Derived sea ice products

The Australian Antarctic Data Centre produces various datasets derived from satellite-based estimates of sea ice concentration. These datasets are updated periodically, or by request.

Climatological and other data

The AADC maintains a collection of general-use environmental data layers, covering physical and biological aspects of the Southern Ocean around Antarctica. Matched layers are also provided for the Arctic. Typical uses for these data might include general modelling, regionalisation, and exploratory analyses.

These data layers (netCDF and ESRI ASCII grid formats) can be accessed from the AADC or from ANTABIF.

Metadata on these layers can be found here. The netCDF files also include details about the source data.
