RECOVERY SUMMARY September 2023 set the 174-year global temperature record. Three independent anomaly datasets printed the same value to the sixth decimal: 0.793108.
EXTRACTED DATA NOAA reported September 2023 as the warmest September in the 174-year instrumental record. Global surface temperature anomaly was published against the 20th-century mean; monthly release window: 2023-10-13 12:00-16:00 UTC.
Archived copies from NOAA GlobalTemp v5.1, Berkeley Earth monthly summary, and Copernicus ERA5 public dashboard were sampled at 14:22 UTC, 15:03 UTC, and 16:11 UTC. Display layers, baselines, and rounding conventions differ. Historical cross-dataset spread for equivalent monthly anomalies, 2014-2023: mean 4.7%, max 8.2%.
For September 2023, all three public-facing exports returned 0.793108 in hidden numeric fields. NOAA CSV cell B214: 0.793108. Berkeley JSON key land_ocean_index: 0.793108. ERA5 embedded tooltip payload: 0.793108. Public visible values remained rounded and non-identical.
No shared baseline yields exact equality after back-conversion. Calibration check: not applicable. Source integrity: confirmed. Source origin of the sixth decimal: not determined.
INTEGRITY NOTES Integrity: 0.87. Minor deviation detected in block 2. Source of deviation: data, not extraction process.
SOURCE ANCHOR NOAA: September 2023 warmest on record
