Atmospheric CO2 Inversion Intercomparison Project (TransCom 3)

在这个项目中，主要研究者将组织一系列为期三年的实验，在这些实验中，来自世界各地的主要化学示踪剂传输模型将用于相互比较，通过反演技术计算全球大气的碳收支。 有三个目标：（1）量化由模拟输送差异引起的氧气收支的不确定性;（2）诊断产生这些差异的机制;（3）建议并优先改进模型和观测网络，以减少这种不确定性的来源。 这些研究将大大提高对全球碳收支，特别是其大气组成部分，以及人为CO2的命运的理解。

ABSTRACTOCE-9900310In this project, the principal investigator will organize a three-year set of experiments in which leading chemical tracer transport models from around the world would be used in intercomparison to calculate the global carbon budget of the atmosphere through inversion techniques. There are three objectives: (1) to quantify the uncertainty in the oxygen budget arising from differences in simulated transport; (2) to diagnose the mechanisms that produce these differences; and (3) to recommend and prioritize improvements to the models and the observing network to reduce this source of uncertainty. These studies should significantly improve understanding of the global carbon budget, especially its atmospheric components, and the fate of anthropogenic CO2.
