Abstract : In this work a number of studies are made of D-region electron density profiles measured by the wave interaction technique at The Pennsylvania State University. Changes in electron density observed during a solar flare on October 21, 1968 are analyzed to determine an upper limit to the nitric oxide concentration. This limit is about 30,000,000 per cc at 80 kilometers. This result is then applied to the normal diurnal variation of electron density, and it is shown that the diurnal variation is consistent with this value of NO. Some electron density measurements during a stratospheric warming are also presented. (Author)
