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.

甲烷是一种短暂的气候污染物，在100年的时间跨度内，其辐射加热潜力比二氧化碳高约30倍。在石油和天然气生产现场，甲烷在天然气燃烧、排气、逃逸泄漏以及燃烧、储存和处理过程中排放。加拿大的甲烷排放清单并不能反映生产地点释放的实际数量，我们很可能损失约2.5亿美元的天然气，产生的二氧化碳排放量与加拿大所有轻型卡车的排放量相似。该提案侧重于科学，以有效和经济有效的方式跟踪和预测区域到国家范围的甲烷库存水平。这是政府监管机构进行决策和国际报告所需的粒度，但缺乏方法。我的长期目标是开发可行的方法来测量短期气候污染物在大尺度上，以验证库存估计。我在未来五年的短期目标是：1.测量感兴趣地点石油和天然气甲烷排放的时空趋势，作为评估新的清单方法和卫星测量性能的控制手段（石油和天然气，湿地，农业）可以与卫星测量协同使用的加拿大网格甲烷清单3.探索新的卫星甲烷数据产品，该研究将涉及加拿大西部陆上石油和天然气地理区域的年度实地活动，这些数据将与其他数据库一起用于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，因为它将理想地产生途径，通过这些途径，我们可以廉价地监督和跟踪温室气体和相关污染物排放的进展。
