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...
