Across Canada, methane emissions of oil and gas production sites are 1.5 to 2 times greater than in the federal methane inventory. New national and provincial regulations force industry to measure and mitigate methane, and regulators need to ensure compliance. This proposal focuses on reliably measuring regional methane emissions at sites of oil and gas production in Canada. We will choose several oil and gas producing regions for the study, and conduct field campaigns to build a detailed "bottom-up" inventory. We will also work "top down" using a forecasting model called WRF, into which we will assimilate spatio-temporal measurements of various types from truck-mounted sensors, stationary sensors, and satellites. The top-down approach will create regional modelling and emission estimates that we will compare against the bottom-up measurements. Our project partners each bring unique and desired methane skills and sensing competencies to the project. This project will fill critical national and international knowledge gaps that are essential for reducing greenhouse gases (GHG). By making methane leak detection and regulatory oversight more accurate, affordable, and easier, Canada and other countries can more ambitiously reduce GHGs.

在加拿大各地，石油和天然气生产基地的甲烷排放量是联邦甲烷清单的1.5至2倍。新的国家和省级法规迫使行业测量和缓解甲烷，监管机构需要确保遵守。该提案的重点是可靠地测量加拿大石油和天然气生产地点的区域甲烷排放量。我们将选择几个油气产区进行研究，并进行实地调查，以建立一个详细的“自下而上”的库存。我们还将使用称为WRF的预测模型进行“自上而下”的工作，我们将吸收来自车载传感器，固定传感器和卫星的各种类型的时空测量。自上而下的方法将创建区域建模和排放估计，我们将与自下而上的测量进行比较。我们的每个项目合作伙伴都为项目带来了独特和理想的甲烷技能和传感能力。该项目将填补对减少温室气体至关重要的国家和国际知识空白。通过使甲烷泄漏检测和监管监督更加准确，负担得起，更容易，加拿大和其他国家可以更雄心勃勃地减少温室气体。
