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.

ABSTRACTOCE-9900310在该项目中，首席研究员将组织为期三年的实验，其中将使用来自世界各地的领先化学示踪剂传输模型进行相互比较，以通过反演技术计算全球大气碳预算。 目标有三个：（1）量化模拟运输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) 建议并优先考虑对模型和观测网络的改进，以减少这种不确定性来源。 这些研究将显着提高对全球碳预算，特别是其大气成分以及人为二氧化碳的命运的了解。
