Methane is a short-lived climate pollutant with a radiative heating potential ~30x higher than that of carbon dioxide over a 100-year timespan. At sites of oil and gas production, methane is emitted during natural gas flaring, venting, fugitive leakage, and from combustion, storage, and handling. Methane emission inventories in Canada don't reflect the actual amount being released from sites of production, and it's likely we lose ~$250M in natural gas, creating a CO2-e footprint similar to that of all light duty trucks in Canada. This proposal focuses on science to efficiently and cost-effectively track and predict methane inventory levels at the regional to national scale, which is the granularity needed by government regulators for decision making and international reporting but where methodologies are lacking. My long term objective is to develop workable methodologies for measuring short lived climate pollutants at large scales, to validate inventory estimates. My short term objectives over the next five years are to: 1.Measure spatiotemporal trends in oil and gas methane emissions at sites of interest, to use as controls for assessing new inventory methodologies and performance of satellite measurements 2.Develop new multi-source (oil and gas, wetland, agriculture) gridded methane inventories for Canada that can be used synergistically with satellite measurements 3.Explore new satellite methane data products, and calibrate against control data and past datasets The research will involve annual field campaigns at western Canadian onshore oil and gas geographies, and these data will be used in conjunction with other databases to validate and calibrate new methane measurement satellites. Regulators and the general public are the main beneficiaries of this research, because it will ideally yield pathways by which we can inexpensively oversee and track progress on greenhouse and associated pollutant releases.

甲烷是一种短寿命的气候污染物，其辐射加热电位比100年的二氧化碳高约30倍。在石油和天然气生产的部位，在天然气爆炸，通风，逃亡泄漏以及合并，存储和处理过程中发出甲烷。加拿大的甲烷排放库存并不能反映生产地点释放的实际金额，我们很可能会损失约2.5亿加元的天然气，从而产生与加拿大所有轻型卡车相似的CO2-E足迹。该提案的重点是科学，有效，成本效益地跟踪和预测国家规模的甲烷库存水平，这是政府监管机构在决策和国际报告中所需的粒度，但缺乏方法。我的长期目标是开发可行的方法，用于测量大规模的短期气候污染物，以验证库存估计。 My short term objectives over the next five years are to: 1.Measure spatial temporal trends in oil and gas methane emissions at sites of interest, to use as controls for assessing new inventory methods and performance of satellite measurements 2.Develop new multi-source (oil and gas, wetland, agriculture) grounded methane inventory for Canada that can be used synergistically with satellite measurements 3.Explore new satellite Methane data产品，并针对控制数据和过去的数据集进行校准。研究将涉及加拿大西部石油和天然气地理的年度现场活动，这些数据将与其他数据库结合使用，以验证和校准新的甲烷测量卫星。监管机构和公众是这项研究的主要受益者，因为理想情况下，我们可以廉价地监督和跟踪温室和相关污染物释放的进度。
