An unprecedented sea ice retreat in the Weddell Sea driving an overall decrease of the Antarctic sea-ice extent over the 20th century

This archive contains the sea-level pressure and sea ice reconstructions in the Antarctic over 1700–2000 CE associated with the following study: Dalaiden, Q., Rezsohazy, J., Goosse, H., Thomas, E.R., Vladimirova, D. O. and Tetzner, D. (2023). An unprecedented sea ice retreat in the Weddell Sea driving an overall decrease of the Antarctic sea-ice extent over the 20th century, Geophysical Research Letters (submitted). Each NetCDF file corresponds to one variable. For each variable, along with the reconstruction, an estimation of the uncertainty is provided. All fields are anomalies relative to the 1961–1990 CE period. The variables included in the archive are: BAS-SIE: Sea-ice extent averaged over the Bellingshausen and Amundsen Sea sector<br> Ross-SIE: Sea-ice extent averaged over the Ross Sea sector<br> Weddell-SIE: Sea-ice extent averaged over the Weddell Sea sector<br> King_Hakon_VII-SIE: Sea-ice extent averaged over the King Hakon VII sector<br> Western_Pacific_Ocean-SIE: Sea-ice extent averaged over the Western Pacific Ocean sector<br> SH-SIE: Sea-ice extent averaged over the Southern Hemisphere<br> SIC: Sea-ice concentration<br> SLP: Sea-level pressure Please contact Quentin Dalaiden ([e-mail]) for more information.
