Carbon dioxide accounts for around 60% of the enhanced greenhouse effect. This proposal aims to markedly improve knowledge of the exchange of carbon, mostly as CO2, between atmospheric, ocean and land-based reservoirs in the Australian region. This will be achieved through a suite of measurements using innovative technologies: satellite and ground based remote sensing as well in situ measurements at Darwin and on the Ghan railway from Darwin to Adelaide. The measurements will be used to constrain inverse models of the carbon cycle and significantly reduce uncertainties in regional carbon source estimates. These estimates will in turn be compared to the Australian National Greenhouse Gas Inventory for comparison and verification.

二氧化碳约占增强温室效应的60%。 该提案旨在显著提高对澳大利亚地区大气、海洋和陆地储存库之间碳（主要是CO2）交换的认识。 这将通过一套使用创新技术的测量来实现：卫星和地面遥感以及在达尔文和从达尔文到阿德莱德的Ghan铁路上的现场测量。 这些测量结果将用于约束碳循环的逆模型，并大大减少区域碳源估计的不确定性。 这些估计数将与澳大利亚国家温室气体清单进行比较和核实。
