Enhancement of N 2 O during the October?November 2003 solar proton events

International audience In this paper we present evidence of enhanced N 2 O concentrations in the upper stratosphere/lower mesosphere polar regions after the solar proton events that occurred during October?November 2003.

Description
Summary:International audience In this paper we present evidence of enhanced N 2 O concentrations in the upper stratosphere/lower mesosphere polar regions after the solar proton events that occurred during October?November 2003. The observations were performed by the MIPAS instrument on the Envisat satellite. Simulations performed using the Canadian Middle Atmospheric Model (CMAM) show that such enhancements are most likely produced by the reaction of N( 4 S) with NO 2 , both of which species are largely enhanced just after the solar proton events in the winter polar night.
