Origin of the January–April 2004 increase in stratospheric NO2 observed in the northern polar latitudes
International audience Large increase in stratospheric NO2 content has been observed during the 2003–2004 Arctic winter. The first one, in early November 2003 is well documented and is due to a strong solar protons event. A second event occurred on January 22, 2004, leading to a large amount of NO2...
