Urban emissions remain an underexamined part of the methane budget. Here we present and interpret aircraft observations of six old and leak-prone major cities along the East Coast of the United States. We use direct observations of methane (CH<sub>4</sub>), carbon dioxide (CO<sub>2</sub>), carbon monoxide (CO), ethane (C<sub>2</sub>H<sub>6</sub>), and their correlations to quantify CH<sub>4</sub> emissions and attribute to natural gas. We find the five largest cities emit 0.85 (0.63, 1.12) Tg CH ...[more]
