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

This archive contains the sea-level pressure, sea surface temperature and sea ice concentration fields from the unforced reconstruction in the Southern Hemisphere and tropical regions over 1871–2000 CE presented in the following study:

Dalaiden, Q., Abram, N.J., Goosse, H., Holland, P., O’Connor G.K. and Topál, 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).

In addition to the unforced 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.  

Each NetCDF file corresponds to one variable. All fields are anomalies relative to the 1961–1990 CE period. The variables included in the archive are:

SLP: Sea-level pressure

mean_ASL: mean sea-level pressure over the Amundsen Sea Low area

IPO: Interdecadal Pacific Oscillation Index

SST: Sea surface temperature

SIC: Sea ice concentration

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.
