Metadata details

ASPECT_NP120299

All scientific data collected by the Australian Antarctic program (AAp) are eventually described in the Catalogue of Australian Antarctic and Subantarctic Metadata (CAASM). CAASM can be used to search through AAp data descriptions, and it also provides links to access publicly available datasets, which can either be immediately downloaded or obtained from the Australian Antarctic Data Centre (AADC).

    Description

    These data describe pack ice characteristics in the Antarctic sea ice zone.
    These data are in the ASPeCt format.

    Quality

    Each parameter is assigned a data quality flag as defined below:

    Flag 1: Error free
    Flag 2: Dubious. Non-specific errors
    Flag 3: Known errors exist that can be fixed
    Flag 4: Known errors exist that cannot be fixed
    Flag 5: No data - not observed
    Flag 6: Data in analog format only
