Finally, we consider cumulative quantification error over the one-month study period. When considering only small emissions (≤ 1 kg/hr), the framework underestimates cumulative emissions by 38.5%. When considering only large emissions (> 1 kg/hr), the framework underestimates cumulative emissions by 0.2%. Overall, when including both false positives and false negatives and both small and large emissions, the framework underestimates cumulative emissions by 5.5%.
