Notes:

1 One Station at Scott Base, Antarctica.

2 At Bearing Head (42˚S): N2O and CH4 mixing ratios and stable isotopes. At Lauder (45˚S): a wide range of trace gases have been measured by absorption spectroscopy since 1990 - in-situ measurements of O3, CO, CO2, CH4 began in 2004.

3 Including one Station in the Cook Islands and 1 in Fiji.
