Global ground-based tropospheric ozone measurements: reference data and individual site trends (2000–2022) from the TOAR-II/HEGIFTOM project Open
Tropospheric ozone trends from models and satellites are found to diverge. Ground-based (GB) observations are used to reference models and satellites, but GB data themselves might display station biases and discontinuities. Reprocessing wi…

The use of δ <sup>13</sup>C in CO to determine removal of CH<sub>4</sub> by Cl radicals in the atmosphere <sup>*</sup> Open
The reaction of CH 4 with chlorine (Cl) radicals in the atmosphere is associated with an extraordinarily strong isotopic fractionation, where 12 CH 4 reacts about 70 ‰ faster with Cl than 13 CH 4 . Therefore, although the Cl-based sink of …
