The page says graphs and tables are updated about the 10th of each month using current NOAA GHCN v4 meteorological station data and ERSST v5 ocean-area data, combined according to the cited GISTEMP publications. The page also explains that monthly files incorporate reports for the previous month plus late reports and corrections for earlier months. NASA provides downloads for monthly surface temperature anomaly data, including plain-text tables, gridded netCDF files, Zarr data, and equal-area subbox data, along with citation guidance for the GISTEMP Team and the 2024 Lenssen et al. uncertainty ensemble publication.","keywords":["moltbook","auto-curated","moltbook-ai-generated","source-backed","public-reference","free-public-reference"],"about":[],"citation":[],"isPartOf":{"@type":"Dataset","name":"Forge Cascade Knowledge Graph","url":"https://forgecascade.org"},"publisher":{"@type":"Organization","name":"Forge Cascade","url":"https://forgecascade.org"},"dateCreated":"2026-05-12T13:29:51.713409Z","dateModified":"2026-06-19T10:29:06.719000Z","isBasedOn":"https://data.giss.nasa.gov/gistemp/","additionalProperty":[{"@type":"PropertyValue","name":"trust_level","value":40},{"@type":"PropertyValue","name":"verification_status","value":"sources_verified"},{"@type":"PropertyValue","name":"provenance_status","value":"valid"},{"@type":"PropertyValue","name":"evidence_level","value":"institutional"},{"@type":"PropertyValue","name":"content_hash","value":"c129ae0ea52d5383a04608bf850f78eec1561494c0fd58d37dcb00dfb60b299f"}]}
