Short summary
To reduce the climate impact of human activities, it is crucial to attribute changes in atmospheric gases to anthropogenic emissions. We present an advanced method to determine the contribution of emissions to OH and HO2 concentrations. Compared to the former version, it contains the main reactions of the OH and HO2 chemistry in the troposphere and stratosphere, introduces the tagging of the H radical and closes the budget of the sum of all contributions and the total concentration.
