Scientific paper

The intense solar eruptive events in January 2005 caused atmospheric changes in the polar regions due to solar energetic particles associated with these events. Solar particles (primarily protons) produced ionizations, excitations, dissociations, and dissociative ionizations of the mesospheric background constituents, which led to the production of HOx (H, OH, and HO2) through a series of ion-molecule reactions. These odd hydrogen constituents led to depletions of ozone through catalytic reactions. The Aura MLS instrument observed substantial mesospheric increases in OH from January 17-22, 2005, along with associated decreases ozone (up to 50% between 65 and 75 km). Larger changes were observed in the north compared with the south polar regions. To the best of our knowledge, these are the first observations of OH production as a result of solar particle events and offer a chance to test our chemical understanding of the mesosphere.
