The flowing afterglow technique for ion-molecule reaction studies developed at NOAA with DNA support has been extended to allow measurement at temperatures up to 900K and relative kinetic energies up to several electron volts. A number of important ionospheric reactions have been measured using these techniques, including most of the important E- and F-region binary positive ion reactions. The NOAA D-region negative ion reaction scheme has been extended to include more effects of hydration and reactions of trace constituents. The reaction NO - H2O OH to H3O NO2 has been found to be too slow to be of much D-region significance. Measurements of the charge-transfer of electronically excited O2 with N2, have been carried out as a function of energy.
