A two-dimensional photochemical transport model which has inputs that characterize the odd nitrogen production associated with Galactic cosmic rays, solar particle events (SPEs), and lower thermospheric contributions (auroral electrons and solar EUV and soft X-rays) is used to compute odd nitrogen concentrations in the polar middle atmosphere from 1 January 1970 to 31 December 1994. The authors are able to separate out of the total odd nitrogen budget the contributions of the energetic charged particles according to type. The SPE contributions to annual average odd nitrogen concentrations in the polar stratosphere (latitudes >50°) are computed to be significant (>10%) only for the larger events of August 1972 and October 1989. The SPE and thermospheric contributions to odd nitrogen concentrations in the polar middle atmosphere are found to be hemispherically asymmetric. An attempt has been made to compare the modeled odd nitrogen of the polar middle atmosphere to an ultra-high resolution polar ice cap nitrate sequence to examine the hypothesis that the nitrate sequences exhibit a signal associated with energetic particles.
