Interactive comment on “The effect of lightning NOx production on surface ozone in the continental United States” by B. Kaynak et al

This is an interesting model study of the sensitivity of surface ozone to NOx produced by lightning. The conclusion, that on average the contribution is relatively minor, has policy implications because it implies that the background O3 (which cannot be regulated) is not much enhanced by lightning. The paper is suitable for publication, but could benefit by additional discussion of several topics.

The effect of lightning NOx production on surface ozone in the continental United States

Lightning NOx emissions calculated using the US National Lightning Detection Network data were found to account for 30% of the total NOx emissions for July–August 2004, a period chosen both for having higher lightning NOx production and high ozone levels, thus maximizing the likelihood that such emissions could impact peak ozone levels. Including such emissions led to modest, but sometimes sign...

Interannual variability in tropical tropospheric ozone and OH: The role of lightning

[1] Nitrogen oxide radicals (NOx) produced by lightning are natural precursors for the production of the dominant tropospheric oxidants, OH and ozone. Observations of the interannual variability (IAV) of tropical ozone and of global mean OH (from the methyl chloroform proxy) offer a window for understanding the sensitivity of ozone and OH to environmental factors. We present the results of simu...

Sensitivity of the NOy budget over the United States to anthropogenic and lightning NOx in summer

[1] We examine the implications of new estimates of the anthropogenic and lightning nitrogen oxide (NOx) source for the budget of oxidized nitrogen (NOy) over the United States in summer using a 3‐D global chemical transport model (Model of Ozone and Related Tracers‐4). As a result of the Environmental Protection Agency (EPA) State Implementation call, power plant NOx emissions over the eastern...

Dynamic-chemical coupling of the upper troposphere and lower stratosphere region.

The importance of the interaction between chemistry and dynamics in the upper troposphere and lower stratosphere for chemical species like ozone is investigated using two chemistry-climate models and a Lagrangian trajectory model. Air parcels from the upper troposphere, i.e. regions of lightning and aircraft emissions, are able to be transported into the lowermost stratosphere (LMS). Trajectory...
