A discussion on the determination of atmospheric OH and its trends (2002)

Jöckel, P., Brenninkmeijer, C. A. M., Crutzen, P. J.

The global hydroxyl radical distribution largely determines the oxidation efficiency of the atmosphere and, together with their sources and atmospheric transport, the distributions and lifetimes of...

What does the global mean OH concentration tell us? (2001)

M. G. Lawrence, P. Jöckel, R. Von Kuhlmann

The global mean OH concentration ([OH]GM) has been used as an indicator of the atmospheric oxidizing efficiency and its changes over time. It is also used for evaluating the performance of...
