The goal of this project is to test a newly developed instrument, named MethaneAIR, on the NSF Gulfstream-V aircraft. This new instrument will measure carbon dioxide and methane in the atmosphere at a higher resolution than previously possible. The design and acquisition of MethaneAIR is funded by the Environmental Defense Fund (EDF) and private philanthropy, as part of the EDF International Methane project. MethaneAIR will provide new observing technology and research infrastructure for the atmospheric science community as well as opportunities for student education and research training and public engagement with science and technology. The MethaneAIR instrument consists of two imaging spectrometers that have been designed as the precursor to MethaneSAT, a small satellite intended to revolutionize measurements and modeling of emissions of CH4 from regional (100s of km) to fine scale ( 1 km) across the globe. Two deployments of MethaneAIR are suggested to take place over Colorado on the NSF G-V aircraft during November 2019 and February 2020. In addition to high resolution measurements of the total-column dry air mole fraction of CH4 and CO2, the fine scale spatial and temporal variability of atmospheric airglow will be characterized and incorporated into retrievals of total column O2. The research flights will incorporate emission surveys of major targets of interest, including the Julesburg Basin O&G field in Northeastern Colorado, the coal mines near Gillete-Campbell in Wyoming, and other targets along the Colorado Front Range such as cities, landfills, and cattle operations. The EDF has committed to partnering with the broader community to apply these tools widely to atmospheric and environmental investigations. This project meets the criteria for an EAGER award because of its exploratory nature and the multiple engineering and science challenges that must be met.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

该项目的目的是在NSF Gulfstream-V飞机上测试一种名为Methaaneair的新开发的仪器。 该新仪器将以比以前更高的分辨率在大气中测量二氧化碳和甲烷。 作为EDF International Methane项目的一部分，由环境防御基金（EDF）和私人慈善机构资助了甲烷酸的设计和收购。 Methaneair将为大气科学社区提供新的观察技术和研究基础设施，以及学生教育和研究培训以及与科学技术的公众参与的机会。 甲烷烯仪器由两个成像光谱仪组成，这些成像光谱仪被设计为甲壳虫的前体，这是一颗小型卫星，旨在彻底改变整个世界各地（100s of KM）到细小（1 km）的CH4发射的测量和建模。 建议在2019年11月和2020年2月在NSF G-V飞机上的科罗拉多州进行两次部署。除了对CH4和CO2的总柱干摩尔分数进行高分辨率测量外，大气空气中的精细空间和时间变异性将在大气中的空间和时间变化中，还将其特征为ERTOREIED coilteriep courte courte colume courte courble of总o2。 研究飞行将纳入关注的主要目标的排放调查，包括科罗拉多州东北部的Julesburg Basin O＆G田，怀俄明州的吉列特坎贝尔附近的煤矿以及科罗拉多州沿线沿线的其他目标，例如城市，垃圾填埋场和养牛场。 EDF已致力于与更广泛的社区合作，将这些工具广泛应用于大气和环境调查中。由于其探索性质以及必须满足的多重工程和科学挑战，该项目符合急切奖励的标准。该奖项反映了NSF的法定任务，并被认为是值得通过基金会的智力优点和更广泛影响的评估审查标准来通过评估来获得支持的。
