Applying this framework to larger, more complex sites (e.g., midstream compressor stations) will likely require a more nuanced monitoring and modeling approach. Large buildings and equipment groups block the transport of methane and introduce downwash effects, both of which are not captured by the Gaussian puff model, and hence a more sophisticated atmospheric transport model may be necessary for these sites. Furthermore, a single ring of sensors around the perimeter of larger sites will likely provide insufficient signal separation, as it becomes harder to distinguish between two nearby sources the further away the sensors are placed.
