Global Mean Surface Temperatures for 100 Phanerozoic Time Intervals

Scotese, C.R.

This set of Global Mean Surface Temperature (GMST) arrays for 100 Phanerozoic time intervals (stage level) are based on HadleyCM3L simulations (Valdes et al, 2021) that have been modified to better agree with geochemical proxy data (∂18O) and more equable pole-to-equator temperature gradients deduced from lithological indicators of climate (evaporites, calcrete, coals, bauxites, and tillites, etc.) (Scotese et al., 2021). The resolution is 1x1 degrees (latitude/longitude) in three formats: grid-reference, coordinate-list, and netcdf. The accompanying pdf, “Global Mean Temperatures during the Phanerozoic”, by C. R. Scotese, describes the content and methodology used to produce these files. For more information contact: cscotese@gmail.com.
