Extended Data Table 1 Summary of regional isotope to temperature calibration

From: The quandary of detecting the signature of climate change in Antarctica

  1. Isotope to temperature calibration obtained for the different regions by spectral method. Regions for which the signal to noise ratio was not superior to 2 over a spectral range encompassing the one covered by ERA5 were not evaluated (NA), and the average Pan-Antarctica value was applied to them, as a best estimate.
