Impacts of UV irradiance and medium-energy electron precipitation on the North Atlantic oscillation during the 11-year solar cycle
Guttu, Sigmund; Orsolini, Yvan; Stordal, Frode; Otterå, Odd Helge; Omrani, Nour-Eddine; Tartaglione, Nazario; Verronen, Pekka T.; Rodger, Craig J.; Clilverd, Mark A. (Peer reviewed; Journal article, 2021)Observational studies suggest that part of the North Atlantic Oscillation (NAO) variability may be attributed to the spectral ultra-violet (UV) irradiance variations associated to the 11-year solar cycle. The observed ... -
Observations of nitric oxide in the Antarctic middle atmosphere during recurrent geomagnetic storms
Newnham, David A.; Espy, Patrick Joseph; Clilverd, Mark A.; Rodger, Craig J.; Seppälä, Annika; Maxfield, David J.; Hartogh, Paul; Straub, Corinne; Holmén, Kim; Horne, Richard B. (Journal article; Peer reviewed, 2013)We report ground-based measurements of the polar middle atmosphere made using a 230–250 GHz passive microwave radiometer deployed at Troll station (72°01′S 02°32′E, L shell of L = 4.8), Antarctica. Our observations show ...
