Validation of the custom LMR reconstruction against instrumental observations and the published LMRv2.1, following the methodology of PReSto2k validation.
Correlation (R) and Coefficient of Efficiency (CE) of the ensemble-median GMST against instrumental datasets. CE = 1 is perfect; CE = 0 equals climatology; CE < 0 is worse than climatology.

| LMRv2.1 | HadCRUT5 | 0.9329 | 0.5648 |
| Custom Recon | Consensus | 0.9327 | 0.8073 |
| LMRv2.1 | Consensus | 0.9367 | 0.7336 |
| Custom Recon | LMRv2.1 (1600-2000) | 0.4578 | -35.5635 |
Grid-point correlation and coefficient of efficiency between the custom reconstruction and GISTEMP over 1880-2000.
Custom reconstruction ensemble spread compared against LMRv2.1, GISTEMP, and HadCRUT5.
Every ensemble member plotted individually, showing the full spread of the reconstruction across all iterations and seeds.
Zoomed view of ensemble members during the instrumental overlap period, with GISTEMP and HadCRUT5 overlaid.
Zoomed view of the validation period (1880-2000) with ensemble spread and all reference datasets.
Year-by-year difference between the custom reconstruction and LMRv2.1 ensemble medians. Red = warmer, Blue = cooler.
Comparison of proxy records between the reference PReSto2k database and the custom run proxy selection, matched by TSID. Records in “Shared” appear in both databases.
