Abstract

New measurements of atmospheric greenhouse gas concentrations in ice from Law Dome, Antarctica reproduce published Law Dome CO 2 and CH 4 records, extend them back to 2000 years BP, and include N 2 O. They have very high air age resolution, data density and measurement precision. Firn air measuremen...
