Using a database of aeronomical parameters measured by the Atmosphere Explorer-C satellite, we deduce a temperature dependence of the reaction rate coefficient for the charge exchange of O+(2D) with N2, O+(2D)+N2 k O+N2+. The results indicate that the Atmosphere Explorer values determined over the temperature range ~700 to 1900 ¿K, are not in conflict with the laboratory measurements made at higher temperatures. From these results, we show that the rate coefficient can be represented by k(Teff)?3)¿10-11 cm3 sec-1 for 700Keff<1200K and k(Teff)=2.8¿10-10-2.1¿10-10(Teff/300) + 4.2¿10-11(Teff/300)2 for 1200Keff<2300K The shape of the temperature variatio is found to be similar to that for the ion atom interchange rate coefficient of ground state oxygen ions with N2.
