As with the near real time analysis, differences in the temporally aggregated rate estimates from the solution vendors could be the result of the sensor platform (i.e., sensor These results suggest that quantification estimates taken in aggregate can be partially reconciled between CMS solutions by controlling for the algorithm used to estimate emission rates. This is promising, as long-term averages of CMS-based quantification estimates can be used to create measurement-informed methane inventories that capture site-level intermittency if they are shown to be reliable through repeated evaluation. However, given that only six sites were included in this study, an analysis of more sites is necessary to both verify and generalize these findings to different sites.
