Effects of enhanced downwelling of NOx on Antarctic upper-stratospheric ozone in the 21st century

Autor: V. Maliniemi, H. Nesse Tyssøy, C. Smith-Johnsen, P. Arsenovic, D. R. Marsh

Publikováno v: Atmospheric Chemistry and Physics, Vol 21, Pp 11041-11052 (2021)

Ozone is expected to fully recover from the chlorofluorocarbon (CFC) era by the end of the 21st century. Furthermore, because of anthropogenic climate change, a cooler stratosphere decelerates ozone loss reactions and is projected to lead to a super

The Predictive Capabilities of the Auroral Electrojet Index for Medium Energy Electron Precipitation

Autor: H. Nesse Tyssøy, N. Partamies, E. M. Babu, C. Smith-Johnsen, J. A. Salice

Publikováno v: Frontiers in Astronomy and Space Sciences, Vol 8 (2021)

The chemical imprint of the energetic electron precipitation on the atmosphere is now acknowledged as a part of the natural forcing of the climate system. It has, however, been questioned to which degree current proxies are able to quantify the mediu

Production and transport mechanisms of NO in the polar upper mesosphere and lower thermosphere in observations and models

Autor: K. Hendrickx, L. Megner, D. R. Marsh, C. Smith-Johnsen

Publikováno v: Atmospheric Chemistry and Physics, Vol 18, Pp 9075-9089 (2018)

A reservoir of nitric oxide (NO) in the lower thermosphere efficiently cools the atmosphere after periods of enhanced geomagnetic activity. Transport from this reservoir to the stratosphere within the winter polar vortex allows NO to deplete ozone

Determining Latitudinal Extent of Energetic Electron Precipitation Using MEPED On-Board NOAA/POES

Autor: E. M. Babu, H. Nesse Tyssøy, C. Smith‐Johnsen, V. Maliniemi, J. A. Salice, R. M. Millan, I. G. Richardson

Journal of Geophysical Research (JGR): Space Physics

Energetic Electron Precipitation (EEP) from the plasma sheet and the radiation belts ionizes the polar lower thermosphere and mesosphere. EEP increases the production of NOx and HOx, which will catalytically destroy ozone, an important element of atm

Precipitating auroral and radiation belt electrons are considered to play an important part in the natural forcing of the middle atmosphere with a possible impact on the climate system. Recent studies suggest that this forcing is underestimated in cu
