Planetary Wave Oscillations Observed in Ozone from Troll Station Antartica
Kleinknecht, Nora (Master thesis, 2010)This thesis investigates the possibility of tracing planetary waves with ozone. The mixing ratio of ozone is sensitive to variations of its environment introduced by waves due to its short chemical lifetime. Ground-based ... -
Quasi-16-day period oscillations observed in middle atmospheric ozone and temperature in Antarctica
Demissie, Teferi Dejene; Kleinknecht, Nora; Hibbins, Robert; Espy, Patrick Joseph; Straub, Corinne (Journal article; Peer reviewed, 2013)Nightly averaged mesospheric temperature derived from the hydroxyl nightglow at Rothera station (67°34' S, 68°08' W) and nightly midnight measurements of ozone mixing ratio obtained from Troll station (72°01' S, 2°32' E) ... -
The climatology of zonal wave numbers 1 and 2 planetary wave structure in the MLT using a chain of Northern Hemisphere SuperDARN radars
Kleinknecht, Nora; Espy, Patrick Joseph; Hibbins, Robert (Journal article; Peer reviewed, 2014)The zonal wave components 1 and 2 were extracted from the meridional wind along the latitude band of 51–66°N for the years 2000–2008 using eight Super Dual Auroral Radar Network (SuperDARN) radars spanning longitudes from ...
