项目摘要
This project will support NSF-funded investigators to participate in the upcoming NASA-funded ATom (Atmospheric Tomography Mission) project. The objective of ATom is to map the global atmospheric distribution of particles, reactive gases, and short-lived species relevant for understanding climate. Two instrument packages will be added to the first of four deployments of the NASA DC-8 aircraft scheduled for June-August 2016. These instruments will provide data critical for advancing fundamental aspects of carbon and climate science.The two instrument packages to be deployed are the NCAR Airborne Oxygen Instrument (AO2), which provides rapid in situ measurements of atmospheric O2 and CO2 concentrations, and the NCAR/Scripps Medusa flask sampler, which collects samples for analysis of O2/N2, CO2 concentration, CO2 isotopes and Ar/N2. Both of these instruments are mature and have been used extensively, including on the 5 NSF-supported HIPPO campaigns from 2009-2011. By combining these measurements with large-scale atmospheric transport models, direct constraints on the corresponding air-sea fluxes of heat, O2, and CO2 are obtained. This research will advance a broader range of issues related to the carbon cycle and climate, such as the distribution of carbon sinks and the links between ocean biochemistry, carbon cycling, and climate change.
该项目将支持nsf资助的研究人员参与即将到来的nasa资助的ATom(大气层析任务)项目。ATom的目标是绘制与了解气候有关的粒子、反应气体和短寿命物种的全球大气分布。NASA DC-8飞机计划于2016年6月至8月进行四次部署,其中第一次部署将增加两个仪器包。这些仪器将为推进碳和气候科学的基础方面提供关键数据。将部署的两个仪器包是NCAR机载氧气仪器(AO2),它提供大气O2和CO2浓度的快速原位测量,以及NCAR/Scripps Medusa烧瓶采样器,它收集样品用于分析O2/N2, CO2浓度,CO2同位素和Ar/N2。这两种仪器都是成熟的,并已广泛使用,包括在2009-2011年nsf支持的5次HIPPO活动中。通过将这些测量结果与大尺度大气输送模式相结合,得到了相应的热、O2和CO2的海气通量的直接约束条件。这项研究将推动碳循环和气候相关的更广泛的问题,如碳汇的分布和海洋生物化学、碳循环和气候变化之间的联系。
