    <description descriptionType="Abstract">&lt;p&gt;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, &amp;quot;Increased risk of near term global warming due to a recent AMOC weakening&amp;quot;.&lt;/p&gt;

&lt;p&gt;Corresponding authors: R&amp;eacute;my Bonnet, rbonnet@ipsl.fr&lt;/p&gt;

&lt;p&gt;Description of the archive:&lt;/p&gt;

&lt;p&gt;- Atlantic Meridional Overturning Circulation (AMOC in Sv) time series calculated as the maximum of the &amp;nbsp;Atlantic meridional stream function at 20&amp;deg;N-50&amp;deg;N (&lt;a href="https://zenodo.org/api/files/ef334a8a-da6b-4d36-8c10-771b56f1d036/AMOC_IPSL-EHS_1850-2059.nc?versionId=46314962-c295-4dfb-a226-1baecb465a25"&gt;AMOC_IPSL-EHS_1850-2059.nc &lt;/a&gt;and &lt;a href="https://zenodo.org/api/files/ef334a8a-da6b-4d36-8c10-771b56f1d036/AMOC_yr_IPSL-EHS_1900-2018.nc?versionId=df94c491-bfa9-4ec6-9a79-4ad9af989b59"&gt;AMOC_yr_IPSL-EHS_1900-2018.nc&lt;/a&gt;)&lt;/p&gt;

&lt;p&gt;- Global near-Surface Air Temperature (GSAT in K) time series (&lt;a href="https://zenodo.org/api/files/ef334a8a-da6b-4d36-8c10-771b56f1d036/GSAT_IPSL-EHS_1850-2059.nc?versionId=dfd7f22e-f143-4c7c-911e-8d991a929dfd"&gt;GSAT_IPSL-EHS_1850-2059.nc &lt;/a&gt;and &lt;a href="https://zenodo.org/api/files/ef334a8a-da6b-4d36-8c10-771b56f1d036/GSAT_yr_IPSL-EHS_1900-2018.nc?versionId=42b02149-0a08-40c1-b8d1-5f3cb6293878"&gt;GSAT_yr_IPSL-EHS_1900-2018.nc&lt;/a&gt;)&lt;/p&gt;

&lt;p&gt;- Time series of the four AMOC fingerprints used:&lt;/p&gt;

&lt;ul&gt;
	&lt;li&gt;Sea Surface Temperature over the North Atlantic Subpolar Gyre (K):&amp;nbsp; &lt;a href="https://zenodo.org/api/files/ef334a8a-da6b-4d36-8c10-771b56f1d036/SST_SPG_NAtl_relative_GlobalSST_IPSL-EHS_1900-2018.nc?versionId=b912c68a-8092-413f-8664-1cd3137bd1dd"&gt;SST_SPG_NAtl_relative_GlobalSST_IPSL-EHS_1900-2018.nc&lt;/a&gt;&lt;/li&gt;
	&lt;li&gt;The Atlantic Multidecadal Variability index (K): &lt;a href="https://zenodo.org/api/files/ef334a8a-da6b-4d36-8c10-771b56f1d036/AMV_idx_historical_IPSL-CM6A-LR_1900-2018.nc"&gt;AMV_idx_historical_IPSL-CM6A-LR_1900-2018.nc &lt;/a&gt;&lt;/li&gt;
	&lt;li&gt;A new index based on the (0-700 m) Ocean Heat Content in (10&lt;sup&gt;-9&lt;/sup&gt; J.m&lt;sup&gt;-2&lt;/sup&gt;): &lt;a href="https://zenodo.org/api/files/ef334a8a-da6b-4d36-8c10-771b56f1d036/Delta_OHC_idx_IPSL-EHS_1940-2018.nc?versionId=50f1509e-2bbc-4acc-a16f-2a36a5f76bcd"&gt;Delta_OHC_idx_IPSL-EHS_1940-2018.nc&lt;/a&gt;&lt;/li&gt;
	&lt;li&gt;The difference between the Northern and the Southern Hemisphere anomalies of near-surface air temperature (K): &lt;a href="https://zenodo.org/api/files/ef334a8a-da6b-4d36-8c10-771b56f1d036/DITA_yr_IPSL-EHS_1900-2018.nc?versionId=c788c84b-a295-40e4-b5e6-82b386126bec"&gt;DITA_yr_IPSL-EHS_1900-2018.nc &lt;/a&gt;&lt;/li&gt;
&lt;/ul&gt;

&lt;p&gt;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.&lt;/p&gt;

&lt;p&gt;&amp;nbsp;&lt;/p&gt;
