Abstract
The large data base of aeronomic parameters measured by the Atmosphere Explorer C, D, and E satellites since December 1973 has been used to determine a number of reaction rate coefficients highly relevant to our understanding of thermospheric chemistry. In this paper we review the results for ionic rate coefficients for recombination of NO+, O2+, and N2+, for reactions of O+ + N2, N2+ + O, and O++ + O, and for various reactions involving O+D) and O+P) ions with O and N2.
