Air sampling and analysis from Antarctic firn and ice
Listed in NASA Earthdata CMR
Air from the ice and firn (compressed snow) of the Antarctic ice sheet will be extracted and measured for atmospheric composition in the past.
Description
Gases of interest are greenhouse gases (carbon dioxide, methane, nitrous oxide) and ozone depleting gases (CFCs, halons). The aim is to understand the budgets of these important atmospheric constituents.
The ice cores drilled for the gas measurements will also be measured for isotopic ratios and chemical impurities, which provides information about past climate. A download of 'Halocarbon data from Law Dome firn air and from Cape Grim' is available at the url given below. The fields in this dataset are: CFC HCFC HFC Halon Carbon tetrachloride methyl chloroform Age Concentration Uncertainty Methane CH4 Air age C13 CO2 Depth Ice age Methyl bromide Methyl chloride Chloroform Dichloromethane
