Lightning NOx influence on large-scale NOy and O3 plumes observed over the northern mid-latitudes
This paper describes the NOy plumes originating from lightning emissions based on 4 yr (2001–2005) of MOZAIC measurements in the upper troposphere of the northern mid-latitudes, together with ground- and space-based observations of lightning flashes and clouds. This analysis is primarily for the Nor...

The NOy zonal gradient can correspond to the mixing of the plume with the background air.

The remaining sampled LSPs are related to mesoscale convection over Western Europe and the Mediterranean Sea (18%) and to tropical convection (8%).
