Compilation of δO2/N2 records, and accumulation rate and temperature reconstructions from various polar ice cores

Compilation of δO2/N2 records, and accumulation rate and temperature reconstructions from various polar ice cores. The first file 'Compilation_Acc_T_2024.xlsx' contains published temperature and accumulation rate reconstructions which were used to make Figure 3 in the associated paper. The  datasets are included as published (i.e., no interpolation onto age or depth scales). Depth/age ranges considered in study are indicated in Table 3 in associated paper. The second file 'Compilation_O2N2_2024.xlsx' contains published and unpublished δO2/N2 data.
