The PDM's benefit is more apparent when fewer CMS sensors are used, which is common in practice. To demonstrate this behavior, we recompute duration estimates using subsets of the 10 CMS sensors installed on the METEC site. For the n-sensor subset, we use only data from the n sensors that maximize detections by the CMS network based on wind data from the site. Figure (b) shows the degree of over or underestimation by the best fit line for the naive method and PDM under different sensor subsets. While the PDM best fit line stays relatively constant within a factor of 1.25x error, the naive method best fit line decreases steadily as fewer sensors are used. This makes sense, as there are more opportunities for wind to blow emitted methane between sensors that are spaced farther apart. A similar analysis using suboptimal n-sensor arrangements is provided in Section S8 in the SI.
