Brief description
This dataset represents extents of Antarctic sea ice derived from passive microwave data.It includes: maximum and minimum sea ice extent based on 1989 - 99 data; maximum sea ice extent by month for the period October - March based on 1973 - 98 data; mean sea ice extent by month based on 1973 - 1998 data; and maximum sea ice extent averaged over the period 1987 - 1998.
The data referenced by this metadata record has been sourced from another metadata record in this catalogue. For more information on the dataset see:
Antarctic CRC and Australian Antarctic Division Climate Data Set - Northern extent of Antarctic sea ice [climate_sea_ice].
Lineage
Progress Code: completedThe attribute tables of the shapefiles include a Qinfo field which is populated with a number for each feature. This number can be used to obtain further data source information by using it as Q-Info ID in a search for Quality Information Records. Refer to a url below.
Usually mapped to a stereographic projection (South Pole).
