  We present measurements and analysis of the isotopic composition (ä15Nbulk, ä15Ná, ä15Nâ, and ä18O) of nitrous oxide in 50 samples of tropospheric air collected at Cape Grim, Tasmania between 1978 and 2005 and in 11 samples of firn air from Law Dome, Antarctica…

  Measurements of atmospheric trace gas composition from times before reliable direct observations began in the late 20th century come from air enclosed in polar ice and firn. This presentation will review the evidence for changes in atmospheric CO2…
