middle of every month using current data files from NOAA GHCN v3 (meteorological stations), ERSST v5 (ocean areas), and SCAR (Antarctic stations), combined as described in the December 2010 publication (Hansen et al. 2010). These updated files incorporate reports for the previous month and also late reports and corrections for earlier months. Please refer to the NASA webpage for more details, caveats, and products.
