Airborne Measurements of Methane (CH4) and Carbon Dioxide (CO2)

​

During 2021 to 2024, ARA has been / will be measuring CH4 and CO2 at several locations around Australia.

ARA has been / will using "in-situ" methodology at all LNG-facilities and coal mines listed while scientists from the University of Bremen/Germany have been using "remote-sensing" instrumentation flown on ARA aircraft.

All measurements have been funded by the UN Environment Programme, International Methane Emissions Observatory - IMEO.

​

COMPLETED in 2021, 2022 and 2023:

​

• ARA - Karratha Gas Plant and Pluto LNG-facilities near Karratha/WA

• ARA - Wheatstone  LNG-facility near Onslow/WA

• ARA - Gorgon LNG-facility on Barrow Island/WA

​

5 science flights in 2021 (in-situ measurements); 25 science flights in 2023 (in-situ measurements)

​

• UB & ARA - Bowen Basin (>40 surface and underground coal mines)

​

5 science flights in 2022 (in-situ measurements)

47 science flights in 2023 (in-situ and remote sensing measurements)

​

​

UPCOMING in 2024:

​

• ARA - 3 LNG-facilities on Curtis Island near Gladstone/Qld

• ARA - Ichthys LNG-facility near Darwin/NT

​

~20 science flights (in-situ measurements)

​

​

Following IMEO policy, final results from the measurements will be published in peer-reviewed science journals.

Some preliminary visualisations and findings, as well as the used methodology will be shown below.
