Nitric Oxide Response to the April 2010 Electron Precipitation Event: UsingWACCM andWACCM-DWith andWithout Medium-Energy Electrons
Christine Smith-Johnsen, Daniel R. Marsh, Yvan Orsolini +5
Energetic electrons from the magnetosphere deposit their energy in the atmosphere and lead to production of nitric oxide (NO) in the mesosphere and lower thermosphere. We study the…
Nighttime mesospheric ozone enhancements during the 2002 southern hemispheric major stratospheric warming
Christine Smith-Johnsen, Yvan Orsolini, Frode Stordal +2
Sudden Stratospheric Warmings (SSW) affect the chemistry and dynamics of the middle atmosphere. Major warmings occur roughly every second winter in the Northern Hemisphere (NH), bu…
Two mechanisms of stratospheric ozone loss in the Northern Hemisphere, studied using data assimilation of Odin/SMR atmospheric observations
Kazutoshi Sagi, Kristell Pérot, Donal Murtagh +1
Observations from the Odin/Sub-Millimetre Radiometer (SMR) instrument have been assimilated into the DIAMOND model (Dynamic Isentropic Assimilation Model for OdiN Data), in order t…
Modelling the descent of nitric oxide during the elevated stratopause event of January 2013
Yvan J. Orsolini, Varavut Limpasuvan, Kristell Pérot +5
Using simulations with a whole-atmosphere chemistry-climate model nudged by meteorological analyses, global satellite observations of nitrogen oxide (NO) and water vapour by the Su…
Observations of planetary waves in the mesosphere-lower thermosphere during stratospheric warming events
N. H. Stray, Y. J. Orsolini, P. J. Espy +2
This study investigates the effect of stratospheric sudden warmings (SSWs) on planetary wave (PW) activity in the mesosphere-lower thermosphere (MLT). PW activity near 95 km is der…
Observations of gravity wave forcing of themesopause region during the January 2013 major Sudden Stratospheric Warming
R. J. deWit, R. E. Hibbins, P. J. Espy +3
Studies of vertical and interhemispheric coupling during Sudden Stratospheric Warmings (SSWs) suggest that gravity wave (GW) momentum flux divergence plays a key role in forcing th…
