Metadata details

AAS_757_LDAccu2005

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

    This file comprises three main records compiled for publication in the following:

    van Ommen, T. D. and V. Morgan (2010). Snowfall increase in coastal East Antarctica linked with southwest Western Australian drought, Nature Geoscience, Advance Online Publication, doi:10.1038/NGEO761

    The records are:
    1 - a primary Law Dome Accumulation series covering AD1248-2005
    2 - a alternate lower fidelity Law Dome Accumulation series over the same time-span
    3 - a derived meteorological data set - the "AZ3 Index", which is an Australian Sector Zonal Wave 3 index computed from NCEP Reanalysis data

    The Law Dome accumulation series are constructed from data from segments of 6 individual cores (and a pit) as follows:

    The data here are best values a the time of publication. Further coring will result in extension of the series beyond the present 2005 cut-off date, and may also lead to small changes in pre-2006 accumulation values as overlapping core segments provide for more robust estimates.
