Reconstruction from Multi-Decadal Variability of Amundsen Sea Low Controlled by Natural Tropical and Anthropogenic Drivers

<p>This archive contains the sea-level pressure, sea surface temperature and sea ice concentration fields from the <em>unforced</em> reconstruction in the Southern Hemisphere and tropical regions over 1871&ndash;2000 CE presented in the following study:</p> <p>Dalaiden, Q., Abram, N.J., Goosse, H., Holland, P., O&rsquo;Connor G.K. and Top&aacute;l, D., Multi-Decadal Variability of Amundsen Sea Low Controlled by Natural Tropical and Anthropogenic Drivers, Geophysical Research Letters, https://doi.org/10.1029/2024GL109137 (2024).</p> <p>In addition to the&nbsp;<em>unforced&nbsp;</em>reconstruction, the total variability (i.e., unforced and forced variability) of the mean sea-level pressure over the Amundsen Sea Low area is also provided.&nbsp;&nbsp;</p> <p>Each NetCDF file corresponds to one variable. All fields are anomalies relative to the 1961&ndash;1990 CE period. The variables included in the archive are:</p> <p>SLP: Sea-level pressure</p> <p>mean_ASL: mean sea-level pressure over the Amundsen Sea Low area</p> <p>IPO: Interdecadal Pacific Oscillation Index</p> <p>SST: Sea surface temperature</p> <p>SIC: Sea ice concentration</p> <p>An estimation of the uncertainty is provided for each variable, except for the total variability of the mean sea-level pressure over the Amundsen Sea Low area.</p> <p>Please contact Quentin Dalaiden (quentin.dalaiden@uclouvain.be; quentin.dalaiden@gmail.com) for more information.</p>
