In this campaign, three measurement-based quantification methods were applied at gas leak locations in Hamburg, Germany. In this virtual tour, we show examples of four types of gas leak locations: (i) a location with large under surface methane accumulation, (ii) a location were methane signals were lower than detection threshold of mobile method, (iii) a location where methane signals showed high variables for mobile methods and (iv) a locations where two gas leaks were detected on the same street. The other locations in this study* were categorized under one of these classes. The results of this study show a possible low-bias inventoried emission report of gas leaks in Germany.
