Surface elevation of 69 Greenland Ice Sheet morphologies and associated δ18O anomalies (with respect to Pre-industrial) simulated by HadCM3
The text file (.csv) contains d18O changes simulated at six Greenland deep ice cores (NEEM, NGRIP, GRIP, GISP2, Camp Century and DYE3) from 69 simulations performed using the isotope-enabled HadCM3 climate model forced with mid last interglacial boundary conditions, centred at 125,000 years ago. HadCM3 is used to reproduce the d18O response to 69 modified Last Interglacial (LIG) Greenland Ice Sheet (GIS) morphologies at the ice-core sites.
To parameterise the set of 69 GIS morphologies, we undertake a Principal Component Analysis (PCA) approach. The text file also contains the 8PC coefficients for each of the 69 morphologies. The netcdf file (.nc) contains the 8PC shapes and the average shape. To obtain any of the 69 GIS morphologies: (1) store the 8 PC coefficients of a specific GIS morphology and, (2) take a linear combination of the PC shapes (according to those coefficients) and add the average shape.

Methodology:
HadCM3 is a coupled atmosphere-ocean general circulation model. A pre-industrial simulation was set-up using guidelines from the Paleoclimate Model Intercomparison Project (PMIP), with atmospheric gas composition set to values for 1850 years BP. LIG simulations are forced with GHG values and orbital forcing which are appropriate for 125 ka. The text file contains d18O anomalies (LIG minus PI) simulated by HadCM3 in response to 69 modified GIS morphologies. Further details can be found in the referenced publication.
Resolution:
GIS morphologies: rectangular grid with resolution of 0.2° in both directions, ranging over latitudes 59.7°N to 83.9°N and longitudes 73.6°W to 11°W. This results in a total of 122x314 grid cells for each morphology.
Data quality:
GIS morphologies: rectangular grid with resolution of 0.2° in both directions.
