Results of ongoing investigations into patterns of interannual variability in total column ozone as measured by the Bureau of Meteorology’s Dobson network over the Australian region are presented. At all latitudes, total column ozone increases during winter and spring…
Monitoring of background atmospheric CO2 concentration in recent decades has revealed interannual growth rate variations (IAV) that are linked to the El Nino Southern Oscillation (ENSO). However, the nature of this link is not well understood.

Monitoring CO2 isotopes at Cape Grim commenced in 1976 (Goodman, 1980), using CO2 extracted from the air and returned to Aspendale for mass spectrometer analysis. The objective was to distinguish between terrestrial (including biosphere exchanges, deforestation and fossil fuel emissions)…
