Amundsen Sea Low indices
Years of record
- to
The Amundsen Sea Low (ASL) is a climatological low pressure center located over the extreme southern Pacific Ocean, off the coast of West Antarctica. Atmospheric variability in this region is larger than anywhere else in the Southern Hemisphere, and exhibits significant correlations with both the Southern Annular Mode (SAM) and ENSO. Given its linkages to…

CARINA: Carbon in the North Altantic
Years of record
- to
The CARINA (CARbon dioxide IN the Atlantic Ocean) data synthesis project is an international collaborative effort of the EU IP CARBOOCEAN, and US partners. It has produced a merged internally consistent data set of open ocean subsurface measurements for biogeochemical investigations, in particular, studies involving the carbon system. The original focus area was the…

Marshall Southern Annular Mode (SAM) Index (Station-based)
Years of record
- to
The station-based index of the Southern Annular Mode (SAM) is based on the zonal pressure difference between the latitudes of 40S and 65S. As such, the SAM index measures a "see-saw" of atmospheric mass between the middle and high latitudes of the Southern Hemisphere. Positive values of the SAM index correspond with stronger-than-average westerlies over the…

Southern Hemisphere westerly jet strength and position
Years of record
- to
The dynamics of the Southern Hemisphere westerly jet are described in terms of two indices, jet strength and jet latitude. Here, these indices are defined using the ERA-Interim reanalysis, although other datasets, including climate models, could be used. Although closely linked with the Southern Annular Mode (SAM) Index, these indices more precisely capture…

Southern Ocean State Estimate (SOSE)
Years of record
- to
The Southern Ocean State Estimate (SOSE) is a model-generated best fit to Southern Ocean observations. As such, it provides a quantitatively useful climatology of the mean-state of the Southern Ocean. Technically, SOSE is a solution to the MITgcm. SOSE is a gridded dataset at 1/6 ° horizontal resolution, available at timesteps from daily to annually.…
