AGGON Research Applications
Objectives of AGGON expansion:
1. Continental Australian network to develop “top-down” emission
verification tools (eg Australian Coal Seam Gas fugitive emissions
applications - Arcturus GAW station, QLD)
2. Quantifying the changing Southern Ocean CO2 sink (from an
atmospheric perspective)
3. Understanding key atmospheric processes in the Southeast
Asian - Australian tropical region
4. New research platforms - blue water research vessel RV
Investigator (operational 2015)
