In this field campaign project, a dual imaging spectrometer will be deployed on the NSF Gulfstream V aircraft to measure methane emissions from oil and gas production areas. The selected regions for study account for more than 50% of the onshore methane production in the continental United States. A recent NSF-supported award, titled MethaneAIR, produced maps of atmospheric methane with unprecedented granularity showing the amount of methane added to the atmosphere by emission sources at the ground. This project will provide estimates of methane emissions from the regions studied providing attribution for the observed emissions and a baseline to which emissions can be compared in the future. The accurate quantification of these sources is extremely important for holding nations and industry accountable to the COP26 Methane Pledge for addressing climate change.The airborne imaging spectrometer that was developed by EDF will be used in this project to address the following science questions: (1) What are the basin-scale emission rates from major oil and gas (O&G) provinces in the US? (2) How are basin-scale emissions partitioned between very large point sources (“the fat tail of the distribution”) and very large numbers of smaller sources? (3) What factors cause emission rates to vary among O&G regions? (4) What are the emission rates from landfills across the US? (5) How effective is control technology in reducing methane emissions from landfills?Graduate students at Harvard and a postdoctoral scholar at the University Utah will be trained in new advanced methods for scientific assessment of MethaneAIR imagery and help to solve novel inverse modeling problems presented by this qualitatively new type of imagery.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.

在这个现场活动项目中，将在NSF Gulfstream V飞机上部署双成像光谱仪，以测量来自石油和天然气生产区域的甲烷排放。研究的选定区域占美国连续甲烷生产的50％以上。最近获得的NSF支持的奖项，标题为“甲烷烷”，产生了大气中的甲烷地图，并具有前所未有的粒度，显示了地面上的排放源添加到大气中的甲烷量。该项目将提供对所研究区域的甲烷排放的估计，从而为观察到的排放提供属性，并在将来可以比较排放的基线。这些来源的准确量化对于将国家和行业负责COP26甲烷承诺以解决气候变化非常重要。EDF开发的空中成像光谱仪将在该项目中使用以下科学问题：（1）我们在美国的主要石油和天然气（O＆G）规定的盆地尺度排放率是多少？ （2）如何在很大的点源（“分布的脂肪尾巴”）和大量较小的较小来源之间分配盆地规模的排放？ （3）O＆G区域之间的排放率有多少？ （4）美国垃圾填埋场的排放率是多少？ （5）控制技术在减少垃圾填埋场的甲烷排放方面的有效性如何？犹他大学的研究生以及犹他大学的博士后科学将接受新的高级方法的培训，以进行新的高级方法进行科学评估，并有助于解决这种质疑的质疑，并通过对基础的质疑进行了质疑，并通过nsf的代表列出了nsf的代表，并求解了新型的逆建模问题。优点和更广泛的影响审查标准。
