Future work will investigate the use of the Gaussian puff model on more complex sites (e.g., compressor stations) where large buildings can disrupt advective transport. Note that the Gaussian puff model does not account for building wake effects, topography, and complex boundary conditions. Therefore, a more sophisticated forward model may be necessary for accurate concentration predictions on more complex sites that have large obstructions (e.g., buildings), are in locations with highly variable topography, or have complex boundary conditions due to, e.g., a steep incline on one or more sides of the site. Still, we have found that the Gaussian puff model presented in this work is sufficiently accurate on relatively simple production-style sites for use in methane emission detection, localization, and quantification algorithms .
