AB - <jats:p> &lt;p&gt;Measurements of stable isotope ratios of atmospheric CH&lt;sub&gt;4&lt;/sub&gt;&amp;#160;(&amp;#948;&lt;sup&gt;13&lt;/sup&gt;C-CH&lt;sub&gt;4&lt;/sub&gt;, &amp;#948;D-CH&lt;sub&gt;4&lt;/sub&gt;) have been utilized to evaluate contributions of individual CH&lt;sub&gt;4&lt;/sub&gt;&amp;#160;sources and sinks to global atmospheric CH&lt;sub&gt;4&lt;/sub&gt;&amp;#160;budget. However, given the uncertainty of both the source isotope signatures and kinetic isotope effects, recent estimates of the global atmospheric CH&lt;sub&gt;4&lt;/sub&gt;&amp;#160;budget using stable isotope observations are still inconclusive&lt;span&gt;.&amp;#160;&lt;/span&gt;Radiocarbon measurements (&amp;#916;&lt;sup&gt;14&lt;/sup&gt;C-CH&lt;sub&gt;4&lt;/sub&gt;) could provide &lt;span&gt;stronger&amp;#160;&lt;/span&gt;additional&amp;#160;&lt;span&gt;constraint&amp;#160;&lt;/span&gt;&lt;span&gt;on&amp;#160;&lt;/span&gt;&lt;span&gt;the&amp;#160;&lt;/span&gt;&lt;span&gt;fossil-fuel&amp;#160;&lt;/span&gt;CH&lt;sub&gt;4&lt;/sub&gt;&amp;#160;&lt;span&gt;sources &lt;/span&gt;(i.e.,&lt;sup&gt;14&lt;/sup&gt;C-free)&lt;span&gt;, but the uncertainty of &lt;sup&gt;14&lt;/sup&gt;CH&lt;sub&gt;4&lt;/sub&g
