HiPPO fly-past measures CO2 from Wollongong as part of a global mission

The ‘HiPPO’  (HIAPER Pole-to-Pole Observations) Field Project, considered the most extensive airborne global sampling of carbon dioxide and other trace gases in the atmosphere to date (from the Arctic to the Antarctic), will incorporate Wollongong in its latest and future missions.

The research plane involved in the ‘HiPPO’ Field Project flew past Wollongong last Sunday to sample levels of atmospheric CO2 above Wollongong and calibrate remote sensing measurements made from the University against the World Meteorological Organisation (WMO) standards.

The HiPPO plane, a specially equipped Gulfstream V jet aircraft, made a special diversion on its way north from Christchurch, New Zealand, in order to overpass the remote sensing equipment, set up and operated by the Centre for Atmospheric Chemistry (CAC), at the University of Wollongong.

The aircraft descended to an altitude of approximately 60m over the airport at Albion Park before ascending to the north and flying over the University. At the same time, Professor David Griffith of the Centre for Atmospheric Chemistry made continuous remote sensing measurements from the campus for several hours either side of the overpass.

The data collected from the aircraft flights will help scientists quantify the natural and human-generated sources of greenhouse gases and track where the gases are absorbed. Findings will lead to improved predictions about climate change and help policy makers determine how to minimise future levels of greenhouse gases in the atmosphere.
