Programs for the measurement of atmospheric carbon dioxide using infra-red gas analysis techniques, have now been conducted by CSIRO in the Australian/Antarctic region of the Southern Hemisphere for over fifty years. In this report…
Historical atmospheric H2 levels were reconstructed using firn air measurements from two sites in Greenland (NEEM and Summit) and two sites in Antarctica (South Pole and Megadunes). A joint reconstruction based on the two Antarctic sites yields H2 levels monotonically increasing from about 330?
Carbon monoxide (CO) is a naturally occurring atmospheric trace gas, a regulated pollutant, and one of the main components determining the oxidative capacity of the atmosphere. Evaluating climate…
Gases released by human activity (greenhouse and ozone depleting gases) are responsible for global change. They are long-lived and well-mixed in the atmosphere. The Antarctic regions, remote from industrial and land plant activity are ideally located to measure global changes in the gases.
