In situ Mass Spectrometry and Ion Chemistry in the Stratosphere and Troposphere
Abstract
Ions are generated in the atmosphere by a variety of ionization processes. These include photoionization, collisions with energetic particles and cosmic rays, and at ground level ionization from energetic particles released from radioactive decay of radon and other gases (1-10). Although the ionization process varies, the primary ions are usually similar. The primary ions result from ionization of the abundant neutrals N2 and 0, producing N+2, N+, O+2 and O+. A notable exception is the ionization of NO by Lyman a near the mesopause. The subsequent chemistry is then controlled by less abundant neutrals. As will be shown later, neutrals in the part-per-quadrillion range can affect the ion composition. Ions are lost by recombination with electrons or ions, and in the lower atmosphere loss to surfaces such as aerosols and the ground becomes important.
