Sunrise E-region Enhancements from Aurorally Increased NO: Theory


Book Description

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.

The D- and E- Regions


Book Description

The chemistry of the E-region is fairly well understood and even many of the dynamical complications of this region have been successfully modeled on individual bases. Some of the major remaining problems of this region are discussed, in particular the nitric oxide concentration, a gas affecting the ratio of the two major E-region ions, O2(+) and NO(+). The D-region is much simpler than the E-region from a dynamical point of view but extremely much more complex from a chemical standpoint. Recent results from a study of the D-region under bombardment by solar protons is emphasized.
