Carbon and hydrogen isotopic ratios of atmospheric methane in the upper troposphere over the Western Pacific

Carbon and hydrogen isotopic ratios of atmospheric methane in the upper troposphere over the Western Pacific

We present the mixing ratio, &delta;<sup>13</sup>C and &delta;D of atmospheric CH<sub>4</sub> using commercial aircraft in the upper troposphere (UT) over the Western Pacific for the period December 2005–September 2010. The obse...
