AB  - <jats:p>                    Radiocarbon (                    <jats:sup>14</jats:sup>                    C) is a valuable tracer to determine the relative fossil fractions of emitted carbonaceous greenhouse gases, such as CO                    <jats:sub>2</jats:sub>                    and CH                    <jats:sub>4</jats:sub>                    . While atmospheric Δ                    <jats:sup>14</jats:sup>                    CO                    <jats:sub>2</jats:sub>                    measurements have been conducted at multiple sites for several decades, Δ                    <jats:sup>14</jats:sup>                    CH                    <jats:sub>4</jats:sub>                    measurements remain more limited, mainly due to measurement challenges. In addition,                    <jats:sup>14</jats:sup>                    CH                    <jats:sub>4</jats:sub>                    emissions from nuclear power plants (NPPs) can complicate data interpretation. In this study, fortnightly Δ                    <jats:sup>14</jats:sup>                    CH                    <jats:sub>4</jats:sub>                    and Δ                    <jats:sup>14</jats:sup>                    CO                    <jats:sub>2</jats:sub>                    measurements at the Swiss High-Altitude Research Station Jungfraujoch (JFJ, about 3500 m a.s.l.) between 2019 and 2024 are presented. Over this period, Δ                    <jats:sup>14</jats:sup>                    CH                    <jats:sub>4</jats:sub>                    values showed an increase from 350 ± 19 ‰ to 381 ± 13 ‰, while Δ                    <jats:sup>14</jats:sup>
