Abstract
The behavior of mesospheric odd nitrogen species during and following relativistic and diffuse auroral precipitation events is simulated Below 75 km nitric oxide is enhanced in proportion to the ion pair production function associated with the electron precipitation and the length of the event. Nitrogen dioxide and nitric acid are also enhanced At 65 lan the percentage ofodd nitrogen for N is 0.1%, HNO3 is 1.6%, NO2 is 15%, and NO is 83.3%. Between 75 and 85 lan,NO is depleted during particle events due to the faster destruction of NO by N relative to the production of NO by N reacting with O-2. Recovery of NO depends on transport from the lower thermosphere, whereNO is produced in abundant amounts during particle events. (C) 2000 Elsevier Science Ltd. All rights reserved.
