Available in PDF, EPUB and Kindle. Book excerpt: E-region nitric oxide concentrations are known to be greater at high altitudes as compared to low- and midlatitudes. It is suggested that studies of electron concentration data from ionosondes and/or the Chatanika backscatter radar at night, and especially at sunrise, may be able to provide peak nitric oxide concentrations when aurora are determined to be absent.
