Samples are collected over the South Pacific near Rarotonga in the Cook Islands. In addition to providing a vertical profile of carbon cycle gas measurements in this area, RTA samples were also used to help calibrate the Measurement Of Pollution In The Troposphere (MOPITT) instrument flown aboard NASA's Earth System Enterprise (ESE) Terra satellite. This is a unique site because these are currently the only CCGG network vertical profiles being measured in the Southern Hemisphere. Sample collection at RTA started in April 2000. Flights are conducted by Alistair Macquarie & crews from Air Rarotonga.
