abstract = {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 North Atlantic region where the MOZAIC
flights are the most frequent and for which the measurements
are well representative in space and time. The study
investigates the influence of lightning NOx (LNOx) emissions
on large-scale (300–2000 km) plumes (LSPs) of NOy. One
hundred and twenty seven LSPs $(6\%$ of the total MOZAIC NOy
dataset) have been attributed to LNOx emissions. Most of
these LSPs were recorded over North America and the Atlantic
mainly in spring and summer during the maximum lightning
activity occurrence. The majority of the LSPs $(74\%)$ is
related to warm conveyor belts and extra-tropical cyclones
originating from North America and entering the
intercontinental transport pathway between North America and
Europe, leading to a negative (positive) west to east NOy
(O3) zonal gradient with −0.4 (+18) ppbv difference during
spring and −0.6 (+14) ppbv difference in summer. The NOy
zonal gradient can correspond to the mixing of the plume
with the background air. On the other hand, the O3 gradient
is associated with both mixing of background air and with
photochemical production during transport. Such
transatlantic LSPs may have a potential impact on the
European pollution. The remaining sampled LSPs are related
to mesoscale convection over Western Europe and the
Mediterranean Sea $(18\%)$ and to tropical convection
$(8\%).$},
