The NRL (Naval Research Laboratory) Data Base of Oblique-Incidence Soundings of the Ionosphere

Abstract

The Naval Research Laboratory has participated in a number of field exercises in support of HF communications, HF Direction Finding (HFDF), and HF Single-Site-Location (HF-SSL) systems development since 1980. During these exercises, the NRL support has included the documentation of ionospheric channel information through collection of Oblique-Incidence-Sounding (OIS) data. Data have been obtained over two distinct epochs of solar activity. The first group, obtained between 1980 and 1982, was obtained for a period of high solar activity. The second group of data obtained between 1986 and the present, corresponds to relatively low or moderate activity. This report describes a collection of approximately 167,000 ionograms in terms of the environmental conditions under which they were obtained. It is planned to make these data sets available as a resource to qualified researchers. Keywords: Ionospheric soundings; Oblique incidence sounding; Database; Ionosphere; Frequency management; High frequency; Ionograms.
