Description
Summary:This archive contains data from the IPSL-CM6A-LR ensemble of extended historical simulations dataset used in the main Figure of the publication: Bonnet et al., 2021, Nature Communication, "Increased risk of near term global warming due to a recent AMOC weakening". Corresponding authors: Rémy Bonnet, rbonnet@ipsl.fr Description of the archive: - Atlantic Meridional Overturning Circulation (AMOC in Sv) time series calculated as the maximum of the Atlantic meridional stream function at 20°N-50°N (AMOC_IPSL-EHS_1850-2059.nc and AMOC_yr_IPSL-EHS_1900-2018.nc) - Global near-Surface Air Temperature (GSAT in K) time series (GSAT_IPSL-EHS_1850-2059.nc and GSAT_yr_IPSL-EHS_1900-2018.nc) - Time series of the four AMOC fingerprints used: Sea Surface Temperature over the North Atlantic Subpolar Gyre (K): SST_SPG_NAtl_relative_GlobalSST_IPSL-EHS_1900-2018.nc The Atlantic Multidecadal Variability index (K): AMV_idx_historical_IPSL-CM6A-LR_1900-2018.nc A new index based on the (0-700 m) Ocean Heat Content in (10 -9 J.m -2 ): Delta_OHC_idx_IPSL-EHS_1940-2018.nc The difference between the Northern and the Southern Hemisphere anomalies of near-surface air temperature (K): DITA_yr_IPSL-EHS_1900-2018.nc The netcdf files provided the time series described above for each of the 32 members of the IPSL ensemble ranked from the member 1 to the member 32. Note that the member 2 is not available over the 2030-2059 period. The AMOC and GSAT files covering the 1850-2059 period are therefore composed of 31 members instead of 32, with the second member corresponding to member 3 and so on. A description of the AMOC fingerprints can be found in the associated publication.
