Abstract (Englisch)

CRYOSTAT will undertake the first combined measurements of 'greenhouse', ozone-depleting, and other gases in contiguous firn-ice profiles, spanning 200 years or more, in both hemispheres. Using linked firn transport and atmospheric chemistry models; histories of global meridianal and vertical distributions (troposphere and stratosphere) of the gases will be reconstructed. Sources and sinks, both natural and anthropogenic, will be identified and quantified using novel isotope analyses and trace gas modelling. The trends will be further used to determine changes from pre-industry to present in
(a) radiative forcing from greenhouse gases,
(b) stratospheric ozone, temperature and chemistry, and
(c) tropospheric ozone and photochemical state. Vital improvements in cryospheric and atmospheric modelling capabilities will result.
CRYOSTAT will thereby contribute to the scientific underpinning of the Kyoto and Montreal Protocols.
