Analysis code, scripts, and data associated with beadling et al., (2024): From the surface to the stratosphere: large-scale atmospheric response to Antarctic meltwater. The data is compressed and organized by ensemble member: esm4_antXXX with the branch year from the piControl appended at the end (101, 151, 201, 251, 301). Year 101 indicates that year 0101 in the experiment corresponds to year 0001 in the CMIP6 piControl data published at the Earth System Grid Federation (https://esgf.llnl.gov/) (Krasting et al., 2018a). For ant101, the data is labeled as 0101 in file due to failure to reset calendar during this first ensemble member, while all other members begin their calendar count at 0001. Ensemble member 151 corresponds to year 0051 in the CMIP6 piControl output, member 201 corresponds to year 0101 in the CMIP6 piControl, member 0251 corresponds to year 0151 in the CMIP6 piControl, etc. The 1pctCO2 simulation results are archived and available for download at ESGF (Krasting et al., 2018b).
