- Abstract
- We present observations of stratosphere NOy species from 2002 to 2010 taken by
theMichelson Interferometer for Passive Atmospheric Sounding (MIPAS) and by the Global
Ozone Monitoring by Occultation of Stars (GOMOS) instruments on board ENVISAT. We
jointly used observations of MIPAS NO2, HNO3, N2O5, ClONO2 and N2O, and GOMOS
NO2 and NO3. MIPAS results are part of the MIPAS2D database retrieved adopting a full
2D tomographic approach.We describe the mean distribution and variability of NOy species
in the stratosphere, identifying changes induced by plasma processes. Beside enhancements
due to sporadic solar proton events, we show that winter polar NO2 has an almost linear
relationship with the geomagnetic activity index Ap down to about 10 hPa. This indicates
a dominant role of energetic precipitating particles in the production of upper atmosphere
NOy . The correlation has clear signatures extending to mid latitudes. Partitioning of the
NOy reservoir species are also traced, with HNO3 and N2O5 showing a correlation with Ap
extending to lower altitude within the polar regions. We found no large signatures of an
impact of thunderstorm-induced plasma processes onto monthly means of NOy species in
the stratosphere. (literal)
