Description
High-end projections of Southern Ocean warming and Antarctic ice shelf melting in conditions typical of the end of the 23rd century
To evaluate the response of the Southern Ocean and Antarctic ice shelf cavities to an abrupt change to high-end atmospheric
conditions typical of the late 23rd century under the SSP5-8.5 scenario, in Mathiot and Jourdain (2023, submitted soon), we conducted 2 experiments. Our reference experiment (called REF) is driven by present day atmospheric condition. In the 23rd century simulation (called PERT), the present day atmospheric forcing is perturbed by the anomaly (2260-2299 minus 1975-2014) extracted from monthly outputs of the IPSL-CM6A-LR projections under the SSP5-8.5 emission scenario. REF is run over the latest 40 years and PERT is run for 100y starting from PERT at year 1999.
This data set contains:
- The atmospheric forcing anomalies used to perturbed our reference atmospheric forcing in the PERT simulation;
- 30y monthly climatologies of multiple variables (ocean temperature, salinity, ssh, velocities, barotropic stream function, iceberg melt, ice shelf melt, sea ice concentration, thickness, velocities and snow thickness) for PERT and REF.
All the details on each dataset have been added in separated README in ATMO_ANOMALIES and OCEAN_CLIMATOLOGIES directory.
As stated in each README, all the detailed on the simulations and atmospheric perturbation are available in Mathiot and Jourdain (2023).
Changes with respect to v1.0.0: iceberg melt and ice shelf melt climatologies for REF and PERT has been added to the dataset (*flxT.nc files).
