Positive ions in the stratosphere

Arnold, F., D. Krankowsky, and K. H. Marien, First Mass Spec-trometric Measurements of Positive Ions in the Stratosphere, Nature, 267, 30-31 (1977). 

Figure 7.23. Schematic of the aeronomic reactions of positive ions in the stratosphere. From Ferguson (1979).

Table 7.5 shows the mass of positive ions measured in the stratosphere by mass spectrometry and the identification of the corresponding ions. Comprehensive reviews of the chemistry and observations of stratospheric positive ions are provided by Arnold (1980), Arijs (1983), and Arijs (1992). Models of positive ions in the stratosphere have been developed by Brasseur and Chatel (1983), Arijs and Brasseur (1986), Beig and Chakrabarty (1988), Beig et al. (1993a), etc.
