Assuming random timing, some portion of these emissions will be transported by the wind and increase methane concentrations seen by the Solution 2 sensor, increasing Solution 2 estimates. The impact is unknown; in this study we assume these emissions are suciently random and mixed that Solution 2 detects methane enhancements that are representative of mean emissions from these sources. In contrast, these emission events create insucient plumes to be detected during a Solution 1 overight, and have minimal impact on Solution 1 estimates. Therefore, to compare the two solutions, we add an estimate of these emissions to Solution 1.
