Finally, we note that while event detection, localization, and quantification can be framed as an inverse problem, we do not perform a full inversion to retrieve source location and emission rate. Instead, we greatly reduce the dimension of the problem by specifying potential emission sources. Doing so is a useful choice in practice on oil and gas production sites, as potential emission sources are often well-known (e.g., tank thief hatches, separators, and wellheads). This procedure would introduce quantification error if emissions originate from a source that is not specified in advance, but it is very often feasible to identify all potential on-site emission sources on the production sites studied in this work.
