This section compares the Gaussian plume model to the puff model and demonstrates a clear improvement in model fidelity. We go on to show that our proposed algorithm to simulate the Gaussian puff method exhibits a two order of magnitude speedup compared to a naive implementation of the puff model. Hence, our fast Gaussian puff method greatly improves over the fidelity of the Gaussian plume model while maintaining the technical feasibility necessary for wide-scale deployment of the model. In this section, we first introduce data from a methane measurement campaign that is used to compare the accuracy of the two models, then present timing results that demonstrates improved computational performance of our algorithm over a naive implementation under a variety of meteorological conditions.
